HBV-X protein is associated with the pathogenesis of HBV related diseases, especially hepatocellular carci-noma in chronic patients. Genetic variability of the X gene includes genotypic specific variations and mutations emerging during chronic infection. The double mutation of nucleotide A1762T/G1764A in basal core promoter

Mar 12, 2020 HCC, the genotypic and phenotypic features associated with these risk factors in HCC are greatly diverse. In addition, mortalities from HCC are mainly due to hepatitis B and C virus infections, which explained 78.5% of HCC-induced mortality in 2013 [6]. Although hepatocellular carcinogenesis in patients with LC largely appears to be a continuous,

around 55-85% in later period of their lives progress to chronic HCV infection, which further leads to liver fibrosis, cirrhosis and eventually hepatocellular carcinoma (HCC) in 15-30% of those having chronic hepatitis C [4]. In suspected patients diagnosis is confirmed by serology and/or molecular methods. However,

chronic HCV infection develops in the remaining 75% of those infected and can lead to the development of liver cirrhosis and hepatocellular carcinoma (2 4). HCV contains a 9.6-kb positive-strand RNA genome that codes for three structural and seven nonstructural proteins. The nonstructural protein 5B (NS5B) is the viral RNA-dependent

Hepatitis C Virus: Evading the Intracellular Innate Immunity

Mar 13, 2020 Abstract: Hepatitis C virus (HCV) infections constitute a major public health problem and are the main cause of chronic hepatitis and liver disease worldwide. The existing drugs, while e ective, are expensive and associated with undesirable secondary e ects. There is, hence, an urgent need to

nfections with hepatitis C virus (HCV) are a major cause of chronic liver diseases, such as cirrhosis and hepatocellular carcinoma.1 Clinical manage-ment of HCV and the effectiveness of currently used interferon-a (IFN)/ribavirin (RBV) therapy of infected individuals is greatly influenced by genetic heterogene-ity of the virus.

Patients with chronic hepatitis B usually have no initial symptoms of infection, but over time the major disease sequelae, cirrhosis and hepatocellular carcinoma, can develop. It is estimated that some 350 million people worldwide are currently chronically infected with HBV, but many more will have been infected and recovered.

Such treatments aim at interrupting the progression and clinical outcomes of the disease (cirrhosis, hepatocellular carcinoma) by stimulating the anti-HBV-specific host immune response or by markedly decreasing viral replication.
