LINC00459 sponging miR-218 to elevate DKK3 inhibits proliferation and invasion in melanoma.

ABSTRACT: The lncRNA biomarkers in melanoma remain to be further explored. The lncRNAs with different expression levels in melanoma tissue were identified by microarray analysis. To investigate the biological functions of target lncRNA, several in-vivo and in-vitro studies were performed. Potential mechanisms of competitive endogenous RNAs (ceRNAs) were predicted by using bioinformatics analysis and explored by western blot assay, fluorescence in situ hybridization assay, real-time quantitative PCR (RT-qPCR) array, RNA pull-down analysis, AGO2-RIP assay, and dual-luciferase reporter assay. The results demonstrated decreased LINC00459 in melanoma cell lines and tissues. According to the in-vitro and in-vivo experiments, up-regulated LINC00459 had inhibitory effect on cell proliferation and invasion.
