(Submitter supplied) Hepatic stellate cells (HSCs) are the primary cell type responsible for liver fibrosis, the final common pathway leading to cirrhosis and liver failure for nearly every cause of chronic liver disease. Activation of HSCs in response to injury represents the key step in hepatic fibrogenesis, and is characterized by a phenotypic change from a non-fibrogenic, quiescent HSC to a fibrogenic HSC myofibroblast that secretes extracellular matrix proteins responsible for the fibrotic scar. more...

(Submitter supplied) We report the RNA sequencing results of human primary hepatic stellate cells (HSCs) treated with DMSO or 1 µM nanchangmycin (NCMC) for 48 hours. We find that multiple HSC activity and liver fibrosis related gene signatures, including ECM-related gene signatures, are negatively enriched in nanchangmycin treated HSCs.

(Submitter supplied) Activation of quiescent hepatic stellate cells (HSCs) into proliferative myofibroblasts drives extracellular cellular matrix (ECM) accumulation and liver fibrosis; nevertheless, transcriptional network that promotes such the process remains elusive. ZNF469, a putative C2H2 zinc finger protein, is found to be upregulated upon HSC activation; however, the molecular function of ZNF469 is completely unknown. more...

(Submitter supplied) Hepatic stellate cells are the primary cell type responsible for development of fibrosis in chronic liver disease. We used directional RNA sequencing (RNA-seq) and chromatin immunoprecipitation and sequencing (ChIP-seq) to identify the lncRNAs expressed in human HSCs. We also identified the lncRNAs that change in expression with differentiation of nonfibrotic quiescent HSCs into fibrotic HSC myofibroblasts and those that are regulated by TGF-beta signaling. more...

(Submitter supplied) Background/Aims: Sept4, a subunit of the septin cytoskeleton specifically expressed in quiescent hepatic stellate cells (HSCs), is downregulated through transdifferentiation to fibrogenic and contractile myofibroblastic cells. Since Sept4−/− mice are prone to liver fibrosis, we examined the unknown molecular network underlying liver fibrosis by probing the association between loss of Sept4 and accelerated transdifferentiation of HSCs. more...

(Submitter supplied) BACKGROUND & AIMS: Nonalcoholic steatohepatitis (NASH) is a chronic liver disease characterized by hepatic lipid accumulation, inflammation, and progressive fibrosis. Acetyl-CoA carboxylase (ACC) catalyzes the rate-limiting step of de novo lipogenesis and regulates fatty-acid beta-oxidation in hepatocytes. ACC inhibition reduces hepatic fat content and markers of liver injury in NASH patients; however, the effect of ACC inhibition on liver fibrosis has not been reported. more...

(Submitter supplied) Hepatic stellate cells (HSC) are the main stromal cell component of the liver. In healthy liver, quiescent HSC participate in the homeostasis of extracellular matrix (ECM) and store vitamin A. Liver injury causes HSC activation, where they participate in the wound-healing response, by producing ECM components as well as cytokines involved in liver regeneration and inflammation. Moreover, HSC are the main cell type responsible for fibrosis progression. more...

(Submitter supplied) Hepatic fibrosis is the common end stage to a variety of chronic liver injuries and is characterized by an excessive deposition of extracellular matrix (ECM), which disrupts the liver architecture and impairs liver function. The fibrous lesions are produced by myofibroblasts, which differentiate from hepatic stellate cells (HSC). The myofibroblasts transcriptional networks remain poorly characterized. more...

(Submitter supplied) FOXF1, a member of the forkhead box family of transcription factors, has been previously shown to be critical for lung development, homeostasis, and injury responses. However, the role of FOXF1 in lung regeneration is unknown. Herein, we performed partial pneumonectomy, a model of lung regeneration, in mice lacking one Foxf1 allele in endothelial cells (PDGFb-iCre/Foxf1fl/+ mice). Endothelial cell proliferation was significantly reduced in regenerating lungs from mice deficient for endothelial Foxf1. more...

(Submitter supplied) BACKGROUND & AIMS: Cirrhosis affects 1% to 2% of the world population and is the major risk factor for hepatocellular carcinoma (HCC). Hepatitis C cirrhosis-related HCC is the most rapidly increasing cause of cancer death in the United States. Noninvasive methods have been developed to identify patients with asymptomatic early-stage cirrhosis, increasing the burden of HCC surveillance, but biomarkers are needed to identify patients with cirrhosis who are most in need of surveillance. more...

(Submitter supplied) Hepatic stellate cells (HSCs) are the major driver of fibrosis by expressing extracellular matrices (ECM). HSCs, in the normal liver, are quiescent and activated by liver injury to become myofibroblasts that proliferate and produce ECM. It has been shown that activated HSCs can be deactivated by removal of liver insults. In order to evaluate the changes of gene expression profiles, we induced quiescent HSCs (qHSCs), activated HSCs (aHSCs) and deactivated HSCs (daHSCs) from human induced pluripotent stem cells and performed RNA-sequence analysis.
