摘要: 背景与目的:研究表明垂体瘤转化基因1(pituitary tumor-transforming gene 1,PTTG1)在多种癌症中高表达。该研究旨在探讨其对胶质瘤细胞SHG44增殖、凋亡、迁移和侵袭能力的影响。方法:用PTTG1 siRNA干扰胶质瘤细胞SHG44的基因表达,通过实时荧光定量聚合酶链反应(real-time fluorescence quantitative polymerase chain reaction,RTFQ-PCR)和蛋白质印迹法(Western blot)分别在mRNA和蛋白质水平上评估PTTG1沉默效率,进一步检测其对SHG44细胞增殖、凋亡、迁移和侵袭能力的影响。结果:沉默PTTG1基因表达可以显著抑制SHG44细胞增殖(P<0.05)、迁移(P<0.01)和侵袭(P<0.001)能力,增加细胞凋亡(P<0.05)。结论:下调PTTG1的表达可以降低神经胶质瘤的恶化程度,有望成为临床胶质瘤治疗的新靶点。

Abstract: Background and purpose: Some studies have showed that pituitary tumor-transforming gene 1 (PTTG1) is highly expressed in many cancers. This study aimed to investigate the effects of PTTG1 on the proliferation, apoptosis, migration and invasion of glioma cells SHG44. Methods: PTTG1 siRNA was used to interfere with the gene expression of SHG44 in glioma cells. Real-time fluorescence quantitative polymerase chain reaction (RTFQ-PCR) and Western blot were used to evaluate the PTTG1 silencing efficiency at mRNA and protein levels. Furthermore, we tested the effects of PTTG1 on proliferation, apoptosis, migration and invasion of SHG44 cells. Results: The results showed that silencing PTTG1 gene expression significantly inhibited the proliferation (P<0.05), migration (P<0.01) and invasion (P<0.001) ability of SHG44 cells, and increased its apoptosis (P<0.05). Conclusion: Decreasing the expression of PTTG1 can inhibit the degree of glioma deterioration, and it is expected to become a new target for the treatment of glioma.
