Abstract

Non-small cell lung cancer (NSCLC) is one of the leading causes of cancer-related death globally. This study aimed to disclose the role of circular RNA circ_0072088 in NSCLC and illustrate its potential mechanism. Quantitative real-time polymerase chain reaction (qRT-PCR) was applied to detect the expression of circ_0072088, zinc finger RNA binding protein (ZFR), microRNA-377-5p (miR-377-5p) and NOVA alternative splicing regulator 2 (NOVA2). The viability, colony formation, cell cycle, migration and invasion of NSCLC cells were measured by cell counting kit-8 (CCK8) assay, colony formation assay, flow cytometry, wound healing assay and transwell invasion assay. Western blot assay was employed to examine the protein levels of proliferating cell nuclear antigen (PCNA), Cyclin D1, matrix metallopeptidase 2 (MMP2), MMP9 and NOVA2. The downstream targets of circ_0072088 and miR-377-5p were searched through using circular RNA Interactome and TargetScan databases, and the interaction between miR-377-5p and circ_0072088 or NOVA2 was confirmed by dual-luciferase reporter assay and RNA immunoprecipitation (RIP) assay. in vivo tumor growth assay was used to evaluate the functions of circ_0072088 in the progression of NSCLC in vivo.

Alternative splicing

Alternative splicing a regulated gene expression process that allows a single genetic sequence to code for multiple proteins. Here is that latest research.

Cell Migration

Cell migration is involved in a variety of physiological and pathological processes such as embryonic development, cancer metastasis, blood vessel formation and remoulding, tissue regeneration, immune surveillance and inflammation. Here is the latest research.
