Breast‐cancer‐secreted, extracellular‐vesicle‐encapsulated miR‐105, which is induced by the oncoprotein MYC in cancer cells and in turn activates MYC signaling, through targeting MXI1 (MAX interactor 1) gene in cancer‐associated fibroblasts (CAFs) to induce a metabolic program (W. Yan et al., 2018). This evidence concerns the gene MYC and cancer.
