* Cell-Free Mitochondrial DNA as a Potential Biomarker for Astronauts' Health.

- Background Space travel-associated stressors such as microgravity or radiation exposure have been reported in astronauts after short- and long-duration missions aboard the International Space Station. Despite risk mitigation strategies, adverse health effects remain a concern. Thus, there is a need to develop new diagnostic tools to facilitate early detection of physiological stress. Methods and Results We measured the levels of circulating cell-free mitochondrial DNA in blood plasma of 14 astronauts 10 days before launch, the day of landing, and 3 days after return. Our results revealed a significant increase of cell-free mitochondrial DNA in the plasma on the day of landing and 3 days after return with vast ~2 to 355-fold interastronaut variability. In addition, gene expression analysis of peripheral blood mononuclear cells revealed a significant increase in markers of inflammation, oxidative stress, and DNA damage. Conclusions Our study suggests that cell-free mitochondrial DNA abundance might be a biomarker of stress or immune response related to microgravity, radiation, and other environmental factors during space flight.

(9) significant, substantial -- (fairly large; "won by a substantial margin") 3. (3) significant -- (too closely correlated to be attributed to chance and therefore indicating a systematic relation; "the interaction effect is significant at the .01 level"; "no significant difference was found") 4.
