The activated stellate cell has been implicated in the pathogenesis of alcohol- or inflammation-mediated cirrhosis through fibrogenic proteins such as transforming growth factor-beta1; however, the role of the stellate cell in pure, noninflammatory fibrosis is unknown.
Neither decorin nor TGF-beta 1 protein deposition increased further in cirrhosis with low inflammatory activity, suggesting that impaired extracellular matrix catabolism rather than active production plays a role in this stage.
Effects of Bone Marrow-Derived Mesenchymal Stem Cells on Hypoxia and the Transforming Growth Factor beta 1 (TGFβ-1) and SMADs Pathway in a Mouse Model of Cirrhosis.
ROR-γ expression was elevated in hepatocyte cells treated with TGF-β1, and ROR-γ protein levels were elevated in the fibrotic mouse livers and human livers with cirrhosis.
Logistic regression analysis identified male sex, age, serum ferritin and TGF-beta1 codon 25 Arg/Pro and Pro/Pro as independent predictors for the presence of cirrhosis.
This study aimed to evaluate transforming growth factor-β1 (TGF-β1)-509 and tumor necrosis factor-α (TNF-α)-308 genes polymorphisms as a risk factors for cirrhosis and hepatocellular carcinoma (HCC) in chronic hepatitis C patients.
A significant decrease was found in the hepatic expression of the SHH, IHH, and TGF-β1 pathways along with the expression of TAZ in tissue specimens with simple steatosis in comparison with patients affected by NASH cirrhosis and controls.
Using Northern blot analysis, we studied the expression of TGF beta 1 messenger RNA (mRNA) in liver specimens from 42 patients with chronic hepatitis and cirrhosis and 12 subjects with either normal or fatty livers.
