1 3479 206 IDENTIFICATION OF BIOACTIVE METABOLITES AND EVALUATION OF IN VITRO ANTI-INFLAMMATORY AND IN VIVO ANTINOCICEPTIVE AND ANTIARTHRITIC ACTIVITIES OF ENDOPHYTE FUNGI ISOLATED FROM ELAEOCARPUS FLORIBUNDUS BLUME. ETHNOPHARMACOLOGICAL RELEVANCE: FUNCTIONAL DISABILITY ASSOCIATED WITH RHEUMATOID ARTHRITIS (RA), A CHRONIC INFLAMMATORY AUTOIMMUNE DISEASE IS A CHALLENGING CONCERN IN HEALTHCARE SYSTEMS. ALONG WITH ENVIRONMENTAL FACTORS AND EPIGENETIC DISORDERS, MULTIPLE PATHWAYS ARE REPORTED AS PROMINENT MECHANISM FOR THE PROGRESSION OF RA SYMPTOMS INCLUDING; PAIN, SWELLING AND STIFFNESS OF JOINTS. ELAEOCARPUS FLORIBUNDUS BLUME HAS BEEN USED AS A FOLKLORE MEDICINE FOR RA FROM ANCIENT TIMES. THIS PLANT HARBOURS A SUITE OF ENDOPHYTIC FUNGI THAT PRODUCE A RANGE OF METABOLITES OF POTENTIAL INTEREST. THUS, FOR THE ESTABLISHMENT OF A SCIENTIFIC BASIS FOR THIS FOLKLORE USE, IT IS ESSENTIAL TO FIND OUT THE INVOLVEMENT, IF ANY, OF THE ENDOPHYTIC FUNGI LIVING IN THIS PLANT AND THE METABOLITES THEY ELABORATE, FOR THE MANAGEMENT OF RA. AIM OF THE STUDY: THIS STUDY WAS DESIGNED TO ISOLATE, IDENTIFY AND EVALUATE THE IN VITRO ANTI-INFLAMMATORY AND IN VIVO ANTINOCICEPTIVE AND ANTIARTHRITIC ACTIVITIES OF THE COMPOUNDS PRODUCED BY THE ENDOPHYTIC FUNGI LIVING IN DIFFERENT PARTS OF ELAEOCARPUS FLORIBUNDUS BLUME. MATERIALS AND METHODS: ENDOPHYTIC FUNGI FROM DIFFERENT PARTS OF THE PLANT WERE ISOLATED AND CULTURED FOR THE PRODUCTION OF SECONDARY METABOLITES. CHROMATOGRAPHICALLY FRACTIONATED FUNGAL EXTRACTS WERE ASSESSED FOR ANTI-INFLAMMATORY AND ANTINOCICEPTIVE ACTIVITIES. FOR THE EVALUATION OF ANTI-INFLAMMATORY ACTIVITY, IN VITRO CYCLOOXYGENASE (COX1/COX2) AND 5-LIPOXYGENASE (5-LOX) INHIBITORY ASSAYS WERE PERFORMED. FOR THE EVALUATION OF IN VIVO ANTINOCICEPTIVE ACTIVITY, HOT PLATE ACETIC ACID INDUCED WRITHING, AND FORMALIN INDUCED PAW LICKING METHODS WERE ADOPTED, WHEREAS COMPLETE FREUND'S ADJUVANT (CFA) INDUCED POLY-ARTHRITIC METHOD WAS ADOPTED FOR THE EVALUATION OF ANTIARTHRITIC ACTIVITY. THE MOST EFFECTIVE FRACTION WAS ANALYZED BY LIQUID CHROMATOGRAPHY-MASS SPECTROSCOPY (LC-MS) IN SEARCH OF THE BIOACTIVE EXTRACELLULAR METABOLITES. RESULTS: FIVE ENDOPHYTIC FUNGI VIZ. ASPERGILLUS FUMIGATUS, ASPERGILLUS NIGER, RHIZOCTONIA ORYZAE, RHIZOPUS ORYZAE, AND SYNCEPHALASTRUM RACEMOSUM WERE ISOLATED. COX1/COX2 AND 5-LOX INHIBITORY ASSAYS STATE THAT THE ASPERGILLUS NIGER FRACTION POSSESSES THE GREATEST ACTIVITY AGAINST THESE ENZYMES OF INFLAMMATORY PROCESS. IN VIVO ANTINOCICEPTIVE SHOWED SIGNIFICANT (***P<0.001) REDUCTION OF PAIN IN A DOSE DEPENDENT MANNER. AS WELL, SIGNIFICANT (***P<0.001) REDUCTION OF PAW VOLUME WAS OBSERVED IN CFA INDUCE POLY-ARTHRITIC TEST. LC/MS ANALYSIS OF THE ASPERGILLUS NIGER FRACTION REVEALED THE PRESENCE OF BIOACTIVE COMPOUNDS INCLUDING TENSYUIC ACID, HEXYLITACONIC ACID, CHLOROGENIC ACID, NIGRAGILLIN, TMC-256C1, ASNIPYRONE B, ASPERENONE, FUMARIC ACID AND FUSARUBIN, ALL HAVING REPORTED PHARMACOLOGICAL ACTIVITIES. CONCLUSION: THE PRESENT STUDY DEMONSTRATES THAT SECONDARY METABOLITES PRODUCED BY ENDOPHYTIC FUNGI LIVING IN VARIOUS PARTS OF ELAEOCARPUS FLORIBUNDUS BLUME HAD POTENTIAL TO RELIEF PAIN AND INFLAMMATION. THE ENDOPHYTES WERE FOUND TO CONTAIN MULTIPLE BIOMOLECULES EFFECTIVE IN RHEUMATOID ARTHRITIS. THESE FINDINGS PROVIDE A RATIONALE FOR THE FOLKLORE USE OF THE PLANT IN THE MANAGEMENT OF RHEUMATOID ARTHRITIS.	2021	

2 2080  35 EPIGENETIC DNA METHYLATION OF EBI3 MODULATES HUMAN INTERLEUKIN-35 FORMATION VIA NFKB SIGNALING: A PROMISING THERAPEUTIC OPTION IN ULCERATIVE COLITIS. ULCERATIVE COLITIS (UC), A SEVERE CHRONIC DISEASE WITH UNCLEAR ETIOLOGY THAT IS ASSOCIATED WITH INCREASED RISK FOR COLORECTAL CANCER, IS ACCOMPANIED BY DYSREGULATION OF CYTOKINES. EPSTEIN-BARR VIRUS-INDUCED GENE 3 (EBI3) ENCODES A SUBUNIT IN THE UNIQUE HETERODIMERIC IL-12 CYTOKINE FAMILY OF EITHER PRO- OR ANTI-INFLAMMATORY FUNCTION. AFTER HAVING RECENTLY DEMONSTRATED THAT UPREGULATION OF EBI3 BY HISTONE ACETYLATION ALLEVIATES DISEASE SYMPTOMS IN A DEXTRAN SULFATE SODIUM (DSS)-TREATED MOUSE MODEL OF CHRONIC COLITIS, WE NOW AIMED TO EXAMINE A POSSIBLE FURTHER EPIGENETIC REGULATION OF EBI3 BY DNA METHYLATION UNDER INFLAMMATORY CONDITIONS. TREATMENT WITH THE DNA METHYLTRANSFERASE INHIBITOR (DNMTI) DECITABINE (DAC) AND TNFALPHA LED TO SYNERGISTIC UPREGULATION OF EBI3 IN HUMAN COLON EPITHELIAL CELLS (HCEC). USE OF DIFFERENT SIGNALING PATHWAY INHIBITORS INDICATED NFKAPPAB SIGNALING WAS NECESSARY AND PROPORTIONAL TO THE SYNERGISTIC EBI3 INDUCTION. MALDI-TOF/MS AND HPLC-ESI-MS/MS ANALYSIS OF DAC/TNFALPHA-TREATED HCEC IDENTIFIED IL-12P35 AS THE MOST PROBABLE BINDING PARTNER TO FORM A FUNCTIONAL PROTEIN. EBI3/IL-12P35 HETERODIMERS (IL-35) INDUCE THEIR OWN GENE UPREGULATION, SOMETHING THAT WAS INDEED OBSERVED IN HCEC CULTURED WITH MEDIA FROM PREVIOUSLY DAC/TNFALPHA-TREATED HCEC. THESE RESULTS SUGGEST THAT UNDER INFLAMMATORY AND DEMETHYLATING CONDITIONS THE UPREGULATION OF EBI3 RESULTS IN THE FORMATION OF ANTI-INFLAMMATORY IL-35, WHICH MIGHT BE CONSIDERED AS A THERAPEUTIC TARGET IN COLITIS.	2021	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                      
3 2977  31 GENETIC AND PHENOTYPIC CHARACTERIZATION OF IN-HOST DEVELOPED AZOLE-RESISTANT ASPERGILLUS FLAVUS ISOLATES. ASPERGILLUS FLAVUS IS A PATHOGENIC FUNGAL SPECIES THAT CAN CAUSE PULMONARY ASPERGILLOSIS, AND TRIAZOLE COMPOUNDS ARE USED FOR THE TREATMENT OF THESE INFECTIONS. PROLONGED EXPOSURE TO AZOLES MAY SELECT FOR COMPENSATORY MUTATIONS IN THE A. FLAVUS GENOME, RESULTING IN AZOLE RESISTANCE. HERE, WE CHARACTERIZE A SERIES OF 11 ISOGENIC A. FLAVUS STRAINS ISOLATED FROM A PATIENT WITH PULMONARY ASPERGILLOSIS. OVER A PERIOD OF THREE MONTHS, THE INITIALLY AZOLE-SUSCEPTIBLE STRAIN DEVELOPED ITRACONAZOLE AND VORICONAZOLE RESISTANCE. SHORT TANDEM REPEAT ANALYSIS AND WHOLE-GENOME SEQUENCING REVEALED THE HIGH GENETIC RELATEDNESS OF ALL ISOLATES, INDICATING AN INFECTION WITH ONE SINGLE ISOLATE. IN CONTRAST, THE ISOLATES WERE MACROSCOPICALLY HIGHLY DIVERSE, SUGGESTING AN ADAPTATION TO THE ENVIRONMENT DUE TO (EPI)GENETIC CHANGES. THE WHOLE-GENOME SEQUENCING OF SUSCEPTIBLE AND AZOLE-RESISTANT STRAINS SHOWED A NUMBER OF MUTATIONS THAT MIGHT BE ASSOCIATED WITH AZOLE RESISTANCE. THE MAJORITY OF RESISTANT STRAINS CONTAIN A Y119F MUTATION IN THE CYP51A GENE, WHICH CORRESPONDS TO THE Y121F MUTATION FOUND IN A. FUMIGATUS. ONE AZOLE-RESISTANT STRAIN DEMONSTRATED A DIVERGENT SET OF MUTATIONS, INCLUDING A V99A MUTATION IN A MAJOR FACILITATOR SUPERFAMILY (MSF) MULTIDRUG TRANSPORTER (AFLA 083950).	2021	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                            
4 6636  49 UNRAVELING A NEW PLAYER IN MULTIPLE SCLEROSIS PATHOGENESIS: THE RNA-BINDING PROTEIN HUR. BACKGROUND: ELAV-LIKE PROTEINS ARE A SMALL FAMILY OF RNA-BINDING PROTEINS THAT ARE FUNDAMENTAL PLAYERS IN POST-TRANSCRIPTIONAL MECHANISMS AND ARE INVOLVED IN THE PATHOGENESIS OF NEUROLOGIC AND PSYCHIATRIC DISORDERS. HUR, THE UBIQUITOUSLY EXPRESSED MEMBER OF THE FAMILY, IS ALSO IMPLICATED IN SUSTAINING INFLAMMATION AND INFLAMMATORY DISEASES, SUPPORTING THE PRODUCTION OF PRO-INFLAMMATORY CYTOKINES. INFLAMMATION PLAYS A CENTRAL ROLE IN MULTIPLE SCLEROSIS (MS), WHICH REPRESENTS THE MOST COMMON CAUSE OF PERMANENT PHYSICAL DISABILITY IN YOUNG ADULTS. MS IS A CHRONIC AUTOIMMUNE DISEASE AFFECTING THE CENTRAL NERVOUS SYSTEM, WITH A COMPLEX AETIOLOGY INVOLVING GENETIC, ENVIRONMENTAL AND EPIGENETIC FACTORS. NO DATA ARE AVAILABLE ON THE POTENTIAL ENTANGLEMENT OF HUR IN MS PATHOGENESIS IN PATIENTS. IN THE PRESENT WORK, WE AIMED AT EXPLORING HUR PROTEIN LEVELS IN PERIPHERAL BLOOD MONONUCLEAR CELLS (PBMCS) FROM MS PATIENTS, COMPARED TO HEALTHY CONTROLS. TO FURTHER ELUCIDATE THE POSSIBLE INVOLVEMENT OF HUR IN MS, WE ALSO INVESTIGATED THE RELATIONSHIP BETWEEN THIS SPECIFIC RNA-BINDING PROTEIN AND HSP70-2 PROTEIN, ALSO CONSIDERING THE HSP70-2 RS1061581 POLYMORPHISM, GIVEN THAT HSP70-2 MRNA HAS BEEN REPORTED AS A HUR TARGET AND THIS SPECIFIC POLYMORPHISM TO BE ASSOCIATED WITH MS RISK. METHODS: ALLELES AND GENOTYPES FOR HSP70-2 RS1061581 POLYMORPHISM WERE ASSESSED, BY USING A POLYMERASE CHAIN REACTION-RESTRICTION FRAGMENT LENGTH POLYMORPHISM, FOLLOWED BY DIGESTION WITH RESTRICTION ENZYME, IN MS PATIENTS AND HEALTHY CONTROLS. PBMCS FROM A SUBGROUP OF PATIENTS AND CONTROLS WERE USED TO EVALUATE HUR AND HSP70-2 PROTEIN CONTENT BY WESTERN BLOT. RESULTS: PBMCS FROM 52 MS PATIENTS HAD A LOWER HUR AND HIGHER HSP70-2 PROTEIN CONTENT COMPARED TO 43 HEALTHY CONTROLS. AN INCREASE OF 100 UNITS OF HUR SIGNIFICANTLY DECREASED THE RISK OF DEVELOPING MS BY 9.8% (OR: 0.902, 95% CI: 0.83-0.98), CONTROLLING FOR HSP70-2 PROTEIN EXPRESSION, HSP70-2 RS1061581 GENOTYPE, AGE AND SEX. MOREOVER, HOLDING HUR LEVELS, AN INCREASE OF 100 UNITS OF HSP70-2 PROTEIN SIGNIFICANTLY INCREASED THE MS RISK BY 18.1% (OR: 1.181, 95% CI: 1.03-1.36) AND THE GENETIC SUSCEPTIBILITY OF DEVELOPING MS FOR HSP70-2 RS1061581 GG CARRIERS IS CONFIRMED. OF INTEREST, MS PATIENTS WITH A MODERATE TO SEVERE FORM OF MS (MSSS >/= 3) SHOWED A TREND TOWARDS A REDUCTION OF HUR PROTEIN LEVELS COMPARED TO PATIENTS WITH MILD DISEASE SEVERITY (MSSS < 3). CONCLUSIONS: HUR PROTEIN LEVELS ARE REDUCED IN MS PATIENTS COMPARED TO HEALTHY SUBJECTS, AND THE PROTEIN AMOUNT MAY CONTINUE TO DECLINE WITH DISEASE PROGRESSION, SUGGESTING A PUTATIVE ROLE OF THIS RNA-BINDING PROTEIN. MOREOVER, OUR RESULTS SUGGEST THAT MS PATHOLOGY MAY HAVE DISRUPTED THE LINK BETWEEN HUR AND ITS TARGET TRANSCRIPT HSP70-2. IT WILL BE IMPORTANT TO FURTHER EXPLORE THE EXACT ROLE OF HUR IN MS, CONSIDERING THE COMPLEX INTERPLAY WITH OTHER RNA-BINDING FACTORS AND TARGET MRNAS.	2020	
                                                                                                                                                                                                                                                                                                                                                                        
5 1282  38 DECIPHERING THE ACTIVE CONSTITUENTS OF DABUSHEN DECOCTION OF AMELIORATING OSTEOARTHRITIS VIA PPARGAMMA PRESERVATION BY TARGETING DNMT1. OSTEOARTHRITIS (OA) IS A MULTIFACTORIAL AND CHRONIC DEGENERATIVE JOINT DISEASE. DUE TO THE ADVERSE EFFECTS OF CURRENTLY USED DRUGS, A SAFER AND MORE EFFECTIVE THERAPY FOR TREATING OA IS NEEDED. PEROXISOME PROLIFERATOR-ACTIVATED RECEPTOR-GAMMA (PPARGAMMA) IS A KEY PROTEIN PROTECTING CARTILAGE. DNMT1-MEDIATED HYPERMETHYLATION OF PPARGAMMA PROMOTER LEADS TO ITS SUPPRESSION. THEREFORE, DNMT1 MIGHT BE AN EFFECTIVE TARGET FOR EXERTING CARTILAGE PROTECTIVE EFFECTS BY REGULATING THE EPIGENETIC EXPRESSION OF PPARGAMMA. DABUSHEN DECOCTION (DD) IS A REPRESENTATIVE PRESCRIPTION OF DUNHUANG ANCIENT MEDICAL PRESCRIPTION, WHICH HAS A POTENTIAL THERAPEUTIC EFFECT ON OA. SO FAR, THE RESEARCH OF THE EFFICACY AND MATERIAL BASIS OF DD IN THE TREATMENT OF OA REMAINS UNCLEAR. IN THIS STUDY, MICRO-CT, HE STAINING, S-O STAINING, AND IMMUNOHISTOCHEMISTRY ANALYSIS WERE USED TO DEMONSTRATE THAT DD INCREASED THE EXPRESSION OF PPARGAMMA AND COLLAGEN SYNTHESIS IN AN OA RAT MODEL. NEXT, THE STRUCTURE OF DNMT1 WAS USED TO SCREEN THE ACTIVE CONSTITUENTS OF DD BY MOLECULAR DOCKING METHOD FOR TREATMENT OA. SEVEN POTENTIAL ACTIVE CONSTITUENTS, INCLUDING ISOLIQUIRITIGENIN, EMODIN, TAXIFOLIN, CATALPOL, ALISOL A, ZINGERONE, AND SCHISANDRIN C WERE HITED. THE PROTECTIVE EFFECT OF THE POTENTIAL ACTIVE CONSTITUENTS TO CHONDROCYTES WERE EVALUATED BY PROTEIN CAPILLARY ELECTROPHORESIS, IMMUNOFLUORESCENCE ASSAYS, AND EX VIVO CULTURE OF RAT KNEE CARTILAGE. THE FIVE CONSTITUENTS, SUCH AS ALISOL A, EMODIN, TAXIFOLIN, ISOLIQUIRITIGENIN, AND SCHISANDRIN C COULD PROMOTE THE EXPRESSION OF PPARGAMMA AND AMELIORATE IL-1BETA-INDUCED DOWNREGULATION OF COLLAGEN II AND THE PRODUCTION OF MMP-13. ALISOL A AND EMODIN COULD EFFECTIVELY MITIGATE CARTILAGE DAMAGE. AT LAST, MOLECULAR DYNAMICS SIMULATIONS WITH MM-GBSA METHOD WAS APPLIED TO INVESTIGATE THE INTERACTION PATTERN OF THE ACTIVE CONSTITUENTS AND DNMT1 COMPLEXES. THE FIVE CONSTITUENTS, SUCH AS ALISOL A, EMODIN, TAXIFOLIN, ISOLIQUIRITIGENIN, AND SCHISANDRIN C ACHIEVED A STABLE BINDING PATTERN WITH DNMT1, IN WHICH ALISOL A HAS A RELATIVELY HIGH BINDING FREE ENERGY. IN CONCLUSION, THIS STUDY ELUCIDATES THAT THE ACTIVE CONSTITUENTS OF DD (ALISOL A, EMODIN, TAXIFOLIN, ISOLIQUIRITIGENIN, AND SCHISANDRIN C) COULD AMELIORATE OSTEOARTHRITIS VIA PPARGAMMA PRESERVATION BY TARGETING DNMT1.THESE FINDINGS FACILITATED CLINICAL USE OF DD AND PROVIDED A VALUABLE STRATEGY FOR DEVELOPING NATURAL EPIGENETIC MODULATORS FROM CHINESE HERBAL FORMULA.	2022	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                    
6  238  31 ADENOSINE KINASE: A KEY REGULATOR OF PURINERGIC PHYSIOLOGY. ADENOSINE (ADO) IS AN ESSENTIAL BIOMOLECULE FOR LIFE THAT PROVIDES CRITICAL REGULATION OF ENERGY UTILIZATION AND HOMEOSTASIS. ADENOSINE KINASE (ADK) IS AN EVOLUTIONARY ANCIENT RIBOKINASE DERIVED FROM BACTERIAL SUGAR KINASES THAT IS WIDELY EXPRESSED IN ALL FORMS OF LIFE, TISSUES AND ORGAN SYSTEMS THAT TIGHTLY REGULATES INTRACELLULAR AND EXTRACELLULAR ADO CONCENTRATIONS. THE FACILE ABILITY OF ADK TO ALTER ADO AVAILABILITY PROVIDES A "SITE AND EVENT" SPECIFICITY TO THE ENDOGENOUS PROTECTIVE EFFECTS OF ADO IN SITUATIONS OF CELLULAR STRESS. IN ADDITION TO MODULATING THE ABILITY OF ADO TO ACTIVATE ITS COGNATE RECEPTORS (P1 RECEPTORS), NUCLEAR ADK ISOFORM ACTIVITY HAS BEEN LINKED TO EPIGENETIC MECHANISMS BASED ON TRANSMETHYLATION PATHWAYS. PREVIOUS DRUG DISCOVERY RESEARCH HAS TARGETED ADK INHIBITION AS A THERAPEUTIC APPROACH TO MANAGE EPILEPSY, PAIN, AND INFLAMMATION. THESE EFFORTS GENERATED MULTIPLE CLASSES OF HIGHLY POTENT AND SELECTIVE INHIBITORS. HOWEVER, CLINICAL DEVELOPMENT OF EARLY ADK INHIBITORS WAS STOPPED DUE TO APPARENT MECHANISTIC TOXICITY AND THE LACK OF SUITABLE TRANSLATIONAL MARKERS. NEW INSIGHTS REGARDING THE POTENTIAL ROLE OF THE NUCLEAR ADK ISOFORM (ADK-LONG) IN THE EPIGENETIC MODULATION OF MALADAPTIVE DNA METHYLATION OFFERS THE POSSIBILITY OF IDENTIFYING NOVEL ADK-ISOFORM SELECTIVE INHIBITORS AND NEW INTERVENTIONAL STRATEGIES THAT ARE INDEPENDENT OF ADO RECEPTOR ACTIVATION.	2021	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                              
7 5511  26 RIBONUCLEASES IN TUMOR GROWTH. THIS REVIEW SUMMARIZES DATA ON AMBIGUOUS BIOLOGICAL FUNCTIONS OF RIBONUCLEASES (RNASES) AT TUMOR GROWTH. IN SOME CASES THE RAISED LEVEL OF ENZYME ACTIVITY IN BIOLOGICAL FLUIDS CAN BE REGARDED AS AN ADDITIONAL MARKER OF MALIGNANT GROWTH (PANCREAS CANCER, CHRONIC MYELOID LEUKEMIA, ETC.). AT THE SAME TIME THE ACTIVITY OF RNASES IS OFTEN LOWERED IN TUMOR TISSUE. HIGH SUBSTRATE SPECIFICITY OF PARTICULAR RNASES PROVIDES METABOLIC BALANCE BETWEEN VARIOUS KINDS OF RNAS WITH VARIOUS HALF-TIME EXCHANGE TURN. RNASES ARE THE IMPORTANT FACTORS OF EPIGENETIC REGULATION OF GENE ACTIVITY IN CELLS. THE ACTIVITY OF RNASES IS ADJUSTABLE BY INHIBITORS AND OTHER FACTORS, AND DEFINES TIME OF EXISTENCE OF DIFFERENT KINDS OF RNAS. RNASES (THE MODIFIED VARIANTS OF RNASE A, RNASES OF SEMEN FLUID OF THE CATTLE, RNASE OF AMPHIBIA OOCYTES) CAN BE USED AS ANTI-TUMOR THERAPEUTIC AGENTS. ON THE OTHER HAND, SOME INHIBITORS OF RNASES OF NATURAL OR SYNTHETIC ORIGIN WERE DEMONSTRATED TO BE PERSPECTIVE DRUGS THAT INHIBIT TUMOR GROWTH.	2009	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                      
8 1679  32 DRUG RESISTANCE IN GIARDIA DUODENALIS. GIARDIA DUODENALIS IS A MICROAEROPHILIC PARASITE OF THE HUMAN GASTROINTESTINAL TRACT AND A MAJOR CONTRIBUTOR TO DIARRHEAL AND POST-INFECTIOUS CHRONIC GASTROINTESTINAL DISEASE WORLD-WIDE. TREATMENT OF G. DUODENALIS INFECTION CURRENTLY RELIES ON A SMALL NUMBER OF DRUG CLASSES. NITROHETEROCYCLICS, IN PARTICULAR METRONIDAZOLE, HAVE REPRESENTED THE FRONT LINE TREATMENT FOR THE LAST 40 YEARS. NITROHETEROCYCLIC-RESISTANT G. DUODENALIS HAVE BEEN ISOLATED FROM PATIENTS AND CREATED IN VITRO, PROMPTING CONSIDERABLE RESEARCH INTO THE BIOMOLECULAR MECHANISMS OF RESISTANCE. THESE COMPOUNDS ARE REDOX-ACTIVE AND ARE BELIEVED TO DAMAGE PROTEINS AND DNA AFTER BEING ACTIVATED BY OXIDOREDUCTASE ENZYMES IN METABOLICALLY ACTIVE CELLS. IN THIS REVIEW, WE EXPLORE THE MOLECULAR PHENOTYPES OF NITROHETEROCYCLIC-RESISTANT G. DUODENALIS DESCRIBED TO DATE IN THE CONTEXT OF THE PROTIST'S UNUSUAL GLYCOLYTIC AND ANTIOXIDANT SYSTEMS. WE PROPOSE THAT RESISTANCE MECHANISMS ARE LIKELY TO EXTEND WELL BEYOND CURRENTLY DESCRIBED RESISTANCE-ASSOCIATED ENZYMES (I.E., PYRUVATE FERREDOXIN OXIDOREDUCTASES AND NITROREDUCTASES), TO INCLUDE NAD(P)H- AND FLAVIN-GENERATING PATHWAYS, AND POSSIBLY REDOX-SENSITIVE EPIGENETIC REGULATION. MECHANISMS THAT ALLOW G. DUODENALIS TO TOLERATE OXIDATIVE STRESS MAY LEAD TO RESISTANCE AGAINST BOTH OXYGEN AND NITROHETEROCYCLICS, WITH IMPLICATIONS FOR CLINICAL CONTROL.

BACKGROUND: X-LINKED MAGT1 DEFICIENCY WITH INCREASED SUSCEPTIBILITY TO EPSTEIN-BARR VIRUS INFECTION AND N-LINKED GLYCOSYLATION DEFECT (XMEN) DISEASE IS A RARE COMBINED IMMUNODEFICIENCY CAUSED BY LOSS-OF-FUNCTION MUTATIONS IN THE MAGNESIUM TRANSPORTER 1 (MAGT1) GENE. MAGT1 DEFICIENCY IMPAIRS MAGNESIUM TRANSPORT AND THE N-LINKED GLYCOSYLATION OF A PANEL OF PROTEINS, WHICH SUBSEQUENTLY ABOLISHES THE EXPRESSION OF KEY IMMUNE RECEPTORS SUCH AS NATURAL KILLER GROUP 2, MEMBER D (AKA NKG2D). THESE EFFECTS INDUCE IMMUNE SYSTEM ABNORMALITIES, CHRONIC EPSTEIN-BARR VIRUS INFECTION, AND NEOPLASIA. RECENT RESEARCH SHOWS THAT MAGT1 AND TUMOR CANDIDATE SUPPRESSOR 3 (TUSC3) SHARE HIGH SEQUENCE AND FUNCTIONAL SIMILARITY. OBJECTIVE: WE SOUGHT TO INVESTIGATE THE FEASIBILITY OF ACTIVATING TUSC3 EXPRESSION TO PROVIDE A POTENTIAL THERAPEUTIC STRATEGY FOR XMEN DISEASE. METHODS: THE EXPRESSION PROFILES OF MAGT1 AND TUSC3 WERE ANALYZED USING MULTIPLE DATABASES, REAL-TIME QUANTITATIVE PCR, AND WESTERN BLOT. THE EFFECTS OF DECITABINE AND PANOBINOSTAT ON THE REGULATION OF TUSC3 EXPRESSION WERE EXPLORED IN BOTH MAGT1 KNOCKOUT (KO)/PATIENT-DERIVED LYMPHOCYTES AND MAGT1 KO HEPATOCYTES. RESULTS: ALTHOUGH TUSC3 IS WIDELY EXPRESSED, IT IS UNDETECTABLE SPECIFICALLY IN THE IMMUNE SYSTEM AND LIVER, CONSISTENT WITH THE MAIN DISEASED TISSUES IN PATIENTS WITH XMEN DISEASE. CRISPR/CAS9-MEDIATED KO OF MAGT1 IN THE NKL CELL LINE SUCCESSFULLY MIMICKED THE PHENOTYPES OF XMEN PATIENT-DERIVED LYMPHOCYTES, AND EXOGENOUS EXPRESSION OF TUSC3 RESCUED THE DEFICIENCIES IN KO NKL CELLS. USING THIS IN VITRO MODEL, WE IDENTIFIED 2 EPIGENETIC DRUGS, DECITABINE AND PANOBINOSTAT, BY SCREENING. COMBINATION TREATMENT USING THESE 2 DRUGS SIGNIFICANTLY UPREGULATED TUSC3 EXPRESSION AND RESCUED THE IMMUNE AND LIVER ABNORMALITIES. CONCLUSIONS: EPIGENETIC ACTIVATION OF TUSC3 EXPRESSION CONSTITUTES AN EFFECTIVE THERAPEUTIC STRATEGY FOR XMEN DISEASE.	2023	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                               
10 1016  37 CIITA EXPRESSION IS REGULATED BY HISTONE DEACETYLASE ENZYMES AND HAS A ROLE IN ALPHA-SYNUCLEIN PRE-FORMED FIBRIL-INDUCED ANTIGEN PRESENTATION IN MURINE MICROGLIAL CELL LINE. AIM: PARKINSON'S DISEASE (PD) IS A CHRONIC NEURODEGENERATIVE DISORDER RELATED WITH SEVERAL GENETIC AND EPIGENETIC FACTORS. IN THE CONTEXT OF EPIGENETIC FACTORS, HISTONE ACETYLATION IS ONE OF THE MOST ASSOCIATED MECHANISMS WITH PARKINSON'S DISEASE PROGRESSION. THIS STUDY INVESTIGATES THE EFFECTS OF THE INCREASED HISTONE ACETYLATION ON ANTIGEN PRESENTATION IN MICROGLIAL CELLS WHICH WERE INDUCED BY PRE-FORMED FIBRILS OF ALPHA-SYNUCLEIN (PFF ALPHA-SYNUCLEIN). METHODS: PARKINSON'S DISEASE MODEL WAS CREATED WITH PFF ALPHA-SYNUCLEIN ADMINISTRATION TO THE BV-2 MICROGLIAL CELLS. BV-2 CELLS WERE CO-TREATED WITH CUDC-907 AND TMP-195 TO INCREASE HISTONE ACETYLATION IN THE PRESENCE OF ALPHA-SYNUCLEIN. ANTIGEN REPRESENTATION WAS EVALUATED BY DETERMINING EXPRESSION LEVELS OF MAJOR HISTOCOMPATIBILITY COMPLEX-II (MHC-II) AND CLASS-II MAJOR HISTOCOMPATIBILITY COMPLEX (CIITA). RESULTS: OUR RESULTS SHOWED THAT PFF ALPHA-SYNUCLEIN SIGNIFICANTLY INCREASED MHC-II EXPRESSION, AND THAT EFFECT WAS MOST SEVERE AT 6 H OF ADMINISTRATION OF ALPHA-SYNUCLEIN. INCREASING HISTONE ACETYLATION VIA CUDC-907 AND TMP-195 ENHANCED MHC-II LEVELS EXPRESSION, WHICH WAS MORE SEVERE IN CUDC-907. ADDITIONALLY, CIITA EXPRESSION LEVELS WERE SIGNIFICANTLY INCREASED WITH PFF ALPHA-SYNUCLEIN ADMINISTRATION AND INTENSIFIED WITH THE CO-TREATMENT OF CUDC-907 AND TMP-195. FURTHERMORE, PFF ALPHA-SYNUCLEIN CAUSED A TIME-DEPENDENT INCREASE IN THE IFN-GAMMA (IFN-?) AND INTERLEUKIN-16(IL-16) LEVELS, AND THAT INCREASE WAS POTENTIATED WITH CUDC-907 AND TMP-195. CONCLUSION: CHANGES IN MHC-II AND CIITA EXPRESSION INDICATE THAT HISTONE ACETYLATION INCREASES THE ANTIGEN PRESENTATION PROPERTIES OF MICROGLIAL CELLS AFTER PFF ALPHA-SYNUCLEIN OR HISTONE DEACETYLASE INHIBITOR (HDACI) ADMINISTRATION. OUR RESULTS SHOW THAT MICROGLIAL ANTIGEN PRESENTATION MIGHT HAVE AN ESSENTIAL ROLE IN THE PATHOLOGY OF PARKINSON'S DISEASE, AND ALPHA-SYNUCLEIN LIKELY TO PLAY A PRIMARY ROLE IN THIS MECHANISM.	2022	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                           
11 2733  44 EXPLORING THE POTENTIAL OF PHYTOCOMPOUNDS FOR TARGETING EPIGENETIC MECHANISMS IN RHEUMATOID ARTHRITIS: AN IN SILICO STUDY USING SIMILARITY INDEXING. FINDING STRUCTURALLY SIMILAR COMPOUNDS IN COMPOUND DATABASES IS HIGHLY EFFICIENT AND IS WIDELY USED IN PRESENT-DAY DRUG DISCOVERY METHODOLOGY. THE MOST-TRUSTED AND -FOLLOWED SIMILARITY INDEXING METHOD IS TANIMOTO SIMILARITY INDEXING. EPIGENETIC PROTEINS LIKE HISTONE DEACETYLASES (HDACS) INHIBITORS ARE TRADITIONALLY USED TO TARGET CANCER, BUT HAVE ONLY BEEN INVESTIGATED VERY RECENTLY FOR THEIR POSSIBLE EFFECTIVENESS AGAINST RHEUMATOID ARTHRITIS (RA). THE SYNTHETIC DRUGS THAT HAVE BEEN IDENTIFIED AND USED FOR THE INHIBITION OF HDACS INCLUDE SAHA, WHICH IS BEING USED TO INHIBIT THE ACTIVITY OF HDACS OF DIFFERENT CLASSES. SAHA WAS CHOSEN AS A COMPOUND OF HIGH IMPORTANCE AS IT IS REPORTED TO INHIBIT THE ACTIVITY OF MANY HDAC TYPES. SIMILARITY SEARCHING USING THE UNPD DATABASE AS A REFERENCE IDENTIFIED AGLAITHIODULINE FROM THE AGLAIA LEPTANTHA COMPOUND AS HAVING A ~70% SIMILARITY OF MOLECULAR FINGERPRINTS WITH SAHA, BASED ON THE TANIMOTO INDEXING METHOD USING CHEMMINER. AGLAITHIODULINE IS ABUNDANTLY PRESENT IN THE SHELL AND FRUITS OF A. LEPTANTHA. IN SILICO STUDIES WITH AGLAITHIODULINE WERE CARRIED OUT AGAINST THE HDAC8 PROTEIN TARGET AND SHOWED A BINDING AFFINITY OF -8.5 KCAL MOL. THE COMPLEX WAS FURTHER SUBJECTED TO MOLECULAR DYNAMICS SIMULATION USING GROMACS. THE RMSD, RMSF, COMPACTNESS AND SASA PLOTS OF THE TARGET WITH AGLAITHIODULINE, IN COMPARISON WITH THE CO-CRYSTALLIZED LIGAND (SAHA) SYSTEM, SHOWED A VERY STABLE CONFIGURATION. THE RESULTS OF THE STUDY ARE SUPPORTIVE OF THE USAGE OF A. LEPTANTHA AND A. EDULIS IN INDIAN TRADITIONAL MEDICINE FOR THE TREATMENT OF PAIN-RELATED AILMENTS SIMILAR TO RA. OUR STUDY THEREFORE CALLS FOR FURTHER INVESTIGATION OF A. LEPTANTHA AND A. EDULIS FOR THEIR POTENTIAL USE AGAINST RA BY TARGETING EPIGENETIC CHANGES, USING IN VIVO AND IN VITRO STUDIES.	2023	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                  
12 1791  24 EFFECT OF CHRONIC RADIATION ON THE FLAX (LINUM USITATISSIMUM L.) GENOME GROWN FOR SIX CONSECUTIVE GENERATIONS IN THE RADIOACTIVE CHERNOBYL AREA. THE GROWTH OF PLANTS UNDER CHRONIC RADIATION STRESS IN THE CHERNOBYL AREA MAY CAUSE CHANGES IN THE GENOME OF PLANTS. TO ASSESS THE EXTENT OF GENETIC AND EPIGENETIC CHANGES IN NUCLEAR DNA, SEEDS OF THE ANNUAL CROP FLAX (LINUM USITATISSIMUM L.) OF THE KYIVSKYI VARIETY, SOWN 21 YEARS AFTER THE ACCIDENT AND GROWN FOR SIX GENERATIONS IN RADIOACTIVE (RAD) AND REMEDIATED (REM) FIELDS WERE ANALYSED. FLAXSEED USED FOR SOWING FIRST GENERATION, WHICH SERVED AS A REFERENCE (REF), WAS ALSO ANALYSED. THE AFLP (AMPLIFIED FRAGMENT LENGTH POLYMORPHISM) REVEALED A HIGHER NUMBER OF SPECIFIC ECORI-MSEI LOCI (3.4-FOLD) IN POOLED FLAXSEED SAMPLES HARVESTED FROM THE RAD FIELD COMPARED WITH THE REM FIELD, INDICATING A LINK BETWEEN THE MUTATION PROCESS IN THE FLAX GENOME AND THE ONGOING ADAPTATION PROCESS. MSAP (METHYLATION-SENSITIVE AMPLIFIED POLYMORPHISM) DETECTING ECORI-MSPI AND ECORI-HPAII LOCI IN FLAX NUCLEAR DNA GENOME SHOWED NO SIGNIFICANT DIFFERENCES IN METHYLATION LEVEL, REACHING ABOUT 33% IN EACH OF THE GROUPS STUDIED. ON THE OTHER HAND, SIGNIFICANT CHANGES IN THE DNA METHYLATION PATTERN OF FLAXSEED SAMPLES HARVESTED FROM THE RAD FIELD COMPARED WITH CONTROLS WERE DETECTED. PAIRWISE F(ST) COMPARISON REVEALED WITHIN BOTH, ECORI-MSPI AND TRANSFORMED METHYLATION-SENSITIVE DATA SETS MORE THAN A 3-FOLD INCREASE OF GENETIC DIVERGENCE IN THE RAD FIELD COMPARED WITH BOTH CONTROLS. THESE RESULTS INDICATE THAT THE NUCLEAR GENOME OF FLAX EXPOSED TO CHRONIC RADIATION FOR SIX GENERATIONS HAS MORE MUTATIONS AND USES DNA METHYLATION AS ONE OF THE ADAPTATION MECHANISMS FOR SUSTAINABILITY UNDER ADVERSE CONDITIONS.	2022	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                
13 5340  32 QUORUM SENSING AND VIRULENCE OF PSEUDOMONAS AERUGINOSA DURING LUNG INFECTION OF CYSTIC FIBROSIS PATIENTS. PSEUDOMONAS AERUGINOSA IS THE PREDOMINANT MICROORGANISM IN CHRONIC LUNG INFECTION OF CYSTIC FIBROSIS PATIENTS. THE CHRONIC LUNG INFECTION IS PRECEDED BY INTERMITTENT COLONIZATION. WHEN THE CHRONIC INFECTION BECOMES ESTABLISHED, IT IS WELL ACCEPTED THAT THE ISOLATED STRAINS DIFFER PHENOTYPICALLY FROM THE INTERMITTENT STRAINS. DOMINATING CHANGES ARE THE SWITCH TO MUCOIDITY (ALGINATE OVERPRODUCTION) AND LOSS OF EPIGENETIC REGULATION OF VIRULENCE SUCH AS THE QUORUM SENSING (QS). TO ELUCIDATE THE DYNAMICS OF P. AERUGINOSA QS SYSTEMS DURING LONG TERM INFECTION OF THE CF LUNG, WE HAVE INVESTIGATED 238 ISOLATES OBTAINED FROM 152 CF PATIENTS AT DIFFERENT STAGES OF INFECTION RANGING FROM INTERMITTENT TO LATE CHRONIC. ISOLATES WERE CHARACTERIZED WITH REGARD TO QS SIGNAL MOLECULES, ALGINATE, RHAMNOLIPID AND ELASTASE PRODUCTION AND MUTANT FREQUENCY. THE GENETIC BASIS FOR CHANGE IN QS REGULATION WERE INVESTIGATED AND IDENTIFIED BY SEQUENCE ANALYSIS OF LASR, RHLR, LASI AND RHLI. THE FIRST QS SYSTEM TO BE LOST WAS THE ONE ENCODED BY LAS SYSTEM 12 YEARS (MEDIAN VALUE) AFTER THE ONSET OF THE LUNG INFECTION WITH SUBSEQUENT LOSS OF THE RHL ENCODED SYSTEM AFTER 17 YEARS (MEDIAN VALUE) SHOWN AS DEFICIENCIES IN PRODUCTION OF THE 3-OXO-C12-HSL AND C4-HSL QS SIGNAL MOLECULES RESPECTIVELY. THE CONCOMITANT DEVELOPMENT OF QS MALFUNCTION SIGNIFICANTLY CORRELATED WITH THE REDUCED PRODUCTION OF RHAMNOLIPIDS AND ELASTASE AND WITH THE OCCURRENCE OF MUTATIONS IN THE REGULATORY GENES LASR AND RHLR. ACCUMULATION OF MUTATIONS IN BOTH LASR AND RHLR CORRELATED WITH DEVELOPMENT OF HYPERMUTABILITY. INTERESTINGLY, A HIGHER NUMBER OF MUCOID ISOLATES WERE FOUND TO PRODUCE C4-HSL SIGNAL MOLECULES AND RHAMNOLIPIDS COMPARED TO THE NON-MUCOID ISOLATES. AS SEEN FROM THE PRESENT DATA, WE CAN CONCLUDE THAT P. AERUGINOSA AND PARTICULARLY THE MUCOID STRAINS DO NOT LOSE THE QS REGULATION OR THE ABILITY TO PRODUCE RHAMNOLIPIDS UNTIL THE LATE STAGE OF THE CHRONIC INFECTION.	2010	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                               
14  760  26 CASZ1: CURRENT IMPLICATIONS IN CARDIOVASCULAR DISEASES AND CANCERS. CASTOR ZINC FINGER 1 (CASZ1) IS A C2H2 ZINC FINGER FAMILY PROTEIN THAT HAS TWO SPLICING VARIANTS, CASZ1A AND CASZ1B. IT IS INVOLVED IN MULTIPLE PHYSIOLOGICAL PROCESSES, SUCH AS TISSUE DIFFERENTIATION AND ALDOSTERONE ANTAGONISM. GENETIC AND EPIGENETIC ALTERNATIONS OF CASZ1 HAVE BEEN CHARACTERIZED IN MULTIPLE CARDIOVASCULAR DISORDERS, SUCH AS CONGENITAL HEART DISEASES, CHRONIC VENOUS DISEASES, AND HYPERTENSION. HOWEVER, LITTLE IS KNOWN ABOUT HOW CASZ1 MECHANICALLY PARTICIPATES IN THE PATHOGENESIS OF THESE DISEASES. OVER THE PAST DECADES, AT FIRST GLANCE, PARADOXICAL INFLUENCES ON CELL BEHAVIORS AND PROGRESSIONS OF DIFFERENT CANCER TYPES HAVE BEEN DISCOVERED FOR CASZ1, WHICH MAY BE EXPLAINED BY A "DOUBLE-AGENT" ROLE FOR CASZ1. IN THIS REVIEW, WE DISCUSS THE PHYSIOLOGICAL FUNCTION OF CASZ1, AND FOCUS ON THE ASSOCIATION OF CASZ1 ABERRATIONS WITH THE PATHOGENESIS OF CARDIOVASCULAR DISEASES AND CANCERS.	2023	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                        
15 3626  29 IN-SILICO DISCOVERY OF DUAL ACTIVE MOLECULE TO RESTORE SYNAPTIC WIRING AGAINST AUTISM SPECTRUM DISORDER VIA HDAC2 AND H3R INHIBITION. METAL-DEPENDENT HISTONE DEACETYLASES (HDACS) ARE ESSENTIAL EPIGENETIC REGULATORS; THEIR MOLECULAR AND PHARMACOLOGICAL ROLES IN MEDICALLY CRITICAL DISEASES SUCH AS NEUROPSYCHIATRIC DISORDERS, NEURODEGENERATION, AND CANCER ARE BEING STUDIED GLOBALLY. HDAC2'S DIFFERENTIAL EXPRESSION IN THE CENTRAL NERVOUS SYSTEM MAKES IT AN APPEALING THERAPEUTIC TARGET FOR CHRONIC NEUROLOGICAL DISEASES LIKE AUTISM SPECTRUM DISORDER. IN THIS STUDY, WE IDENTIFIED H3R INHIBITOR MOLECULES THAT ARE COMPUTATIONALLY EFFECTIVE AT BINDING TO THE HDAC2 METAL-COORDINATED BINDING SITE. THE STUDY HIGHLIGHTS THE IMPORTANCE OF PITOLISANT IN SCREENING THE POTENTIAL H3R INHIBITORS BY USING A HYBRID WORKFLOW OF LIGAND AND RECEPTOR-BASED DRUG DISCOVERY.

16 2640  25 EPIGENOMIC AND TRANSCRIPTIONAL PROFILING IDENTIFIES IMPAIRED GLYOXYLATE DETOXIFICATION IN NAFLD AS A RISK FACTOR FOR HYPEROXALURIA. EPIGENETIC MODIFICATIONS (E.G. DNA METHYLATION) IN NAFLD AND THEIR CONTRIBUTION TO DISEASE PROGRESSION AND EXTRAHEPATIC COMPLICATIONS ARE POORLY EXPLORED. HERE, WE USE AN INTEGRATED EPIGENOME AND TRANSCRIPTOME ANALYSIS OF MOUSE NAFLD HEPATOCYTES AND IDENTIFY ALTERATIONS IN GLYOXYLATE METABOLISM, A PATHWAY RELEVANT IN KIDNEY DAMAGE VIA OXALATE RELEASE-A HARMFUL WASTE PRODUCT AND KIDNEY STONE-PROMOTING FACTOR. DOWNREGULATION AND HYPERMETHYLATION OF ALANINE-GLYOXYLATE AMINOTRANSFERASE (AGXT), WHICH DETOXIFIES GLYOXYLATE, PREVENTING EXCESSIVE OXALATE ACCUMULATION, IS ACCOMPANIED BY INCREASED OXALATE FORMATION AFTER METABOLISM OF THE PRECURSOR HYDROXYPROLINE. VIRAL-MEDIATED AGXT TRANSFER OR INHIBITING HYDROXYPROLINE CATABOLISM RESCUES EXCESSIVE OXALATE RELEASE. IN HUMAN STEATOTIC HEPATOCYTES, AGXT IS ALSO DOWNREGULATED AND HYPERMETHYLATED, AND IN NAFLD ADOLESCENTS, STEATOSIS SEVERITY CORRELATES WITH URINARY OXALATE EXCRETION. THUS, THIS WORK IDENTIFIES A REDUCED CAPACITY OF THE STEATOTIC LIVER TO DETOXIFY GLYOXYLATE, TRIGGERING ELEVATED OXALATE, AND PROVIDES A MECHANISTIC EXPLANATION FOR THE INCREASED RISK OF KIDNEY STONES AND CHRONIC KIDNEY DISEASE IN NAFLD PATIENTS.	2021	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                        
17  681  32 BRAIN LIPOTOXICITY OF PHYTANIC ACID AND VERY LONG-CHAIN FATTY ACIDS. HARMFUL CELLULAR/MITOCHONDRIAL ACTIVITIES IN REFSUM DISEASE AND X-LINKED ADRENOLEUKODYSTROPHY. IT IS INCREASINGLY UNDERSTOOD THAT IN THE AGING BRAIN, ESPECIALLY IN THE CASE OF PATIENTS SUFFERING FROM NEURODEGENERATIVE DISEASES, SOME FATTY ACIDS AT PATHOLOGICALLY HIGH CONCENTRATIONS EXERT DETRIMENTAL ACTIVITIES. TO STUDY SUCH ACTIVITIES, WE HERE ANALYZE GENETIC DISEASES, WHICH ARE DUE TO COMPROMISED METABOLISM OF SPECIFIC FATTY ACIDS, EITHER THE BRANCHED-CHAIN PHYTANIC ACID OR VERY LONG-CHAIN FATTY ACIDS (VLCFAS). MICROMOLAR CONCENTRATIONS OF PHYTANIC ACID OR OF VLCFAS DISTURB THE INTEGRITY OF NEURAL CELLS BY IMPAIRING CA(2+) HOMEOSTASIS, ENHANCING OXIDATIVE STRESS OR DE-ENERGIZING MITOCHONDRIA. FINALLY, THESE COMBINED HARMFUL ACTIVITIES ACCELERATE CELL DEATH. MITOCHONDRIA ARE MORE SEVERELY TARGETED BY PHYTANIC ACID THAN BY VLCFAS. THE INSERTION OF VLCFAS INTO THE INNER MEMBRANE DISTORTS THE ARRANGEMENT OF MEMBRANE CONSTITUENTS AND THEIR FUNCTIONAL INTERACTIONS. PHYTANIC ACID EXERTS SPECIFIC PROTONOPHORIC ACTIVITY, INDUCES REACTIVE OXYGEN SPECIES (ROS) GENERATION, AND REDUCES ATP GENERATION. A CLEAR INHIBITION OF THE NA(+), K(+)-ATPASE ACTIVITY BY PHYTANIC ACID HAS ALSO BEEN REPORTED. IN ADDITION TO THE INSTANTANEOUS EFFECTS, A CHRONIC EXPOSURE OF BRAIN CELLS TO LOW MICROMOLAR CONCENTRATIONS OF PHYTANIC ACID MAY PRODUCE NEURONAL DAMAGE IN REFSUM DISEASE BY ALTERING EPIGENETIC TRANSCRIPTIONAL REGULATION. MYELIN-PRODUCING OLIGODENDROCYTES RESPOND WITH PARTICULAR SENSITIVITY TO VLCFAS. DELETERIOUS ACTIVITY OF VLCFAS ON ENERGY-DEPENDENT MITOCHONDRIAL FUNCTIONS DECLINES WITH INCREASING THE HYDROCARBON CHAIN LENGTH (C22:0 > C24:0 > C26:0). IN CONTRAST, THE REVERSE SEQUENCE HOLDS TRUE FOR CELL DEATH INDUCTION BY VLCFAS (C22:0 < C24:0 < C26:0). IN ADRENOLEUKODYSTROPHY, THE UPTAKE OF VLCFAS BY PEROXISOMES IS IMPAIRED BY DEFECTS OF THE ABCD1 TRANSPORTER. STUDYING MITOCHONDRIA FROM ABCD1-DEFICIENT AND WILD-TYPE MICE PROVES THAT THE ENERGY-DEPENDENT FUNCTIONS ARE NOT ALTERED IN THE DISEASE MODEL. THUS, A DEFECTIVE ABCD1 APPARENTLY EXERTS NO OBVIOUS ADAPTIVE PRESSURE ON MITOCHONDRIA. FURTHER RESEARCH HAS TO ELUCIDATE THE DETAILED MECHANISTIC BASIS FOR THE FAILURES CAUSING FATTY ACID-MEDIATED NEURODEGENERATION AND SHOULD HELP TO PROVIDE POSSIBLE THERAPEUTIC INTERVENTIONS.	2016	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                           
18 5353  36 RE-EVALUATION OF POLIHEXANIDE USE IN WOUND ANTISEPSIS IN ORDER TO CLARIFY AMBIGUITIES OF TWO ANIMAL STUDIES. OBJECTIVE: DUE TO CLASSIFICATION OF THE AGENT POLIHEXANIDE (PHMB) IN CATEGORY 2 'MAY CAUSE CANCER' BY THE COMMITTEE FOR RISK ASSESSMENT OF THE EUROPEAN CHEMICALS AGENCY IN 2011, THE USERS OF WOUND ANTISEPTICS MAY BE HIGHLY CONFUSED. IN 2017, THIS STATEMENT WAS UPDATED, DEFINING PHMB UP TO 0.1% AS A PRESERVATIVE SAFE IN ALL COSMETIC PRODUCTS. IN THE INTEREST OF PATIENT SAFETY, A SCIENTIFIC CLARIFICATION OF THE POTENTIAL CARCINOGENICITY OF PHMB IS NECESSARY. METHODS: A MULTIDISCIPLINARY TEAM (MDT) OF MICROBIOLOGISTS, SURGEONS, DERMATOLOGISTS AND BIOCHEMISTS CONDUCTED A BENEFIT-RISK ASSESSMENT TO CLARIFY THE HAZARD OF ANTISEPTIC USE OF PHMB. RESULTS: IN TWO ANIMAL STUDIES, FROM WHICH THE ASSESSMENT OF A CARCINOGENIC RISK WAS DERIVED, PHMB WAS ADMINISTERED ORALLY OVER TWO YEARS IN EXTREMELY HIGH CONCENTRATIONS FAR ABOVE THE NO(A)EL (NO-OBSERVED-(ADVERSE-) EFFECT LEVEL) IN RATS AND MICE. FEEDING IN THE NO(A)EL RANGE RESULTED IN NO ABNORMAL EFFECTS. IN ONE MALE IN THE HIGHEST DOSE GROUP OF 4000PPM PHMB, AN ADENOCARCINOMA WAS FOUND, WHICH THE AUTHOR ATTRIBUTED TO CHRONIC INFLAMMATION OF THE COLON WITH SYSTEMIC ATYPICAL EXPOSURE. THE INCREASING INCIDENCE OF HEMANGIOSARCOMAS HIGHLY PROBABLY RESULTED FROM INCREASED ENDOTHELIAL PROLIFERATION, TRIGGERED BY THE EXCEEDINGLY HIGH DOSAGE FED, BECAUSE PHMB IS NOT GENOTOXIC AND THERE IS NO EVIDENCE FOR EPIGENETIC EFFECTS. DISCUSSION: IT IS WELL KNOWN THAT PHMB IS NOT ABSORBED WHEN APPLIED TOPICALLY. CONSIDERING THE ABSENCE OF GENOTOXICITY AND EPIGENETIC EFFECTS TOGETHER WITH THE INTERPRETATION OF THE ANIMAL STUDIES, IT IS THE CONSENSUS OF THE MULTIDISCIPLINARY EXPERTS THAT A CARCINOGENIC RISK FROM PHMB-USE FOR WOUND ANTISEPSIS CAN BE RULED OUT. CONCLUSION: ON THIS BASIS AND CONSIDERING THEIR EFFECTIVENESS, TOLERABILITY AND CLINICAL EVIDENCE, THE INDICATIONS FOR PHMB BASED WOUND ANTISEPTICS ARE JUSTIFIED.	2019	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                
19  768  23 CD47 (CLUSTER OF DIFFERENTIATION 47). CD47, ALSO KNOWN AS INTEGRIN-ASSOCIATED PROTEIN, IS A CONSTITUTIVELY AND UBIQUITOUSLY EXPRESSED TRANSMEMBRANE RECEPTOR. CD47 IS CONSERVED ACROSS AMNIOTES INCLUDING MAMMALS, REPTILES, AND BIRDS. EXPRESSION IS INCREASED IN MANY CANCERS AND, IN NON-MALIGNANT CELLS, BY STRESS AND WITH AGING. THE UP-REGULATION OF CD47 EXPRESSION IS GENERALLY EPIGENETIC, WHEREAS GENE AMPLIFICATION OCCURS WITH LOW FREQUENCY IN SOME CANCERS. CD47 IS A HIGH AFFINITY SIGNALING RECEPTOR FOR THE SECRETED PROTEIN THROMBOSPONDIN-1 (THBS1) AND THE COUNTER-RECEPTOR FOR SIGNAL REGULATORY PROTEIN-ALPHA (SIRPA, SIRPALPHA) AND SIRPGAMMA (SIRPG). CD47 INTERACTION WITH SIRPALPHA SERVES AS A MARKER OF SELF TO INNATE IMMUNE CELLS AND THEREBY PROTECTS CANCER CELLS FROM PHAGOCYTIC CLEARANCE. CONSEQUENTLY, HIGHER CD47 CORRELATES WITH A POOR PROGNOSIS IN SOME CANCERS, AND THERAPEUTIC BLOCKADE CAN SUPPRESS TUMOR GROWTH BY ENHANCING INNATE ANTITUMOR IMMUNITY. CD47 EXPRESSED ON CYTOTOXIC T CELLS, DENDRITIC CELLS, AND NK CELLS MEDIATES INHIBITORY THBS1 SIGNALING THAT FURTHER LIMITS ANTITUMOR IMMUNITY. CD47 LATERALLY ASSOCIATES WITH SEVERAL INTEGRINS AND THEREBY REGULATES CELL ADHESION AND MIGRATION. CD47 HAS ADDITIONAL LATERAL BINDING PARTNERS IN SPECIFIC CELL TYPES, AND LIGATION OF CD47 IN SOME CASES MODULATES THEIR FUNCTION. THBS1-CD47 SIGNALING IN NON-MALIGNANT CELLS INHIBITS NITRIC OXIDE/CGMP, CALCIUM, AND VEGF SIGNALING, MITOCHONDRIAL HOMEOSTASIS, STEM CELL MAINTENANCE, PROTECTIVE AUTOPHAGY, AND DNA DAMAGE RESPONSE, AND PROMOTES NADPH OXIDASE ACTIVITY. CD47 SIGNALING IS A PHYSIOLOGICAL REGULATOR OF PLATELET ACTIVATION, ANGIOGENESIS AND BLOOD FLOW. THBS1/CD47 SIGNALING IS FREQUENTLY DYSREGULATED IN CHRONIC DISEASES.	2021	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                               
20 5763  20 SOME COMMENTS ON MASOCHISM AND THE DELUSION OF OMNIPOTENCE FROM A DEVELOPMENTAL PERSPECTIVE. THIS PAPER EXPLORES THE RELATION OF THE DELUSION OF OMNIPOTENCE TO MASOCHISM AND SUGGESTS THAT THIS FANTASY CONSTITUTES A MAJOR COMPONENT OF THE RESISTANCE SO PROMINENT IN WORK WITH MASOCHISTIC PATIENTS. THE CONNECTIONS AMONG MASOCHISM, OMNIPOTENCE, NEGATIVE THERAPEUTIC REACTION, AND CLINGING TO PAIN ARE DISCUSSED. THE CLASSICAL VIEW HAS BEEN THAT THE FAILURE OF INFANTILE OMNIPOTENCE FORCES THE CHILD TO TURN TO REALITY. OUR EXPERIENCE WITH MASOCHISTIC PATIENTS SUGGESTS THAT IT IS THE REAL FAILURE TO ACHIEVE COMPETENT INTERACTIONS WITH OTHERS THAT FORCES THE CHILD TO TURN TO OMNIPOTENT SOLUTIONS. THE DISTINCTION IS MADE BETWEEN FANTASIES THAT ENHANCE THE REAL CAPACITIES OF THE SELF AND THOSE AIMED AT DENYING AND TRANSFORMING THE PAIN AND INADEQUACY OF THE MOTHER-CHILD RELATIONSHIP. THE EPIGENETIC TRANSFORMATIONS OF OMNIPOTENT FANTASIES THROUGH ALL LEVELS OF DEVELOPMENT ARE DESCRIBED. THE PATIENT'S NEED TO PROTECT THE OMNIPOTENT FANTASY IS DISCUSSED IN RELATION TO RESISTANCE AT EACH PHASE OF ANALYSIS.	1991
