MALAT1 promotes lung cancer cell proliferation by targeting and regulating miR-206 expression, activating the PI3K/Akt signaling pathway, and increasing phosphorylation of mammalian rapamycin (mTOR), ribosomal protein S6 kinase 1 (S6K1) and other related proteins (Tang et al., 2018). Here, MALAT1 is linked to lung carcinoma.
