Skeletal muscle transcriptome changes after a hypertrophic stimulus, highlighting age-related shifts in isoform usage and regulatory complexity you’ll want to examine.

Key Takeaways
- A hypertrophic mechanical stimulus triggered widespread alternative isoform usage in skeletal muscle across age groups.
- Some isoform switching occurred without corresponding differential gene expression, indicating post-transcriptional regulation.
- Age influenced the pattern and magnitude of isoform changes, producing distinct transcriptomic responses in young versus old muscle.
