Hepatitis B virus suppression through pEPI vectors and expression of small non-coding RNA molecules
نویسندگان
چکیده
Aims Hepatitis B virus (HBV) infections in early childhood are associated with a high risk of chronification and the subsequent risk of cirrhosis and development of hepatocellular carcinoma (HCC) in adulthood. Immunization success rates are still suboptimal and treatment options bare considerable undesired side effects and drug resistance development. As a novel experimental therapeutic approach we investigated on the utilization of siRNAs in order to suppress HBV replication.

Analysis of Immumoreactivity of Heterologously Expressed Non-structural Protein 4B (NS4B) from Hepatitis C Virus (HCV) Genotype 1a
Background: Detection of hepatitis C virus specific antibodies is the initial step in chronic HCV diagnosis. HCV NS4B is among the most immunogenic HCV antigens and has been widely used in commercial Enzyme Immunoassays (EIA). Additionally, NS4B, a key protein in the virus replication, can be an alternative target for antiviral therapy. Objectives: Development of a new method for high-level ex...
متن کاملTransient expression of coding and non-coding regions of PVY confer resistance to virus infection
One of the most efficient mechanisms by which plants protect themselves from invading virusesis the specific RNA-dependent silencing pathway termed post-transcriptional gene silencing(PTGS). In this mechanism, resistance to a virus is engineered through the expression of asegment of the virus genomein transgenic plants. Potato VirusY (PVY) is one of the mostdamaging viruses of potato, infecting...
متن کاملEXPRESSION OF HEPATITIS B SURFACE ANTIGEN IN SACCHAROMYCES CEREVISIAE
The genome of HB V virus of serotype ayw cloned in pBR322 and expression shuttle vector p YES2 were used for construction of the HBsAg chimeric genes and their expression in Saccharomyces cerevisiae. Two recombinant plasmids were constructed. One of them contained the coding sequences for the major polypeptide of surface antigen. Another construct carried the major polypeptide with the pre-S2 a...
متن کاملDownregulated long non-coding RNA DREH promotes cell proliferation in hepatitis B virus-associated hepatocellular carcinoma
The hepatitis B virus X (HBx) protein has been characterized as an oncogene involved in epigenetic modifications during hepatocarcinogenesis; however, the underlying mechanisms are not entirely clear. Long non-coding RNAs (lncRNAs), a type of epigenetic regulator molecules, have also been demonstrated to serve crucial roles in carcinogenesis, including hepatocellular carcinoma (HCC). In the pre...
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...
