Abstract
To study the effects of astragaloside-IV (As-IV) on the expression of inflammatory factor and proliferation of glomerular mesangial cells (GMCs) induced by angiotensin Ⅱ(AngⅡ). The in vitro model of diabetic nephropathy(DN) was mimic by angiotensin Ⅱ (10-6mol/L)inducing GMCs injury. Then the GMCs were treated with As-IV at different concentrations(25,50,100 μmol/L)for 48 hours. The proliferation of GMCs was detected by MTT. The level of reactive oxidative species (ROS) was measured by flow cytometry. The expression of monocyte chemoattractant protein-1(MCP-1) protein in supernatant was detected by enzyme- linked immunosorbent assay (ELISA). The expression of transforming growth factor-β1(TGF-β1) in GMCs was measured by Western blot. Compared with model group, the proliferation of GMCs was inhibited in As-IV group. As-IV decreased the level of intercellular ROS, down-regulated the secretion of MCP-1 and the expression of TGF-β1 proteins. As-IV could inhibit cell proliferation and inflammatory factors expression on GMCs induced by AngⅡ.
