MicroRNA Profiling in Cartilage Ageing

Figure 4

Validation of microarray results using qRT-PCR in an independent cohort. (a) Relative expression of miRNAs between the young normal and old OA cartilages. qRT-PCR results show relative expression normalised to Rnu-6 gene, young samples  = 7-8, old OA samples . (b) Relative expression of miRNAs between the young normal and old normal samples in an independent cohort. Results show the young normal samples () and the old normal samples ( = 3-4). Mann–Whitney test was performed using GraphPad prism version 7.03; values are indicated. YN: young normal; OOA: old OA; ON: old normal.
