We investigated the molecular mechanisms of exercise adaptations in human muscle by integrating genome, methylome, transcriptome, and proteome data from over 1,000 participants (2,340 muscle samples). We identified distinctive signatures associated with maximal oxygen consumption (VO2max), and multi-omics integration uncovered five key genes as robust exercise markers across layers, with transcription factors functioning as activators, synergizing with DNA methylation to regulate gene expression. Minimal sex differences were observed, while modality-specific analysis highlighted distinct pathways for aerobic and resistance exercise, contrasting with muscle disuse patterns. Finally, we created a webtool, OMAx, featuring our individual omics and integration analysis. These findings provide …

Introduction Breast cancer is the most commonly diagnosed cancer among women worldwide. Survivors often experience physical and psychological effects arising from breast cancer and its treatment, which can last months and years, adversely impacting quality of life. As the number of early breast cancer survivors increases, models of specialist-led follow-up care in hospital settings are not sustainable and evidence suggests that they may not meet survivors’ needs. Nurse-enabled, shared-care, follow-up models between cancer specialist and primary care teams have potential to address this need. Methods and analysis The proposed research is a multicentre, prospective, pragmatic, stepped-wedge cluster-randomised trial designed to …
