The aim of this research was to discuss Hederagenin's antitumor effects on glioma by in vitro study. U251 and U87 cell lines were used as research target in our research. In the first step, the different Hed concentrations were treated to U251 and U87 cell lines, and the second step is Nur77 transfection in U251 and U87 with Hed treatment; measuring cell proliferation by MTT and EdU staining; evaluating cell invasion and migration abilities by transwell assay and relative gene and protein expressions by RT-qPCR and WB assay. Compared with NC group, U251 and U87 cell proliferation were significantly depressed with cell apoptosis significantly increasing, and cell invasion and migration abilities were significantly inhibited in Hed-treated groups ( < .05, respectively); however, with Nur77 transfection, the Hed's antitumor effects disappeared. Meanwhile, with Hed supplement, Nur77, PI3K, and AKT gene expressions were significantly downregulated ( < .05, respectively) in Hed-treated groups; and Nur77, p-PI3K, and p-AKT protein expressions were significantly decreased ( < .05, respectively) in Hed-treated groups. Hed had antitumor effects on glioma cell biological activities via Nur77/PI3K/AKT pathway in vitro study.
本研究旨在通过体外研究探讨常春藤皂苷元对胶质瘤的抗肿瘤作用。本研究以U251和U87细胞系作为研究对象。第一步,用不同浓度的常春藤皂苷元处理U251和U87细胞系,第二步是在常春藤皂苷元处理的U251和U87细胞中进行Nur77转染;通过MTT和EdU染色检测细胞增殖;通过Transwell实验评估细胞侵袭和迁移能力,并通过RT-qPCR和WB实验检测相关基因和蛋白表达。与NC组相比,常春藤皂苷元处理组U251和U87细胞增殖明显受到抑制,细胞凋亡明显增加,细胞侵袭和迁移能力明显受到抑制(均P<0.05);然而,Nur77转染后,常春藤皂苷元的抗肿瘤作用消失。同时,添加常春藤皂苷元后,常春藤皂苷元处理组中Nur77、PI3K和AKT基因表达明显下调(均P<0.05);常春藤皂苷元处理组中Nur77、p-PI3K和p-AKT蛋白表达明显降低(均P<0.05)。体外研究表明,常春藤皂苷元通过Nur77/PI3K/AKT途径对胶质瘤细胞生物学活性具有抗肿瘤作用。
