Functional description
BACKGROUND: An increasing body of evidence has revealed that long non-coding RNAs play a significant part in a variety of human cancers, including lung adenocarcinoma (LUAD). METHODS: The expression of PP7080, miR-670-3p and UHRF1BP1 in LUAD cells and tissues was detected using a quantitative real-time polymerase chain reaction. The role of PP7080 in LUAD cells was validated by CCK-8, flow cytometry, colony formation, transwell and wound healing assays. The binding capacity between PP7080/UHRF1BP1 and miR-670-3p was confirmed by luciferase reporter assays. Moreover, the interactional mechanism among PP7080, miR-670-3p and UHRF1BP1 was determined by means of RNA immunoprecipitation and western blot assays. RESULTS: The expression level of PP7080 is up-regulated in LUAD cells and tissues compared to their matched controls. Down-regulation of PP7080 restrained the proliferative and migratory abilities of LUAD cells, but induced cell apoptosis. PP7080 up-regulation led to the opposite results. Moreover, the binding ability between miR-670-3p and PP7080/UHRF1BP1 in LUAD cells was confirmed. A rescue assay revealed that PP7080 contributes to LUAD development by modulating the miR-670-3p/UHRF1BP1 signaling pathway. CONCLUSIONS: PP7080 expedites the proliferation and migration of LUAD cell via sponging miR-670-3p and modulating UHRF1BP1.
