Identification of differentially expressed mRNAs after activation of LX-2 cells

ABSTRACT: In this study, high-throughput RNA sequencing technology combined with bioinformatics analysis was used to compare the differentially expressed mRNA of TGF-β1-treated LX-2 cells with that of the control group in hopes of gaining a deeper understanding of the biological function and signaling pathway changes in the activation process of LX-2 cells, as well as to identify potential key genes regulating HSC activation.

TGF-β1/p65/MAT2A: a novel pathway involved in the regulation of intracellular SAM and liver fibrogenesis - Part1

Project description:Hepatic stellate cell (HSC) activation induced by transforming growth factor β (TGF-β1) plays a pivotal role in the fibrogenesis. The complex downstream mediators of TGF-β1 are largely unknown. Here, proteomics analysis and biological validation demonstrated that methionine adenosyltransferase 2A (MAT2A) was significantly upregulated in a CCl4-induced fibrosis mice model and a small molecule NPLC0393, known to block TGF-β1/Smad3 signaling, inhibited its upregulation. In HSC cells, TGF-β1 induced elevation of MAT2A and MAT2β expression as well as reduction of S-adenosylmethionine (SAM) content, which further promoted HSC activation. Functionally, in vivo and in vitro knockdown of MAT2A alleviated CCl4- and TGF-β1-induced HSC activation, whereas in vivo overexpression of MAT2A facilitated hepatic fibrosis and abolished therapeutic effect of NPLC0393. TGF-β1 induced p65 phosphorylation and NF-κB activation, thereby promoted the transcription of MAT2A and its protein expression. In addition, overexpression of p65 abrogated NPLC0393 mediated inhibition of HSC activation. This study identified a novel pathway TGF-β1/p65/MAT2A that was involved in the regulation of intracellular SAM contents and liver fibrogenesis, suggesting that this pathway is a potential therapeutic target for hepatic fibrosis.

Expression data from the hepatic stellate cell line LX-2 after treatment with DMOG and from the liver sinusoidal endothelial cell line TRP3 after incubation with conditioned medium of DMOG-treated LX-2

Project description:Expression data from the hepatic stellate cell line LX-2 after treatment with the prolylhydroxylase inhibitor dimethyloxalylglycine (DMOG) and from the liver sinusoidal endothelial cell line TRP3 after incubation with conditioned medium of DMOG-treated LX-2 Prolyl-hydroxylase inhibitors such as dimethyloxalylglycine (DMOG) stabilize HIF-1α, thereby chemically inducing hypoxia, which also accelerates liver volume increase when given with portal rerouting. We used microarrays to clarify the cellular crosstalk of the different cell types in accelerated liver regeneration by examining the role of hepatic stellate cells (HSC) and liver sinusoidal endothelial cells (LSEC).

Investigation of hepatic stellate cell proteomics during activa-tion with fetal bovine serum

Project description:Hepatic stellate cells (HSCs) are the major driving factor in liver fibrosis. Upon liver inflammation caused by alcohol abuse and/or a fatty liver, HSCs transform from a quiescent- into a proliferating, fibrotic phenotype. We study this transformation termed “activation”, using state of the art TIMS-TOF mass spectrometry proteomics, as well as phenotype analysis of the immortalized LX-2 HSC cell line. In our work we employ a simple, yet reliable model of HSC activation via an in-crease in growth media serum concentration (serum activation). Protein network analysis of ac-tivated LX 2 cells reveals an increase in the production of ribosomal proteins and proteins related to migration. Interestingly, we could also observe a decrease in the expression of lipogenic pro-teins and a loss of cytosolic lipid droplets during activation. Especially the downregulation of proteins associated with cholesterol biosynthesis might be a promising target for further study. This work provides an update on HSC activation characteristics using contemporary proteomic and bioinformatic analysis and presents an accessible model for HSC activation.
