Alteration in hepatitis B virus (HBV) secretion efficiency may have pathological consequences. Naturally occurring mutations that regulate virion secretion have not been defined. We recently identified HBV genomes displaying high (4B), substantially reduced (3.4), or negative (4C) virion secretion. In the present study, the underlying mutations were mapped. A T552C point mutation in the 4B geno...
conclusions there is an as yet unexplained association between hcv and host parameters with unknown mechanisms in patients with chronic hcv infection. the assessments of core aa 70 substitution and polymorphisms near the ifnl3 gene could offer promising steps to improve the management of patients with hcv. background molecular studies have demonstrated that the hepatitis c virus (hcv) genotype ...
The present study aimed to evaluate the silencing effect of artificial microRNAs (amiRNAs) against the hepatitis C virus (HCV) 1b (HCV1b) genotype core (C) and non-structural protein 4B (NS4B) genes. pDsRed-monomer-Core and pDsRed-monomer-NS4B plasmids, containing the target genes were constructed. A total of eight artificial micro RNA (amiRNA)-expressing plasmids, namely, pmiRE-C-mi1 to -mi4 a...
background: hepatitis c virus (hcv) is a main public health problem causing chronic liver infection and subsequently liver cirrhosis and lethal hepatocellular carcinoma (hcc). vaccination based on hcv capsid proteins has attracted a special interest for prevention of viral infections. the core protein is a basic and evolutionary most conserved protein, which regulates the cellular processes rel...
Introduction: Hepatitis C virus (HCV) infection is a major public health problem which influences about 170 million people worldwide. Different types of vaccines have been designed using HCV structural proteins to control the viral infection. The core nucleocapsid protein is one of the most conserved proteins and a desirable target for HCV vaccines, especially the protein-based vaccines. In cur...
Inflammatory bowel disease (IBD) is characterized by an impaired intestinal barrier function. We aimed to investigate the role of reticulon-4B (RTN-4B/NOGO-B), a structural protein of the endoplasmic reticulum, in intestinal barrier function and IBD. We used immunohistochemistry, confocal microscopy, real-time PCR, and Western blotting to study tissue distribution and expression levels of RTN-4...
Background: Hepatitis C virus (HCV) is a main public health problem causing chronic liver infection and subsequently liver cirrhosis and lethal hepatocellular carcinoma (HCC). Vaccination based on HCV capsid proteins has attracted a special interest for prevention of viral infections. The core protein is a basic and evolutionary most conserved protein, which regulates the cellular processes rel...
The oligomeric structure of bacteriophage T7 gene 4 helicase/primase proteins was investigated using protein cross-linking and high pressure gel-filtration chromatography. Studies were carried out with both 4A' and 4B proteins. 4A' is a M64L mutant of 4A which has similar helicase and primase activities as the wild-type mixture of 4A and 4B proteins (Patel, S. S., Rosenberg, A. H., Studier, F. ...
Abstract Aiming at the fast opening and closing speed of GIS isolation/grounding switch, manual observation is more difficult, so it difficult to judge current switch status. This paper proposes an OpenCV-based image identification algorithm identify position movable contact during process isolating thereby judging state switch. system uses Raspberry Pi as main hardware core, server drives CMOS...
Four initiation factors (eIF-2, -3, -4B, and -4F), previously shown to be phosphorylated in vivo, are each phosphorylated to a significant extent in vitro (greater than 0.3 mol of phosphate/mol of factor) by at least three different protein kinases. An S6 kinase from liver, an active form of protease-activated kinase II which modifies the same sites on S6 as those phosphorylated in vivo in resp...
