ABSTRACT
<p><b>OBJECTIVE</b>To investigate the effects of saikosaponin-d (SSd) on glomerular mesangial cells (MCs) proliferation and hyperplastic extracellular matrix (ECM) induced by lipopolysaccharide (LPS) to provide experimental proof for its use in prevention and treatment of glomerulosclerosis.</p><p><b>METHODS</b>Rat's MCs were cultivated and identified. The cultured MCs were stimulated by LPS and incubated with different concentrations of SSd. Cell proliferation was determined by MTT assay, LDH assay and flow cytometry, respectively. Type IV collagen (Col IV), fibronectin (FN) and transforming growth factor beta1 (TGF-beta1) in the conditioned medium were measured by ELISA. The expressions of cyclin-dependent kinase 4 (CDK4), c-Jun and c-Fos were detected by immunohistochemistry.</p><p><b>RESULTS</b>After treated by SSd, MC proliferation was inhibited, cells in G0/G1 phase increased, and apoptosis induced. Moreover, secretion of Col IV, FN and TGF-beta1 and the expressions of CDK4, c-Jun and c-Fos in MC were inhibited.</p><p><b>CONCLUSION</b>The inhibitory action of SSd on glomerulosclerosis was realized through inhibiting the expressions of CDK4, c-J un and c-Fos.</p>
