Abstract
The effects of oleanolic acid (OA) on ABCB1 and ABCC1 activities were studied in a cell line constitutively expressing both proteins. It was observed that OA did not alter ABCB1 activity, but inhibited the activity of ABCC1 protein. This inhibition was reversible and only occurred in the presence of OA. In addition, OA did not alter the expression of ABCC1 mRNA. These results suggest that OA could be a good choice in the treatment of MDR tumours, either as a chemotherapic itself in tumours bearing ABCB1, or as an adjuvant in the chemotherapy of ABCC1 expressing tumours.Entities:
