Effect of IL-1β on the gene expressions in chondrocytes. A Comparison of PVT1 expression between control and IL-1β-stimulated chondrocytes. B Comparison of miR-140 expression between control and IL-1β-stimulated chondrocytes. C Comparison of ADAMTS-5 and MMP-13 expression between control and IL-1β-stimulated chondrocytes. The results were represented as mean ± SD. *P < 0.05; **P < 0.01 vs control
