P-GSE41910-2 - P-GSE41910-2
Male mice were used from an animal model of selectively bred for high voluntary wheel-running behaviour (HR) and lines bred without intentional selection. Animals used in the current work were sampled from generation 37 at a mean age of 84 days (range = 79-86). We used gastrocnemius muscles (including both lateral and medial portions) from the mice described above for HRmini line #3 and HRnormal line #8 (n = 6, in each group). To obtain sufficient RNA, gastrocnemius samples of HRmini were pooled from left and right limbs from each animal, whereas HRnormal gastrocnemius was sampled from either left or right limb only.
