Therefore, down-regulation of mir302b and mir20a during early liver development may relieve the suppression of TGFβ signaling to promote hepatoblast proliferation. www.selleckchem.com/products/iwr-1-endo.html We thank Wenbo Xu and David Ho for technical assistance, and Dr. Nagarajan Kannan, Dr. Jeremy

“BACKGROUND AND AIM: Hepatocellular carcinoma (HCC) is an important complication of cirrhosis with an increasing incidence in the U.S. most likely due to hepatitis C virus (HCV). The only potentially curative treatment option for HCC is liver transplantation. METHODS: All adults (18+) who underwent liver transplantation for HCC were

included from the Scientific Registry of Transplant Recipients (1992-2013). Etiology of liver disease (LD) was grouped into HCV (anti-HCV-posi-tive), hepatitis click here B (HBV, HBsAg-positive), and other LD (negative viral hepatitis serology). RESULTS: Total 8,625 liver transplant recipients with HCC were included; 5,471 had HCV, 604 HBV, and 2,387 had other causes of LD. In comparison to hepatitis C, patients with hepatitis B were predominantly Asian (60.3%) and male (83.0%), had lower rates of pre-transplant obesity (HBV 11.4% vs. 30.1% in hepatitis C, 37.9% in other LD, p<0.0001), diabetes (HBV 14.2% vs. HCV 17.5% and other LD 30.5%, respectively, p<0.0001). Important comorbid-ities MCE were equally prevalent regardless of etiology (coronary artery disease, stroke, peripheral vascular disease, pulmonary embolism, cancer) (all p>0.05). In follow-up (43±38 months), 7.9% of HCC patients had graft failure and 27.8% died. HCV patients with HCC had highest average rate of graft failure: HBV 5.5% vs. HCV 8.9% vs. 6.4% in other LD (p<0.0001). After 1 year of follow-up, graft failure rates were similar in all HCC patients (4.8%-5.4%,

p=0.55). Despite this, starting year 3 post-transplant, the cumulative risk of graft failure in HCV patients became significantly higher (HCV 11.4% vs. HBV 6.6% vs. other LD 8.0%, p=0.0003) and remained high by follow-up year 5 (HCV 14.5% vs. HBV 8.1% vs. other LD 9.9%, 0.0007). The lowest post-transplant mortality rate was observed in HBV patients (HBV: 19.9% vs. HCV 29.1% and other LD 26.9%, p<0.0001). In fact, this difference was borderline significant starting as early as 1 year post-transplant (HBV 8.5% vs. HCV 12.0%, other LD 11.4%, p=0.0596), became highly significant by year 3 (HBV 15.5% vs. HCV 27.0% and other LD 22.7%, p<0.0001). In multivariate analysis of HCC patients, having hepatitis C was independently associated with an increased risk of both graft failure (aHR (95% CI) = 1.73 (1.35-2.21), p<0.0001) and mortality (1.34 (1.20-1.49), p<0.0001).
