AB  - <p>The purpose of this study was to evaluate the effects of stathmin-1 on chk1 protein expression in cervical cancer cells and the influences on the cells’ invasion and tumorigenicity. Suppressed stathmin-1 expression in Hela cells and C33A cells by lentiviral vector were utilized. Real time PCR and Western blot were used to examine the expression of chk1. Cell proliferation and invasion were studied using MTT assays and transwell migration assays.The differences of tumorigenicity in vivo were explored using xenograft experiments. In addition, stathmin-1 expressions in 24 cervical cancer patients were studied without regional lymph nodes metastasis and 16 metastatic patients by immunohistochemistry assays and real time PCR. This study found downregulating stathmin-1 reduced chk1 expressions and the proliferation and invasion in cervical cancer cells and reduced the tumorigenicity of tumor cells.</p>
