| 摘 要： | 试验旨在研究结核分枝杆菌Rv2626c蛋白对小鼠巨噬细胞RAW264.7细胞凋亡的影响。根据GenBank数据库中结核分枝杆菌Rv2626c基因序列设计引物,并以结核分枝杆菌国际标准株H37Rv cDNA为模板,PCR扩增Rv2626c基因并克隆至慢病毒表达载体pLEX-EGFP中,包装慢病毒并感染RAW264.7细胞,使用Western blotting和流式细胞仪技术检测Rv2626c蛋白表达水平和RAW264.7细胞凋亡率变化。结果显示,成功构建慢病毒表达载体pLEX-EGFP-Rv2626c;成功包装慢病毒并感染RAW264.7细胞;Rv2626c蛋白在RAW264.7细胞中高水平表达显著促进了细胞凋亡。本试验结果表明,在RAW264.7细胞中过表达结核分枝杆菌Rv2626c蛋白能显著性增加其凋亡水平。

| Abstract: | The assay was aimed to study the effects of Mycobacterium tuberculosis Rv2626c protein on RAW264.7 cell apoptosis.According to the Rv2626c gene sequence of Mycobacterium tuberculosis in GenBank database, Rv2626c primers were designed.The Rv2626c gene was amplified and cloned into the lentiviral vector pLEX-EGFP.After transfection of lentivirus expressing vector with the helper plasmids into HEK-293T cells, lentivirus were packaged and infected into RAW264.7 cells.Then total protein of the infected cells was extracted.Protein levels of Rv2626c and apoptosis levels of RAW264.7 cells were detected using Western blotting and flow cytometry.The results showed that reconstructed lentivirus expressing vector pLEX-EGFP-Rv2626c and the Rv2626c-overexpressing lentivirus Rv2626c-lv were constructed successfully.The overexpressed Rv2626c protein promoted the RAW264.7 cells apoptosis.Overexpression of Mycobacterium tuberculosis Rv2626c protein significantly promoted apoptosis in RAW264.7 cells. |
