Figure 2. Validation of age-associated miRNA alterations and impact of CR.
(A-C) RT-qPCR analysis showing the abundance of the indicated miRNAs in young (Y), old (O), and old CR (OCR). RNAs from 9 Y samples, 7 O samples, and 9 OCR samples were used for this analysis and data was normalized to the average of U1 and U6 snRNA levels.
