Description
Abstract
. Background. MiR-486-5p expression is restrained in lung adenocarcinoma (LUAD). However, much less has been understood on its role in LUAD. We aimed to explore the biofunctions of miR-486-5p in LUAD. Methods. A differential expression analysis based on The Cancer Genome Atlas-LUAD dataset was done to screen the differently expressed miRNAs and mRNAs. MiR-486-5p and SAPCD2 mRNA expression was analyzed by qRT-PCR, and protein level of SAPCD2 was assayed by western blot. Upregulation and downregulation of miR-486-5p or SAPCD2 were achieved by cell transfection. For cell function assays, the proliferation of cancer cells was examined by MTT assay. Cell apoptosis was assessed by flow cytometry and microscopy. Transwell assay was applied to evaluate cell migration and invasion. A dual-luciferase detection was employed to determine the miRNA-mRNA targeting relationship. Results. MiR-486-5p expression was notably reduced in LUAD tissue and cell lines. Upregulating miR-486-5p restrained the anti-apoptotic and proliferative abilities, as well as cell migratory and invasive phenotypes in LUAD cells. SAPCD2 was determined as one target of miR-486-5p. Also, SAPCD2 forced expression was able to attenuate the inhibitory impacts of miR-486-5p on the malignant phenotypes of LUAD cells. Conclusion. MiR-486-5p suppressed cell malignant progression in LUAD by targeting SAPCD2, suggesting that the two may be targets for LUAD treatment.
