Cancer stem cells (CSCs) are considered responsible for the recurrence and chemoresistance of cancer. Dysregulated autophagy is highly prevalent in many types of cancer including pancreatic cancer and has been implicated in cytoprotection and tumor promotion. This study aimed to investigate the role of autophagy in regulating cancer stemness and(More)
Interferon-gamma (IFN-γ), a potent Th1 cytokine with multiple biological functions, can induce autophagy to enhance the clearance of the invading microorganism or cause cell death. We have reported that Concanavalin A (Con A) can cause autophagic cell death in hepatocytes and induce both T cell-dependent and -independent acute hepatitis in immunocompetent(More)
We have reported both T-cell-dependent and -independent hepatitis in immunocompetent and immunodeficiency mice, respectively, after intravenous injection of Con A in mice. The mode of hepatocyte cell death is different: autophagy for T-cell-independent hepatitis in contrast to apoptosis for T-cell-dependent one. In this study, we further demonstrate that(More)
Liver cirrhosis and hepatocellular carcinomas are two major causes of morbidity and mortality worldwide, and can synergistically interact to expedite the tumor progression. How fibrosis promotes the hepatoma growth remains completely unexplained. Using an in situ murine hepatoma model together with fibrosis induction by thioacetamide (TAA), the hepatoma(More)
Liver fibrosis is a risk factor for hepatoma. Activated hepatic stellate cells (HSCs) play a critical role in progression of hepatoma. Resected hepatoma patients with high α-SMA+HSCs infiltration had worse survival, OR: 2.2 and p=0.0434. We hypothesized that HSCs could increase the epithelial-mesenchymal transition (EMT) ability of hepatoma cells. In murine(More)
