Figure 3From: Regulation of the IGFBP-5 and MMP-13 genes by the microRNAs miR-140 and miR-27a in human osteoarthritic chondrocytes Effect of pre- and anti-miR-140 and miR-27a on MMP-13 gene expression. OA chondrocytes (n = 8) were transfected with the pre-miR (A) and anti-miR (B) molecules and incubated for 24, 48 and 72 hours. Total RNA was extracted and processed for real-time PCR/TaqMan. Levels from untreated chondrocytes (-) were assigned an arbitrary value of 1.Back to article page
