1  5234 137 PROFILE ANALYSIS AND FUNCTIONAL MODELING IDENTIFY CIRCULAR RNAS IN NONALCOHOLIC FATTY LIVER DISEASE AS REGULATORS OF HEPATIC LIPID METABOLISM. NONALCOHOLIC FATTY LIVER DISEASE (NAFLD) IS THE LEADING CAUSE OF CHRONIC LIVER DISEASE, ASSOCIATED WITH AN OUTCOME OF HEPATIC FIBROSIS/CIRRHOSIS AND HEPATOCELLULAR CARCINOMA. HOWEVER, LIMITED EXPLORATION OF THE UNDERLYING MECHANISMS HINDERS ITS PREVENTION AND TREATMENT. TO INVESTIGATE THE MECHANISMS OF EPIGENETIC REGULATION IN NAFLD, THE EXPRESSION PROFILE OF CIRCULAR RNA (CIRCRNA) OF RODENTS IN WHICH NAFLD WAS INDUCED BY A HIGH-FAT, HIGH-CHOLESTEROL (HFHC) DIET WAS STUDIED. MODELING OF THE CIRCRNA-MICRORNA (MIRNA) -MRNA REGULATORY NETWORK REVEALED THE FUNCTIONAL CHARACTERISTICS OF NAFLD-SPECIFIC CIRCRNAS. THE TARGETS AND EFFECTS IN THE LIVER OF SUCH NAFLD-SPECIFIC CIRCRNAS WERE FURTHER ASSESSED. OUR RESULTS UNCOVERED THAT THE DOWNREGULATION OF 28 ANNOTATED CIRCRNAS CHARACTERIZES HFHC DIET-INDUCED NAFLD. AMONG THE DOWNREGULATED CIRCRNAS, LONG INTERGENIC NON-PROTEIN CODING RNA, P53 INDUCED TRANSCRIPT (LNCPINT) -DERIVED CIRCRNAS (CIRC_0001452, CIRC_0001453, AND CIRC_0001454) TARGETED BOTH MIR-466I-3P AND MIR-669C-3P. THEIR DEFICIENCY IN NAFLD ABROGATED THE CIRCRNA-BASED INHIBITORY EFFECT ON BOTH MIRNAS, WHICH FURTHER INACTIVATED THE AMPK SIGNALING PATHWAY VIA AMPK-ALPHA1 SUPPRESSION. INHIBITION OF THE AMPK SIGNALING PATHWAY PROMOTES HEPATIC STEATOSIS, DEPENDING ON THE TRANSCRIPTIONAL AND TRANSLATIONAL UPREGULATION OF LIPOGENIC GENES, SUCH AS THOSE ENCODING STEROL REGULATORY ELEMENT-BINDING PROTEIN 1 (SREBP1) AND FATTY ACID SYNTHASE (FASN) IN HEPATOCYTES. THE LEVELS OF LNCPINT-DERIVED CIRCRNAS DISPLAYED A NEGATIVE ASSOCIATION WITH HEPATIC TRIGLYCERIDE (TG) CONCENTRATION. THESE FINDINGS SUGGEST THAT LOSS OF LNCPINT-DERIVED CIRCRNAS MAY UNDERLIE NAFLD VIA MIR-466I-3P- AND MIR-669C-3P-DEPENDENT INACTIVATION OF THE AMPK SIGNALING PATHWAY.	2022	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                              
2  3504  34 IDENTIFICATION OF POTENTIALLY FUNCTIONAL CIRCRNAS AND PREDICTION OF CIRCRNA-MIRNA-MRNA REGULATORY NETWORK IN PERIODONTITIS: BRIDGING THE GAP BETWEEN BIOINFORMATICS AND CLINICAL NEEDS. BACKGROUND AND OBJECTIVE: PERIODONTITIS IS A MULTIFACTORIAL CHRONIC INFLAMMATORY DISEASE THAT CAN LEAD TO THE IRREVERSIBLE DESTRUCTION OF DENTAL SUPPORT TISSUES. AS AN EPIGENETIC FACTOR, THE EXPRESSION OF CIRCRNA IS TISSUE-DEPENDENT AND DISEASE-DEPENDENT. THIS STUDY AIMED TO IDENTIFY NOVEL PERIODONTITIS-ASSOCIATED CIRCRNAS AND PREDICT RELEVANT CIRCRNA-PERIODONTITIS REGULATORY NETWORK BY USING RECENTLY DEVELOPED BIOINFORMATIC TOOLS AND INTEGRATING SEQUENCING PROFILING WITH CLINICAL INFORMATION FOR GETTING A BETTER AND MORE THOROUGH IMAGE OF PERIODONTITIS PATHOGENESIS, FROM GENE TO CLINIC. MATERIAL AND METHODS: HIGH-THROUGHPUT SEQUENCING AND RT-QPCR WERE CONDUCTED TO IDENTIFY DIFFERENTIALLY EXPRESSED CIRCRNAS IN GINGIVAL TISSUES FROM PERIODONTITIS PATIENTS. THE RELATIONSHIP BETWEEN UPREGULATED CIRCRNAS EXPRESSION AND PROBING DEPTH (PD) WAS PERFORMED USING SPEARMAN'S CORRELATION ANALYSIS. BIOINFORMATIC ANALYSES INCLUDING GO ANALYSIS, CIRCRNA-DISEASE ASSOCIATION PREDICTION, AND CIRCRNA-MIRNA-MRNA NETWORK PREDICTION WERE PERFORMED TO CLARIFY POTENTIAL REGULATORY FUNCTIONS OF IDENTIFIED CIRCRNAS IN PERIODONTITIS. A RECEIVER-OPERATING CHARACTERISTIC (ROC) CURVE WAS ESTABLISHED TO ASSESS THE DIAGNOSTIC SIGNIFICANCE OF IDENTIFIED CIRCRNAS. RESULTS: HIGH-THROUGHPUT SEQUENCING IDENTIFIED 70 DIFFERENTIALLY EXPRESSED CIRCRNAS (68 UPREGULATED AND 2 DOWNREGULATED CIRCRNAS) IN HUMAN PERIODONTITIS (FOLD CHANGE >2.0 AND P < .05). THE TOP FIVE UPREGULATED CIRCRNAS WERE VALIDATED BY RT-QPCR THAT HAD STRONG ASSOCIATIONS WITH MULTIPLE HUMAN DISEASES, INCLUDING PERIODONTITIS. THE UPREGULATION OF CIRCRNAS WERE POSITIVELY CORRELATED WITH PD (R = .40-.69, P < .05, MODERATE). A CIRCRNA-MIRNA-MRNA NETWORK WITH THE TOP FIVE UPREGULATED CIRCRNAS, DIFFERENTIALLY EXPRESSED MRNAS, AND OVERLAPPED PREDICTED MIRNAS INDICATED POTENTIAL ROLES OF CIRCRNAS IN IMMUNE RESPONSE, CELL APOPTOSIS, MIGRATION, ADHESION, AND REACTION TO OXIDATIVE STRESS. THE ROC CURVE SHOWED THAT CIRCRNAS HAD POTENTIAL VALUE IN PERIODONTITIS DIAGNOSIS (AUC = 0.7321-0.8667, P < .05). CONCLUSION: CIRCRNA-DISEASE ASSOCIATIONS WERE PREDICTED BY ONLINE BIOINFORMATIC TOOLS. POSITIVE CORRELATION BETWEEN UPREGULATED CIRCRNAS, CIRCPTP4A2, CHR22:23101560-23135351+, CIRCARHGEF28, CIRCBARD1 AND CIRCRASA2, AND PD SUGGESTED FUNCTION OF CIRCRNAS IN PERIODONTITIS. NETWORK PREDICTION FURTHER FOCUSED ON DOWNSTREAM TARGETS REGULATED BY CIRCRNAS DURING PERIODONTITIS PATHOGENESIS.	2022	

3  5120  42 POSSIBLE EPIGENETIC REGULATORY EFFECT OF DYSREGULATED CIRCULAR RNAS IN EPILEPSY. CIRCULAR RNAS (CIRCRNAS) INVOLVE IN THE EPIGENETIC REGULATION AND ITS MAJOR MECHANISM IS THE SEQUESTRATION OF THE TARGET MICRO RNAS (MIRNAS). WE HYPOTHESIZED THAT CIRCRNAS MIGHT BE RELATED WITH THE PATHOPHYSIOLOGY OF CHRONIC EPILEPSY AND EVALUATED THE ALTERED CIRCRNA EXPRESSIONS AND THEIR POSSIBLE REGULATORY EFFECTS ON THEIR TARGET MIRNAS AND MRNAS IN A MOUSE EPILEPSY MODEL. THE CIRCRNA EXPRESSION PROFILE IN THE HIPPOCAMPUS OF THE PILOCARPINE MICE WAS ANALYZED AND COMPARED WITH CONTROL. THE CORRELATION BETWEEN THE EXPRESSION OF MIRNA BINDING SITES (MIRNA RESPONSE ELEMENTS, MRE) IN THE DYSREGULATED CIRCRNAS AND THE EXPRESSION OF THEIR TARGET MIRNAS WAS EVALUATED. AS MIRNAS ALSO INHIBIT THEIR TARGET MRNAS, CIRCRNA-MIRNA-MRNA REGULATORY NETWORK, COMPRISED OF DYSREGULATED RNAS THAT TARGETS ONE ANOTHER WERE SEARCHED. FOR THE IDENTIFIED NETWORKS, BIOINFORMATICS ANALYSES WERE PERFORMED. AS THE RESULT, FORTY-THREE CIRCRNAS WERE DYSREGULATED IN THE HIPPOCAMPUS (UP-REGULATED, 26; DOWN-REGULATED, 17). THE CHANGE IN THE EXPRESSION OF MRE IN THOSE CIRCRNAS NEGATIVELY CORRELATED WITH THE CHANGE IN THE RELEVANT TARGET MIRNA EXPRESSION (R = -0.461, P<0.001), SUPPORTING THAT CIRCRNAS INHIBIT THEIR TARGET MIRNA. 333 DYSREGULATED CIRCRNA-MIRNA-MRNA NETWORKS WERE IDENTIFIED. GENE ONTOLOGY AND PATHWAY ANALYSES DEMONSTRATED THAT THE UP-REGULATED MRNAS IN THOSE NETWORKS WERE CLOSELY RELATED TO THE MAJOR PROCESSES IN EPILEPSY. AMONG THEM, STRING ANALYSIS IDENTIFIED 37 KEY MRNAS WITH ABUNDANT (>/=4) INTERACTIONS WITH OTHER DYSREGULATED TARGET MRNAS. THE DYSREGULATION OF THE CIRCRNAS WHICH HAD MULTIPLE INTERACTIONS WITH KEY MRNAS WERE VALIDATED BY PCR. WE CONCLUDED THAT DYSREGULATED CIRCRNAS MIGHT HAVE A PATHOPHYSIOLOGIC ROLE IN CHRONIC EPILEPSY BY REGULATING MULTIPLE DISEASE RELEVANT MRNAS VIA CIRCRNA-MIRNA-MRNA INTERACTIONS.	2018	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                     
4  5495  33 REVIEW ON CIRCULAR RNAS AND NEW INSIGHTS INTO THEIR ROLES IN CANCER. CIRCULAR RNAS (CIRCRNAS) ARE A VERY INTERESTING CLASS OF CONSERVED SINGLE-STRANDED RNA MOLECULES DERIVED FROM EXONIC OR INTRONIC SEQUENCES BY PRECURSOR MRNA BACK-SPLICING. UNLIKE CANONICAL LINEAR RNAS, CIRCRNAS FORM COVALENTLY CLOSED, CONTINUOUS STABLE LOOPS WITHOUT A 5'END CAP AND 3'END POLY(A) TAIL, AND THEREFORE ARE RESISTANT TO EXONUCLEASE DIGESTION. THE MAJORITY OF CIRCRNAS ARE HIGHLY ABUNDANT, AND CONSERVED ACROSS DIFFERENT SPECIES WITH A TISSUE OR DEVELOPMENTAL-STAGE-SPECIFIC EXPRESSION. CIRCRNAS HAVE BEEN SHOWN TO PLAY IMPORTANT ROLES AS MICRORNA SPONGES, REGULATORS OF GENE SPLICING AND TRANSCRIPTION, RNA-BINDING PROTEIN SPONGES AND PROTEIN/PEPTIDE TRANSLATORS. EMERGING EVIDENCE REVEALS THAT CIRCRNAS FUNCTION IN VARIOUS HUMAN DISEASES, PARTICULARLY CANCERS, AND MAY FUNCTION AS BETTER PREDICTIVE BIOMARKERS AND THERAPEUTIC TARGETS FOR CANCER TREATMENT. IN CONSIDERATION OF THEIR POTENTIAL CLINICAL RELEVANCE, CIRCRNAS HAVE BECOME A NEW RESEARCH HOTSPOT IN THE FIELD OF TUMOR PATHOLOGY. IN THE PRESENT STUDY, THE CURRENT UNDERSTANDING OF THE BIOGENESIS, CHARACTERISTICS, DATABASES, RESEARCH METHODS, BIOLOGICAL FUNCTIONS SUBCELLULAR DISTRIBUTION, EPIGENETIC REGULATION, EXTRACELLULAR TRANSPORT AND DEGRADATION OF CIRCRNAS WAS DISCUSSED. IN PARTICULAR, THE MULTIPLE DATABASES AND METHODS INVOLVED IN CIRCRNA RESEARCH WERE FIRST SUMMARIZED, AND THE RECENT ADVANCES IN DETERMINING THE POTENTIAL ROLES OF CIRCRNAS IN TUMOR GROWTH, MIGRATION AND INVASION, WHICH RENDER CIRCRNAS BETTER PREDICTIVE BIOMARKERS, WERE DESCRIBED. FURTHERMORE, FUTURE PERSPECTIVES FOR THE CLINICAL APPLICATION OF CIRCRNAS IN THE MANAGEMENT OF PATIENTS WITH CANCER WERE PROPOSED, WHICH COULD PROVIDE NEW INSIGHTS INTO CIRCRNAS IN THE FUTURE.	2021	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                         
5  4297  33 MICRORNA-1224 SPLICING CIRCULARRNA-FILIP1L IN AN AGO2-DEPENDENT MANNER REGULATES CHRONIC INFLAMMATORY PAIN VIA TARGETING UBR5. DYSFUNCTIONS OF GENE TRANSCRIPTION AND TRANSLATION IN THE NOCICEPTIVE PATHWAYS PLAY THE CRITICAL ROLE IN DEVELOPMENT AND MAINTENANCE OF CHRONIC PAIN. CIRCULAR RNAS (CIRCRNAS) ARE EMERGING AS NEW PLAYERS IN REGULATION OF GENE EXPRESSION, BUT WHETHER AND HOW CIRCRNAS ARE INVOLVED IN CHRONIC PAIN REMAIN ELUSIVE. WE SHOWED HERE THAT COMPLETE FREUND'S ADJUVANT-INDUCED CHRONIC INFLAMMATION PAIN SIGNIFICANTLY INCREASED CIRCRNA-FILIP1L (FILAMIN A INTERACTING PROTEIN 1-LIKE) EXPRESSION IN SPINAL NEURONS OF MICE. BLOCKAGE OF THIS INCREASE ATTENUATED COMPLETE FREUND'S ADJUVANT-INDUCED NOCICEPTIVE BEHAVIORS, AND OVEREXPRESSION OF SPINAL CIRCRNA-FILIP1L IN NAIVE MICE MIMICKED THE NOCICEPTIVE BEHAVIORS AS EVIDENCED BY DECREASED THERMAL AND MECHANICAL NOCICEPTIVE THRESHOLD. FURTHERMORE, WE FOUND THAT MATURE CIRCRNA-FILIP1L EXPRESSION WAS NEGATIVELY REGULATED BY MIRNA-1224 VIA BINDING AND SPLICING OF PRECURSOR OF CIRCRNA-FILIP1L (PRE-CIRCRNA-FILIP1L) IN THE ARGONAUTE-2 (AGO2)-DEPENDENT MANNER. INCREASE OF SPINAL CIRCRNA-FILIP1L EXPRESSION RESULTED FROM THE DECREASE OF MIRNA-1224 EXPRESSION UNDER CHRONIC INFLAMMATION PAIN STATE. MIRNA-1224 KNOCKDOWN OR AGO2 OVEREXPRESSION INDUCED NOCICEPTIVE BEHAVIORS IN NAIVE MICE, WHICH WAS PREVENTED BY THE KNOCKDOWN OF SPINAL CIRCRNA-FILIP1L. FINALLY, WE DEMONSTRATED THAT A UBIQUITIN PROTEIN LIGASE E3 COMPONENT N-RECOGNIN 5 (UBR5), VALIDATED AS A TARGET OF CIRCRNA-FILIP1L, PLAYS A PIVOTAL ROLE IN REGULATION OF NOCICEPTION BY SPINAL CIRCRNA-FILIP1L. THESE DATA SUGGEST THAT MIRNA-1224-MEDIATED AND AGO2-DEPENDENT MODULATION OF SPINAL CIRCRNA-FILIP1L EXPRESSION REGULATES NOCICEPTION VIA TARGETING UBR5, REVEALING A NOVEL EPIGENETIC MECHANISM OF INTERACTION BETWEEN MIRNA AND CIRCRNA IN CHRONIC INFLAMMATION PAIN.SIGNIFICANCE STATEMENT CIRCRNAS ARE EMERGING AS NEW PLAYERS IN REGULATION OF GENE EXPRESSION. HERE, WE FOUND THAT THE INCREASE OF CIRCRNA-FILIP1L MEDIATED BY MIRNA-1224 IN AN AGO2-DEPENDENT WAY IN THE SPINAL CORD IS INVOLVED IN REGULATION OF NOCICEPTION VIA TARGETING UBR5 OUR STUDY REVEALS A NOVEL EPIGENETIC MECHANISM OF INTERACTION BETWEEN MIRNA AND CIRCRNA IN CHRONIC INFLAMMATION PAIN.	2019	
                                                                                                                                                                                                                                                                                                                                                              
6  1021  31 CIRCULAR RNA AS AN EPIGENETIC REGULATOR IN CHRONIC LIVER DISEASES. CIRCULAR RNA (CIRCRNA) IS A TYPE OF NON-CODING RNA CHARACTERIZED BY A COVALENTLY CLOSED CONTINUOUS LOOP. CIRCRNA IS GENERATED BY PRE-MRNA THROUGH BACK-SPLICING AND IS PROBABLY CLEARED UP BY EXTRACELLULAR VESICLES. CIRCRNAS PLAY A PIVOTAL ROLE IN THE EPIGENETIC REGULATION OF GENE EXPRESSION AT TRANSCRIPTIONAL AND POST-TRANSCRIPTIONAL LEVELS. RECENTLY, CIRCRNAS HAVE BEEN DEMONSTRATED TO BE INVOLVED IN THE REGULATION OF LIVER HOMEOSTASIS AND DISEASES. HOWEVER, THE EPIGENETIC ROLE AND UNDERLYING MECHANISMS OF CIRCRNAS IN CHRONIC LIVER DISEASES REMAIN UNCLEAR. THIS REVIEW DISCUSSED THE ROLE OF CIRCRNAS IN NON-NEOPLASTIC CHRONIC LIVER DISEASES, INCLUDING ALCOHOLIC LIVER DISEASE (ALD), METABOLIC-ASSOCIATED FATTY LIVER DISEASE (MAFLD), VIRAL HEPATITIS, LIVER INJURY AND REGENERATION, LIVER CIRRHOSIS, AND AUTOIMMUNE LIVER DISEASE. THE REVIEW ALSO HIGHLIGHTED THAT FURTHER EFFORTS ARE URGENTLY NEEDED TO DEVELOP CIRCRNAS AS NOVEL DIAGNOSTICS AND THERAPEUTICS FOR CHRONIC LIVER DISEASES.	2021	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                
7  3752  33 INTEGRATED ANALYSIS OF CIRCRNAS AND MRNAS EXPRESSION PROFILE REVEALED THE INVOLVEMENT OF HSA_CIRC_0007919 IN THE PATHOGENESIS OF ULCERATIVE COLITIS. BACKGROUND: ULCERATIVE COLITIS (UC) IS CHARACTERIZED BY CHRONIC INFLAMMATION IN THE COLON AND EPIGENETIC FACTORS UNDERLYING THE OCCURRENCE. CIRCULAR RNAS (CIRCRNAS) HAVE BEEN UNDER INTENSIVE FOCUS DUE TO THE CIRCULAR CONSTRUCT AND GENE-REGULATING FUNCTIONS. HOWEVER, THE CHANGES AND ROLES OF CIRCRNAS IN UC REMAIN UNKNOWN. METHODS: MICROARRAYS WERE USED TO DETECT THE DIFFERENTIALLY EXPRESSED GENES, AND QUANTITATIVE REAL-TIME PCR WAS USED TO IDENTIFY THE CHANGES IN UC. IN SILICO ANALYSES WERE PERFORMED TO PREDICT THE FUNCTIONS OF CIRCRNAS AND MRNAS. IN VITRO, EPITHELIAL CELL LINES WERE STIMULATED BY PRO-INFLAMMATION EFFECTORS TO TEST THE ALTERATIONS IN CIRCRNAS. CIRCRNAS-MICRORNAS-MRNAS NETWORK CLARIFIED THE POTENTIAL MECHANISMS UNDERLYING CIRCRNAS IN UC. THE BINDING SITE BETWEEN HSA_CIRC_0007919 AND MIR-138 OR LET-7A WAS VERIFIED USING DUAL-LUCIFERASE ASSAY. RESULTS: A TOTAL OF 264 SIGNIFICANTLY DYSREGULATED CIRCRNAS AND 1869 DIFFERENTIALLY EXPRESSED MRNAS IN INFLAMED MUCOSA WERE COMPARED WITH THE NON-INFLAMED MUCOSA IN UC. HSA_CIRC_0004662 AND HSA_CIRC_0007919 WERE ALTERED LARGELY IN UC TISSUES. HSA_CIRC_0007919 WAS REDUCED PERSISTENTLY AFTER INFLAMMATORY TREATMENTS, AND IT WAS RELEVANT TO MAYO ENDOSCOPIC SUBSCORES AND THE EXPRESSION OF TIGHT JUNCTION MOLECULES. FINALLY, HSA_CIRC_0007919 COULD HARBOR MIR-138, AND LET-7A TO REGULATE THE TARGETED MRNAS EPC1 AND VIPR1. CONCLUSIONS: SEVERAL CIRCRNAS WERE DIFFERENTIALLY EXPRESSED IN UC. HSA_CIRC_0007919 IS RELATED TO CLINICAL CHARACTERISTICS AND EPITHELIAL INTEGRITY BY BINDING TO HSA-LET-7A, HSA-MIR-138 TO REGULATE THE TARGET GENES. CIRCRNAS, ESPECIALLY HSA_CIRC_0007919, ARE ASSOCIATED WITH THE PATHOGENESIS AND DEVELOPMENT OF UC, WITH POTENTIAL DIAGNOSTIC AND THERAPEUTIC IMPLICATIONS.	2019	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                           
8  1022  41 CIRCULAR RNA HSA_CIRC_0098181 INHIBITS METASTASIS IN HEPATOCELLULAR CARCINOMA BY ACTIVATING THE HIPPO SIGNALING PATHWAY VIA INTERACTION WITH EEF2. INTRODUCTION AND OBJECTIVES: THE DEVELOPMENT OF HEPATOCELLULAR CARCINOMA (HCC) IS A MULTI-STEP PROCESS THAT ACCUMULATES GENETIC AND EPIGENETIC ALTERATIONS, INCLUDING CHANGES IN CIRCULAR RNA (CIRCRNA). THIS STUDY AIMED TO UNDERSTAND THE ALTERATIONS IN CIRCRNA EXPRESSION IN HCC DEVELOPMENT AND METASTASIS AND TO EXPLORE THE BIOLOGICAL FUNCTIONS OF CIRCRNA. MATERIALS AND METHODS: TEN PAIRS OF ADJACENT CHRONIC HEPATITIS TISSUES AND HCC TISSUES FROM PATIENTS WITHOUT VENOUS METASTASES, AND TEN HCC TISSUES FROM PATIENTS WITH VENOUS METASTASES WERE ANALYZED USING HUMAN CIRCRNA MICROARRAYS. DIFFERENTIALLY EXPRESSED CIRCRNAS WERE THEN VALIDATED BY QUANTITATIVE REAL-TIME PCR. IN VITRO AND IN VIVO ASSAYS WERE PERFORMED TO ASSESS THE ROLES OF THE CIRCRNA IN HCC PROGRESSION. RNA PULL-DOWN ASSAY, MASS SPECTROMETRY ANALYSIS, AND RNA-BINDING PROTEIN IMMUNOPRECIPITATION WERE CONDUCTED TO EXPLORE THE PROTEIN PARTNERS OF THE CIRCRNA. RESULTS: CIRCRNA MICROARRAYS REVEALED THAT THE EXPRESSION PATTERNS OF CIRCRNAS ACROSS THE THREE GROUPS WERE SIGNIFICANTLY DIFFERENT. AMONG THESE, HSA_CIRC_0098181 WAS VALIDATED TO BE LOWLY EXPRESSED AND ASSOCIATED WITH POOR PROGNOSIS IN HCC PATIENTS. ECTOPIC EXPRESSION OF HSA_CIRC_0098181 DELAYED HCC METASTASIS IN VITRO AND IN VIVO. MECHANISTICALLY, HSA_CIRC_0098181 SEQUESTERED EUKARYOTIC TRANSLATION ELONGATION FACTOR 2 (EEF2) AND DISSOCIATED EEF2 FROM FILAMENTOUS ACTIN (F-ACTIN) TO PREVENT F-ACTIN FORMATION, WHICH BLOCKED ACTIVATION OF THE HIPPO SIGNALING PATHWAY. IN ADDITION, THE RNA BINDING PROTEIN QUAKING-5 BOUND DIRECTLY TO HSA_CIRC_0098181 AND INDUCED ITS BIOGENESIS. CONCLUSIONS: OUR STUDY REVEALS CHANGES IN CIRCRNA EXPRESSION FROM CHRONIC HEPATITIS, PRIMARY HCC, TO METASTATIC HCC. FURTHER, THE QKI5-HSA_CIRC_0098181-EEF2-HIPPO SIGNALING PATHWAY EXERTS A REGULATORY ROLE IN HCC.	2023	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                             
9   885  43 CHRONIC CONSTRICTION INJURY-INDUCED CHANGES IN CIRCULAR RNA EXPRESSION PROFILING OF THE DORSAL ROOT GANGLION IN A RAT MODEL OF NEUROPATHIC PAIN. BACKGROUND: THE PATHOGENESIS OF NEUROPATHIC PAIN (NP) HAS NOT BEEN FULLY ELUCIDATED. GENE CHANGES IN DORSAL ROOT GANGLIA (DRG) MAY CONTRIBUTE TO THE DEVELOPMENT OF NP. CIRCULAR RNAS (CIRCRNAS) ARE A CLASS OF ENDOGENOUS NONCODING RNAS THAT FORM COVALENTLY CLOSED LOOP STRUCTURES AND ARE CRUCIAL FOR GENETIC AND EPIGENETIC REGULATION. HOWEVER, LITTLE IS KNOWN ABOUT CIRCRNA CHANGES IN DRG NEURONS AFTER PERIPHERAL NERVE INJURY. METHODS: A SCIATIC NERVE CHRONIC CONSTRICTION INJURY (CCI) MODEL WAS ESTABLISHED TO INDUCE NEUROPATHIC PAIN. WE PERFORMED GENOME-WIDE CIRCRNA ANALYSIS OF FOUR PAIRED DORSAL ROOT GANGLION (DRG) SAMPLES (L4-L5) FROM CCI AND NEGATIVE CONTROL (NC) RATS USING NEXT-GENERATION SEQUENCING TECHNOLOGY. THE DIFFERENTIALLY EXPRESSED CIRCRNAS (DECIRCRNAS) WERE IDENTIFIED BY DIFFERENTIAL EXPRESSION ANALYSIS, AND THE EXPRESSION PROFILE OF CIRCRNAS WAS VALIDATED BY QUANTITATIVE PCR. GENE ONTOLOGY AND KYOTO ENCYCLOPEDIA OF GENES AND GENOMES ANALYSES WERE PERFORMED TO PREDICT THE FUNCTION OF DECIRCRNAS. RESULTS: A TOTAL OF 374 DECIRCRNAS WERE IDENTIFIED BETWEEN CCI AND NC RATS USING CIRCRNA HIGH-THROUGHPUT SEQUENCING. AMONG THEM, 290 WERE UPREGULATED AND 84 WERE DOWNREGULATED IN THE CCI GROUP. THE EXPRESSION LEVELS OF NINE DECIRCRNAS WERE VALIDATED BY QPCR. FUNCTIONAL ANNOTATION ANALYSIS SHOWED THAT THE DECIRCRNAS WERE MAINLY ENRICHED IN PATHWAYS AND FUNCTIONS, INCLUDING 'DOPAMINERGIC SYNAPSE,' 'RENIN SECRETION,' 'MITOGEN-ACTIVATED PROTEIN KINASE SIGNALING PATHWAY,' AND 'NEUROGENESIS.' COMPETING ENDOGENOUS RNA ANALYSIS SHOWED THAT THE TOP 50 CIRCRNAS EXHIBITED INTERACTIONS WITH FOUR PAIN-RELATED MICRORNAS (MIRNAS). CIRC:CHR2:33950934-33955969 WAS THE LARGEST NODE IN THE CIRCRNA-MIRNA INTERACTION NETWORK. CONCLUSIONS: PERIPHERAL NERVE INJURY-INDUCED NEUROPATHIC PAIN LED TO CHANGES IN THE COMPREHENSIVE EXPRESSION PROFILE OF CIRCRNAS IN THE DRG OF RATS. DECIRCRNAS MAY ADVANCE OUR UNDERSTANDING OF THE MOLECULAR MECHANISMS UNDERLYING NEUROPATHIC PAIN.	2022	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                 
10  1019  28 CIRCRNA-MIRNA CROSS-TALK IN THE TRANSITION FROM PAROXYSMAL TO PERMANENT ATRIAL FIBRILLATION. BACKGROUND: ATRIAL FIBRILLATION (AF) IS THE MOST PREVALENT CARDIAC ARRHYTHMIA IN WESTERN COUNTRIES. THE FACTORS GOVERNING THE PROGRESSION OF AF TO A PERMANENT CHRONIC CONDITION ARE STILL NOT WELL CHARACTERIZED. AMONG EPIGENETIC FACTORS, NON-CODING RNAS (NCRNAS) SUCH AS MIRNAS AND LNCRNAS HAVE BEEN RECENTLY DESCRIBED AS IMPORTANT PLAYERS INVOLVED IN THE AF PROGRESSION. WE HYPOTHESIZE ABOUT THE EXISTENCE OF ADDITIONAL REGULATORY LAYERS IN AF INVOLVING AN INTRICATE CROSS-TALK BETWEEN DIFFERENT NCRNA SPECIES, NAMELY MIRNAS AND CIRCRNAS FOR THE ESTABLISHMENT OF A CHRONIC AF CONDITION. METHODS AND RESULTS: WE HAVE PERFORMED AN UNBIASED STUDY ANALYZING THE EXPRESSION PROFILE FOR MIRNAS AND CIRCRNAS IN LEFT-ATRIAL BIOPSIES FROM PATIENTS WITH PAROXYSMAL AND PERMANENT AF BY RNA-SEQ. THE TRANSITION FROM PAROXYSMAL TO PERMANENT AF IS CHARACTERIZED BY A PATTERN OF DOWN-REGULATED MIRNAS, CONCOMITANT TO THE APPEARANCE OF SPECIFIC CIRCRNA SPECIES. THE ANALYSIS OF THE SPONGING ACTIVITIES OF THE CIRCRNAS EXCLUSIVELY EXPRESSED IN PERMANENT AF SAMPLES, ALLOWED US TO DETERMINE THAT THEY COULD BE RESPONSIBLE FOR THE DOWNREGULATION OF SPECIFIC MIRNAS IN ESTABLISHMENT OF A PERMANENT AF CONDITION. CONCLUSION: SPONGING ACTIVITY OF CIRCRNAS SEQUESTERING SPECIFIC MIRNAS IS AN IMPORTANT FACTOR TO BE CONSIDERED FOR THE DETERMINATION OF THE MOLECULAR MECHANISMS INVOLVED IN AF PROGRESSION.	2019	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                            
11  1131  44 COMPREHENSIVE CIRCULAR RNA EXPRESSION PROFILING WITH ASSOCIATED CERNA NETWORK REVEALS THEIR THERAPEUTIC POTENTIAL IN CHOLESTEATOMA. CHOLESTEATOMA IS A CHRONIC DISEASE THAT PATHOLOGICALLY DISPLAYS A BENIGN TUMOR WITH EXCESSIVE SQUAMOUS EPITHELIAL CELL PROLIFERATION IN THE MIDDLE EAR. CLINICALLY, HOWEVER, IT CAN MANIFEST MALIGNANT BEHAVIOR BY DESTROYING ADJACENT TISSUES AND ORGANS. ALTHOUGH PREVIOUS STUDIES HAVE DEMONSTRATED THAT THE PATHOGENESIS OF CHOLESTEATOMA IS CORRELATED WITH EPIGENETIC DYSREGULATION, THE EXACT MECHANISM REMAINS UNCLEAR. CIRCULAR RNAS (CIRCRNAS) HAVE BEEN REVEALED AS BEING ABUNDANTLY EXPRESSED IN VARIOUS ORGANISMS AND HAVE BEEN FOUND TO CONTRIBUTE TO THE REGULATION OF MANY DISEASES. TO DATE, NO REPORTS HAVE ELUCIDATED THEIR EXPRESSION PROFILES AND FUNCTIONS IN CHOLESTEATOMA. IN THE PRESENT STUDY, THE CIRCRNA EXPRESSION PROFILE IN CHOLESTEATOMA WAS EXPLORED FOR THE FIRST TIME BY USING MICROARRAY ANALYSIS. WE OBTAINED A TOTAL OF 355 SIGNIFICANTLY DIFFERENTIALLY EXPRESSED CIRCRNAS IN CHOLESTEATOMA, AMONG WHICH 101 WERE IDENTIFIED TO BE UPREGULATED AND 254 DOWNREGULATED. BY CONSTRUCTING CIRCRNA?LNCRNA?MIRNA?MRNA COMPETING ENDOGENOUS RNA (CERNA) NETWORK, IT WAS DISCOVERED THAT CIRCRNAS MAY FUNCTION AS CERNAS AND CONTRIBUTE TO THE FORMATION OF CHOLESTEATOMA. THESE RESULTS PROVIDE NOVEL INSIGHT INTO THE PATHOGENESIS OF CHOLESTEATOMA AND SUGGEST CIRCRNAS AS POTENTIAL PROMISING THERAPEUTIC TARGETS FOR CHOLESTEATOMA.	2020	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                  
12  1020  26 CIRCRNAS IN ATHEROSCLEROSIS, WITH SPECIAL EMPHASIS ON THE SPONGY EFFECT OF CIRCRNAS ON MIRNAS. ATHEROSCLEROSIS (AS) IS A CHRONIC INFLAMMATORY DISEASE, WHICH LEADS TO ATHEROSCLEROTIC RUPTURE, LUMEN STENOSIS AND THROMBOSIS, AND OFTEN ENDANGERS LIFE. CIRCULAR RNAS (CIRCRNAS) ARE A SPECIAL CLASS OF NON-CODING RNA MOLECULES, WHOSE ABNORMAL EXPRESSION HAS BEEN PROVED TO BE CLOSELY RELATED TO HUMAN DISEASES, INCLUDING AS. BOTH THE ABNORMAL REGULATION OF CIRCRNAS AND THE SPONGING EFFECT ON MIRNAS WOULD LEAD TO CHANGES IN GENE EXPRESSION IN THE FORM OF EPIGENETIC MODIFICATION, ULTIMATELY LEADING TO THE FORMATION OF AS. CIRCRNAS CAN BE USED AS PERIPHERAL BLOOD MARKERS OF AS, AND PLAY AN IMPORTANT REGULATORY ROLE IN THE PROLIFERATION, MIGRATION, INFLAMMATION AND APOPTOSIS OF VASCULAR SMOOTH MUSCLE CELLS, ENDOTHELIAL CELLS AND MACROPHAGE, WHICH ARE KEY CELLS FOR THE DEVELOPMENT OF AS. THE IN-DEPTH UNDERSTANDING OF CIRCRNAS IN AS NOT ONLY PROVIDES A NEW METHOD FOR THE DIAGNOSIS OF AS, BUT ALSO PROVIDES A NEW IDEA FOR THE TREATMENT OF AS.	2023	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                             
13  6907  21 [THE ROLE OF THE CIRCULAR RNAS IN MULTIPLE SCLEROSIS AND OTHER NEUROIMMUNE DISORDERS]. IN RECENT YEARS NON-CODING RNAS HAVE RECEIVED INCREASING ATTENTION AS AN IMPORTANT EPIGENETIC MECHANISM, WITH PARTICULAR ROLE OF MICRO RNAS. AS THE REGULATION OF MIRNA EXPRESSION IS HIGHLY DYNAMIC AND COMPLEX, GROWING EVIDENCE SUGGESTS THE EXISTENCE OF ANOTHER HIGHER LEVEL OF REGULATORY MECHANISM INVOLVED IN MIRNA ACTIVITY - CIRCULAR RNAS (CIRCRNAS). CIRCRNAS REPRESENT NOVEL, UNIQUE CLASS OF ENDOGENOUS NCRNAS CONTROLLING THE EXPRESSION AND FUNCTION OF MIRNA. THEY ARE CALLED NATURAL MIRNA "SPONGES". ACCUMULATING EVIDENCE REVEALS CIRCRNAS ROLE IN PHYSIOLOGICAL AND PATHOLOGICAL PROCESSES INCLUDING CNS AND IMMUNE REGULATION. PREVIOUS STUDIES IMPLICATED MIRNAS IN REGULATION OF AUTOIMMUNE DEMYELINATION IN MS. MULTIPLE SCLEROSIS IS A CHRONIC NEUROLOGICAL INFLAMMATORY DEMYELINATING DISORDER OF THE CENTRAL NERVOUS SYSTEM. WHILE THE ETIOLOGY OF MS IS STILL NOT FULLY UNDERSTOOD, ACCUMULATING EVIDENCE SUGGESTS THAT IT IS A MULTIFACTORIAL ENTITY WITH SIGNIFICANT INVOLVEMENT OF AUTOIMMUNE PROCESSES.	2022	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                              
14  1727  31 DYSREGULATION OF LONG NON-CODING RNAS IN MOUSE MODELS OF LOCALIZATION-RELATED EPILEPSY. GENOME-WIDE PROFILING HAS REVEALED THAT EUKARYOTIC GENOMES ARE TRANSCRIBED INTO NUMEROUS NON-CODING RNAS. IN PARTICULAR, LONG NON-CODING RNAS (LNCRNAS) HAVE BEEN IMPLICATED IN VARIOUS HUMAN DISEASES DUE TO THEIR BIOCHEMICAL AND FUNCTIONAL DIVERSITY. EPILEPTIC DISORDERS HAVE BEEN CHARACTERIZED BY DYSREGULATION OF EPIGENETIC REGULATORY MECHANISMS, AND RECENT STUDIES HAVE IDENTIFIED SEVERAL LNCRNAS INVOLVED IN NEURAL DEVELOPMENT AND NETWORK FUNCTION. HOWEVER, COMPREHENSIVE PROFILING OF LNCRNAS IMPLICATED IN CHRONIC EPILEPSY HAS BEEN LACKING. IN THIS STUDY, MICROARRAY ANALYSIS WAS PERFORMED TO OBTAIN THE EXPRESSION PROFILE OF LNCRNAS DYSREGULATED IN PILOCARPINE AND KAINATE MODELS, TWO MODELS OF TEMPORAL LOBE EPILEPSY COMMONLY USED FOR STUDYING EPILEPTIC MECHANISMS. TOTAL OF 4622 LNCRNAS WERE ANALYZED: 384 LNCRNAS WERE SIGNIFICANTLY DYSREGULATED IN PILOCARPINE MODEL, AND 279 LNCRNAS WERE SIGNIFICANTLY DYSREGULATED IN KAINATE MODEL COMPARED WITH CONTROL MICE (>/=3.0-FOLD, P < 0.05). AMONG THESE, 54 AND 14 LNCRNAS, RESPECTIVELY, HAD ADJACENT PROTEIN-CODING GENES WHOSE EXPRESSIONS WERE ALSO SIGNIFICANTLY DYSREGULATED (>/=2.0-FOLD, P < 0.05). MAJORITY OF THESE PAIRS OF LNCRNAS AND ADJACENT GENES SHARED THE SAME DIRECTION OF DYSREGULATION. FOR THE SELECTED ADJACENT GENE-LNCRNA PAIRS, SIGNIFICANT GENE ONTOLOGY TERMS WERE EMBRYONIC APPENDAGE MORPHOGENESIS AND NEURON DIFFERENTIATION. THIS WAS THE FIRST STUDY TO COMPREHENSIVELY IDENTIFY DYSREGULATED LNCRNAS IN TWO DIFFERENT MODELS OF CHRONIC EPILEPSY AND WILL LIKELY PROVIDE A NOVEL INSIGHT INTO DEVELOPING LNCRNA THERAPEUTICS.	2015	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                 
15  1051  29 CLINICAL IMPLICATIONS OF EXOSOME-DERIVED NONCODING RNAS IN LIVER. EXOSOMES, ONE OF THREE MAIN TYPES OF EXTRACELLULAR VESICLES, ARE ~30-100 NM IN DIAMETER AND HAVE A LIPID BILAYER MEMBRANE. THEY ARE WIDELY DISTRIBUTED IN ALMOST ALL BODY FLUIDS. EXOSOMES HAVE THE POTENTIAL TO REGULATE UNKNOWN CELLULAR AND MOLECULAR MECHANISMS IN INTERCELLULAR COMMUNICATION, ORGAN HOMEOSTASIS, AND DISEASES. THEY ARE CRITICAL SIGNAL CARRIERS THAT TRANSFER NUCLEIC ACIDS, PROTEINS, LIPIDS, AND OTHER SUBSTANCES INTO RECIPIENT CELLS, PARTICIPATING IN CELLULAR SIGNAL TRANSDUCTION AND MATERIAL EXCHANGE. NCRNAS ARE NON-PROTEIN-CODING GENES THAT ACCOUNT FOR OVER 90% OF THE GENOME AND INCLUDE MICRORNAS (MIRNAS), LONG NCRNAS (LNCRNAS), AND CIRCULAR RNAS (CIRCRNAS). NCRNAS ARE CRUCIAL FOR PHYSIOLOGICAL AND PATHOLOGICAL ACTIVITIES IN THE LIVER BY PARTICIPATING IN GENE TRANSCRIPTION, POSTTRANSCRIPTIONAL EPIGENETIC REGULATION, AND CELLULAR PROCESSES THROUGH INTERACTING WITH DNA, RNA, OR PROTEINS. RECENT EVIDENCE FROM BOTH CLINICAL AND PRECLINICAL STUDIES INDICATES THAT EXOSOME-DERIVED NONCODING RNAS (NCRNAS) ARE HIGHLY INVOLVED IN THE PROGRESSION OF ACUTE AND CHRONIC LIVER DISEASES BY REGULATING HEPATIC LIPID METABOLISM, INNATE IMMUNITY, VIRAL INFECTION, FIBROSIS, AND CANCER. THEREFORE, EXOSOME-DERIVED NCRNAS HAVE PROMISING POTENTIAL AND CLINICAL IMPLICATIONS FOR THE EARLY DIAGNOSIS, TARGETED THERAPY, AND PROGNOSIS OF LIVER DISEASES.	2022	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                               
16  1718  28 DYSREGULATED LONG NON-CODING RNAS IN THE TEMPORAL LOBE EPILEPSY MOUSE MODEL. PURPOSE: TO PERFORM COMPREHENSIVE PROFILING OF LONG NON-CODING RNAS (LNCRNAS) IN TEMPORAL LOBE EPILEPSY. METHODS: WE PERFORMED EXTENSIVE PROFILING OF LNCRNAS AND MRNAS IN THE MOUSE PILOCARPINE MODEL IN SPECIFIC BRAIN REGIONS, THE HIPPOCAMPUS AND CORTEX, AND COMPARED THE RESULTS TO THOSE OF THE CONTROL MOUSE. DIFFERENTIALLY EXPRESSED LNCRNAS AND MRNAS WERE IDENTIFIED WITH A MICROARRAY ANALYSIS (ARRAYSTAR MOUSE LNCRNA EXPRESSION MICROARRAY V3.0). THEN, GENE ONTOLOGY (GO) AND PATHWAY ANALYSIS WERE PERFORMED TO INVESTIGATE THE POTENTIAL ROLES OF THE DIFFERENTIALLY EXPRESSED MRNAS IN THE PILOCARPINE MODEL. PROTEIN-PROTEIN INTERACTIONS TRANSCRIBED BY DYSREGULATED MRNAS WITH/WITHOUT CO-DYSREGULATED LNCRNAS WERE ANALYZED USING STRING V10 (HTTP://STRING-DB.ORG/). RESULTS: A TOTAL OF 22 AND 83 LNCRNAS WERE UP- AND DOWN-REGULATED (>/=2.0-FOLD, ALL P < .05), RESPECTIVELY, IN THE HIPPOCAMPUS OF THE EPILEPSY MODEL, WHILE 46 AND 659 LNCRNAS WERE UP- AND DOWN-REGULATED, RESPECTIVELY, IN THE CORTEX OF THE EPILEPSY MODEL. GO AND PATHWAY ANALYSIS REVEALED THAT THE DYSREGULATED MRNAS WERE CLOSELY ASSOCIATED WITH A PROCESS ALREADY KNOWN TO BE INVOLVED IN EPILEPTOGENESIS: ACUTE INFLAMMATION, CALCIUM ION REGULATION, EXTRACELLULAR MATRIX REMODELING, AND NEURONAL DIFFERENTIATION. AMONG THE LNCRNAS, WE IDENTIFIED 10 LNCRNAS COMMONLY DYSREGULATED WITH CORRESPONDING MRNAS IN THE CORTEX. THE STRING ANALYSIS SHOWED THAT THE DYSREGULATED MRNAS WERE INTERCONNECTED AROUND TWO CENTERS: THE MTOR PATHWAY-RELATED GENES AND REST PATHWAY-RELATED GENES. CONCLUSION: LNCRNAS WERE DYSREGULATED IN THE PILOCARPINE MOUSE MODEL ACCORDING TO THE BRAIN REGIONS OF THE HIPPOCAMPUS AND CORTEX. THE DYSREGULATED LNCRNAS WITH CO-DYSREGULATED MRNAS MIGHT BE POSSIBLE THERAPEUTIC TARGETS FOR THE EPIGENETIC REGULATION OF CHRONIC EPILEPSY.	2018

THE PRESENT STUDY INVESTIGATED THE EFFECT OF 0.5 MUG/ML GO-AGNPS FOR 10 WEEKS ON THE DIFFERENTIAL EXPRESSION OF CIRCULAR RNAS (CIRCRNAS) IN CAPRINE FETAL FIBROBLAST CELLS (CFFCS), AND THIS DOSE OF GO-AGNPS DID NOT AFFECT CELL VIABILITY AND ROS LEVEL. WE PREDICTED THE FUNCTIONS OF THOSE DIFFERENTIALLY EXPRESSED (DE) CIRCRNAS IN CFFCS BY BIOINFORMATICS ANALYSIS. FURTHERMORE, WE VALIDATED THE EXPRESSION OF TEN DE CIRCRNAS USING QUANTITATIVE REAL-TIME REVERSE TRANSCRIPTION-POLYMERASE CHAIN REACTION (QRT-PCR) TO ENSURE THE RELIABILITY OF THE SEQUENCING DATA. OUR RESULTS SHOWED THAT THE DE CIRCRNAS MAY POTENTIALLY REGULATE THE GO-AGNPS-INDUCING EPIGENETIC TOXICITY THROUGH A REGULATORY NETWORK CONSISTED OF CIRCRNAS, MIRNAS AND MESSENGER RNAS (MRNAS). THEREFORE, THE EPIGENETICS TOXICITY IS ESSENTIAL TO ASSESS THE BIOSAFETY LEVEL OF GO-AGNPS.	2023	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                          
18   263  20 ADVANCES WITH LONG NON-CODING RNAS IN DIABETIC PERIPHERAL NEUROPATHY. LONG NON-CODING RNAS (?LNCRNAS) ?ARE A GROUP OF NON-CODING RNAS LONGER THAN 200 NUCLEOTIDES, WHICH ARE DEFINED AS TRANSCRIPTS. THE LNCRNAS ARE INVOLVED IN REGULATING GENE EXPRESSION AT EPIGENETIC, TRANSCRIPTIONAL, AND POST-TRANSCRIPTIONAL LEVELS. RECENT STUDIES HAVE FOUND THAT LNCRNA IS CLOSELY RELATED TO MANY DISEASES LIKE NEUROLOGICAL DISEASES, ENDOCRINE AND METABOLIC DISORDERS. DIABETIC PERIPHERAL NEUROPATHY (DPN) IS ONE OF THE MOST COMMON CHRONIC COMPLICATIONS OF DIABETES MELLITUS. IN THIS REVIEW, WE HIGHLIGHT THE LATEST RESEARCH RELATED TO LNCRNAS IN DPN.	2020	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                 
19  1879  28 EMERGING ROLES OF NON-CODING RNAS IN PSORIASIS PATHOGENESIS. PSORIASIS IS A COMPLEX GENETIC SKIN DISORDER TYPICALLY MANIFESTED BY RED, SCALY, AND ITCHY PLAQUES MOST COMMONLY OVER THE SCALP, TRUNK, ELBOWS, AND KNEES. HISTOPATHOLOGICAL FEATURES INCLUDE THICKENING OF THE EPIDERMAL LAYER DUE TO HYPER-PROLIFERATION AND ABNORMAL DIFFERENTIATION OF EPIDERMAL KERATINOCYTES ALONG WITH INFILTRATION OF IMMUNE CELLS IN THE PSORIATIC SKIN. IT IS A CHRONIC INFLAMMATORY RELAPSING DISEASE, AND THERE IS CURRENTLY NO PERMANENT CURE FOR PSORIASIS. PROPER MEDICATIONS CAN REDUCE THE SEVERITY OF THE DISEASE AND IMPROVE THE QUALITY OF LIFE OF THE PATIENTS. WHILE THE GENETIC COMPONENTS OF PSORIASIS PATHOGENESIS ARE WELL EXPLORED, THE FULL UNDERSTANDING OF ITS EPIGENETIC COMPONENT REMAINS ELUSIVE. NON-CODING RNAS (NCRNAS) ARE DOCUMENTED TO REGULATE VARIOUS EPIGENETIC PROCESSES THAT LEAD TO THE PATHOGENESIS OF DIFFERENT DISEASES INCLUDING PSORIASIS. IN THIS REVIEW, WE HAVE DISCUSSED THE MOLECULAR INTERPLAY OF DIFFERENT NCRNAS IN PSORIASIS PATHOGENESIS. THE ROLES OF MICRORNAS (MIRNAS) IN PSORIASIS ARE PRETTY WELL STUDIED, WHEREAS THE ROLES OF LONG NONCODING RNAS (LNCRNAS) AND CIRCULAR RNAS (CIRCRNAS) ARE EMERGING. THIS REVIEW PROVIDES IDEAS COVERING SOME OF THE LATEST FINDINGS OF DIFFERENT MODES OF FUNCTIONS PLAYED BY THOSE DIFFERENT NCRNAS DOCUMENTED IN THE LITERATURE. AS AN EVER-EVOLVING TOPIC, SOME WORKS ARE STILL ONGOING AS WELL AS THERE ARE SEVERAL FIELDS THAT NEED RIGOROUS SCIENTIFIC VENTURES. WE HAVE PROPOSED THE AREAS WHICH CLAIM MORE EXPLORATIONS TO BETTER UNDERSTAND THE ROLES PLAYED BY THE NCRNAS IN PSORIASIS PATHOGENESIS.	2023	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                            
20  5777  27 SPINAL CIRCKCNK9 REGULATES CHRONIC VISCERAL HYPERSENSITIVITY OF IRRITABLE BOWEL SYNDROME. DYSREGULATION OF CIRCULAR RNAS (CIRCRNAS) HAS BEEN REPORTED TO BE FUNCTIONALLY ASSOCIATED WITH CHRONIC PAIN, BUT IT IS UNKNOWN WHETHER AND HOW CIRCRNAS PARTICIPATE IN VISCERAL HYPERSENSITIVITY. THE EXPRESSION OF CIRCKCNK9 WAS INCREASED IN SPINAL NEURONS OF IRRITABLE BOWEL SYNDROME (IBS)-LIKE RATS. SHCIRCKCNK9 ATTENUATED VISCERAL HYPERSENSITIVITY AND INHIBITED C-FOS EXPRESSION IN IBS-LIKE RATS, WHEREAS OVEREXPRESSION OF SPINAL CIRCKCNK9 INDUCED VISCERAL HYPERSENSITIVITY AND INCREASED C-FOS EXPRESSION IN CONTROL RATS. FURTHERMORE, CIRCKCNK9 WAS FOUND TO ACT AS A MIR-124-3P SPONGE. MIR-124-3P ANTAGOMIR RESTORED PAIN RESPONSES DOWNREGULATED BY SHCIRCKCNK9 IN IBS-LIKE RATS. FINALLY, THE SIGNAL TRANSDUCER AND ACTIVATOR OF TRANSCRIPTION 3 (STAT3), VALIDATED AS A TARGET OF MIR-124-3P, COULD PLAY A CRITICAL ROLE IN VISCERAL HYPERSENSITIVITY BY REGULATING NSF/GLUR2. PERSPECTIVE: SPINAL CIRCKCNK9 FUNCTIONS AS A MIR-124-3P SPONGE TO PROMOTE VISCERAL HYPERSENSITIVITY BY REGULATING THE STAT3/NSF/GLUR2 PATHWAY. THIS PATHWAY MIGHT PROVIDE A NOVEL EPIGENETIC MECHANISM OF VISCERAL HYPERSENSITIVITY AND A POTENTIAL CIRCRNA THERAPEUTIC TARGET FOR IBS.	2023
