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.
