摘要: 目的 探究多烯磷脂酰胆碱(PPC)对高糖诱导人脐静脉内皮细胞(HUVECs)的功能损伤是否有修复作用。方法 MTT法检测PPC对高糖损伤的HUVECs增殖活力的影响。细胞划痕实验和Transwell小室法检测PPC对高糖损伤HUVECs细胞迁移能力的影响。血管形成实验检测PPC对高糖损伤HUVECs分化成血管能力的影响。Western blot检测PPC对高糖损伤的HUVECs中Bax、Bcl-2、caspase-3、VEGFA蛋白表达的影响。结果 MTT实验结果显示,PPC可以显著恢复高糖对HUVECs的增殖抑制作用。细胞划痕实验和Transwell小室法结果显示,PPC可以显著促进高糖损伤HUVECs迁移能力的恢复。血管形成实验结果显示,PPC可以显著促进高糖损伤HUVECs分化形成血管能力的恢复。Western blot结果显示,PPC可以抑制高糖损伤HUVECs内促凋亡蛋白Bax、caspase-3的表达,并促进抗凋亡蛋白Bcl-2的表达。此外,PPC显著促进高糖损伤HUVECs中VEGFA的表达。结论 PPC通过促进VEGFA的表达进而促进高糖损伤HUVECs的增殖、迁移和分化成血管能力的恢复,并且通过Bax/Bcl-2/caspase-3信号通路抑制高糖损伤HUVECs发生细胞凋亡。

Abstract: Objective Exploring whether polyene phosphatidylcholine (PPC) has a reparative effect on high glucose-induced functional damage of human umbilical vein endothelial cells (HUVECs). Methods MTT assay was used to detect the effect of PPC on the proliferation activity of HUVECs damaged by high concentration of glucose. Cell scratch assay and Transwell migration assay were used to investigate the effect of PPC on the migration ability of high glucose damaged HUVECs. The angiogenesis experiment was conducted to investigate the effect of PPC on the ability of high concentration glucose-induced HUVECs to differentiate into blood vessels. Western blot was used to detect the effect of PPC on the expression of Bax, Bcl-2, caspase-3, and VEGFA proteins in HUVECs damaged by high concentration of glucose. Results PPC significantly restored the inhibitory effect of glucose on HUVECs proliferation and significantly promoted the recovery of high glucose-damaged HUVECs migration ability. PPC also significantly promoted the recovery of the ability of high glucose-damaged HUVECs to differentiate and form blood vessels. Western blot results showed that PPC inhibited the expression of proapoptotic proteins Bax and caspase-3 in HUVECs tissue. Conclusions PPC promotes the proliferation, migration, and vascular differentiation of high glucose-induced HUVECs by increasing VEGFA expression and inhibits apoptosis of HUVECs damaged by high concentration of glucose through Bax/Bcl-2/caspase-3 signaling pathway.
