摘要: 目的: 先前的研究发现,微管解聚蛋白(Stathmin)是潜在的指导局部晚期口腔鳞癌诱导化疗的生物标志物,本研究旨在进一步探索长春新碱对Stathmin的调控作用以及其作为TPF化疗替代药物的潜能。方法: 构建Stathmin过表达及敲减稳转细胞系,通过细胞增殖试验、q-PCR、Western免疫印迹、皮下移植瘤等实验方法,采用SPSS 23.0软件包进行统计学差异分析。结果: 长春新碱可抑制口腔鳞癌细胞系Stathmin的表达。高表达Stathmin后,口腔鳞癌细胞系对长春新碱的敏感性提高。针对高表达Stathmin的口腔鳞癌细胞系移植瘤,长春新碱具有良好的抑瘤效果。结论: 对于高表达Stathmin的口腔鳞癌,长春新碱是潜在的替代化疗药物。

Abstract: PURPOSE: Our previous studies have found that Stathmin, a microtubule depolymerizing protein, is a potential biomarker to guide locally advanced oral squamous cell carcinoma (OSCC) induction chemotherapy. This study further explored the regulatory effect of vincristine on Stathmin and its potention as an alternative chemotherapy drug. METHODS: Stathmin overexpressed and knockdown stable cell lines were constructed. Cell proliferation, q-PCR, Western blot, subcutaneous xenograft and other experimental methods were used to value the regulatory effect of vincristine on Stathmin. The differences were statistically analyzed with SPSS 23.0 software package. RESULTS: Vincristine inhibited the expression of Stathmin in OSCC cell lines. The sensitivity to vincristine was increased in Stathmin overexpressed OSCC cell lines. Vincristine had potent anti-tumor effect for OSCC cell line xenografts with higher Stathmin expression. CONCLUSIONS: Vincristine is a potential alternative chemotherapeutic agent for OSCC with higher Stathmin expression.
