In addition, XIAP and CAS mRNA expression levels were correlated in HCC patient samples (r = 0.463; P < 0.01), supporting the in vivo relevance of our findings. Furthermore, quantitative mass spectrometry analyses of murine HCC samples (p53−/− versus p53+/+) indicated higher protein expression of CAS and imp-α1 in p53−/− tumors. Consistent with a role of p53 in regulating the CAS/imp-α1 transport cycle, we observed that both transport factors were repressed upon p53 induction in a p21-dependent manner. Conclusion: The CAS/imp-α1 transport cycle is linked

to XIAP and is required to maintain tumor cell survival in HCC. Moreover, CAS and imp-α1 are targets SB525334 in vivo of p53-mediated repression, which represents a novel aspect of p53′s ability to control tumor cell growth in hepatocarcinogenesis. (Hepatology 2014;60:884–895) “

“Purpose: Since hepatocellular carcinoma (HCC) sometimes develops in patients with chronic hepatitis C even after they have achieved sustained virologic response (SVR), i.e., the eradication of hepatitis C virus (HCV), after antiviral

therapy, surveillance for HCC is necessary after SVR. We investigated the incidence and risk factors for HCC in HCV-infected patients who medchemexpress achieved SVR. Methods: The incidence of HCC and risk factors for its development were prospectively evaluated in 522 patients (293 males and 229 females) who achieved SVR with interferon-based antiviral therapy for HCV. All patients continued regular outpatient visits to our institution every 6 months for HCC surveillance after SVR. The FIB-4 index was calculated at the achievement of SVR. Results: Patients continued regular visits for surveillance for 0.5 to 22.9 years (median, 9.1 years) after SVR. HCC developed in 16 patients. The incidence of HCC was 1.2% at 5 years and 4.3% at 1 0 years, which was significantly lower than that of 51 6 HCV-infected patients with persistently normal alanine aminotransferase levels observed at our institution (p<0.0001). By univariate analysis, age >60 years (odds ratio, 1.77; p=0.0238), male sex (1.74; p=0.0565), habitual alcohol intake (1.89; p=0.0261), diabetes mellitus (1.79; p=0.0696), pretreatment fibrosis grade of F2 or higher based on liver biopsy (2.17; p=0.0025), FIB-4 index >2 (2.43; p=0.0047) and FIB-4 index >4 (4.15; p=0.0002) at the achievement of SVR were associated with a higher incidence of HCC.
