For example, the lncRNA CCAT1 upregulates the proliferation and invasion of melanoma cells by inhibiting miR-33a (64), the lncRNA XIST regulates AKT expression by competitively binding miR-494 (65), and the lncRNA TUG1 binds to microRNA-9 to regulate the expression of Bcl2l11 (66). This evidence concerns the gene BCL2L11 and melanoma.
