OBJECTIVE: Recent researches have proved that circular RNAs (circRNAs) act as an important role in many diseases. Our study aims to uncover the role of circ-ABCB10 in the progression of non-small cell lung cancer (NSCLC).

PATIENTS AND METHODS: Real Time-quantitative Polymerase Chain Reaction (RT-qPCR) was utilized to detect circ-ABCB10 expression in NSCLC patients. Then, we conducted Cell Counting Kit-8 (CCK-8) assay, colony formation assay, Ethynyl deoxyuridine (EdU) incorporation assay, cell cycle assay, and cell apoptosis assay in treated NSCLC cells. Besides, further experiments including RT-qPCR and Western blot assay were performed to explore the potential mechanism in vitro.

RESULTS: Circ-ABCB10 expression level was significantly higher in NSCLC samples comparing to that in adjacent tissues. Moreover, functional assays showed that the cell growth ability of NSCLC cells was inhibited after circ-ABCB10 was knocked down. In addition, the cell apoptosis of NSCLC cells was promoted after circ-ABCB10 was knocked down. Also the expression of KISS1 was upregulated by the knockdown of circ-ABCB10. Furthermore, it was found that KISS1 expression was negatively correlated to the circ-ABCB10 expression in NSCLC tissues.

CONCLUSIONS: Results above indicated that circ-ABCB10 promoted cell proliferation and inhibited cell apoptosis of NSCLC by suppressing KISS1, which suggested that circ-ABCB10 may be a potential therapeutic target in NSCLC.
