| 1 | COOH-terminal deletion of HBx gene is a frequent event in HBV-associated hepatocellular carcinoma显示文摘AIM:To investigate the hepatitis B virus (HBV) x gene (HBx) state in the tissues of HBV-related hepatocellular carcinoma (HCC) in Chinese patients and whether there were particular HBx mutations. METHODS: HBx gene was amplified and direct sequencing was used in genomic DNA samples from 20 HCC and corresponding non-cancerous liver tissues from HBsAg-positive patients. HBV DNA integration and HBx deleted mutation were validated in 45 HCC patients at different stages by Southern blot analysis and polymerase chain reaction methods. RESULTS: The frequencies of HBx point mutations were significantly lower in HCC than their corresponding non- cancerous liver tissues (11/19 vs 18/19, P = 0.019). In contrast, deletions in HBx gene were significantly higher in HCC than their non-cancerous liver tissues (16/19 vs 4/19, P < 0.001). The deletion of HBx COOH-terminal was detected in 14 HCC tissues. A specific integration of HBx at 17p13 locus was also found in 8 of 16 HCC, and all of them also exhibited full-length HBx deletions. Integrated or integrated coexistence with replicated pattern was obtained in 45.5% (20/45) - 56.8% (25/45) tumors and 40.9% (18/45) - 52.3% (23/45) non-tumor tissues. CONCLUSION: HBx deletion, especially the COOH- terminal deletion of HBx is a frequent event in HBV-associated HCC tissues in China. HBV integration had also taken place in partial HCC tissues. This supporting the hypothesis that deletion and probably integrated forms of the HBx gene may be implicated in liver carcinogenesis. | Xiao-Hong Liu Jing Lin Shu-Hui Zhang Shun-Min Zhang Mark A Feitelson Heng-Jun Gao Ming-Hua Zhu | 2008 | World Journal of Gastroenterology2008，14，9： | 24 |
| 2 | Oxidative stress and antioxidants in hepatic pathogenesis显示文摘Long term hepatitis B virus (HBV) infection is a major risk factor in pathogenesis of chronic liver diseases,including hepatocellular carcinoma (HCC). The HBV encod-ed proteins,hepatitis B virus X protein and preS,appear to contribute importantly to the pathogenesis of HCC. Both are associated with oxidative stress,which can damage cellular molecules like lipids,proteins,and DNA during chronic infection. Chronic alcohol use is another important factor that contributes to oxidative stress in the liver. Previous studies reported that treatment with antioxidants,such as curcumin,silymarin,green tea,and vitamins C and E,can protect DNA from damage and regulate liver pathogenesis-related cascades by reducing reactive oxygen species. This review summarizes some of the relationships between oxidative stress and liver pathogenesis,focusing upon HBV and alcohol,and suggests antioxidant therapeutic approaches. | Hye-Lin Ha Hye-Jun Shin Mark A Feitelson Dae-Yeul Yu | 2010 | World Journal of Gastroenterology2010，16，48： | 18 |
| 3 | Differentially expressed genes in hepatocellular carcinoma induced by woodchuck hepatitis B virus in mice显示文摘INTRODUCTIONHepatocellular carcinoma(HCC)is one of the major causes of death in the word.The mechanism of carcinogenesis is unknown,although it is widely accepted that HBV and HCV are clsely related to liver cancer[1-5[1-5].Previously,a variety of studies have described the differences in gene expression which distinguished tumor from nontumor[6-11].Cloning of the genes,especially the genes associated with HBV and HCV,is still very important to account for the development of liver cancer. | Mark Feitelson | 2001 | World Journal of Gastroenterology2001，7，4： | 11 |
