ABSTRACT
OBJECTIVE@#To observe the effect of norcantharidin (NCTD) on the expression of mRNA and protein of fibronectin (FN), collagen IV(Col IV) and transforming growth factor-β1(TGF-β1) in human kidney proximal tubular epithelial (HK)-2 cells induced by high glucose.@*METHODS@#HK-2 cells were incubated with serum-free DMEM for 24 h to synchronize cell growth, and then the cells were divided into 4 groups Group C (5.5 mmol/L D-glucose), Group M (5.5 mmol/L D-glucose + 24.5 mmol/L-mannitol), Group HG (30 mmol/L D-glucose), and Group HG + NCTD (30 mmol/L D-glucose + 0.5-40 mg/L NCTD). Cytotoxicity of HK-2 cells induced by high glucose of NCTD was detected by Trypan blue dye exclusive assay. The effect of NCTD on the proliferation of HK-2 cells in high glucose was determined by MTT. The cells were collected to extract total RNA and protein at 6, 24 and 48 h after the incubation. The expression of FN, Col IV and TGF-β1 mRNA was examined by RT-PCR, and FN, Col IV and TGF-β1 protein was analyzed by Western blot.@*RESULTS@#Trypan blue dye exclusive assay showed NCTD concentrations over 5 mg/L were rather toxic in HK-2 cells. The proliferation of HK-2 cells in high glucose was interrupted by interfered with 5 mg/L NCTD as measured by MTT (P0.05).@*CONCLUSION@#NCTD can downregulate FN, collagen IV and TGF-β1 mRNA and protein expression in HK-2 cells stimulated by 30 mmol/L D-glucose.
