Effect of atragalus membranaceus combined fosinopril on NF- κB activity and OPN expression in overload albumine stimulating proximal tubular cells / 中国医师杂志

ABSTRACT

Objective To explore whether or not the function of atragalus membranaceus combined fosinopril on decreasing NF- κB activity and OPN expression in overload albumin stimulating proximal tubuler cells. Methods Cultured cells without stimulation were used as placebo. Cultured cells were incubated with bovine serum albumin fat acid free (BSA) 20mg/ml as the control. Cultured cells were incubated with fosinopril for different hours as the treatment. Cultured cells were incubated with atragalus membranaceus combined fosinopril for different hours as the atragalus membranaceus group. ELISA and RT-PCR were used to observe NF -κB activity and OPN expression after cultured for 12h, 24h. Result Atragalus membranaceus combined fosinopril rapidly decreased NFκB activity and OPN expression. Compared with the other groups, the difference was significant. Conclusion Astragalus membranaceus combined fosinopril can obviously decrease NFκB activity and OPN expression in overload albumine stimulating proximal tubular cells.
