Protective effect of rosiglitazone on cyclosporine A-induced nephrotoxicity in rat NRK cells / 中华肾脏病杂志

ABSTRACT

Objective To investigate the protective effects of rosiglitazone (RSG) on normal rat kidney cells (NRK) damaged by cyclosporine A(CsA). Methods The NRK cells were cultured with CsA or with CsA plus rosiglitazone. The cellular proliferation was determined by MTT colorimetry. The mRNA expression of TGF-?1 and PPAR? was detected by RT-RCR. Protein levels of PPAR?, p-ERK,FN and AT1R were examined by Western blotting. The level of TGF-?1 in the supernatants was measured by enzyme-linked immunosorbant assay (ELISA). Results CsA inhibited the proliferation of NRK cells in dose and time dependent manner (P
