Lung adenocarcinoma (LUAD) is one of the most common type of lung cancer notorious for the high incidence and mortality around the world. Long non-coding RNAs (LncRNAs) are defined as a class of RNAs with length more than 200 nucleotides. Mounting studies have proved that lncRNAs are related closely to incidence of diseases and play crucial roles in cancer progression. Although LINC01419 has been studied in several cancers, the function and mechanism of LINC01419 in LUAD remains a mystery. Our findings showed that LINC01419 level was high in LUAD cells, and LINC01419 knockdown inhibited carcinogenesis via suppressing cell proliferation, migration as well as invasion. Moreover, bioinformatics prediction, luciferase reporter experiments and RIP assay were used to confirm miR-519-3p was sequestered and negatively regulated by LINC01419. Subsequently, RCCD1 was identified as a miR-519b-3p target and had inverse relationship with miR-519b-3p. LINC01419 was positively related to RCCD1. Furthermore, rescue assays confirmed that miR-519b-3p inhibitor or RCCD1 overexpression could neutralize the effect of LINC01419 silenced in cell proliferation, migration and invasion. Taken together, all the results indicated that LINC01419 exhibited oncogenic behaviors LUAD via binding to miR-519b-3p to enhance the expression of RCCD1, manifesting the underlying therapy values of LINC01419 in LUAD.
