The present study aims to observe the effects of NCTD (norcantharidin) on proliferation and FN (fibronectin) expression in human renal proximal tubular epithelial cell line (HK‐2) induced by albumin in vitro . HK‐2 cells were divided into control group, albumin group and different concentration of NCTD intervention groups. Proliferation of HK‐2 cells was determined by MTT [3‐(4,5‐dimethylthiazol‐2‐yl)‐2,5‐diphenyl‐2 H ‐tetrazolium bromide], FN protein in culture media of HK‐2 cells was examined by ELISA, and FN mRNA was analysed by RT—PCR (reverse transcription—PCR). We chose less than 5.0 mg/l of NCTD as the experimental concentration for the cytotoxicity test. MTT score was higher in the albumin group than in the control group ( P <0.05). As compared with that of the albumin group, MTT score and FN protein concentration decreased, FN mRNA significantly down‐regulated in NCTD intervention groups respectively ( P <0.05). Our study showed that NCTD could inhibit the albumin‐induced cell proliferation and FN expression in HK‐2 cells, which might further prove the anti‐fibrotic role of NCTD in proteinuria‐associated tubulointerstitial damage.
