Project description:We used microarrays to investigate the effects of microgravity and space radiation on the genome-wide expression of the C. elegans. Three technical replicates of wild type C. elegans (CC1 strain) which exposed to space radiation are analyzed along with ground control.

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.

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.

Project description:In space, multiple unique environmental factors, particularly microgravity and space radiation, pose constant threat to the astronaut’s health. To gain insight into the role of miRNAs and lncRNAs in response to radiation and microgravity, we analyzed RNA expression profiles in human lymphoblastoid TK6 cells incubated for 24 h in static condition or in rotating condition to stimulate microgravity in space after 2 Gy γ-ray irradiation. Expression of 14 lncRNAs and 17 mRNAs was found to be significantly down-regulated in the simulated microgravity condition. In contrast, irradiation up-regulated the expression of 55 lncRNAs and 56 mRNAs, while only one lncRNA, but no mRNA, was down-regulated. Furthermore, 2 miRNAs, 70 lncRNAs, and 87 mRNAs showed significantly altered expression under simulated microgravity after irradiation, and these changes were independently induced by irradiation and simulated microgravity. Together, our results indicate that simulated microgravity and irradiation additively and independently alter the expression of RNAs and their target genes in human lymphoblastoid cells.
