clinical significance of precore and core promoter mutations in genotype d hepatitis b-related chronic liver disease
background: hepatitis b virus (hbv) infection is the most common cause of end-stage liver disease in iran. more than 70% of cases are negative for the hepatitis b e antigen (hbeag) and have a long-term response to antiviral therapy, as well as a high relapse rate after discontinuing lamivudine or interferon. these features could be due, in part, to genetic variation of the hbv genome. materials...
متن کاملClinical significance of precore and core promoter mutations in genotype D hepatitis B-related chronic liver disease.
SUMMARY The impact of mutations in the precore and basal core promoter (BCP) regions of the hepatitis B virus on the course of chronic liver disease is not well established. We sought to examine the relationship of these characteristics to the clinical expression of liver disease in patients infected with genotype D chronic hepatitis B (CHB). BCP and precore mutations in 110 patients with genot...
متن کاملCore promoter and precore mutants of hepatitis B virus: prevalence and clinical relevance in chronic hepatitis patients.
The present study was conducted to determine prevalence and exact type, as well as nucleotide position of the precore/core mutations of hepatitis B virus found in Thai patients diagnosed with chronic hepatitis and/or cirrhosis in relation to the clinical parameters established with the respective patients. To that end, 24 HBeAg-positive and 56 HBeAg-negative individuals were selected at random ...
متن کاملEvaluation of miR-101 Level in Patients with Chronic Hepatitis B Virus Infection and Liver Cirrhosis
ABSTRACT Background and Objective: MiRNAs are small RNAs that are expressed in most eukaryotes, and can regulate gene expression by attaching to the 3’ end of target mRNA. MicroRNA-101 (miR-101) post-transcriptional regulation is important for host-virus interactions. In addition, miR-101 has a tumor suppressive role in liver cancer and metastasis, an...
متن کاملMutations at Nucleotide 1762, 1764 and 1766 of Hepatitis B Virus X Gene in Patients with Chronic Hepatitis B and Hepatitis B-Related Cirrhosis
Abstract Background and objective: Hepatitis B virus (HBV) is a DNA virus with high tendency toward hepatic tissue. There are currently about 3 million HBV-infected people and 350 to 400 million chronic carriers of this virus in the world. X protein plays a role in the over-expression of oncogenes, carcinogenicity of liver cells and overlaps with the basal co...
