Journal ArticleDOI
Id1 is a critical mediator in TGF-β–induced transdifferentiation of rat hepatic stellate cells†

TL;DR: In conclusion, Id1 is identified as TGF‐β/ALK1/Smad1 target gene in HSCs and represents a critical mediator of transdifferentiation that might be involved in hepatic fibrogenesis.
Journal ArticleDOI
Expression patterns of PDGF-A, -B, -C and -D and the PDGF-receptors α and β in activated rat hepatic stellate cells (HSC)
Katja Breitkopf,Claudia R.C. van Roeyen,Iris Sawitza,Lucia Wickert,Jürgen Floege,Axel M. Gressner +5 more
TL;DR: Investigating the mRNA expression profiles of all four PDGF isoforms in transdifferentiating primary cultured hepatic stellate cells found that PDGF receptor-beta (PDGFR-beta) mRNA was rapidly upregulated within the first day of culture and was constantly expressed from day 2 on while the expression profile of PDG FR-alpha mRNA was very similar to that of PDGF-A during transdifferentiation.
Journal ArticleDOI
Glucocorticoids decrease the bioavailability of TGF-β which leads to a reduced TGF-β signaling in hepatic stellate cells
TL;DR: The data suggest that glucocorticoids inhibit TGF-beta expression, prevent T GF-beta from efficient secretion, and finally lead to reduced TGF -beta signaling in primary HSC.
Journal ArticleDOI
Corticosteroids stimulate selectively transforming growth factor (TGF)-β receptor type III expression in transdifferentiating hepatic stellate cells
TL;DR: The increase of T beta RIII by corticosteroids indicates that these hormones are important regulators of this receptor and thereby they can modulate TGF-beta signaling.
Journal ArticleDOI
Glucocorticoids activate TGF-β induced PAI-1 and CTGF expression in rat hepatocytes
TL;DR: Evidence is provided that beside the TGF-β-Smad 3 pathway CTGF and PAI-1 expression is additionally dependent on Erk activity in hepatocytes giving new insights into regulation of the profibrogenic proteins.
