AA was tested by Cheng et al. [57] as an MDR modulator in MDR1- overexpressing cisplatin (DDP)-resistant A549/DDP lung cancer cells where the phytocompound significantly increased the cytotoxicity of cisplatin against cisplatin-resistant cells without having any impact on the cisplatin treatment of chemosensitive A549 cells. The gene discussed is ABCB1; the disease is lung cancer.
