Biological function analysis of circ_RUNX2 in OA. (A) circ_RUNX2 has biological characteristics of resistance to RNA exonuclease. (B) Nucleocytoplasmic separation experiments confirmed that circ_RUNX2 was mainly located in the cytoplasm. (C) The potential sponged miRNAs by circ_RUNX2 in biological information analysis. *p < 0.05, **p < 0.01, ***p < 0.001
