Role of nanomedicine in reversing drug resistance mediated by ATP binding cassette transporters and P-glycoprotein in melanoma

Multidrug resistance (MDR) is one of the most common complex phenomenons exhibited by cancer cells. It is a very common property of melanoma postchemotherapy. MDR transporters, ATP binding cassette (ABC) transporters, play a critical role in conferring this property to melanoma cells. miRNA are post-transcriptional regulators that regulate the expression of these ABC transporters. Targeting these miRNA, in turn targeting ABC transporters with the help of nanodelivery systems to overcome drug resistance, is the primary focus for attaining successful treatment methods for drug-resistant melanoma. These delivery systems are endocytosed by the cancer cells and do not require ABC transporters for their delivery, being a promising therapeutic measure for melanoma.
