Effect of drug-containing serum of Fushen Jiangzhuo formula on anti-fi-brosis factors HGF and BMP-7 in rat renal interstitial fibroblasts with re-nal tubulointerstitial lesion / 中国病理生理杂志

ABSTRACT

AIM:To study the protective effects and mechanism of Fushen Jiangzhuo formula (FSJZ) on the rat renal interstitial fibroblasts with renal tubulointerstitial lesion .METHODS:The serum containing FSJZ and blank con-trol serum were prepared .The rat model of mesangial proliferative glomerulonephritis ( MsPGN) was established and ex-tended the time of modeling to 20th weeks for developing tubulointerstitial lesion naturally .The rat renal interstitial fibro-blasts at the end of 12, 16, 20 week of modeling were isolated and cultured .The effects of FSJZ on the expression of hepa-tocyte growth factor (HGF) and bone morphogenetic protein-7 (BMP-7) at mRNA and protein levels in the pathological re-nal interstitial fibroblasts were determined .RESULTS:The anti-fibrosis factors HGF and BMP-7 were changed in patho-logical renal interstitial fibroblasts .Renal tubulointerstitial lesion significantly down-regulated the expression of HGF and BMP-7, while the drug containing serum of FSJZ significantly up-regulated the expression of HGF and BMP-7.CONCLU-SIONDrug containing serum of FSJZ has protective effect on pathological renal interstitial fibroblasts by regulating the mRNA and protein expression of HGF and BMP-7.
