Project description:Endoglin is a transmembrane receptor able to bind several members of the transforming growth factor-beta superfamliy. We used a siRNA-mediated knock down approach to analyse the function of Endoglin in hepatic stellate cells (HSC). We found that the targeted disruption is associated with significant changes in gene expression resulting in cellular changes that prolongated cellular activation, morphological maturation, transdifferentiation, expression of basement and fibrillar extracellular matrix proteins. In addition, the lack of Endoglin resulted in rearrangements of cytoskeletal organization. Keywords: gene function analysis, siRNA, gene knock down
Project description:The transcriptomic response of rat hepatic stellate cells to endotoxin: implications for hepatic inflammation and immune regulation
Project description:HSC-2 (hepatic stellate cells line from rat) were stably transfected with rno-miR-146a. Three different clones were selected (S1, S4, S5). We used Affymetrix rat genome RAT230 2.0 chip to monitor global transcriptome changes. Two passages of each sample were used. Control - HSC-2 and GFPscr.

Project description:Metabolomic analysis on hepatic stellate cells isolated from PBS- or thioacetamide (TAA)-treated wild-type and Cyp1b1 knockout mice was performed to determine the metabolic basis by which CYP1B1 ablation inhibits HSC activation and liver fibrosis.
Project description:In order to establish a rat embryonic stem cell transcriptome, mRNA from rESC cell line DAc8, the first male germline competent rat ESC line to be described and the first to be used to generate a knockout rat model was characterized using RNA sequencing (RNA-seq) analysis.
Project description:Analysis of LBNF1 rat testes from controls, containing both somatic and all germ cell types and from irradiated rats in which all cells germ cells except type A spermatgogonia are eliminated. Results provide insight into distinguishing germ and somatic cell genes and identification of somatic cell genes that are upregulated after irradiation.
Project description:Analysis of hepatic stellate cells (HSCs) isoltaed from ASMA-HAS2 transgenic and HSC-specific Has2 knockout mice. HAS2 synthesized hyaluronic acid, one of major extracellular matrix. Results provide insight into the role of HAS2 in hepatic stellate cells.
Project description:Normal and cirrhotic LSECs can influence hepatic stellate cells (HSCs) differently. This project aims to determine the set of proteins secreted by LSECs from healthy and cirrhotic livers, and identify the protein(s) that promote HSC activation.
