Effect of curcumin-loaded solid lipid nanoparticles and DDP on proliferation and expression of Bax/Bcl-2 protein in human ovarian cell line SKOV3
Objective:To investigate the effect of curcumin-loaded solid lipid nanoparticles(SLN-Cur)in combination with cisplatin(DDP)on growth of human ovarian cancer cell line SKOV3 and its apoptosis induction.Methods:SLN-Cur was prepared in an aqueous system using curcumin as a model drug.SKOV3 cells were treated with curcumin
DDP
SLN-Cur
curcumin combined with DDP and SLN-Cur combined with DDP respectively.Cell morphology variation and cell ultrastructure were observed;the apoptosis rate of SKOV3 cell and the expression of apoptosis-associated gene proteins were detected.Results:Curcumin-loaded solid lipid nanoparticles(SLN-Cur)could effectively inhibit SKOV3 in a dose-and-time-dependent manner.The IC50 of curcumin-loaded solid lipid nanoparticles(SLN-Cur)to SKOV3 was 40.14 μmol/L in 24 hours.Simultaneous administration of SLN-Cur and DDP resulted in synergistic cytotoxicity and apoptosis for SKOV3 cells;the expression of Bcl-2 was down-regulated while the expression of Bax was up-regulated.Conclusion:The rate of cell proliferation inhibition and the rate of the SKOV3 cell line apoptosis by SLN-Cur combined with DDP are significantly higher.The apoptosis is related to the down-regulation of Bcl-2 and up-regulation of Bax.
