Circ_0136474 and MMP-13 suppressed cell proliferation by competitive binding to miR-127-5p in osteoarthritis.

ABSTRACT: Osteoarthritis (OA) is a prevalent degenerative joint disease whose pathogenesis remains unclear. The research aims to investigate the roles of Circ_0136474/miR-127-5p/MMP-13 axis in OA. Differentially expressed circRNAs and miRNAs in OA cartilage tissue were screened out and visualized by R project based on RNA-seq data and microarray data respectively. qRT-PCR was carried out for detection of relative expression levels of Circ_0136474, miR-127-5p, MMP-13 and other inflammatory factors and Western blot analysis was conducted to detect the protein expression level of MMP-13. CCK-8 assay and flow cytometry were conducted to determine cell proliferation and cell apoptotic ability respectively. RNA-fluorescence in situ hybridization (RNA-FISH) experiments were conducted to confirm the immune-
