... of these mechanisms can be difficult to separate. In this study, we used the western fence lizard, Sceloporus occidentalis , as an ectothermic model to determine whether a reduction in metabolic rate is sufficient to resist muscle atrophy. We induced atrophy through sciatic denervation of the gastrocnemius muscle...
