Fig 1: Levels of (a) telomere repeat factor- 1 (TRF1), (b) telomere repeat factor-2 (TRF2), (c) TRF1-interacting protein 2 (TIN2), and (d) ATM kinase in muscle samples, determined using ELISA tests. Values are the mean +/- standard deviation. Statistical differences were analyzed using the unpaired t-test. Differences of p < 0.05 were considered statistically significant, ** p < 0.01.
