ABSTRACT
Dysregulation of circular RNAs (circRNAs) has been observed in multiple diseases including rheumatoid arthritis (RA), and we investigated the role of the circ_0088194/microRNA (miR)-30a-3p/a disintegrin and metalloproteinase 10 (ADAM10) axis in RA. Circ_0088194, miR-30a-3p, and ADAM10 contents in RA tissues and RA-fibroblast-like synoviocytes (RA-FLSs) were analyzed by real-time quantitative polymerase chain reaction (RT-qPCR) and western blot. Cell proliferation, migration, apoptosis, and inflammatory factor secretion of RA-FLSs were detected using 5-ethynyl-2'-deoxyuridine (EdU), wound healing assay, flow cytometry, and enzyme-linked immunosorbent assay (ELISA). Targeting relationship between miR-30a-3p and circ_0088194 or ADAM10 was validated by luciferase reporter system, RNA immunoprecipitation (RIP), and RNA pull-down assays. Circ_0088194 and ADAM10 levels were increased, while miR-30a-3p was decreased in RA tissues and RA-FLSs. Circ_0088194 knockdown suppressed the growth, migration, and inflammation of RA-FLSs, while the upregulation of circ_0088194 showed opposite effects. Circ_0088194 directly targeted miR-30a-3p, ADAM10 was a target of miR-30a-3p, and circ_0088194 regulated the expression of ADAM10 by sponging miR-30a-3p. MiR-30a-3p inhibition restored the inhibition effects of circ_0088194 knockdown or RA-FLSs. Moreover, miR-30a-3p re-expression repressed growth, migration, and inflammatory response in RA-FLSs, which were reversed by ADAM10 overexpression. Circ_0088194 acted on miR-30a-3p/ADAM10 axis to promote the proliferation, migration, and inflammatory response, and inhibit apoptosis in RA-FLSs.
