Figure 1 Common and specific telomere abnormalities between HBV-, HCV-, and alcohol-associated cirrhosis and hepatocellular carcinoma. A. Distribution of hTERT and hTER expression,

telomerase activity and TRF length among the main causes of hepatocellular carcinoma. B. Alteration in shelterin and non-shelterin gene expression at the two main steps www.selleckchem.com/products/LBH-589.html of liver carcinogenesis in vivo. Significantly overexpressed genes (p < 0.05, Mann Whitney test) are represented in black whereas significantly underexpressed genes are represented in gray. Figure 2 Immunohistochemistry and Western-blot analysis. (A) Ki67, (B) hTERT, (C ,D) shelterin and non-shelterin and (D) telomere factors in the main causes

of cirrhosis and hepatocellular carcinoma. Telomere deregulation at the early stage of HBV-associated hepatocarcinogenesis Expression of the proliferative marker Ki67 was not significantly different between the 8 HBV positive cirrhotic samples and the 12 non-cirrhotic liver samples deriving from patients with HCC. As illustrated in Figure 1A, the level of hTERT expression was significantly higher in the 8 HBV positive Fossariinae cirrhotic samples than in the 12 non-cirrhotic liver samples (p = 0.040, Mann–Whitney test).

In contrast, there was no significant difference in the level of TA between the cirrhotic and non-cirrhotic sample categories. HBV-associated cirrhosis expressed significantly lower hTR levels when compared to histologically non-cirrhotic liver tissue: 0.0053 versus 0.3574 arbitrary units (p < 10-4, Mann–Whitney test) (Figure 1A). The TRF length was longer in HBV positive cirrhotic samples than in non-cirrhotic samples (6.60 kbp versus 5.69 kbp) but the difference was not statistically significant. Comparative Western-blot analysis of hTERT expression in HBV positive cirrhotic samples versus non-cirrhotic liver samples confirmed the qRTPCR results for hTERT expression (Figure 2B). Table 2 and Figure 1B show that all shelterin and non-shelterin telomere factors except HMRE11A and RAD50 were significantly underexpressed in HBV positive peritumoral cirrhotic samples.
