3 Tacrolimus (FK506) ointment has been reported to be effective for treating AD as well as some TGF-beta1-induced fibrotic diseases. Tacrolimus transforming growth factor beta 1 Homo sapiens
4 OBJECTIVES: To evaluate the effect of tacrolimus on TGF-beta1-stimulated cultured normal human dermal fibroblasts and explore the potential signalling pathways involved. Tacrolimus transforming growth factor beta 1 Homo sapiens
5 RESULTS: Our results revealed that the increased expressions of transforming growth factor-beta receptor I (TGF-betaRI) and TGF-betaRII in TGF-beta1-treated fibroblasts were suppressed by tacrolimus treatment. Tacrolimus transforming growth factor beta 1 Homo sapiens
6 In addition, tacrolimus significantly inhibited fibroblast proliferation enhanced by TGF-beta1. Tacrolimus transforming growth factor beta 1 Homo sapiens
7 TGF-beta1 increased type I collagen production, and this enhancing effect was suppressed by tacrolimus. Tacrolimus transforming growth factor beta 1 Homo sapiens
8 The down-regulation of MMP-1 and up-regulation of TIMP-1 induced by TGF-beta1 were reversed by tacrolimus. Tacrolimus transforming growth factor beta 1 Homo sapiens
9 The increase in phosphorylated p38 mitogen-activated protein kinase (p38MAPK) expression stimulated by TGF-beta1 was down-regulated by tacrolimus. Tacrolimus transforming growth factor beta 1 Homo sapiens
