Figure 4: Dysregulated mRNA, miR-146a and miR-146b expression is observed in OA articular chondrocytes compared to control chondrocytes.

Data presented as the median and interquartile range of the fold change in MMP13 mRNA (A), COL2A1 mRNA (B) and AGCAN mRNA (C), miR-146a (D) and miR-146b (E) expression in OA articular chondrocytes relative to control chondrocytes. Values are presented as individual biological replicates n = 11, *P < 0.05, **P < 0.01, ***P < 0.001, ****P < 0.0001, Mann-Whitney U test. Supplementary Figure S1. Full length images of the cropped blots presented in main Fig. 3D. Full length images in Figure S1 demonstrate that increased levels of miR-146b in human bone marrow derived SSCs reduces SOX5 expression. Human bone marrow derived SSCs were cultured in the presence of miR-146b mimic and non-targeting miRNA mimic. Human bone marrow derived SSCs were isolated from 6 individual patient samples. β-actin was used as the internal control.
