Clusterin expression and paclitaxel resistance in cervical cancer cell lines / 대한산부인과학회지

ABSTRACT

OBJECTIVE: The purpose of this study was to evaluate whether clusterin expression is significantly correlated with paclitaxel resistance in cervical cancer cell lines. METHODS: The expressions of clusterin in cervical cancer cell lines were validated with western blotting. And subsequently, the correlation between clusterin expression levels and the IC50 of paclitaxel in several cervical cancer cell lines was evaluated. After transfection of clusterin siRNA into HeLaS3, which expressed high level of clusterin, their effect on chemo-resistance was evaluated by XTT assay. RESULTS: Clusterin expression levels were correlated with paclitaxel resistance in cervical cancer cell lines. And after transfection of clusterin siRNA into HeLa-S3 significantly decreased paclitaxel resistance (P<0.05). CONCLUSION: These findings suggest that clusterin expression may correlate with paclitaxel resistance.
