Expression of long non-coding RNA SFTA1P and its function in non-small cell lung cancer.

This study aims to explore the clinical roles, biological function, and mechanism of SFTA1P in NSCLC. SFTA1P expression was estimated by the quantitative real-time polymerase chain reaction (qRT-PCR) of 90 pairs of tissue samples, the Cancer Genome Atlas (TCGA) database and microarray. After overexpressing SFTA1P, NSCLC cell proliferation, cycle, and apoptosis were detected. We found that the expression of SFTA1P was significantly downregulated in NSCLC tissues with high diagnostic value (AUC = 0.87), which was consistent with the results of TCGA and microarray data. For the analysis of clinical features, the results revealed that SFTA1P expression was closely related to the pathological type (P < 0.01). Furthermore, the cell function results suggested that the overexpression of SFTA1P triggered cell cycle arrest in the S-phase (P < 0.05). From a mechanistic perspective, the results showed that the PI3K-AKT signaling pathway was inhibited after overexpression of SFTA1P in NSCLC. Taken together, this work supported that SFTA1P may play a suppressing role in the tumorigenesis of NSCLC by modulating PI3K-AKT signaling pathway to influence cell cycle, which provides a potential and prospective biomarker for NSCLC.
