In this study, we investigated the effects of adenovirus-mediated transfection of PC12 cells with glucose transporter 3 after ischemic injury. The results of flow cytometry and TUNEL showed that exogenous glucose transporter 3 significantly suppressed PC12 cell apoptosis induced by ischemic injury. The results of isotopic scintiscan and western blot assays showed that, the glucose uptake rate was significantly increased and nuclear factor kappaB expression was significantly decreased after adenovirus-mediated transfection of ischemic PC12 cells with glucose transporter 3. These results suggest that adenovirus-mediated transfection of cells with glucose transporter 3 elevates the energy metabolism of PC12 cells with ischemic injury, and inhibits cell apoptosis.
在本研究中,我们调查了腺病毒介导的葡萄糖转运蛋白3转染缺血损伤后的PC12细胞的效果。流式细胞术和TUNEL检测结果显示,外源性葡萄糖转运蛋白3显著抑制缺血损伤诱导的PC12细胞凋亡。同位素闪烁扫描和蛋白质免疫印迹分析结果显示,腺病毒介导的葡萄糖转运蛋白3转染缺血PC12细胞后,葡萄糖摄取率显著增加,核因子κB表达显著降低。这些结果表明,腺病毒介导的葡萄糖转运蛋白3转染细胞可提高缺血损伤PC12细胞的能量代谢,并抑制细胞凋亡。
