What was done
This narrative review synthesizes research on the pathophysiological adaptation of astronauts during space missions, particularly aboard the International Space Station, focusing on biomarker alterations, organelle biology, and metabolic disruptions that mirror accelerated aging.
What was found
The abstract reports no quantitative values or statistical metrics. It describes space-induced multi-system homeostatic dysregulation, altered concentrations and expressions of biochemical and hormonal biomarkers, and changes in cellular organelles and metabolic pathways.
Why it matters
Biochemical and cellular adaptations observed under space stress may help generate new pathophysiological hypotheses, biomarker-based risk scores, and therapeutic targets for aging and metabolic disorders on Earth.
Limits
The paper is a narrative review presenting no primary experimental data or quantitative synthesis in the abstract. Astronaut sample sizes in underlying research are inherently small and highly selected, limiting generalizability to broader clinical populations on Earth.
