瓜子金皂苷己对连二亚硫酸钠致氧糖剥夺/复供诱导PC12细胞凋亡的抑制作用
Inhibitory effect of Polygalasaponin F on the apoptosis of PC12 cells induced by sodium dithionite-caused oxygen-glucose deprivation and reperfusion
摘要
Abstract
Aim To study the effect of Polygalasapo-nin F ( PGSF ) on apoptosis of PC 12 cells induced by oxygen-glucose deprivation and reperfusion ( OGD/R ) and its mechanism. Methods The OGD/R model was established by first exposing PC 12 cells to sodium di-thionite ( Na2S2O4 ) in glucose-free Earle's solution and then by changing the culture into complete mediums, with the cell injury and apoptosis analyzed by Hoechst 33342 / PI dual staining and flow cytometry assay. The mitochondrial membrane potential ( MMP ) was determined by JC-1 staining, and the expression of Bcl-2 and Bax was detected by Western blot. Results PGSF could significantly improve the morphology of injured PC 12 cells and reduce the percentage of apop-totic cells, reverse the decrease in MMP and up-regu-late the ratio of Bcl-2/Bax proteins. Conclusion PGSF can markedly inhibit the OGD/R-induced apoptosis of PC 12 cells by regulating the expression of Bcl-2 and Bax proteins and maintaining the normal MMP.关键词
