Increasing evidences have underlined the importance of long non-coding RNAs (lncRNAs) in human malignancies. LINC00958 has been found involved in some cancers. However, the underlying mechanical performance of LINC00958 in lung adenocarcinoma (LAD) has not been explored yet.
Methods
The expression of relevant mRNA and protein were measured by qRT-PCR and western blot assays. EdU, colony formation, TUNEL and transwell assays were performed to investigate the function of LINC00958 on LAD progression. Luciferase reporter, RNA pull down and RIP assays were conducted to investigate the molecular mechanism of relevant RNAs.
Results
LINC00958 was found notably overexpressed in LAD, which was associated with the stimulation of its promoter activity induced by SP1. LINC00958 depletion dramatically inhibited LAD cell proliferation, migration and invasion capacities by acting as a miR-625-5p sponge. MiR-625-5p curbed LAD progression via targeting CPSF7 and down-regulating its expression. Mechanically, LINC00958 was identified as a competing endogenous RNA (ceRNA) and positively regulated the expression of CPSF7 via sponging miR-625-5p.
Conclusions
LINC00958 might drive LAD progression via mediating miR-625-5p/CPSF7 axis, indicating the potential of targeting LINC00958 for the treatment of LAD.
