CircPUM1 promotes cell growth and glycolysis in NSCLC via up-regulating METTL3 expression through miR-590-5p.

ABSTRACT: RNA pumilio RNA binding family member 1 (circPUM1) has been reported to play important roles in the tumorigenesis of several cancers. However, the underlying molecular role of circPUM1 in non-small cell lung cancer (NSCLC) progression remains unknown. The qRT-PCR and western blot were used to evaluate the expression of RNAs and proteins. In vitro cell proliferation assays, flow cytometric and glucose metabolism analyses were performed to test the effects of circPUM1 and its target on NSCLC cell growth and glycolysis. The interaction between microRNA (miR)-590-5p and circPUM1 or methyltransferase like 3 (METTL3) was analyzed by using dual-luciferase reporter, pull-down or RNA immunoprecipitation (RIP) assays. Murine xenograft model was established to conduct in vivo experiments. CircPUM1 wa
