Project description:Hepatic stellate cells(HSCs) are the main effector cells of liver fibrosis. In order to study the effect of mesenchymal stem cells(MSCs) on microRNAs expression of HSCs, we co-cultured HSCs LX-2 activated by TGFβ1 with human umbilical cord MSCs(hUC-MSCs) for 48 hours, and compared the differentially expressed miRNA with LX-2 cultured alone by high-throughput sequencing. The results showed that two mature microRNAs expressed increased, and nine expressed decreased.
Project description:To investigate the role of AEBP1 involved in hepatic stellate cells (HSCs), we inhibited AEBP1 expression by specific siRNA in human HSC line LX-2 cells. Total RNA was loaded for bulk RNA sequencing.
Project description:We found that the number of tumor-infiltrating myofibroblasts was positively correlated to tumor acidification status in hepatocellular carcinoma (HCC). Hepatic stellate cells (HSCs), the predominant precursors of liver myofibroblasts, were activated and transdifferentiated into myofibroblasts under acidic culture condition. To identify the molecular phenotype of LX-2 cells in acidic culture conditions, we further conducted a gene expression profile analysis. LX-2 cells cultured in pH 7.2 or pH 6.2 medium separately for six days was used in gene expression microarray analysis.
Project description:Liver fibrosis is characterized by deposition of excessive extracellular matrix (ECM). The major source of ECM is activated hepatic stellate cells (HSCs).NAT10 is the only known acetyltransferase catalyzing ac4C RNA modification. The purpose of this transcriptome is to explore the role of NAT10 acting as ac4C acetyltransferase during HSC activation.
