ABSTRACT
Objective To investigate the effects of Free fatty acids (FFAs) on extracellular matrix(ECM) mRNA expression and secretion.Methods Rat glomerular mesangial cells(HBZY-1 cells) were cultured in vitro and stimulated with OA in different concentration.The expression of collagen Ⅳ(Col Ⅳ) and fibronectin (FN) and transforming growth factor-beta1(TGF-?_1) mRNA were measured by semi-quantitative RT-PCR.The levels of Col Ⅳ and FN in cultured supernatant were determined by ELISA.Results The mRNA expression of Col Ⅳ, FN and TGF-?_1 of 25、100、400 ?mol/L stimulated OA groups were 0.94?0.17、1.16?0.15、1.28?0.19 and 0.82?0.11、0.97?0.07、1.09?0.08 and 1.15? 0.07、1.24?0.06、1.36?0.05 respectively , which increased significantly compared with their control group(0.73?0.16、0.53?0.09、 0.96?0.11 P
