LncRNA STARD13-AS blocks lung squamous carcinoma cells growth and movement by targeting miR-1248/C3A.

BACKGROUND: This research aims to illustrate the effect of lncRNA StAR Related Lipid Transfer Domain Containing 13 antisense RN (STARD13-AS)/miR-1248/C3A on lung squamous carcinoma cells growth and metastasis. METHODS: Bioinformatics analysis was applied to detect the expression of STARD13-AS/miR-1248/C3A in lung cancer samples and establish the ceRNA network. Transfection was performed to construct over-expression or knockdown models. PCR was implemented to examine the transfection efficiency. The biological function including growth, invasion and migration of LUSC cells were estimated by CCK-8 analysis, colony formation assay and transwell assay. Luciferase assay was executed to analyze the relationship between C3A and miR-1248, as well as miR-1248 and STARD13-AS. RESULTS: By consulting the TCGA database and GEPIA website, we found that C3A expression was significantly reduced in LUSC samples. Additionally, we also discovered that miR-1248, which was a downstream target of STARD13-AS, was presented as an upstream regulator of C3A. Moreover, STARD13-AS was under expressed in LUSC cells and has a negative effect on LUSC cells growth ability. C3A expression was co-regulated by miR-1248 and STARD13-AS. Importantly, the inhibitory effect of C3A or the promoting effect of miR-1248 on LUSC cells growth, invasion and migration abilities can be regulated by STARD13-AS. CONCLUSIONS: Our findings revealed that overexpression of STARD13-AS restricted the growth and aggressiveness of LUSC cells via regulating miR-1248/C3A.
