Dual-direction effect of crenulatin on apoptosis of cerebral microvascular endothelial cells and it's mechanism / 中国病理生理杂志

ABSTRACT

] AIM: To study the effect and the mechanism of crenulatin, an effective constituent of Chinese traditional medicine, on apoptosis of cerebral microvascular endothelial cells. METHODS: The following terminal concentrations of crenulatin were used in the study 25 mg/L and 100 mg/L. Apoptosis of mouse cerebral microvascular endothelial cells (bEnd.3 cell line) was evaluated by flow cytometer, immunocytochemical assay (Fas, Bcl-2) and Western blotting (caspase-3) after culture for 24 h. RESULTS: Compared with control group, apoptosis of bEnd.3 cells in 25 mg/L group was significantly inhibited (P
