Myogenin mRNA expression. Samples were taken from rat immediately after ECC treatment muscles at times indicated. a ECC, b ECC/+l-NAME, cont contralateral (left) no-ECC/−l-NAME muscle. Values represent mean ± SEM for five animals at each time point, expressed as relative expression levels normalized by dividing by the GAPDH level. * Significantly different from 0 day. ⁺ Significantly different from ECC/+l-NAME
