Project description:Gene expression profiling of immortalized human mesenchymal stem cells with hTERT/E6/E7 transfected MSCs. hTERT may change gene expression in MSCs. Goal was to determine the gene expressions of immortalized MSCs.
Project description:Transcriptional profiling of human mesenchymal stem cells comparing normoxic MSCs cells with hypoxic MSCs cells. Hypoxia may inhibit senescence of MSCs during expansion. Goal was to determine the effects of hypoxia on global MSCs gene expression.
Project description:Virus species- and tissue-tropism is governed by host dependency and restriction factors. Hepatitis C virus (HCV) exhibits a narrow species-tropism and murine hepatocytes are refractory to infection. Using murine liver cDNA library screening we identified Cd302, a lectin, and Cr1l, a complement receptor, as pan-genotypic restrictors of HCV infection. Cd302/Cr1l interact to impede virion uptake and co-operatively induce a non-canonical transcriptional program, inhibiting HCV and hepatitis B virus (HBV) infection in vitro. CAS9 disruption of murine hepatocyte Cd302 expression increased HCV permissiveness in-vivo and ex-vivo, and modulated the intrinsic hepatocyte transcriptome dysregulating metabolic process and host defense genes. In contrast, co-operative CD302/CR1L expression was absent and HCV restriction reduced in human hepatocytes. The Cd302/Cr1l axis therefore contributes to limiting hepatotropic virus cross-species transmission to mice, opening new avenues for step-wise development of mouse models for these important human pathogens, which cause substantial disease burden globally.
