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.
