Genetic dissection of the Arabidopsis spaceflight transcriptome: Are some responses dispensable for the physiological adaptation of plants to spaceflight?
Experimentation on the International Space Station has reached the stage where repeated and nuanced transcriptome studies are beginning to illuminate the structural and metabolic differences between plants grown in space compared to plants on the Earth. Genes that are important in establishing the spaceflight responses are being identified, their roles in spaceflight physiological adaptation ar...
متن کاملAdaptation of the Skeletal System during Long-duration Spaceflight Running Title: Skeletal Adaptation in Space
This review will highlight evidence from crew members flown on space missions >90 days to suggest that the adaptations of the skeletal system to mechanical unloading may predispose crew members to an accelerated onset of osteoporosis after return to Earth. By definition, osteoporosis is a skeletal disorder − characterized by low bone mineral density and structural deterioration − that reduces t...
متن کاملOxidant damage during and after spaceflight.
The objectives of this study were to assess oxidant damage during and after spaceflight and to compare the results against bed rest with 6 degrees head-down tilt. We measured the urinary excretion of the F(2) isoprostane, 8-iso-prostaglandin (PG) F(2alpha), and 8-oxo-7,8-dihydro-2 deoxyguanosine (8-OH DG) before, during, and after long-duration spaceflight (4-9 mo) on the Russian space station ...
متن کاملOsteoclast gene expression and resorption during spaceflight
During space exploration astronauts are exposed to the microgravity environment, which has an immediate impact on many biological systems. Osteoporosis-like bone mass loss is one of the most significant effects of microgravity, with reduction ranging around at least 1-2% per month in flight. An uncoupling of bone remodeling could be responsible for this process. Data obtained from astronauts sh...
