Cellular protein discovered that interferes with hepatitis C virus replication Biomedical researchers have identified a cellular protein that interferes with hepatitis C virus replication, a discovering that ultimately can help scientists develop brand-new drugs to fight the virus. The anti-hepatitis C activity of the proteins, known as ,p21-activated kinase 1, , was uncovered by researchers at the University of Texas Medical Branch at Galveston , who describe their findings within an article in today’s issue of the Journal of Biological Chemistry. In addition to presenting the researchers, discovery that PAK1 controls the rate at which hepatitis C virus replicates, the paper describes the biochemical pathways that result in PAK1 activation and the precise mechanisms where PAK1 interferes with the power of hepatitis C to hijack liver cells and make more copies of itself sildenafil citrate .
