Effect of Sirt6 deficiency on transcriptome in skeletal muscle of mice
Expanding the exercise capacity is an emerging strategy to combat metabolic diseases. Skeletal muscle fiber type determination is critical for the exercise performance, but the regulatory basis is largely unknown. Here, we report that Sirt6 has a role in regulating myofiber configuration toward oxidative type and that Sirt6 activator can be an exercise mimetic. To elucidate molecular mechanisms, we performed RNA-sequencing analysis using WT and skeletal muscle-specific Sirt6 KO mice. Transcriptomic analysis enabled us to discover major signaling nodes altered by Sirt6 deficiency in close association with mitochondrial function and muscle phenotypes. Overall design: Examination of RNA profile in gastrocnemius muscles of WT and skeletal muscle-specific Sirt6 KO mice.
