background: hepatitis c virus (hcv) infection is one of the most prevalent infectious diseases responsible for high morbidity and mortality worldwide. therefore, designing new and effective therapeutics is of great importance. the aim of the current study was to construct a dna vaccine containing structural proteins of hcv and evaluation of its expression in a eukaryotic system. methods: struct...

Background and Aims: The hepatitis C virus (HCV) F protein is a recently described, frameshift product of HCV core encoding sequence. Its function and antigenic properties are unknown. In order to assess the presence of antibodies specific for F protein we characterized specific anti-F antibodies in patients with chronic HCV infection. Methods: The F protein was cloned from the HCV genome....

hepatitis c virus (hcv) is an important agent causing chronic liver infection, which often leads to liver cirrhosis and lethal hepatocellular carcinoma (hcc). at present, there is no effective hcv vaccine for prevention of hepatic disease and the standard treatment is neither economical nor fully effective in all the patients. however, vaccination based on structural and nonstructural proteins ...

BACKGROUND AND OBJECTIVES Hepatitis C virus (HCV) chronically infects around 200 million people worldwide and frequently causes liver cirrhosis and hepatocellular carcinoma. Rapid detection of this virus results in decreasing the distance between infection and initiation the anti-viral treatment, and may prevent most of the undesirable consequences. The new detected HCV protein "Core+1" made fr...

Allergic reactions to peanuts and tree nuts are major causes of anaphylaxis in the United States. We compare different properties of natural and recombinant versions of Ara h 1, a major peanut allergen, through structural, immunologic, and bioinformatics analyses. Small angle x-ray scattering studies show that natural Ara h 1 forms higher molecular weight aggregates in solution. In contrast, th...

The basal transcription factor SNAPc binds to the PSE, a core element in the RNA polymerase II and III human snRNA promoters. SNAPc contains at least four subunits, but it has not been possible to assemble a fully defined recombinant SNAPc. Here we reconstitute SNAPc from five recombinant subunits, SNAP43, SNAP45, SNAP50, SNAP190, and a newly identified subunit, SNAP19. This recombinant complex...
