Spaceflight is known to impose changes on human physiology with unknown molecular etiologies. To reveal these causes, we used a multi-omics, systems biology analytical approach using biomedical profiles from fifty-nine astronauts and data from NASA’s GeneLab derived from hundreds of samples flown in space to determine transcriptomic, proteomic, metabolomic, and epigenetic responses to spaceflight.

Overall pathway analyses on the multi-omics datasets showed significant enrichment for mitochondrial processes, as well as innate immunity, chronic inflammation, cell cycle, circadian rhythm, and olfactory functions. Importantly, NASA’s Twin Study provided a platform to confirm several of our principal findings.

Evidence of altered mitochondrial function and DNA damage was also found in the urine and blood metabolic data compiled from the astronaut cohort and NASA Twin Study data, indicating mitochondrial stress as a consistent phenotype of spaceflight.

I don't think we have this one referenced already. Posting due to some cross-overs with findings reported in ME and not just for the inclusion of the phrase "two murine space missions".

 

With mouse and human astronaut subjects, including Mark and Scott Kelly who are identical twins (Mark 1 year on the ISS). This led to an excellent cohort descriptor of flight vs healthy control — which in this case is termed "ground control"

 

I might suggest that having a deep understanding of the pathophysiology of ME/CFS might be beneficial for this century's space missions (and beyond).
