摘要:

目的 探讨过表达大肿瘤抑制因子2(LATS2)基因对口腔鳞状细胞癌(OSCC)细胞增殖和凋亡的影响。方法 应用慢病毒介导的基因过表达技术,使用LATS2过表达慢病毒感染SCC-25细胞株。通过CCK-8检测过表达LATS2对细胞增殖的影响;流式细胞术检测LATS2基因过表达后细胞凋亡情况;Western blot检测LATS2过表达后对凋亡相关蛋白Bax和Bcl-2表达的变化。结果 转染pEGFP-LATS2细胞的LATS2基因表达明显上调;pEGFP-LATS2组细胞增殖明显受到抑制;流式细胞术检测pEGFP-LATS2组凋亡率明显高于空白对照组(control)和空载体组(pEGFP-control)(P<0.05)。与control和pEGFP-control组相比,pEGFP-LATS2组Bax蛋白上调,而Bcl-2蛋白下调。结论 过表达LATS2基因可明显抑制SCC-25细胞增殖并促进细胞凋亡。

Abstract:

Objective To investigate the effect of large tumor suppressor homolog 2 (LATS2) gene overexpression on the proliferation and apoptosis of oral squamous cell carcinoma (OSCC).Methods Lentivirous particles were transferred into SCC-25 cell to upregulate LATS2 gene expression. Cell proliferation was detected by CCK-8 assay. Apoptosis was detected through flow cytometry. The expression changes of Bax, Bcl-2, and LATS2 were analyzed by Western blot.Results Gene transfection increased LATS2 expression. Compared with the control group and pEGFP-control group, SCC-25 cell proliferation in the pGFP-LATS2 group was inhibited, whereas the apoptosis ratio increased (P<0.05). Bcl-2 expression decreased, and Bax expression increased.Conclusion Overexpression of LATS2 could inhibit SCC-25 cell proliferation and induce apoptosis.

Key words: oral squamous cell carcinoma, large tumor suppressor homolog 2, proliferation, apoptosis
