MiR 26a as a stage-dependent biomarker and therapeutic regulator of inflammation in knee osteoarthritis

Figure 2 MiRNA-26a2 and 26a5 influencing the osteoarthritis genes in study groups. A: NF-κB expression; B: MMP 13 expression; C: COX expression; D: NOS expression. Control (n = 50); grade 1 (n = 16); grade 2 (n = 22); and grade 3 (n = 12) t test was significant at ^aP ≤ 0.05, ^bP < 0.01 and ^cP < 0.001.
