Moreover, Aqil et al. [201] have previously shown that exosomes in combination with anthocyanins at a concentration of 75 μM increase the potential of these phenolics to arrest the growth of A2780, A2780/CP70, OVCA432, and OVCA433 ovarian cancer cells, decrease the P-glycoprotein expression, and reduce the effective cisplatin concentration required to inhibit cisplatin-resistant ovarian cancer cells, after 3 days of treatment. This evidence concerns the gene ABCB1 and ovarian cancer.
