Effect of angiotensin-(1-7) and angiotensin II on the proliferation and activation of human endometrial stromal cells in vitro.
International journal of clinical and experimental pathology(2015)
Abstract
Recent studies have shown that angiotensin II (Ang II) or angiotensin-(1-7) [Ang-(1-7)] has effect on the proliferation and activation of a variety of cells, however, the exact mechanisms that the role of Ang II or Ang-(1-7) in human endometrial stromal cell (ESCs) remains elusive. Here we demonstrated that Ang II could promote proliferation and activation of ESCs, up-regulated the expression of a-SMA, TGF-β1 and IGF-I, increased the secretion of extracellular matrix [Type I collagen (Col I) and fibronectin (FN)] of ESCs; Ang-(1-7) could inhibit Ang II induced the proliferation and activation of ESCs, down-regulated the expression of a-SMA, TGF-β1 and IGF-I, decreased the secretion of extracellular matrix (Col I and FN) of ESCs. These findings suggest that Ang-(1-7) can inhibits Ang II induced the proliferation of ESCs, Ang-(1-7) can inhibits the Ang II induced activation of ESCs and decreases secretion of Col I and FN by suppressing TGF-β1 and IGF-I expression.
