Effect of undenatured type II collagen (UC-II) on knee joint protein expression of interleukin-1β (IL-1β; A), interleukin-6 (IL-6; B), tumor necrosis factor α (TNF-α; C), interferon regulatory factor 7 (IRF7; D), cyclooxygenase-2 (COX-2; E), nuclear factor-kappa B kinase subunit gamma (IKK-γ; F), monocyte chemoattractant protein-1 (MCP-1; G), and nuclear factor kappa B (NF-κB; H) levels in monosodium iodoacetate (MIA) induced osteoarthritis rats (n = 7). The densitometric analysis of the relative intensity according to the control group of the western blot bands was performed with β-actin normalization to ensure equal protein loading. Blots were repeated at least three times (n = 3) and representative blots are shown. The bars represent the mean and standard deviation of data. ANOVA and Tukey's post-hoc test were used to compare the results among different treatment groups. Statistical significance between groups is shown by: **P < 0.01, ***P < 0.001 as compared to control group and, ### P < 0.001 as compared to MIA group.
