The Melanocyte Lineage Factor miR-211 Promotes BRAFV600E Inhibitor Resistance

Resistance to targeted therapy and immunotherapy remains a major obstacle in improving care for patients with advanced melanoma. MicroRNAs play important roles in regulating gene networks involved in disease progression and resistance to therapy in cancers such as melanoma. MicroRNA miR-211 contributes to melanocyte and melanoma biology and has been implicated in targeted therapy resistance. Lee et  al. (2020) report a novel mechanism by which miR-211 promotes resistance to BRAFV600E inhibitor therapy via the upregulation of the extracellular signal–regulated kinase 5 signaling pathway.
