[The effect and mechanism of ANXA1 on TPF chemosensitivity in oral squamous cell carcinoma].

To investigate the mechanism of ANXA1 in TPF chemotherapy of oral squamous cell carcinoma (OSCC).ANXA1 overexpression and low-expression cell lines were constructed. The role of ANXA1 in TPF chemotherapy was analyzed by cell proliferation, cytotoxicity test, real-time PCR and Western blot, and the mechanism of ANXA1 in TPF chemotherapy through EMT (epithelial-mesenchymal transition) pathway was discussed. The data were analyzed with SPSS 18.0 software package.After overexpression of ANXA1, cell growth rate decreased, cell cycle slowed down, sensitivity to TPF-induced drugs decreased, and EMT occurred in OSCC. After underexpression of ANXA1, cell growth rate increased, cell cycle accelerated, sensitivity to TPF chemotherapeutic drugs increased, and reverse EMT occurred in OSCC.In TPF chemotherapy of OSCC, overexpression of ANXA1 results in EMT of cells, which leads to decreased chemosensitivity.
