Hepatocellular carcinoma and hepatitis B e antigen.
Hepatitis B e antigen serum persistence in an individual chronically infected with the Hepatitis B virus may be associated with a greatly increased risk of developing cirrhosis and hepatocellular carcinoma. This article presents an overview of the Hepatitis B e antigen and discusses the findings of a recent study evaluating its associated risk of hepatocellular carcinoma. A gross photographic i...
متن کاملImmunohistochemical detection of aflatoxin B1-DNA adducts and hepatitis B virus antigens in hepatocellular carcinoma and nontumorous liver tissue.
Monoclonal antibodies recognizing the stable imidazole ring-opened form of the major N7-guanine aflatoxin B1-DNA adduct have been used in competitive enzyme-linked immunosorbent assays (ELISA) and indirect immunofluorescence assays to quantitate adduct levels in liver tissue. Methods were developed in AFB1-treated animals, then applied to paired tumor and nontumor liver tissues of hepatocellula...
متن کاملExpression of Hepatitis B Virus Core Antigen in Native and Fusion Forms in E. coli
DNA coding for the core antigen from hepatitis B Virus (HBcAg) was amplified, cloned and propagated in E. coli. The core protein was expressed in E. coli and the product was readily detected by Western blot. This protein can be used as a diagnostic material in serum screening tests. To increase the level of expression of this antigen in bacteria, two plasmids were constructed in which the gene ...
متن کاملhepatitis b virus core promoter mutations in patients with chronic hepatitis b and hepatocellular carcinoma in bucharest, romania
conclusions genotype d was the main genotype detected in romanian patients with chronic hbv infection. genotype d presented both bcp and pc mutations more frequently. results we detected two hbv genotypes; a (8.1%) and d (60.5%), and a mixture of genotypes a and d (31.4%) (p < 0.001). basal core promoter (bcp) a1762t/g1764a and precore (pc) g1896a mutations were detected in these romanian patie...
متن کاملHepatitis B and hepatocellular carcinoma.
Chronic infection with the hepatitis B virus has been linked epidemiologically to the development of hepatocellular carcinoma for more than 30 years. Although the mechanisms by which chronic hepatitis B viral infection results in hepatocellular carcinoma are unclear, there is good evidence that the virus itself exerts a direct hepatocarcinogenic effect, and this has implications for prevention....
