Effects of emodin on the proliferation of the glomerular mesangial cell and correlative cytokines in rats

ObjectiveTo investigate the effects of emodin(EMD) on cell proliferation and correlative cytokines secretion of glomerular mesangial in rats.MethodsThe effects of EMD on cell proliferation and IL-6, TGF-β 1 secretion of glomerular mesangial in rats were observed. Cell proliferation was measured by MTT method. IL-6 and TGF-β 1 secretion was detected with ELISA.ResultsEMD was able to inhibit the cell proliferation and down-regulate the IL-6 and TGF-β 1 secretion of glomerular mesangial, as compared to the model group in rats (P < 0.05).ConclusionEMD could significantly inhibit the cell proliferation, and reduce the creation of extracellular matrix(ECM), this indicated that it could play an important role in alleviation and prevention of glomerular sclerosis. The mechanism may be that EMD can reduce the IL-6 and TGF-β 1 secretion of glomerular mesangial cell in rats.
