Abstract: Prolonged activation of dermal fibroblasts is the main cause of progressive fibrosis in systemic sclerosis (SSc). It seems that inhibition of apoptosis in SSc fibroblasts deregulates fibrosis. MicroRNA-21 (miR-21) is a pro-fibrotic factor with high expression in lesional areas of SSc skin and fibroblasts. Methods The effects of miR-21 on expression of Bcl-2 and Bax, two apoptotic genes, in dermal fibroblasts of SSc patients were evaluated using real-time polymerase chain reaction and Western blot analysis. Apoptotic ... سال انتشار: 2016

خلاصه: It is generally accepted that the apoptosis of myofibroblasts is a crucial event in the normal wound healing. Delay in myofibroblasts apoptosis results in fibrotic diseases such as systemic sclerosis (SSc). Transforming growth factor-b1 (TGF-b1) is an important cytokine to induce fibroblasts differentiation into myofibroblasts. Cellular Abelson (c-Abl) is known as a TGF-b1- modulating molecule in fibrosis. The role of c-Abl, TGFb1, and their interaction in SSc myofibroblasts apoptosis has not yet been fully explored. The aim of this ... سال انتشار: 2015
