This study aims to investigate whether high glucose can activate TNF receptors to regulate endothelial progenitor cell apoptosis through oxidative stress response. Human umbilical vein endothelial cells (HUVECs) and MCF-7 breast cancer cells will be cultured and treated with different concentrations of glucose and TNF-α. MTT method will be used to evaluate cell survival rate, and western blot will be used to analyze the changes in TNFR1 and TNFR2 expression and apoptosis mechanism experiments. Preliminary results showed that high glucose significantly increased the apoptosis rate of endothelial progenitor cells and activated the expression of TNFR1 and TNFR2, which may be a mechanism by which high glucose affects the development of endothelial progenitor cells. Our experiment will further explore the detailed characteristics of this mechanism, providing a new perspective for future research on the impact of high glucose on endothelial cells.Keywords:High glucose, endothelial progenitor cells, oxidative stress, TNF receptor, apoptosis
