"Increased expression levels of TGF-beta receptor II (TGFBR2) in MSCs from SSc patients under basal conditions and enhanced SMAD3 activation followed by increased collagen mRNA synthesis was recently independently reported upon short-term TGF-beta1 stimulation (up to 24 h) [XREF_BIBR]."

"Results indicated that knockdown of TbetaRII, confirmed by Western blotting analysis and RT-PCR (XREF_FIG), reduced both basal and TGF-beta1-induced P-Smad2 and P-Smad3 (XREF_FIG), as well as Smad responsive promoter activity as reported by luciferase activity (XREF_FIG), suggesting that autocrine TGF-beta signaling is also abrogated by TbetaRII knockdown."

"The EOB phenotype was observed in mice lacking the type I BMP receptor genes, Acvr1 and Bmpr1a, the R-Smad genes, Smad 1 and Smad5, and the Co-Smad gene, Smad 4, but not in mice lacking the type II TGFbeta receptor gene Tgfbr2 and the activin and TGFbeta activated R-Smad genes, Smad2 and Smad3."
"\"Smad proteins mediate signaling by transforming growth factor-beta (TGF-beta) 1 superfamily members (1-3). Upon binding of TGF-beta to cell surface complexes of type I and type II receptor serine/threonine kinases, the type II receptor phosphorylates the type I receptor, which further phosphorylates the receptor-regulated (R-) Smads, Smad2 and Smad3 (3). Phosphorylated R-Smads oligomerize with the common mediator (Co) Smad4 and accumulate in the nucleus where they regulate gene expression.\""

"Furthermore, acute and long-term pretreatment of ECs with thrombin or PAR1 peptide agonist suppressed the TGF-beta-induced serine phosphorylation of Smad2, a critical mediator of TGF-beta signaling. Moreover, activation of PAR1 led to a profound and spread cytosolic clustering formation of Smad2/3 and markedly prevented Smad2/3 nuclear translocation evoked by TGF-beta1."
