1  5701 127 SINGLE NUCLEOTIDE POLYMORPHISMS OF CAUDAL TYPE HOMEOBOX 1 AND 2 ARE ASSOCIATED WITH BARRETT'S ESOPHAGUS. BACKGROUND: BARRETT'S ESOPHAGUS (BE), THE PREMALIGNANT LESION OF ESOPHAGEAL ADENOCARCINOMA, IS BELIEVED TO DEVELOP AS A RESULT OF CHRONIC GASTROESOPHAGEAL REFLUX DISEASE (GERD). APPROXIMATELY 10 % OF SUBJECTS WITH GERD PROGRESS TO BE. GENETIC, EPIGENETIC AND OTHER RISK FACTORS MAY CONTRIBUTE TO THIS INTER-INDIVIDUAL VARIABILITY. CAUDAL TYPE HOMEOBOX 1 (CDX1) AND CAUDAL TYPE HOMEOBOX 2 (CDX2) PLAY IMPORTANT REGULATORY ROLES IN THE DEVELOPMENT OF HUMAN BE. AIMS: TO DETERMINE ASSOCIATIONS BETWEEN CDX1 AND CDX2 SINGLE NUCLEOTIDE POLYMORPHISMS (SNPS) AND BE. METHODS: GENOMIC DNA WAS EXTRACTED FROM BLOOD SAMPLES COLLECTED FROM BE (N = 109) AND GERD (N = 223) PATIENTS FOR GENOTYPING OF 5 SNPS EACH OF CDX1 AND CDX2 USING TAQMAN ALLELIC DISCRIMINATION ASSAYS. ODDS RATIOS AND 95 % CONFIDENCE INTERVALS OF SNPS AND HAPLOTYPES WERE CALCULATED WITH A LOGISTIC REGRESSION MODEL ADJUSTED FOR FACTORS INCLUDING AGE, SEX AND HIATAL HERNIA. INTERACTIONS BETWEEN GENETIC VARIANTS AND THESE THREE RISK FACTORS WERE ALSO ANALYZED. RESULTS: OLDER AGE (>/=50 YEARS), MALE SEX AND HIATAL HERNIA WERE SIGNIFICANTLY ASSOCIATED WITH BE (P < 0.001). FIVE VARIANTS OF CDX1 SNPS (RS3776082, RS717746 AND RS3776083), ONE CDX1 HAPLOTYPE, AND THREE VARIANTS OF CDX2 SNPS (RS4769585 AND RS3812863) WERE ASSOCIATED WITH BE (P < 0.05). STATISTICALLY SIGNIFICANT INTERACTIONS WERE DETECTED BETWEEN MOST OF THESE SNPS AND THE THREE RISK FACTORS (P < 0.05). CONCLUSION: CERTAIN SNPS OF CDX1 AND CDX2 AND THEIR INTERACTIONS WITH OTHER RISK FACTORS ARE ASSOCIATED WITH BE, AND MAY CONTRIBUTE TO HUMAN SUSCEPTIBILITY TO BE.	2014	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                 
2  3660  21 INDUCTION OF HEPATIC DIFFERENTIATION OF MOUSE BONE MARROW STROMAL STEM CELLS BY THE HISTONE DEACETYLASE INHIBITOR VPA. BONE MARROW STROMAL STEM CELLS (BMSSCS) MAY HAVE POTENTIAL TO DIFFERENTIATE IN VITRO AND IN VIVO INTO HEPATOCYTES. HERE, WE INVESTIGATED THE EFFECTS OF VALPROIC ACID (VPA) INVOLVED IN EPIGENETIC MODIFICATION, A DIRECT INHIBITOR OF HISTONE DEACETYLASE, ON HEPATIC DIFFERENTIATION OF MOUSE BMSSCS. FOLLOWING THE TREATMENT OF 2.5 MM VPA FOR 72 HRS, THE IN VITRO EXPANDED, HIGHLY PURIFIED AND FUNCTIONALLY ACTIVE MOUSE BMSSCS FROM BONE MARROW WERE EITHER EXPOSED TO SOME WELL-DEFINED CYTOKINES AND GROWTH FACTORS IN A SEQUENTIAL WAY (FIBROBLAST GROWTH FACTOR-4 [FGF-4], FOLLOWED BY HGF, AND HGF + OSM + ITS + DEXAMETHASONE, RESEMBLING THE ORDER OF SECRETION DURING LIVER EMBRYOGENESIS) OR TRANSPLANTED (CAUDAL VEIN) IN MICE SUBMITTED TO A PROTOCOL OF CHRONIC INJURY (CHRONIC I.P. INJECTION OF CCL4). ADDITIONAL EXPOSURE OF THE CELLS TO VPA CONSIDERABLY IMPROVED THE IN VITRO DIFFERENTIATION, AS DEMONSTRATED BY A MORE HOMOGENEOUS CELL POPULATION EXHIBITED EPITHELIAL MORPHOLOGY, INCREASING EXPRESSION OF HEPATIC SPECIAL GENES AND ENHANCED HEPATIC FUNCTIONS. FURTHER MORE, IN VIVO RESULTS INDICATE THAT THE PRE-TREATMENT OF VPA SIGNIFICANTLY INCREASED THE HOMING EFFICIENCY OF BMSSCS TO THE SITE OF LIVER INJURY AND, ADDITIONALLY, FOR SUPPORTING HEPATIC DIFFERENTIATION AS WELL AS IN VITRO. WE HAVE DEMONSTRATED THE USEFULNESS OF VPA IN THE TRANSDIFFERENTIATION OF BMSSCS INTO HEPATOCYTES BOTH IN VITRO AND IN VIVO, AND REGULATION OF FIBROBLAST GROWTH FACTOR RECEPTORS (FGFRS) AND C-MET GENE EXPRESSION THROUGH POST-TRANSLATIONAL MODIFICATION OF CORE HISTONES MIGHT BE THE PRIMARY INITIATING EVENT FOR THESE EFFECTS. THIS MODE COULD BE HELPFUL FOR LIVER ENGINEERING AND CLINICAL THERAPY.	2009	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                         
3  5246  37 PROGNOSTIC SCORE INCLUDING GENE MUTATIONS IN CHRONIC MYELOMONOCYTIC LEUKEMIA. PURPOSE: SEVERAL PROGNOSTIC SCORING SYSTEMS HAVE BEEN PROPOSED FOR CHRONIC MYELOMONOCYTIC LEUKEMIA (CMML), A DISEASE IN WHICH SOME GENE MUTATIONS-INCLUDING ASXL1-HAVE BEEN ASSOCIATED WITH POOR PROGNOSIS IN UNIVARIABLE ANALYSES. WE DEVELOPED AND VALIDATED A PROGNOSTIC SCORE FOR OVERALL SURVIVAL (OS) BASED ON MUTATIONAL STATUS AND STANDARD CLINICAL VARIABLES. PATIENTS AND METHODS: WE GENOTYPED ASXL1 AND UP TO 18 OTHER GENES INCLUDING EPIGENETIC (TET2, EZH2, IDH1, IDH2, DNMT3A), SPLICING (SF3B1, SRSF2, ZRSF2, U2AF1), TRANSCRIPTION (RUNX1, NPM1, TP53), AND SIGNALING (NRAS, KRAS, CBL, JAK2, FLT3) REGULATORS IN 312 PATIENTS WITH CMML. GENOTYPES AND CLINICAL VARIABLES WERE INCLUDED IN A MULTIVARIABLE COX MODEL OF OS VALIDATED BY BOOTSTRAPPING. A SCORING SYSTEM WAS DEVELOPED USING REGRESSION COEFFICIENTS FROM THIS MODEL. RESULTS: ASXL1 MUTATIONS (P < .0001) AND, TO A LESSER EXTENT, SRSF2 (P = .03), CBL (P = .003), AND IDH2 (P = .03) MUTATIONS PREDICTED INFERIOR OS IN UNIVARIABLE ANALYSIS. THE RETAINED INDEPENDENT PROGNOSTIC FACTORS INCLUDED ASXL1 MUTATIONS, AGE OLDER THAN 65 YEARS, WBC COUNT GREATER THAN 15 X10(9)/L, PLATELET COUNT LESS THAN 100 X10(9)/L, AND ANEMIA (HEMOGLOBIN < 10 G/DL IN FEMALE PATIENTS, < 11G/DL IN MALE PATIENTS). THE RESULTING FIVE-PARAMETER PROGNOSTIC SCORE DELINEATED THREE GROUPS OF PATIENTS WITH MEDIAN OS NOT REACHED, 38.5 MONTHS, AND 14.4 MONTHS, RESPECTIVELY (P < .0001), AND WAS VALIDATED IN AN INDEPENDENT COHORT OF 165 PATIENTS (P < .0001). CONCLUSION: A NEW PROGNOSTIC SCORE INCLUDING ASXL1 STATUS, AGE, HEMOGLOBIN, WBC, AND PLATELET COUNTS DEFINES THREE GROUPS OF CMML PATIENTS WITH DISTINCT OUTCOMES. BASED ON CONCORDANCE ANALYSIS, THIS SCORE APPEARS MORE DISCRIMINATIVE THAN THOSE BASED SOLELY ON CLINICAL PARAMETERS.	2013	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                               
4  1953  33 EPIGENETIC AGE ACCELERATION AND CHRONIC HEALTH CONDITIONS AMONG ADULT SURVIVORS OF CHILDHOOD CANCER. BACKGROUND: MOUNTING EVIDENCE SUPPORTS THE OCCURRENCE OF ACCELERATING AGING AMONG LONG-TERM SURVIVORS OF CHILDHOOD CANCER. WE AIMED TO INVESTIGATE EPIGENETIC AGE ACCELERATION (EAA) IN SURVIVORS AND EVALUATE ASSOCIATIONS BETWEEN EAA, TREATMENT EXPOSURES, HEALTH BEHAVIORS, AND CHRONIC HEALTH CONDITIONS (CHCS). METHODS: GENOME-WIDE METHYLATION DATA WERE GENERATED WITH INFINIUM EPIC BEADCHIP ON BLOOD-DERIVED DNA FROM 2139 SURVIVORS AND 282 FREQUENCY MATCHED CONTROLS FROM THE ST JUDE LIFETIME COHORT STUDY. EAAS WERE ESTIMATED AS RESIDUALS FROM A LINEAR REGRESSION OF EPIGENETIC AGE (LEVINE'S CLOCK) AGAINST CHRONOLOGICAL AGE. ADJUSTED LEAST SQUARE MEAN (ALSM) OF EAA WAS CALCULATED AND COMPARED BETWEEN SURVIVORS AND CONTROLS, ACROSS TREATMENT EXPOSURES AND HEALTH BEHAVIORS. ASSOCIATIONS OF EAA WITH 20 CLINICALLY ASSESSED CHCS WERE EVALUATED WITH MULTIVARIABLE PIECEWISE-EXPONENTIAL MODELS. ALL STATISTICAL TESTS FOR P VALUES BELOW WERE 2-SIDED. RESULTS: EAA WAS STATISTICALLY SIGNIFICANTLY HIGHER IN SURVIVORS THAN CONTROLS (ALSM = 0.63, 95% CONFIDENCE INTERVAL [CI] = 0.26 TO 1.01 VS -3.61, 95% CI = -4.43 TO 2.80). IN A MULTIVARIABLE MODEL AMONG SURVIVORS, STATISTICALLY SIGNIFICANTLY HIGHER EAA (P < .05) WAS OBSERVED IN THOSE EXPOSED TO CHEST RADIOTHERAPY, ABDOMEN OR PELVIC RADIOTHERAPY, ALKYLATING AGENTS, GLUCOCORTICOIDS, OR EPIPODOPHYLLOTOXINS. COMPARED WITH SURVIVORS WITH FAVORABLE HEALTH BEHAVIORS (ALSM = 0.26, 95% CI=-0.36 TO 0.87), EAA WAS STATISTICALLY SIGNIFICANTLY HIGHER AMONG SURVIVORS WITH INTERMEDIATE (ALSM = 1.07, 95% CI = 0.59 TO 1.54) OR UNFAVORABLE HEALTH BEHAVIORS (ALSM = 1.45, 95% CI = 0.60 TO 2.30). IN TIME-TO-EVENT ANALYSES, STATISTICALLY SIGNIFICANT ASSOCIATIONS WERE IDENTIFIED BETWEEN EAA TERTILES AND INCIDENCE OF 7 CHCS: HYPERTENSION (3RD VS 1ST TERTILE, RELATIVE RATE [RR] = 1.83, 95% CI = 1.17 TO 2.83), MYOCARDIAL INFARCTION (RR = 2.91, 95% CI = 1.27 TO 7.21), OBESITY (RR = 1.39, 95% CI = 1.17 TO 1.66), OBSTRUCTIVE PULMONARY DEFICIT (RR = 1.86, 95% CI = 0.95 TO 3.77), PERIPHERAL MOTOR NEUROPATHY (RR = 2.89, 95% CI = 1.24 TO 6.97), PERIPHERAL SENSORY NEUROPATHY (RR = 2.04, 95% CI = 0.99 TO 4.26), AND PULMONARY DIFFUSION DEFICITS (RR = 2.75, 95% CI = 0.95 TO 7.63). CONCLUSIONS: EAA IS STATISTICALLY SIGNIFICANTLY HIGHER IN SURVIVORS OF CHILDHOOD CANCER THAN IN NONCANCER CONTROLS AND IS ASSOCIATED WITH SPECIFIC TREATMENT EXPOSURES, UNFAVORABLE HEALTH BEHAVIORS, AND PRESENCE OF SPECIFIC CHCS.	2021	
                                                                                                                                   
5  1797  34 EFFECT OF HELICOBACTER PYLORI ERADICATION ON GASTRIC PRECANCEROUS LESIONS: A SYSTEMATIC REVIEW AND META-ANALYSIS. BACKGROUND: THE QUESTION OF WHETHER ERADICATION OF HELICOBACTER PYLORI (HP) CAN REVERSE GASTRIC PRECANCEROUS LESIONS, INCLUDING INTESTINAL METAPLASIA, REMAINS UNCERTAIN, LEADING TO ONGOING DEBATE. THEREFORE, A META-ANALYSIS WAS PERFORMED TO EVALUATE THE EFFECT OF HP ERADICATION ON GASTRIC PRECANCEROUS LESIONS. MATERIALS AND METHODS: PUBMED, EMBASE, COCHRANE LIBRARY, WEB OF SCIENCE, SCOPUS DATABASE, AND CLINICALTRIALS.GOV WERE SYSTEMATICALLY SEARCHED FROM INCEPTION TO APRIL 2023 FOR STUDIES THAT EXPLORED THE IMPACT OF HP ERADICATION ON GASTRIC PRECANCEROUS LESIONS. RISK RATIOS (RRS) AND THEIR 95% CONFIDENCE INTERVALS (95% CIS) WERE SELECTED AS THE EFFECT SIZE. WE USED THE RANDOM-EFFECTS MODEL TO ASSESS POOLED DATA. WE ALSO PERFORMED QUALITY ASSESSMENTS, SUBGROUP ANALYSES, AND SENSITIVITY ANALYSES. RESULTS: FIFTEEN STUDIES WERE INCLUDED. COMPARED WITH PLACEBO, HP ERADICATION COULD SIGNIFICANTLY PREVENT THE PROGRESSION OF GASTRIC PRECANCEROUS LESIONS (RR = 0.87, 95% CI: 0.81-0.94, P < 0.01) AND REVERSE THEM (RR = 1.32, 95% CI: 1.17-1.50, P < 0.01). THEN, SPECIFIC PRECANCEROUS LESIONS WERE FURTHER EXPLORED. THE PROGRESSION OF INTESTINAL METAPLASIA WAS SIGNIFICANTLY PREVENTED BY HP ERADICATION COMPARED TO PLACEBO OR NO TREATMENT (RR = 0.80, 95% CI: 0.69-0.94, P < 0.01). MOREOVER, COMPARED WITH PLACEBO OR NO TREATMENT, HP ERADICATION ALSO IMPROVED CHRONIC ATROPHIC GASTRITIS (RR = 1.84, 95% CI: 1.30-2.61, P < 0.01) AND INTESTINAL METAPLASIA (RR = 1.41, 95% CI: 1.15-1.73, P < 0.01). HOWEVER, IN TERMS OF PREVENTING DYSPLASIA PROGRESSION (RR = 0.86, 95% CI: 0.37-2.00) AND IMPROVING DYSPLASIA (RR = 0.89, 95% CI: 0.47-1.70), HP ERADICATION HAD NO ADVANTAGE COMPARED TO PLACEBO OR NO TREATMENT. CONCLUSIONS: HP ERADICATION THERAPY COULD PREVENT THE PROGRESSION OF GASTRIC PRECANCEROUS LESIONS AND REVERSE THEM. NOTABLY, INTESTINAL METAPLASIA CAN BE REVERSED, BUT THIS MAY ONLY BE APPROPRIATE FOR PATIENTS WITH EPIGENETIC ALTERATIONS AND MILDER LESIONS.	2023	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                 
6  4913  26 PAIN MODULATION IN WAG/RIJ EPILEPTIC RATS (A GENETIC MODEL OF ABSENCE EPILEPSY): EFFECTS OF BIOLOGICAL AND PHARMACOLOGICAL HISTONE DEACETYLASE INHIBITORS. EPIGENETIC MECHANISMS ARE INVOLVED IN EPILEPSY AND CHRONIC PAIN DEVELOPMENT. ABOUT THAT, WE STUDIED THE EFFECTS OF THE NATURAL HISTONE DEACETYLASE (HDAC) INHIBITOR SODIUM BUTYRATE (BUT) IN COMPARISON WITH VALPROIC ACID (VPA) IN A VALIDATED GENETIC MODEL OF GENERALIZED ABSENCE EPILEPSY AND EPILEPTOGENESIS. WAG/RIJ RATS WERE TREATED WITH BUT (30 MG/KG), VPA (300 MG/KG), AND THEIR COMBINATION (BUT + VPA) DAILY PER OS FOR 6 MONTHS. RATS WERE SUBJECTED AT RANDALL-SELITTO, VON FREY, HOT PLATE, AND TAIL FLICK TESTS AFTER 1, 3, AND 6 MONTHS OF TREATMENT TO EVALUATE HYPERSENSITIVITY TO NOXIOUS AND NON-NOXIUOUS STIMULI. MOREOVER, PPAR-GAMMA (G3335 1 MG/KG), GABA-B (CGP35348 80 MG/KG), AND OPIOID (NALOXONE 1 MG/KG) RECEPTOR ANTAGONISTS WERE ADMINISTRATED TO INVESTIGATE THE POSSIBLE MECHANISMS INVOLVED IN ANALGESIC ACTIVITY. THE EXPRESSION OF NFKB, GLUTATHIONE REDUCTASE, AND PROTEIN OXIDATION (CARBONYLATION) WAS ALSO EVALUATED BY WESTERN BLOT ANALYSIS. WAG/RIJ RATS SHOWED AN ALTERED PAIN THRESHOLD THROUGHOUT THE STUDY (P < 0.001). BUT AND BUT + VPA TREATMENT REDUCED HYPERSENSITIVITY (P < 0.01). VPA WAS SIGNIFICANTLY EFFECTIVE ONLY AFTER 1 MONTH (P < 0.01). ALL THE THREE RECEPTORS ARE INVOLVED IN BUT + VPA EFFECTS (P < 0.001). BUT AND BUT + VPA DECREASED THE EXPRESSION OF NFKB AND ENHANCED GLUTATHIONE REDUCTASE (P < 0.01); PROTEIN OXIDATION (CARBONYLATION) WAS REDUCED (P < 0.01). NO EFFECT WAS REPORTED WITH VPA. IN CONCLUSION BUT, ALONE OR IN COADMINISTRATION WITH VPA, IS A VALUABLE CANDIDATE FOR MANAGING THE EPILEPSY-RELATED PERSISTENT PAIN.	2020	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                    
7  2678  28 EVALUATION OF A PROGNOSTIC EPIGENETIC CLASSIFICATION SYSTEM IN CHRONIC LYMPHOCYTIC LEUKEMIA PATIENTS. BACKGROUND: METHYLATION AT 5 CPG SITES WAS PREVIOUSLY SHOWN TO CLASSIFY CHRONIC LYMPHOCYTIC LEUKEMIA (CLL) INTO 3 PROGNOSTIC SUBGROUPS. HERE, WE AIMED TO VALIDATE THE MARKER SET IN AN ADDITIONAL COHORT AND TO EVALUATE ITS CLINICAL UTILITY FOR CLL PATIENT STRATIFICATION. METHODS: WE EVALUATED THIS EPIGENETIC MARKER SET IN 79 GERMAN PATIENTS USING BISULFITE TREATMENT FOLLOWED BY PYROSEQUENCING AND CLASSIFICATION USING A SUPPORT VECTOR MACHINE-LEARNING TOOL. RESULTS: THE N-CLL, I-CLL, AND M-CLL CLASSIFICATION WAS DETECTED IN 28 (35%), 10 (13%), AND 41 (51%) PATIENTS, RESPECTIVELY. EPIGENETIC GROUPING WAS ASSOCIATED WITH IGHV MUTATIONAL STATUS (P = 2 X 10(-12)), ISOLATED DEL13Q (P = 9 X 10(-6)), DEL17P (P = .015), COMPLEX KARYOTYPE (P = .005), VH-USAGE, AND CLINICAL OUTCOME AS TIME TO FIRST TREATMENT (P = 1.4 X 10(-12)) AND OVERALL SURVIVAL (P = .003). MULTIVARIATE COX REGRESSION ANALYSIS IDENTIFIED N-CLL AS A FACTOR FOR EARLIER TREATMENT HAZARD RATIO (HR), 6.3 (95% CONFIDENCE INTERVAL [CI] 2.4-16.4; P = .0002) COMPARED TO IGHV MUTATIONAL STATUS (HR 4.6, 95% CI 1.9-11.3, P = .0008). IN ADDITION, WHEN COMPARING THE PROGNOSTIC VALUE OF THE EPIGENETIC CLASSIFICATION SYSTEM WITH THE IGHV CLASSIFICATION, EPIGENETIC GROUPING PERFORMED BETTER COMPARED TO IGHV MUTATIONAL STATUS USING KAPLAN-MEIER ESTIMATION AND ALLOWED THE IDENTIFICATION OF A THIRD, INTERMEDIATE (I-CLL) GROUP. THUS, OUR STUDY CONFIRMED THE PROGNOSTIC VALUE OF THE EPIGENETIC MARKER SET FOR PATIENT STRATIFICATION IN ROUTINE CLINICAL DIAGNOSTICS.	2022	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                         
8   779  29 CELL-FREE DNA PROMOTER HYPERMETHYLATION AS A DIAGNOSTIC MARKER FOR PANCREATIC DUCTAL ADENOCARCINOMA - AN EXTERNAL VALIDATION STUDY. BACKGROUND: WE RECENTLY IDENTIFIED A DIAGNOSTIC PREDICTION MODEL BASED ON PROMOTER HYPERMETHYLATION OF EIGHT SELECTED GENES IN PLASMA CELL-FREE (CF) DNA, WHICH SHOWED PROMISING RESULTS AS A DIAGNOSTIC BIOMARKER FOR PANCREATIC DUCTAL ADENOCARCINOMA (PDAC). THE AIM OF THE PRESENT STUDY WAS TO VALIDATE THIS BIOMARKER PROFILE IN AN EXTERNAL PATIENT COHORT AND EXAMINE ANY ADDITIONAL EFFECT OF SERUM CA 19-9. METHODS: PATIENTS WITH PDAC (N = 346, STAGE I-IV) AND CHRONIC PANCREATITIS (N = 25) WERE INCLUDED. METHYLATION-SPECIFIC PCR OF A 28-GENE PANEL WAS PERFORMED ON SERUM CFDNA SAMPLES. THE PREVIOUSLY DEVELOPED DIAGNOSTIC PREDICTION MODEL (AGE>65 YEARS, BMP3, RASSF1A, BNC1, MESTV2, TFPI2, APC, SFRP1 AND SFRP2) WAS VALIDATED ALONE AND IN COMBINATION WITH SERUM CA 19-9 IN THIS EXTERNAL PATIENT COHORT. RESULTS: PATIENTS WITH PDAC HAD A HIGHER NUMBER OF HYPERMETHYLATED GENES (MEAN 8.11, 95% CI 7.70-8.52) THAN PATIENTS WITH CHRONIC PANCREATITIS (MEAN 5.60, 95% CI 4.42-6.78, P = 0.011). VALIDATION OF THE DIAGNOSTIC PREDICTION MODEL YIELDED AN AUC OF 0.77 (95% CI 0.69-0.84). THE COMBINATION OF SERUM CA 19-9 AND OUR TEST HAD AN AUC OF 0.93 (95% CI 0.89-0.96) IN THE PRIMARY STUDY AND 0.85 (95% CI 0.79-0.91) IN THE VALIDATION STUDY. CONCLUSION: IN THIS VALIDATION STUDY, PDAC WAS ASSOCIATED WITH A HIGHER NUMBER OF HYPERMETHYLATED GENES IN SERUM CFDNA THAN CHRONIC PANCREATITIS. OUR DIAGNOSTIC TEST WAS SUPERIOR TO THE PREDICTIVE VALUE OF SERUM CA 19-9 ALONE IN BOTH THE PRIMARY AND THE VALIDATION STUDY. THE COMBINATION OF OUR TEST WITH CA 19-9 MAY SERVE AS A CLINICALLY USEFUL DIAGNOSTIC BIOMARKER FOR PDAC.	2021	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                  
9  4249  44 METHYLATION-BASED BIOLOGICAL AGE AND BREAST CANCER RISK. BACKGROUND: AGE IS ONE OF THE STRONGEST PREDICTORS OF CANCER, CHRONIC DISEASE, AND MORTALITY, BUT BIOLOGICAL RESPONSES TO AGING DIFFER AMONG PEOPLE. EPIGENETIC DNA MODIFICATIONS HAVE BEEN USED TO ESTIMATE "BIOLOGICAL AGE," WHICH MAY BE A USEFUL PREDICTOR OF DISEASE RISK. WE TESTED THIS HYPOTHESIS FOR BREAST CANCER. METHODS: USING A CASE-COHORT APPROACH, WE MEASURED BASELINE BLOOD DNA METHYLATION OF 2764 WOMEN ENROLLED IN THE SISTER STUDY, 1566 OF WHOM SUBSEQUENTLY DEVELOPED BREAST CANCER AFTER AN AVERAGE OF 6 YEARS. USING THREE PREVIOUSLY ESTABLISHED METHYLATION-BASED "CLOCKS" (HANNUM, HORVATH, AND LEVINE), WE DEFINED BIOLOGICAL AGE ACCELERATION FOR EACH WOMAN BY COMPARING HER ESTIMATED BIOLOGICAL AGE WITH HER CHRONOLOGICAL AGE. HAZARD RATIOS AND 95% CONFIDENCE INTERVALS FOR BREAST CANCER RISK WERE ESTIMATED USING COX REGRESSION MODELS. ALL STATISTICAL TESTS WERE TWO-SIDED. RESULTS: EACH OF THE THREE CLOCKS SHOWED THAT BIOLOGICAL AGE ACCELERATION WAS STATISTICALLY SIGNIFICANTLY ASSOCIATED WITH INCREASED RISK OF DEVELOPING BREAST CANCER (5-YEAR AGE ACCELERATION, HANNUM'S CLOCK: HAZARD RATIO [HR] = 1.10, 95% CONFIDENCE INTERVAL [CI] = 1.00 TO 1.21, P = .04; HORVATH'S CLOCK: HR = 1.08, 95% CI = 1.00 TO 1.17, P = .04; LEVINE'S CLOCK: HR = 1.15, 95% CI = 1.07 TO 1.23, P < .001). FOR LEVINE'S CLOCK, EACH 5-YEAR ACCELERATION IN BIOLOGICAL AGE CORRESPONDED WITH A 15% INCREASE IN BREAST CANCER RISK. ALTHOUGH BIOLOGICAL AGE MAY ACCELERATE WITH MENOPAUSAL TRANSITION, AGE ACCELERATION IN PREMENOPAUSAL WOMEN INDEPENDENTLY PREDICTED BREAST CANCER. CASE-ONLY ANALYSIS SUGGESTED THAT, AMONG WOMEN WHO DEVELOP BREAST CANCER, INCREASED AGE ACCELERATION IS ASSOCIATED WITH INVASIVE CANCER (ODDS RATIO FOR INVASIVE = 1.09, 95% CI = 0.98 TO 1.22, P = .10). CONCLUSIONS: DNA METHYLATION-BASED MEASURES OF BIOLOGICAL AGE MAY BE IMPORTANT PREDICTORS OF BREAST CANCER RISK.	2019	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                       
10  6689  28 VALPROIC ACID AT THERAPEUTIC PLASMA LEVELS MAY INCREASE 5-AZACYTIDINE EFFICACY IN HIGHER RISK MYELODYSPLASTIC SYNDROMES. PURPOSE: EPIGENETIC CHANGES PLAY A ROLE AND COOPERATE WITH GENETIC ALTERATIONS IN THE PATHOGENESIS OF MYELODYSPLASTIC SYNDROMES (MDS). WE CONDUCTED A PHASE II MULTICENTER STUDY ON THE COMBINATION OF THE DNA-METHYLTRANSFERASE INHIBITOR 5-AZACYTIDINE (5-AZA) AND THE HISTONE DEACETYLASE INHIBITOR VALPROIC ACID (VPA) IN PATIENTS WITH HIGHER RISK MDS. EXPERIMENTAL DESIGN: WE ENROLLED 62 PATIENTS WITH MDS (REFRACTORY ANEMIA WITH EXCESS BLASTS, 39 PATIENTS; REFRACTORY ANEMIA WITH EXCESS BLASTS IN TRANSFORMATION, 19 PATIENTS; AND CHRONIC MYELOMANOCYTIC LEUKEMIA (CMML), 4 PATIENTS) AND AN INTERNATIONAL PROGNOSTIC SCORING SYSTEM (IPSS) RATING OF INTERMEDIATE-2 (42 PATIENTS) OR HIGH (20 PATIENTS). VPA WAS GIVEN TO REACH A PLASMA CONCENTRATION OF >50 MICROG/ML, THEN 5-AZA WAS ADDED S.C. AT 75 MG/M(2) FOR 7 DAYS IN EIGHT MONTHLY CYCLES. RESULTS: THE MEDIAN OVERALL SURVIVAL WAS 14.4 MONTHS. AT A MEDIAN FOLLOW-UP OF 12 MONTHS (RANGE, 0.7-21.0), THE DISEASE PROGRESSED IN 20 PATIENTS, WITH 21% CUMULATIVE INCIDENCE OF PROGRESSION. OF 26 PATIENTS WHO COMPLETED EIGHT CYCLES, 30.7% OBTAINED COMPLETE OR PARTIAL REMISSION, 15.4% HAD A MAJOR HEMATOLOGIC IMPROVEMENT, WHEREAS 38.5% SHOWED STABLE DISEASE. DRUG-RELATED TOXICITY WAS MILD. FAVORABLE PROGNOSTIC FACTORS FOR SURVIVAL WERE IPSS INTERMEDIATE-2 AND PLASMA VPA OF > OR =50 MICROG/ML (LOG RANK = 0.013 AND 0.007, RESPECTIVELY). ANALYSIS OF POLYMORPHISMS IMPORTANT FOR THE METABOLISM OF THE DRUGS USED IN THE TRIAL SHOWED THAT CARRIERS OF THE CYP2C19*2 VARIANT OF CYTOCHROME P450 REQUIRED HIGHER VPA DOSES TO ACHIEVE THE TARGET VPA PLASMA CONCENTRATION OF 50 MICROG/ML ON DAY 1 OF 5-AZA TREATMENT (P = 0.0021). CONCLUSION: OUR DATA SHOW THAT THE 5-AZA/VPA COMBINATION IS ACTIVE AND SAFE IN PATIENTS WITH MDS WITH A POOR PROGNOSIS. ACHIEVEMENT OF VPA THERAPEUTIC LEVELS MAY INDEED INCREASE 5-AZA EFFICACY.	2009	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                           
11  4825  30 OCULAR FUNDUS ABNORMALITIES IN PATIENTS WITH BALKAN ENDEMIC NEPHROPATHY AND OTHER CHRONIC KIDNEY DISEASES. AIM: THE AIM OF THIS STUDY WAS TO EXAMINE THE OCULAR FUNDUS PATHOLOGY IN PATIENTS WITH BALKAN ENDEMIC NEPHROPATHY (BN) AND CHRONIC KIDNEY DISEASES (CKD). METHODS: THE STUDY INCLUDED 51 PATIENTS WITH BN FROM THE SOUTH MORAVA RIVER REGION IN SERBIA, AND 102 SUBJECTS WITH DIFFERENT STAGES OF CHRONIC RENAL DISEASES, MATCHED ACCORDING TO AGE AND GENDER, OBTAINED FROM A DATABASE USED IN A RECENTLY PUBLISHED STUDY. ALL PATIENTS HAD VISITED OUTPATIENT DEPARTMENT OF THE CLINIC OF NEPHROLOGY, CLINICAL CENTER NIS. ALL PATIENTS UNDERWENT ROUTINE OPHTHALMIC EXAMINATIONS. RESULTS: THERE WERE SIGNIFICANTLY MORE (P < 0.001) PATIENTS WITH AGE-RELATED MACULAR DEGENERATION (AMD) IN THE GROUP WITH BN (31.37 %) THAN IN THOSE WITH CKD (5.88 %). MULTIVARIATE LOGISTIC REGRESSION ANALYSIS CONFIRMED THAT THE SIGNIFICANT FACTORS RELATED TO AMD IN THE GROUP WITH BN WERE ALBUMINURIA (P < 0.05) AND PROTEINURIA (P < 0.05); IN CKD PATIENTS, THE LEVEL OF HDL (P < 0.05), WHILE NEGATIVE CORRELATION WITH THE LEVEL OF TRIGLYCERIDE WAS REGISTERED (P < 0.05). THERE WAS NO ASSOCIATION BETWEEN ESTIMATED GLOMERULAR FILTRATION RATE AND AMD. THE SIGNIFICANT FACTORS RELATED TO RETINOPATHY IN THE GROUP WITH BN ARE AGE (P < 0.05) AND SERUM CREATININE VALUES (P < 0.05), IN PATIENTS WITH CKD INCREASING AGE (P < 0.001) AND DM (P < 0.05). CONCLUSION: OCULAR FUNDUS PATHOLOGY IN PATIENTS WITH BN IS SIMILAR TO THE PATHOLOGY OF OTHER CKD, BUT WITH SIGNIFICANTLY MORE AMD (ABOUT FOUR TIMES), PROBABLY RELATED TO THE GENETIC/EPIGENETIC FACTORS.	2015	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                               
12   960  27 CHRONIC MYELOMONOCYTIC LEUKEMIA: 2016 UPDATE ON DIAGNOSIS, RISK STRATIFICATION, AND MANAGEMENT. CHRONIC MYELOMONOCYTIC LEUKEMIA (CMML) IS A CLONAL HEMATOPOIETIC STEM CELL DISORDER CHARACTERIZED BY OVERLAPPING FEATURES OF MYELODYSPLASTIC SYNDROMES AND MYELOPROLIFERATIVE NEOPLASMS. DIAGNOSIS IS BASED ON THE PRESENCE OF PERSISTENT (>3 MONTHS) PERIPHERAL BLOOD MONOCYTOSIS (>1 X 10(9) /L), ALONG WITH BONE MARROW DYSPLASIA. CLONAL CYTOGENETIC ABNORMALITIES OCCUR IN APPROXIMATELY 20-30% OF PATIENTS, WHILE >90% HAVE GENE MUTATIONS. MUTATIONS INVOLVING TET2 ( APPROXIMATELY 60%), SRSF2 ( APPROXIMATELY 50%), ASXL1 ( APPROXIMATELY 40%), AND RAS ( APPROXIMATELY 30%) ARE FREQUENT; WITH ONLY ASXL1 MUTATIONS NEGATIVELY IMPACTING OVERALL SURVIVAL. TWO MOLECULARLY INTEGRATED, CMML-SPECIFIC PROGNOSTIC MODELS INCLUDE; THE GROUPE FRANCAIS DES MYELODYSPLASIES (GFM) AND THE MOLECULAR MAYO MODEL (MMM). THE GFM MODEL SEGREGATES PATIENTS INTO 3 GROUPS BASED ON: AGE >65 YEARS, WBC >15 X 10(9) /L, ANEMIA, PLATELETS <100 X 10(9) /L, AND ASXL1 MUTATION STATUS, WITH RESPECTIVE MEDIAN SURVIVALS OF 56 (LOW), 27.4 (INTERMEDIATE), AND 9.2 (HIGH) MONTHS. THE MMM IS BASED ON ASXL1 MUTATIONAL STATUS, ABSOLUTE MONOCYTE COUNT >10 X 10(9) /L, HEMOGLOBIN <10 G/DL, PLATELETS <100 X 109/L AND CIRCULATING IMMATURE MYELOID CELLS. THIS MODEL STRATIFIES PATIENTS INTO FOUR GROUPS; HIGH (>/=3 RISK FACTORS), INTERMEDIATE-2 (2 RISK FACTORS), INTERMEDIATE-1 (1 RISK FACTOR) AND LOW (NO RISK FACTORS), WITH MEDIAN SURVIVALS OF 16, 31, 59, AND 97 MONTHS, RESPECTIVELY. HYPOMETHYLATING AGENTS SUCH AS 5-AZACITIDINE AND DECITABINE ARE COMMONLY USED, WITH OVERALL RESPONSE RATES OF APPROXIMATELY 30-40% AND COMPLETE REMISSION RATES OF APPROXIMATELY 7-17%. ALLOGENEIC STEM CELL TRANSPLANT IS THE ONLY POTENTIALLY CURATIVE OPTION, BUT IS ASSOCIATED WITH SIGNIFICANT MORBIDITY AND MORTALITY. INDIVIDUALIZED THERAPY, INCLUDING EPIGENETIC MODIFIERS AND SMALL MOLECULE INHIBITORS, ARE EXCITING PROSPECTS. AM. J. HEMATOL. 91:632-642, 2016.

13  3560  29 IMPACT OF CLINICAL, CYTOGENETIC, AND MOLECULAR PROFILES ON LONG-TERM SURVIVAL AFTER TRANSPLANTATION IN PATIENTS WITH CHRONIC MYELOMONOCYTIC LEUKEMIA. CHRONIC MYELOMONOCYTIC LEUKEMIA (CMML) IS A HETEROGENEOUS GROUP OF CLONAL HEMATOPOIETIC MALIGNANCIES WITH VARIABLE CLINICAL AND MOLECULAR FEATURES. WE ANALYZED LONG-TERM RESULTS OF ALLOGENEIC HEMATOPOIETIC CELL TRANSPLANTATION IN PATIENTS WITH CMML AND DETERMINED CLINICAL AND MOLECULAR RISK FACTORS ASSOCIATED WITH OUTCOMES. DATA FROM 129 PATIENTS, AGED 7-74 (MEDIAN 55) YEARS, AT VARIOUS STAGES OF THE DISEASE AND TRANSPLANTED FROM RELATED OR UNRELATED DONORS WERE ANALYZED. USING A PANEL OF 75 GENES SOMATIC MUTATIONS PRESENT BEFORE HEMATOPOIETIC CELL TRANSPLANTATION WERE IDENTIFIED IN 52 PATIENTS. THE PROGRESSION-FREE SURVIVAL RATE AT 10 YEARS WAS 29%. THE MAJOR CAUSE OF DEATH WAS RELAPSE (32%), WHICH WAS SIGNIFICANTLY ASSOCIATED WITH ADVERSE CYTOGENETICS (HAZARD RATIO, 3.77; P=0.0002), CMML PROGNOSTIC SCORING SYSTEM (HAZARD RATIO, 14.3, P=0.01), AND MD ANDERSON PROGNOSTIC SCORES (HAZARD RATIO, 9.4; P=0.005). MORTALITY WAS ASSOCIATED WITH HIGH-RISK CYTOGENETICS (HAZARD RATIO, 1.88; P=0.01) AND HIGH HEMATOPOIETIC CELL TRANSPLANTATION COMORBIDITY INDEX (SCORE >/=4: HAZARD RATIO, 1.99; P=0.01). HIGH OVERALL MUTATION BURDEN (>/=10 MUTATIONS: HAZARD RATIO, 3.4; P=0.02), AND >/=4 MUTATED EPIGENETIC REGULATORY GENES (HAZARD RATIO 5.4; P=0.003) WERE LINKED TO RELAPSE. UNSUPERVISED CLUSTERING OF THE CORRELATION MATRIX REVEALED DISTINCT HIGH-RISK GROUPS WITH UNIQUE ASSOCIATIONS OF MUTATIONS AND CLINICAL FEATURES. CMML WITH A HIGH MUTATION BURDEN APPEARED TO BE DISTINCT FROM HIGH-RISK GROUPS DEFINED BY COMPLEX CYTOGENETICS. NEW TRANSPLANT STRATEGIES MUST BE DEVELOPED TO TARGET SPECIFIC DISEASE SUBGROUPS, STRATIFIED BY MOLECULAR PROFILING AND CLINICAL RISK FACTORS.	2020	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                            
14  4245  36 METHYLATION STATUS OF DDIT3 GENE IN CHRONIC MYELOID LEUKEMIA. BACKGROUND: DNA-DAMAGE-INDUCIBLE TRANSCRIPT 3 (DDIT3), A CANDIDATE TUMOR SUPPRESSOR GENE (TSG), HAS BEEN FOUND INVOLVED IN THE REGULATION OF CELLULAR GROWTH AND DIFFERENTIATION. THE EPIGENETIC CHANGES OF TSGS ARE RECENTLY RECOGNIZED AS AN ABNORMAL MECHANISM CONTRIBUTING TO THE DEVELOPMENT OF CHRONIC MYELOID LEUKEMIA (CML). THE AIM OF THIS STUDY WAS TO INVESTIGATE THE METHYLATION STATUS OF DDIT3 GENE IN CML PATIENTS. METHODS: THE METHYLATION STATUS OF DDIT3 PROMOTER WAS DETECTED IN THE BONE MARROW MONONUCLEAR CELLS FROM 53 PATIENTS WITH CML USING METHYLATION-SPECIFIC PCR (MSP). THE EXPRESSION LEVELS OF DDIT3 AND BCR/ABL TRANSCRIPT WERE DETERMINED BY REAL-TIME QUANTITATIVE PCR (RQ-PCR). CLINICAL DATA OF THESE PATIENTS WERE COLLECTED AND ANALYZED. RESULTS: THE ABERRANT METHYLATION OF DDIT3 GENE PROMOTER WAS FOUND IN 35 OF 53 (66%) CML CASES. CORRELATION WAS NOT FOUND BETWEEN DDIT3 PROMOTER HYPERMETHYLATION AND THE AGE, SEX, HEMOGLOBIN CONCENTRATION, PLATELET COUNTS, CHROMOSOMAL ABNORMALITIES, BCR/ABL TRANSCRIPT, AND STAGING OF CML PATIENTS (P > 0.05), BUT FOUND BETWEEN DDIT3 PROMOTER HYPERMETHYLATION AND WBC COUNTS OF CML CASES (R = 0.781, P < 0.001). THE LEVEL OF DDIT3 TRANSCRIPT IN CML PATIENTS WAS SIGNIFICANTLY LOWER THAN THAT IN CONTROLS (MEDIAN 3.28 VS 19.69, P < 0.001), HOWEVER, THERE WAS NO DIFFERENCE IN THE LEVEL OF DDIT3 TRANSCRIPT BETWEEN METHYLATION-POSITIVE CML CASES (0.05-65.32, MEDIAN 2.13) AND METHYLATION- NEGATIVE CML CASES (0.12-126.04, MEDIAN 3.92) (P > 0.05). CONCLUSION: OUR RESULTS DEMONSTRATE THAT ABERRANT METHYLATION OF DDIT3 OCCURS IN CML FREQUENTLY.	2010	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                       
15  6208  32 THE INTERACTION BETWEEN MICRORNA-152 AND DNA METHYLTRANSFERASE-1 AS AN EPIGENETIC PROGNOSTIC BIOMARKER IN HCV-INDUCED LIVER CIRRHOSIS AND HCC PATIENTS. THE NECESSITY FOR EARLY DETECTION AND HENCE IMPROVING THE OUTCOME OF TREATMENT OF HEPATOCELLULAR CARCINOMA (HCC) IS CRITICAL ESPECIALLY IN HEPATITIS C VIRUS (HCV)-GENOTYPE 4 INDUCED CASES. IN OUR CURRENT WORK, WE EXAMINED THE MIRNA-152 AND DNMT-1 EXPRESSION IN CHRONIC LIVER DISEASE (CLD) DUE TO HCV GENOTYPE 4 INFECTION WITH/WITHOUT CIRRHOSIS AND HCC PATIENTS AS AN ATTEMPT TO EVALUATE THE POTENTIAL BENEFITS OF THESE NEW CIRCULATING, NONINVASIVE, PROGNOSTIC, EPIGENETIC MARKERS FOR LIVER CIRRHOSIS AND CARCINOGENESIS OF EGYPTIAN PATIENTS. EIGHTY SUBJECTS WERE INCLUDED IN THIS STUDY, DIVIDED INTO TWO GROUPS; GROUP I (40 PATIENTS) WERE CLASSIFIED INTO SUBGROUP IA (CLD WITHOUT CIRRHOSIS, N = 18) AND SUBGROUP IB (CLD WITH CIRRHOSIS, N = 22), GROUP II (CLD PATIENTS WITH HCC, N = 20), AND CONTROL (HEALTHY VOLUNTEER, N = 20). THE EXPRESSION OF MIRNA-152 AND DNMT-1 GENES WERE ANALYZED USING REAL-TIME PCR. MIRNA-152 SHOWED A PERSISTENT AND SIGNIFICANT DOWNREGULATION IN ALL DISEASED GROUPS, WHICH WAS IN CONSISTENCE WITH THE PROGRESSION OF THE DISEASE TOWARD THE HCC STAGE. DNMT-1 SHOWED UPREGULATION IN ALL DISEASED GROUPS WHEN COMPARED TO CONTROL AND SUBGROUP IA. THE MIRNA-152 WAS SHOWN TO CORRELATE INVERSELY WITH DNMT-1 IN SUBGROUP IA, IB AND GROUP II (R = -0.557, P < 0.01), (R = -0.850, P < 0.001) AND (R = -0.544, P < 0.02) RESPECTIVELY. IN ADDITION, MIRNA-152 AND DNMT-1 SHOWED A DIAGNOSTIC ABILITY TO DISCRIMINATE BETWEEN CASES OF CIRRHOSIS AND HCC AGAINST CLD WITHOUT CIRRHOSIS (P < 0.01), WHILE DNMT-1 DID NOT, EXCEPT BETWEEN HCC AND CIRRHOTIC CASES. FURTHERMORE, BOTH GENES CAN BE CONSIDERED AS PREDICTOR AND PROGNOSTIC PARAMETERS FOR CIRRHOSIS (OR = 1.041, P = 0.043) AND (OR = 1.039, P = 0.04) RESPECTIVELY, WHILE MIRNA-152 ALONE IS PROVED AS A PROGNOSTIC MARKER FOR HCC (OR = 1.003, P = 0.044). FINALLY, THE PERSISTENT REVERSE CORRELATION BETWEEN MIRNA-152 WITH DNMT-1 PROMPTS THEIR USE AS NONINVASIVE PROGNOSTIC BIOMARKERS FOR HCV INDUCED LIVER CIRRHOSIS AND HCC IN HCV GENOTYPE 4 PATIENTS.	2020	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                 
16  1785  30 EFFECT OF APABETALONE ON CARDIOVASCULAR EVENTS IN DIABETES, CKD, AND RECENT ACUTE CORONARY SYNDROME: RESULTS FROM THE BETONMACE RANDOMIZED CONTROLLED TRIAL. BACKGROUND AND OBJECTIVES: CKD AND TYPE 2 DIABETES MELLITUS INTERACT TO INCREASE THE RISK OF MAJOR ADVERSE CARDIOVASCULAR EVENTS (I.E., CARDIOVASCULAR DEATH, NONFATAL MYOCARDIAL INFARCTION, OR STROKE) AND CONGESTIVE HEART FAILURE. A MALADAPTIVE EPIGENETIC RESPONSE MAY BE A CARDIOVASCULAR RISK DRIVER AND AMENABLE TO MODIFICATION WITH APABETALONE, A SELECTIVE MODULATOR OF THE BROMODOMAIN AND EXTRATERMINAL DOMAIN TRANSCRIPTION SYSTEM. WE EXAMINED THIS QUESTION IN A PRESPECIFIED ANALYSIS OF BETONMACE, A PHASE 3 TRIAL. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS: BETONMACE WAS AN EVENT-DRIVEN, RANDOMIZED, DOUBLE-BLIND, PLACEBO-CONTROLLED TRIAL COMPARING EFFECTS OF APABETALONE VERSUS PLACEBO ON MAJOR ADVERSE CARDIOVASCULAR EVENTS AND HEART FAILURE HOSPITALIZATIONS IN 2425 PARTICIPANTS WITH TYPE 2 DIABETES AND A RECENT ACUTE CORONARY SYNDROME, INCLUDING 288 PARTICIPANTS WITH CKD WITH EGFR <60 ML/MIN PER 1.73 M(2) AT BASELINE. THE PRIMARY END POINT IN BETONMACE WAS THE TIME TO THE FIRST MAJOR ADVERSE CARDIOVASCULAR EVENT, WITH A SECONDARY END POINT OF TIME TO HOSPITALIZATION FOR HEART FAILURE. RESULTS: MEDIAN FOLLOW-UP WAS 27 MONTHS (INTERQUARTILE RANGE, 20-32 MONTHS). IN PARTICIPANTS WITH CKD, APABETALONE COMPARED WITH PLACEBO WAS ASSOCIATED WITH FEWER MAJOR ADVERSE CARDIOVASCULAR EVENTS (13 EVENTS IN 124 PATIENTS [11%] VERSUS 35 EVENTS IN 164 PATIENTS [21%]; HAZARD RATIO, 0.50; 95% CONFIDENCE INTERVAL, 0.26 TO 0.96) AND FEWER HEART FAILURE-RELATED HOSPITALIZATIONS (THREE HOSPITALIZATIONS IN 124 PATIENTS [3%] VERSUS 14 HOSPITALIZATIONS IN 164 PATIENTS [9%]; HAZARD RATIO, 0.48; 95% CONFIDENCE INTERVAL, 0.26 TO 0.86). IN THE NON-CKD GROUP, THE CORRESPONDING HAZARD RATIO VALUES WERE 0.96 (95% CONFIDENCE INTERVAL, 0.74 TO 1.24) FOR MAJOR ADVERSE CARDIOVASCULAR EVENTS, AND 0.76 (95% CONFIDENCE INTERVAL, 0.46 TO 1.27) FOR HEART FAILURE-RELATED HOSPITALIZATION. INTERACTION OF CKD ON TREATMENT EFFECT WAS P=0.03 FOR MAJOR ADVERSE CARDIOVASCULAR EVENTS, AND P=0.12 FOR HEART FAILURE-RELATED HOSPITALIZATION. PARTICIPANTS WITH CKD SHOWED SIMILAR NUMBERS OF ADVERSE EVENTS, REGARDLESS OF RANDOMIZATION TO APABETALONE OR PLACEBO (119 [73%] VERSUS 88 [71%] PATIENTS), AND THERE WERE FEWER SERIOUS ADVERSE EVENTS (29% VERSUS 43%; P=0.02) IN THE APABETALONE GROUP. CONCLUSIONS: APABETALONE MAY REDUCE THE INCIDENCE OF MAJOR ADVERSE CARDIOVASCULAR EVENTS IN PATIENTS WITH CKD AND TYPE 2 DIABETES WHO HAVE A HIGH BURDEN OF CARDIOVASCULAR DISEASE.	2021	
                                                           
17  2135  41 EPIGENETIC INACTIVATION OF TUMOR SUPPRESSOR GENES IN SERUM OF PATIENTS WITH CUTANEOUS MELANOMA. SMALL AMOUNTS OF CELL-FREE DNA CIRCULATE IN BOTH HEALTHY AND DISEASED HUMAN BLOOD, WHILE INCREASED CONCENTRATIONS OF DNA ARE PRESENT IN THE SERUM OF CANCER PATIENTS. TUMOR-SPECIFIC MUTATIONS OR EPIGENETIC MODIFICATIONS HAVE PREDOMINANTLY BEEN DETECTED IN TISSUE SPECIMENS. THE PURPOSE OF THIS STUDY WAS TO INVESTIGATE METHYLATION OF FIVE DIFFERENT GENES INVOLVED IN TUMOR SUPPRESSION AND DNA REPAIR (SUPPRESSORS OF CYTOKINE SIGNALING 1 AND 2 (SOCS1, SOCS2)), RAS-ASSOCIATION DOMAIN FAMILY PROTEIN 1A (RASSF1A), D-TYPE P16(INK4A) CYCLIN-DEPENDENT KINASE INHIBITOR (CDKN), AND O6-METHYLGUANINE DNA-METHYLTRANSFERASE (MGMT)) IN THE SERUM OF 100 PATIENTS USING METHYLATION-SPECIFIC PCR. IN ALL, 41 MELANOMA PATIENTS (STAGE I = 18; STAGE II = 10; STAGE III/IV = 13), 13 HEALTHY CONTROLS WITHOUT NEVI, AND 10 INDIVIDUALS WITH MORE THAN 15 NEVI OF >5 MM IN SIZE WERE INVESTIGATED. FOR COMPARISON, SERA FROM PATIENTS WITH OTHER SKIN TUMORS (NINE BASAL CELL CANCERS, FIVE KAPOSI'S SARCOMA), DIFFERENT METASTASIZED CANCERS (FIVE BREAST CANCERS, FIVE COLON CANCERS), AND SEVERAL CHRONIC INFLAMMATORY DISEASES (N = 12) WERE ALSO ANALYZED. IN ADDITION, WE EXAMINED IF METHYLATION WAS INVOLVED IN SILENCING TRANSCRIPTION OF THESE GENES IN 12 MELANOMA SPECIMENS. SOCS1, SOCS2, RASSF1A, CDKN2A, AND MGMT WERE METHYLATED IN 75, 43, 64, 75, AND 64% OF MELANOMA SAMPLES, RESPECTIVELY. OF THE 41 MELANOMA PATIENTS, 83% HAD ONE HYPERMETHYLATED GENE, WHILE 66, 51, AND 41% HAD TWO, THREE, OR FOUR HYPERMETHYLATED GENES, RESPECTIVELY. ALSO, 20% OF THESE PATIENTS SHOWED HYPERMETHYLATION FOR ALL GENES, WHILE ONLY 17% SHOWED NO METHYLATION. IMPORTANTLY, THE METHYLATION PROFILE OF THE SELECTED GENES FROM MELANOMA PATIENTS WAS DISTINCT FROM THE OTHER ANALYZED TUMORS. TRANSCRIPTION OF SOCS1, SOCS2, CDKN2A, AND RASSF1A GENES WAS SIGNIFICANTLY REDUCED IN FRESH MELANOMA SAMPLES, WHILE MGMT SHOWED A 12-FOLD UPREGULATION AT THE MESSENGER RIBONUCLEIC ACID LEVEL (P < 0.001). OUR FINDINGS SUGGEST THAT EPIGENETIC SILENCING OF THE STUDIED TUMOR SUPPRESSOR GENES IS A COMMON AND PROBABLY IMPORTANT MECHANISM FOR MELANOMA FORMATION. THIS CONVENIENT METHOD USING A SIMPLE BLOOD SAMPLE MAY CONTRIBUTE TO CLASSIFICATION OF MELANOMA AND AWAITS CLINICAL VALIDATION.	2006	
                                                                                                                                                                                                                                                                                                                                                            
18  1735  32 EARLY AND SUSTAINED EXPANSION OF ADAPTIVE NATURAL KILLER CELLS FOLLOWING HAPLOIDENTICAL TRANSPLANTATION AND CTLA4IG-PRIMED DONOR LYMPHOCYTE INFUSIONS DISSOCIATE GRAFT-VERSUS-LEUKEMIA AND GRAFT-VERSUS-HOST EFFECTS. BACKGROUND: ADAPTIVE OR MEMORY NATURAL KILLER (NK) CELLS WITH EPIGENETIC IMPRINTS SIMILAR TO MEMORY T CELLS HAVE BEEN SHOWN TO DEVELOP IN RESPONSE TO CYTOMEGALOVIRUS (CMV) INFECTION WITH UPREGULATION OF ACTIVATING RECEPTOR NKG2C. THESE CELLS HAVE BEEN SHOWN TO POSSESS STRONG ANTI-TUMOUR EFFICACY BOTH IN-VITRO AS WELL AS IN-VIVO. OBJECTIVES: TO DETERMINE IF RECONSTITUTION OF ADAPTIVE NK CELLS (CD56(DIM)NKG2C(+)NKG2A(-)) IN PATIENTS WITH ADVANCED LEUKEMIA UNDERGOING HAPLOIDENTICAL HCT HAD ANY IMPACT ON DISEASE PROGRESSION (DP). STUDY DESIGN: THE STUDY COHORT COMPRISED OF 60 PATIENTS WITH ADVANCED ACUTE LEUKEMIA, AGED 2-65 YEARS, RECEIVING MYELOABLATIVE PTCY BASED HAPLOIDENTICAL TRANSPLANTATION FROM CMV SEROPOSITIVE DONORS, FOLLOWED BY CTLA4IG-PRIMED DONOR LYMPHOCYTE INFUSIONS (DLI). THEY WERE EVALUATED FOR THE KINETICS OF RECONSTITUTION OF ADAPTIVE NK CELLS, BOTH PHENOTYPIC AND FUNCTIONAL, AT DAYS +30,+60, +90 AND AT REGULAR INTERVALS, TO 3 YEARS OF FOLLOW-UP, IN RELATION TO DP. RECONSTITUTION OF ADAPTIVE NK CELLS WAS COMPARED WITH A RETROSPECTIVE COHORT OF PATIENTS IN THE SAME PROTOCOL RECEIVING DLI WITHOUT CTLA4IG. RESULTS: NON-RELAPSE MORTALITY, ACUTE AND CHRONIC GVHD WERE 5.1%, 10.3% AND 14.5%. DP WAS 17.5% AT A MEDIAN FOLLOW-UP OF 28 MONTHS. ADAPTIVE NK CELLS WERE SIGNIFICANTLY HIGHER IN PATIENTS WITHOUT DP AT DAYS+30, +60 AND +90 (P = 0.0001), IRRESPECTIVE OF CMV REACTIVATION AND REMAINED ELEVATED UNTIL 36 MONTHS POST-HCT. THESE CELLS MAINTAINED THEIR FUNCTIONAL COMPETENCE AS MEASURED BY ROBUST INTERFERON-GAMMA PRODUCTION WITH HIGHER EXPRESSIONS OF KIR, NKG2D AND CD57, WITHOUT ANY INCREASE IN PD1 EXPRESSION. GRAFTS FROM DONORS WITH HIGHER ADAPTIVE NK CELLS WERE ASSOCIATED WITH A LOWER RISK OF DP (P = 0.0001). IN MULTIVARIATE ANALYSIS, ADAPTIVE NK CELL RECOVERY AT DAY +90 HAD THE MOST FAVORABLE IMPACT ON DP (HR-0.7). TREGS RECONSTITUTED BRISKLY ALONG WITH THE ADAPTIVE NK CELLS AND WERE SUSTAINED AS WELL, WITHOUT COMPROMISING THE GVL EFFECT. COMPARISON WITH A RETROSPECTIVE COHORT RECEIVING THE SAME PROTOCOL WITH DLI WITHOUT CTLA4IG, SHOWED A SUPERIOR RECONSTITUTION OF ADAPTIVE NK CELLS IN THOSE RECEIVING CTLA4IG-DLI (P < 0.0001). CONCLUSION: OUR STUDY SUGGESTS THAT MYELOABLATIVE TRANSPLANTATION FROM CMV SEROPOSITIVE HAPLOIDENTICAL DONORS AUGMENTED WITH CTLA4IG-PRIMED DLI MIGHT FAVOR EARLY AND SUSTAINED EXPANSION OF FUNCTIONALLY COMPETENT ADAPTIVE NK CELLS IRRESPECTIVE OF CMV REACTIVATION, WITH A FAVORABLE OUTCOME.	2021	

19   517  38 ASSOCIATION STUDY OF FOXO3A SINGLE-NUCLEOTIDE POLYMORPHISM AND BRONCHIAL ASTHMA IN EGYPTIAN CHILDREN. ASTHMA IS THE MOST COMMON CHRONIC ILLNESS IN CHILDREN AND IS A LEADING CAUSE OF CHILDHOOD HOSPITALIZATION AND SCHOOL ABSENTEEISM. ASTHMA PRESENTS WITH DIFFERENT PHENOTYPES DEPENDING ON AGE, GENDER, GENETIC BACKGROUND, ENVIRONMENTAL EXPOSURES AND EPIGENETIC FACTORS. FORKHEAD BOX O3 (FOXO3) IS A TRANSCRIPTION FACTOR INVOLVED IN THE PATHOGENESIS OF A NUMBER OF INFLAMMATORY AND RESPIRATORY DISEASES. THE STUDY AIMS TO INVESTIGATE THE ASSOCIATION BETWEEN THE SNP RS13217795 IN FOXO3 GENE AND PEDIATRIC ONSET ASTHMA IN THE EGYPTIAN POPULATION. NINETY ASTHMATICS AND 160 HEALTHY CONTROLS WERE SUBJECTED TO GENOTYPING OF FOXO3 SNP (RS13217795) USING THE PCR-RFLP METHOD. THE PROPORTION OF HOMOZYGOUS (CC) AND HETEROZYGOUS (CT) GENOTYPES WAS LOWER IN THE ASTHMATIC GROUP COMPARED TO THE CONTROL GROUP BUT STATISTICALLY INSIGNIFICANT; P > 0.05. ON THE OTHER HAND THE PROPORTION OF THE MUTANT HOMOZYGOUS (TT) GENOTYPE IN ASTHMATIC GROUP WAS HIGHER; 30 (33.3%) THAN THE CONTROL GROUP; 28(17.5%), THE DIFFERENCE WAS SIGNIFICANT IN RECESSIVE MODEL OF DISEASE PENETRANCE WITH ODDS RATIO OR (95% CI) OF 2.4(1 - 5.49) AND P=0.039. THIS ASSOCIATION WAS MORE PRONOUNCED IN MALE GENDER; OR AND 95% CI OF 5.3 (1.4- 19.3) AND P=0.01. IN CONCLUSIONS, EGYPTIAN CHILDREN CARRYING THE MUTANT (TT) GENOTYPE WERE AT HIGHER RISK TO DEVELOP ASTHMA WITH A HIGHER RISK IN MALE GENDER.	2020	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                
20   817  36 CHARACTERISTIC PATTERNS OF ALTERED DNA METHYLATION PREDICT EMERGENCE OF HUMAN HEPATOCELLULAR CARCINOMA. WE AIMED TO IDENTIFY THE SPECIFIC SUBSET OF TUMOR SUPPRESSOR GENES (TSGS) THAT ARE METHYLATION-SILENCED DURING THE EARLIEST STEPS OF HEPATOCARCINOGENESIS, AND TO FURTHER EVALUATE WHETHER THESE GENES CAN SERVE AS PREDICTIVE BIOMARKERS OF HEPATOCELLULAR CARCINOMA (HCC) EMERGENCE. A TOTAL OF 482 LIVER TISSUES INCLUDING 177 PAIRS OF HCCS AND MATCHED NONTUMOR LIVERS AND 128 LIVER BIOPSIES FROM CHRONIC HEPATITIS C (CHC) PATIENTS WERE ANALYZED FOR QUANTITATIVE METHYLATION ANALYSIS IN 24 TSG PROMOTERS AND THREE MINT LOCI. THE TUMORS WERE CLASSIFIED AS EARLY, LESS-PROGRESSED, AND HIGHLY PROGRESSED HCCS USING HISTOLOGY AND RADIOLOGICAL APPROACHES. A SUBSET OF TSGS THAT HARBORED DISTINCTLY HIGH LEVELS OF METHYLATION IN EARLY HCCS WERE SELECTED. BASED ON THE METHYLATION PROFILES OF THESE GENES, KAPLAN-MEIER ANALYSES WERE PERFORMED TO DETERMINE TIME-TO-HCC OCCURRENCE IN CHC PATIENTS. SUBSEQUENTLY, MULTIVARIATE ANALYSIS WAS PERFORMED USING AGE, GENDER, FIBROSIS STAGE, AND NUMBER OF METHYLATED TSGS AS COVARIATES. AMONG TSGS ANALYZED, A SUBSET OF EIGHT TSGS (HIC1, GSTP1, SOCS1, RASSF1, CDKN2A, APC, RUNX3, AND PRDM2) DEMONSTRATED A DISTINCT CLUSTER BY HIERARCHICAL CLUSTERING AND RECEIVER OPERATING CHARACTERISTIC ANALYSES. THIS SUBSET OF TSGS SHOWED SIGNIFICANTLY HIGHER METHYLATION LEVELS IN THE EARLY HCCS (P < 0.0001). IN THE CHC PATIENTS, METHYLATION FREQUENCIES IN THESE TSGS WERE ASSOCIATED WITH SHORTER TIME-TO-HCC OCCURRENCE (P < 0.0001), AND NUMBER OF METHYLATED GENES WAS AN INDEPENDENT RISK FACTOR FOR HCC (HAZARD RATIO = 5.21, 95% CONFIDENCE INTERVAL = 2.25-11.76, P = 0.0002). CONCLUSION: EPIGENETIC INACTIVATION OF A SUBSET OF TSGS PLAYS A CRITICAL ROLE IN THE EARLIEST STEPS OF HEPATOCARCINOGENESIS. FURTHERMORE, EPIGENETIC INACTIVATION OF THESE GENES IN CHC PROVIDES A PROGNOSTIC VALUE FOR DETERMINING THE RISK FOR DEVELOPING HCC LATER IN LIFE.	2012
