Abstract:
Aim To investigate the effects of Curcumin on Heme oxygenase isozymes in SH-SY5Y cells and explore a new mechanism of Curcumin in neuroprotection. Methods The human SH-SY5Y cells were cultured in vitro and treated with Curcumin at 0,1.25,5.0,20 ?mol?L-1 for 24 h,or with Curcumin at 5.0 ?mol?L-1 for 0,12,24,and 48 h. The active oxygen was detected by fluorescent probe DCFH-DA and fluorospectro-photometer. RT-PCR was used to detect the expression of HO-1 and HO-2 mRNA. Western blot was performed to detect the levels of HO-1 and HO-2 protein.Results The results showed that Curcumin could inhibit the levels of active oxygen(P
