Abstract:
Objective To observe the protective effects of various extracts from Flos Daturae (FD), including active fraction (AF-FD), withanolides constituents (WC-FD), and flavonoids constituents (FC-FD) on Chinese hamster ovary (CHO) cells against cytotoxicity induced by DMSO. Methods The survival rate of CHO cells was examined by MTT assay and LDH leakage assays. Results Using MTT assay, coincubation of CHO cells with 3% DMSO for 24 h resulted in a significant reduction of survival rate of CHO cells. AF-FD was tested in a range of 10—80 ?g/mL to improve the survival rate of CHO cells in a dose-dependent manner. FC-FD (2.5—20 ?g/mL), but not WC-FD (30—120 ?g/mL), could significantly relieve the injury induced by 3% DMSO in CHO cells. In the measurement of LDH leakage, coincubation of CHO cells with 4.5% DMSO for 24 h obviously increased LDH release. However, all the compounds tested, including AF-FD (10—80 ?g/mL), WC-FD (30—120 ?g/mL), and FC-FD (2.5—20 ?g/mL) had no effect on LDH leakage induced by 4.5% DMSO. Conclusion The findings suggest that the FC-FD may protect CHO cells from DMSO cytotoxicity assessed by MTT assay, which may be associated with improving mitochondrial function, but not protecting the membrane injury of CHO cells.
