MLANA and neoplasm: Interestingly, it was detected that the interactions caused by the exchange of exosomes among tumor stroma and cancer cells can promote the transfer of oncomicroRNAs (e.g., miR375, miR16, miR15, miR1, and let7) as well as oncogenes (e.g., LMP-1, Melan-A/Mart-1, HER2, CEA, and β-catenin) from one cell to another, resulting in new programming in target cells [4].
