Genome-wide translational analysis of the effect of acute endurance exercise on mouse gastrocnemius
Purpose: The aim of this study is to investigate the translational regulation of skeletal muscle during acute endurance exercise. Methods: We used mRNA-Seq and ribosome profiling to examine transcriptional and translational regulation, respectively. Result: There were clear distinctions between the profiles of transcription and translation even at a basal condition. TOP-motif genes were translationally suppressed immediately after the exercise. Other genes, such as Slc25a25 was significantly translationally up-regulated presumably in a mTOR-independent manner. Conclusion: There were diverse regulation between transcription and translation. Although many focused on overall protein synthesis to understand the effect of exercise, translational regulation of individual genes are required. Overall design: Transcriptional and translational profiles of mouse gastrocnemius with or without acute endurance exercise were generated using Ion PGM sequencer.
