Melanoma treatment with the BRAF V600E inhibitor vemurafenib (VMF) provides therapeutic benefits but the common emergence of drug resistance remains a challenge. We generated A375 melanoma cells resistant to VMF with the goal of investigating changes in miRNA expression patterns that might contribute to resistance. Increased expression of miR-204-5p and miR-211-5p occurring in VMF-resistant cells was determined to impact VMF response. Their expression was rapidly affected by VMF treatment through RNA stabilization. Similar effects were elicited by MEK and ERK inhibitors but not AKT or Rac inhibitors. Ectopic expression of both miRNA in drug-naive human melanoma cells was sufficient to confer VMF resistance and more robust tumor growth in vivo. Conversely, silencing their expression in resistant cells inhibited cell growth. Joint overexpression of miR-204-5p and miR-211-5p durably stimulated Ras and MAPK upregulation after VMF exposure. Overall, our findings show how upregulation of miR-204-5p and miR-211-5p following VMF treatment enables the emergence of resistance, with potential implications for mechanism-based strategies to improve VMF responses.
