MTOR and cancer: In addition, oleacein counteracts the expression of miR-34a-5p, miR-193a-3p, miR193a-5p, miR-16-5p, and miR-155-5p, which act as regulatory elements decreasing the transcriptional levels of c-KIT, KRAS, and PIK3R3, contrasting the mTOR signaling pathway, thus reducing its growth factor-like effects on 501Mel cancer cells [146].
