Microgravity and space radiation exert either opposite or synergic effects on single molecular pathways

Project description:Microgravity and space radiation (SR) are two highly influential factors affecting humans in space flight. Many health problems reported by astronauts derive from endothelial dysfunction and impaired homeostasis. Here we describe the adaptive response of human, capillary endothelial cells to space. Reference samples on ground and at 1g onboard allowed discrimination between the contribution of microgravity and SR within the combined response to space. Cell softening and reduced motility occurred in space, with loss of actin stress fibers and a greater distribution of microtubules and intermediate filaments in compensation. The frequency of primary cilia also increased. DNA repair mechanisms were indeed activated. Transcriptomics highlighted the opposing effect of microgravity from SR on specific molecular pathways: radiation, unlike microgravity, stimulated pathways for endothelial activation (hypoxia, inflammation), DNA repair and apoptosis, promoting an ageing-like phenotype; microgravity, unlike SR, activated pathways for metabolism and pro-proliferation phenotype. Thus, microgravity and SR should be considered separately to tailor effective countermeasures to protect astronauts’ health.

Synergistic effects of microgravity and space radiation (Nimblegen)

Project description:Space radiations and microgravity both could cause DNA damage in cells, but the effects of microgravity on DNA damage response to space radiations are still controversial. A mRNA microarray and microRNA microarray in dauer larvae of Caenorhabditis elegans (C. elegans) that endured spaceflight environment and space radiations environment during 16.5-day Shenzhou-8 space mission were performed. The analyzation this study are further described in Gao, Y., Xu, D., Zhao, L., Zhang, M. and Sun, Y. (2015) Effects of microgravity on DNA damage response in Caenorhabditis elegans during Shenzhou-8 spaceflight. International journal of radiation biology, 91, 531-539.

Space microgravity increases expression of genes associated with proliferation and differentiation in human cardiac spheres

Project description:Previously, we reported upregulation of cardiac proliferation in cardiac progenitors derived from human induced pluripotent stem cells (hiPSC-CPCs) that were exposed to space microgravity for 3 days. The overall objective of this investigation was to understand how long-term exposure to microgravity affects the expansion and differentiation of hiPSC-CPCs. Cryopreserved cardiomyocytes derived from human-induced pluripotent stem cells (hiPSC-CMs) were exposed to space microgravity for 3 weeks in the International Space Station (ISS) and retrieved for transcriptomic profiling. RNA-seq analysis and gene ontology analysis revealed upregulation of cardiac tissue function and morphological terms while downregulating inflammation and ECM regulation terms. Upregulation of genes associated with cell cycle regulation and proliferation were notable as well. Combined with previous work, these results suggest that space microgravity improved cardiac differentiation and structure formation and potentially, proliferation.

Microgravity on the International Space Station promotes survival and proliferation of human stem cell cardiomyocytes

Project description:Efficient generation of functional cardiomyocytes from human induced pluripotent stem cells (hiPSC-CMs) is critical for their use in regenerative medicine and other applications. In this study, we evaluated the effect of space microgravity (µg) on the differentiation of hiPSC-derived cardiac progenitors compared with parallel 1g condition on the International Space Station. Cryopreserved 3D cardiac progenitors derived from hiPSCs were cultured for 3 weeks. Compared with 1g culture, the µg culture had larger sphere sizes, increased expression of proliferation markers, higher counts of nuclei, and higher cell viability. Highly enriched cardiomyocytes generated in µg had appropriate gene expression and cardiac structure as well as improved function including contractility and Ca2+ handling. RNA-seq analysis of 3-day cultures revealed that short-term exposure of cardiac progenitor spheres to space microgravity upregulated genes involved in cell proliferation, cardiac differentiation, and contraction. These results indicate that space microgravity increased survival and proliferation of hiPSC-CMs and improved their structures and functions.

Transcription profiling of Drosophila after exposure to microgravity in the International Space Station and in a microgravity simulator

Project description:Larvae-Pupae transition flies (Drosophila) were recovered and transport for 3 days at 12-14ºC to arrest development until the launch site, then exposed to RT (18-20ºC) for some hours including the launch and trip to the International Space Station, then pupae were exposed to microgravity in the ISS for 4 days and a half at 22ºC. Finally pupae were fixed on acetone and frozen until recovery on Earth.<br><br><br><br>Four groups of samples: 1 ISS (+ground control) as described, 2 RPM (microgravity simulator on Earth) as described, 3 RPM without constrains (No MAMBA container and only 5 days exposure without cold transport) and 4 centrifuge 10g without constrains control..
