Research Abstract

We intensively examined on hepatic stellate cells (HSC) for the treatment strategy of liver fibrosis. The present study focused on epigenetic alterations within the process of HSCs transformation. Using Gia-base sequencing method, global alterations of DNA methylation were examined in HSC under the condition of HDAC inhibitor (TSA) and interferon (IFN)-γ. Of them, genes relating pluripotency of stem cells were altered, and the nucleus accumbens associated-1 (NACC1) might be an important factor along with cMYC and NANOG. These transition of HSC might be induced though epigenetic alterations.
