Inhibition of ALDH1A1 activity decreases expression of drug transporters and reduces chemotherapy resistance in ovarian cancer cell lines

摘要

The high mortality of ovarian cancer patients results from the failure of treatment caused by the inherent or acquired chemotherapy drug resistance. It was reported that overexpression of aldehyde dehydrogenase A1 (ALDH1A1) in cancer cells can be responsible for the development of drug resistance. To add the high expression of the drug transporter proteins the ALDHA1 is considered as a molecular target in cancer therapy. Therefore, we analysed drug-resistant ovarian cancer cell lines according to ALDHA1 expression and the association with drug resistance.
