RNA-Seq experiment of primary hepatic stellate cells (HSCs) and LX-2 cell line treated with TGFb

Liver fibrosis stands as the most prominent predictor of overall mortality in non-alcoholic steatohepatitis (NASH). The fibrotic liver features excessive deposition of extracellular matrix (ECM), primarily produced from "activated" hepatic stellate cells (HSCs). Whereas targeting HSC in fibrosis therapeutics shows promise, the current identification of human genetic regulators driving HSC activation is far from complete. This knowledge gap largely emanates from the limited understanding of the vast array of long non-coding RNAs (lncRNAs). Analyzing differentially regulated human lncRNAs under various regulatory patterns often provides the most practical means to inform their function. To get human lncRNA regulators in driving HSC activation, we cultured both primary human stellate cells and LX-2 cells. Then, we treated them with TGFb to mimic the activation process in vitro. Differentially expressed lncRNAs can be obtained from RNAseq results, which may guide the characterization of lncRNAs relevant to HSC activation.
