ABSTRACT
<p><b>OBJECTIVE</b>To investigate the effects of fushenkeli on the expression of TAK1 in the proliferation of the renal tubular epithelial cells induced by TGF-beta1 and its possible mechanism.</p><p><b>METHOD</b>Human renal tubular epithelial (HK-2) cells were divided into five groupsblank control group, TGF-beta1 group (5 microg x L(-1)), intervention group 1 (5 microg x L(-1) of TGF-beta1 + 100 mg x L(-1) of fushenkeli), intervention group 2 (5 microg x L(-1) of TGF-beta1 + 500 mg x L(-1) of fushenkeli) and intervention group 3 (5 microg x L(-1) of TGF-beta1 + 1 g x L(-1) of fushenkeli). HK-2 proliferation was detected by methyl thiazolyl tetrazolium (MTT) assay. Type IV collagen in the supernatants of the cultured HK-2 was detected by ELISA at 12, 24, 48 hours respectively. The protein and mRNA expressions of TAK1 was measured by Western blot and real-time quantitative PCR.</p><p><b>RESULT</b>1) The cell proliferation and the expression of type IV collagen were increased compared with the control group (P<0.05, P<0.01), but they were decreased in intervention group. 2) The expressions of protein and mRNA of TAK1 in TGF-beta1 group were upregulating significantly compared with control group (P<0.01), but they were downregulating in intervention group, especially in intervention group 3.</p><p><b>CONCLUSION</b>Fushenkeli could inhibits TAK1 expression induced by TGF-beta1 in the proliferation of HK-2 cell.</p>
