Hepatitis C virus (HCV) and HCV core protein are hypothesized to induce hepatic oxidative stress and exacerbate injury caused by other toxins such as ethanol that induce the cytochrome P450 enzyme, CYP2E1. In the current study, the effects of HCV core protein [sequence genotype 1b, (nt 342-915)] on parameters indicative of oxidative stress were evaluated in HepG2 cells stably over expressing CY...

A self-modulating mechanism by the hepatitis C virus (HCV) core protein has been suggested to influence the level of HCV replication, but current data on this subject are contradictory. We examined the effect of wild-type and mutated core protein on HCV IRES- and cap-dependent translation. The wild-type core protein was shown to inhibit both IRES- and cap-dependent translation in an in vitro sy...

The detection and analysis of protein complexes is essential for understanding the functional mechanism cellular integrity. Recently, several techniques detecting analysing from Protein–Protein Interaction (PPI) dataset have been developed. Most those are inefficient in terms detecting, overlapping complexes, exclusion attachment complex core, inability to detect inherent structures underlying ...

MOTIVATION The prediction of the regions of homology models that can be 'restrained by' or 'copied from' the basis structures is a vital step in correct model generation, because these regions are the models most accurate part. However, there is no ideal method for the identification of their limits. In most algorithms their length depends on the number of family members and definitions of seco...

Background & Aims: The normal form of the prion protein is called PrPC and its infectious form is called PrPSc. This protein functions like a crystallized core for the transformation of PrPc into an abnormal PrPSc. The aim of the present study was to investigate the effect of temperature on human prion protein structure through molecular dynamic simulation. Methods: In this research, the GROMAC...

Hepatitis C virus (HCV) is a significant health problem facing the world. More than 170 million people are infected with HCV worldwide. HCV encodes a large polyprotein precursor that is processed into at least 10 distinct products including structural (core, E1 and E2) and non-structural (NS2, NS3, NS4A, NS4B, NS5A and NS5B). Besides its importance in virus replication, NS4A functions as a cofa...

Hepatitis B virus (HBV) infection, a cause of hepatocellular carcinoma (HCC), remains a serious global health concern. HCC development and human hepatocarcinogenesis are associated with hepatic inflammation caused by host interferons and cytokines. This article focused on the association between the HBV core protein, which is one of the HBV-encoding proteins, and cytokine production. The HBV co...

The complete nucleotide sequence of a mouse mastocytoma proteoglycan core protein mRNA was determined. The mRNA, estimated to contain 1.1 kb, encodes a protein with an Mr of 16715. A 21-amino acid-residue region of the protein is composed of alternating serine and glycine residues. Southern-blot analysis of mouse genomic DNA with cDNA containing sequences corresponding to the Ser-Gly repeat reg...

Recent crystallographic studies have shown that both backbone and side-chain adjustments occur when different core-packing arrangements are accommodated in proteins. Thus, modeling methods, which have typically considered only side-chain adjustments, must now also account for backbone movements to accurately predict the energies and structures of mutated or designed proteins. The 'plasticity' o...
