MiR-140-5p is down-regulated in synovial tissues of rats with KOA. a, the expression of miR-140-5p in synovial tissues was detected by RT-qPCR; b, the results of fluorescence microscopy observation (400 ×), * P < 0.05 vs the control group, # P < 0.05 vs the ACLT group. N = 10, the measurement data conforming to the normal distribution were expressed as mean ± standard deviation. ANOVA was used for comparisons among multiple groups. Tukey’s multiple comparisons test was used for pairwise comparisons after ANOVA.
