Abstract
Biological aging varies between individuals and may be influenced by health behaviors. Using data from 45,438 UK Biobank participants, we found that a higher proteomic aging score (ProtAgeGap) was linked to lower physical activity and increased risk of type 2 diabetes. The UK Biobank cohort included both men and women. In a 12-week supervised exercise study (MyoGlu) in 26 men, ProtAgeGap decreased by the equivalent of 10 months. While most of the 204 proteins in the score remained stable, some, like CLEC14A, changed with exercise and were linked to improved insulin sensitivity. Transcriptomic data from muscle and fat tissue supported these protein-level changes, highlighting pathways, such as PI3K-Akt and MAPk signaling, involved in tissue remodeling and metabolism. Our findings suggest that while proteomic aging is mostly stable, it can be modestly reversed by exercise. Specific proteins within the signature may act as sensitive indicators of metabolic adaptation, supporting the idea that proteomic aging is a modifiable marker linked to lifestyle and disease risk.
