The non-structural protein 5A (NS5A) of some hepatitis C virus (HCV) isolates has been implicated in the inhibition of the antiviral activity of interferon (IFN). In the present study, the possible inhibitory effects of NS5A from two isolates of HCV subtype 1b, HCV-1bJk and M094AJk, and their chimeric form on the antiviral activity of IFN were examined.(More)
The sensing of pathogen infection and subsequent triggering of innate immunity are key to controlling zoonotic infections. Myxoma virus (MV) is a cytoplasmic DNA poxvirus that in nature infects only rabbits. Our previous studies have shown that MV infection of primary mouse cells is restricted by virus-induced type I interferon (IFN). However, little is(More)
The authors have recently demonstrated that wild-type myxoma virus (MV) tagged with gfp (vMyxgfp) can generate a tumor-specific infection that productively infects and clears human tumor-derived xenografts when injected intratumorally into human gliomas transplanted into immunodeficient mice (Lun et al, 2005). To expand the understanding of MV tropism in(More)
Micro RNA (miR)-486-5p is often aberrantly expressed in human cancers. The aim of this study was to identify the prognostic value of miR-486-5p expression in digestive system cancers. Tissue microarrays were constructed with 680 samples including 185 esophageal squamous cell carcinomas (ESCCs), 90 gastric adenocarcinomas (GCs), and 60 digestive system(More)
Fibroblast growth factor (FGF) 9 is a member of the FGF family, which promotes carcinogenesis in some solid tumours. However, its biological and prognostic significance in gastric cancer (GC) is unclear. We examined FGF9 expression in 180 GC and corresponding non-tumorous gastric tissue samples by immunohistochemistry and evaluated its role in predicting(More)
The exact effect of hypoxia on cancer development is controversial. The present study investigates the ability of osteosarcoma to form tumors in the hypoxic microenviron-ment induced by CoCl 2. MG63 human osteosarcoma cells were cultured with different concentrations (0, 150 and 300 µM) of CoCl 2 for 24 h to simulate hypoxia in vitro. The expression of(More)
