The effects of poliovirus 3A protein expression and poliovirus infection on the presentation of hepatitis C virus antigens in cultured chimpanzee cells were examined. Expression of poliovirus 3A protein inhibits protein secretion when expressed in isolation and was sufficient to protect chimpanzee cells from lysis by hepatitis C virus-specific cytotoxic T(More)
Increased microRNA-10b (miR-10b) expression in the cancer cells in pancreatic ductal adenocarcinoma (PDAC) is a marker of disease aggressiveness. In the present study, we determined that plasma miR-10b levels are significantly increased in PDAC patients by comparison with normal controls. By gene profiling, we identified potential targets downregulated by(More)
Endoplasmic reticulum (ER)-to-Golgi traffic in yeast proceeds by the maturation of membrane compartments from post-ER vesicles to intermediate small vesicle tubular clusters (VTCs) to Golgi nodular membrane networks (Morin-Ganet et al., Traffic 2000; 1: 56-68). The balance between ER and Golgi compartments is maintained by COPII- and COPI-mediated(More)
The rate of protein secretion in host cells is inhibited during infection with several different picornaviruses, with consequences likely to have significant effects on viral growth, spread, and pathogenesis. This Sin(+) (secretion inhibition) phenotype has been documented for poliovirus, foot-and-mouth disease virus, and coxsackievirus B3 and can lead to(More)
