Abstract:
:Circular RNAs (circRNAs) have been associated with lung cancer (LC), one of the most common cancers, but the underlying molecular mechanisms of the specific correlation with LC carcinogenesis remain unveiled. Quantitative real-time polymerase chain reaction was applied to examine the level of circZNF609. LC cells were transfected with silenced circZNF609 by siRNAs, and cell proliferation, migration, and apoptosis were evaluated to reflect the influences of circZNF609 knockdown in LC. Biotin-coupled circRNA capture, FISH and luciferase reporter assays were performed to study the relationship between circZNF609 and miR-142-3p. In current work, it was discovered that circZNF609 functioned as an onco-circRNA, which exhibited high expression as well as facilitated the proliferation and migration in LC cells. Next, we discovered that FUS RNA-binding protein, which could bind to the ZNF609 pre-mRNA, induced circZNF609 formation, and increased circZNF609 expression in LC. Furthermore, circZNF609 was verified to sponge and sequester miR-142-3p; circZNF609 enhanced LC cell proliferative and migrative ability via targeting miR-142-3p. Finally, G protein subunit beta 2 (GNB2) was figured out to involve in circZNF609/miR-142-3p axis-induced LC development. Conclusively, the results indicated that FUS-induced circZNF609 exerts promotional effects on LC cell proliferation and migration through modulation of the miR-142-3p/GNB2 axis, which could offer new insight for understanding LC.
