| 1 | Daily genetic profiling indicates JAK/STAT signaling promotes early hepatic stellate cell transdifferentiation显示文摘AIM: To identify signaling pathways and genes that initiate and commit hepatic stellate cells (HSCs) to transdifferentiation. METHODS: Primary HSCs were isolated from male Sprague-Dawley rats and cultured on plastic for 0-10 d. Gene expression was assessed daily (quiescent to day 10 culture-activation) by real time polymerase chain reaction and data clustered using AMADA software. The significance of JAK/STAT signaling to HSC transdifferentiation was determined by treating cells with a JAK2 inhibitor. RESULTS: Genetic cluster analyses, based on expression of these 21 genes, showed similar expression profiles on days 1-3, days 5 and 6, and days 7-10, while freshly isolated cells (day Q) and day 4 cells were genotypically distinct from any of the other days. Additionally, gene expression clustering revealed strong upregulation of interleukin-6, JAK2 and STAT3 mRNA in the early stages of activation. Inhibition of the JAK/STAT signaling pathway impeded the morphological transdifferentiation of HSCs which correlated with decreased mRNA expression of several profibrotic genes including collagens, α-SMA, PDGFR and TGFβR. CONCLUSION: These data demonstrate unique clustered genetic profiles during the daily progression of HSC transdifferentiation and that JAK/STAT signaling may be critical in the early stages of transdifferentiation. | Ashley M Lakner Cathy C Moore Alyssa A Gulledge Laura W Schrum | 2010 | World Journal of Gastroenterology2010，16，40： | 23 |
| 2 | Is rectal indomethacin effective in preventing of post-endoscopic retrograde cholangiopancreatography pancreatitis?显示文摘AIM:To investigate the effectiveness of rectally administered indomethacin in the prophylaxis of post-endoscopic retrograde cholangiopancreatography(ERCP)pancreatitis and hyperamylasaemia in a multicentre study.METHODS:A prospective,randomised,placebocontrolled multicentre study in five endoscopic units was conducted on 686 patients randomised to receive a suppository containing 100 mg indomethacin,or an inert placebo,10-15 min before ERCP.Post-ERCP pancreatitis and hyperamylasaemia were evaluated 24 h following the procedure on the basis of clinical signs and laboratory parameters,and computed tomography/magnetic resonance imaging findings if required.RESULTS:Twenty-one patients were excluded because of incompleteness of their data or because of protocol violation.The results of 665 investigations were evaluated:347 in the indomethacin group and 318 in the placebo group.The distributions of the risk factors in the two groups did not differ significantly.Pancreatitis developed in 42 patients(6.3%):it was mild in34(5.1%)and severe in eight(1.2%)cases.Hyperamylaesemia occurred in 160 patients(24.1%).There was no significant difference between the indomethacin and placebo groups in the incidence of either postERCP pancreatitis(5.8%vs 6.9%)or hyperamylasaemia(23.3%vs 24.8%).Similarly,subgroup analysis did not reveal any significant differences between the two groups.CONCLUSION:100 mg rectal indomethacin administered before ERCP did not prove effective in preventing post-ERCP pancreatitis. | Zoltán Dbrnte Zoltán Szepes Ferenc Izbéki Judit Gervain László Lakatos Gyula Pécsi Miklós Ihász Lilla Lakner Erzsébet Toldy László Czakó | 2014 | World Journal of Gastroenterology2014，20，29： | 16 |
| 3 | microRNAs: Fad or future of liver disease显示文摘microRNAs (miRs) are small non-coding RNAs that regulate both mRNA and protein expression of target genes, which results in alterations in mRNA stability or translation inhibition. miRs influence at least one third of all human transcripts and are known regulators of various important cellular growth and differentiation factors. miRs have recently emerged as key regulatory molecules in chronic liver disease. This review details recent contributions to the field of miRs that influence liver development and the broad spectrum of disease, from non-alcoholic fatty liver disease to fibrosis/cirrhosis, with particular emphasis on hepatic stellate cells and potential use of miRs as therapeutic tools. | Ashley M Lakner Herbert L Bonkovsky Laura W Schrum | 2011 | World Journal of Gastroenterology2011，17，20： | 13 |

| 5 | Interaction of the major inflammatory bowel disease susceptibility alleles in Crohn’s disease patients显示文摘AIM:To investigate the interaction of interleukin-23 receptor(IL23R)(rs1004819 and rs2201841),autophagy-related 16-like 1(ATG16L1)(rs2241880), caspase recruitment domain-containing protein 15 (CARD15)genes,and IBD5 locus in Crohn's disease(CD) patients. METHODS:A total of 315 unrelated subjects with CD and 314 healthy controls were genotyped.Interactions and specific genotype combinations of a total of eight variants were tested.The variants of IBD5locus(IGR2198a_1 rs11739135 and IGR2096a_1 rs12521868),CARD15(R702W rs2066845 and L1007fs rs2066847),ATG16L1(rs2241880)and IL23R (rs1004819,rs2201841)genes were genotyped by PCR-RFLP,the G908R(rs2066844)in CARD15 was determined by direct sequencing. RESULTS:The association of ATG16L1 T300A with CD was confirmed[P=0.004,odds ratio(OR)=1.69, 95%CI:1.19-2.41],and both IL23R variants were found to represent significant risk for the disease(P= 0.008,OR=2.05,95%CI:1.20-3.50 for rs1004819 AA;P<0.001,OR=2.97,95%CI:1.65-5.33 for rs2201841 CC).Logistic regression analysis of pairwise interaction of the inflammatory bowel disease (IBD)loci indicated that IL23R,ATG16L1,CARD15 and IBD5(IGR2198a_1)contribute independently to disease risk.We also analysed the specific combina- tions by pair of individual ATG16L1,IL23R rs1004819, rs2201841,IGR2198a_1,IGR2096a_1 and CARD15 genotypes for disease risk influence.In almost all cases,the combined risk of susceptibility pairs was higher in patients carrying two different risk-associated gene variants together than individuals with just one polymorphism.The highest OR was found for IL23R rs2201841 homozygous genotype with combination of positive CARD15 status(P<0.001,OR=9.15,95% CI:2.05-40.74). CONCLUSION:The present study suggests a cumulative effect of individual IBD susceptibility loci. | Veronika Csngei Luca Járomi EnikSáfrány Csilla Sipeky Lili Magyari Bernadett Faragó Judit Bene Noémi Polgár Lilla Lakner Patrícia Sarlós Márta Varga Béla Melegh | 2010 | World Journal of Gastroenterology2010，16，2： | 2 |
