Aging and frailty biomarkers impacted by space travel

Spaceflight has been found to accelerate aging symptoms in astronauts, manifesting through genomic instability, mitochondrial disruptions, and heightened inflammation. This research marks the first detailed analysis of biomarkers and biological pathways connected to spaceflight as well as aging, frailty, and sarcopenia on Earth.

Key Observations:

Space travel triggered significant gene expression changes associated with muscle degradation and frailty-like conditions.

The space environment exposure promoted biological shifts linked to inflammation, muscle atrophy, and other age-related characteristics in both mice and human subjects.

The parallels between the effects of space travel and natural aging could extend to include frailty.

The findings underline the importance of developing a frailty index for assessing the progression of frailty-related health risks in astronauts. These insights may also guide new strategies to mitigate frailty issues in both astronauts and the elderly population on Earth.

This research was published as part of the 44-article Space Omics and Medical Atlas (SOMA) series in Nature. It underscores how open science, with strong data submission protocols, standards, and curation, can drive significant findings. The research was initiated and managed by NASA's Open Science Data Repository (OSDR) Analysis Working Groups (AWGs).
