Long non-coding RNAs Kcnq1ot1 and Lncpint are involved in skeletal muscle atrophy induced by the space exposome

ABSTRACT: Long non-coding RNAs (lncRNAs) play an important role in the regulation of skeletal muscle transcriptional processes, but their involvement in spaceflight- or inactivity-induced muscle atrophy remains poorly understood. To address this gap, we simulated the space environment by combining microgravity, irradiation and stress in a mouse model. Our results provide novel insights into the contribution of lncRNAs to muscle atrophy caused by the space exposome and has broader implications for understanding and combating muscle atrophy in clinical scenarios of prolonged inactivity.

Expression profiling of soleus muscle under the effect of simulated spaceflight

Project description:Spaceflight imposes the risk of skeletal muscle atrophy for astronauts. The understanding of muscle atrophy because of spaceflight is limited, but continued efforts are essential for developing countermeasures of this effect. A distinct difference between spaceflight-induced muscle atrophy and other forms of atrophy is the additional effect of cosmic rays in outer space. To study spaceflight-induced muscle atrophy, we performed two ground-based models of microgravity in a low dose radiation environment and studied transcriptional changes in rat soleus muscle using microarray technology.

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.

Mouse muscle LC-MSMS upon weightlessness

Project description:Upon weightlessness and microgravity, deleterious effects on the neurosensory and neurovestibular systems, haematological changes, and deconditioning of musculoskeletal, cardiovascular and cardiopulmonary functions have been reported. In particular, loss of muscle mass and strength are triggered by weightlessness in humans during space flights, what is similarly observed as a result of physical inactivity conditions and ageing on Earth. However, skeletal muscle tissue is of paramount importance for health maintenance (e.g. being essential to locomotion, heat production, and metabolism). To better prevent or eventually treat microgravity-induced muscle atrophy, its underlying mechanisms have first to be characterized in details. Using cutting-edge quantitative proteomics, the aim of the present study was therefore to get an in depth view of the molecular regulations triggered by space conditions in skeletal muscles of mice during the 30-day flight of the BION-M1 biosatellite. As muscles differing in their fiber type composition appear to respond differently to microgravity (see above), we characterized here the differential response of the soleus, extensor digitorum longus and vastus lateralis muscles.

Microarray Analysis of Space-flown Murine Thymus Tissue

Project description:Microarray Analysis of Space-flown Murine Thymus Tissue Reveals Changes in Gene Expression Regulating Stress and Glucocorticoid Receptors. We used microarrays to detail the gene expression of space-flown thymic tissue and identified distinct classes of up-regulated genes during this process. We report here microarray gene expression analysis in young adult C57BL/6NTac mice at 8 weeks of age after exposure to spaceflight aboard the space shuttle (STS-118) for a period of 13 days. Upon conclusion of the mission, thymus lobes were extracted from space flown mice (FLT) as well as age- and sex-matched ground control mice similarly housed in animal enclosure modules (AEM). mRNA was extracted and an automated array analysis for gene expression was performed. Examination of the microarray data revealed 970 individual probes that had a 1.5 fold or greater change. When these data were averaged (n=4), we identified 12 genes that were significantly up- or down-regulated by at least 1.5 fold after spaceflight (p≤0.05). Together, these data demonstrate that spaceflight induces significant changes in the thymic mRNA expression of genes that regulate stress, glucocorticoid receptor metabolism, and T cell signaling activity. These data explain, in part, the reported systemic compromise of the immune system after exposure to the microgravity of space.

SCD – Stem Cell Differentiation on board the International Space Station [RNA-seq]

Project description:The bone loss observed in astronauts and animal models after spaceflight is attributable to alterations in the bone tissue formation that depends from the continuous remodeling through the activities of bone-resorbing osteoclasts of hematopoietic lineage and bone-forming osteoblasts of mesenchymal origin. This disease is frequent in aged people, but develops much more rapidly in space. Our experiment, selected by ESA (European Space Agency), aimed to determine how human bone marrow mesenchymal stem cells (hBMSCs) react and differentiate in real microgravity, on board the International Space Station, in approx. 2 weeks time.

A Molecular Genetic Basis Explaining Altered Bacterial Behavior in Space

Project description:Bacterial behavior has been observed to change during spaceflight. Higher final cell counts, enhanced biofilm formation, increased virulence, and reduced susceptibility to antibiotics have been reported to occur for cells cultured in space . Most of these phenomena are theorized as being an indirect effect of an altered extracellular environment, where the carbon source uptake is inhibited and excreted acidic byproducts buildup around the cell due to the lack of gravity-driven transport forces. However, to date neither spaceflight results, ground-based studies, physical measurement techniques nor computational approaches have provided sufficient evidence needed to confirm this model. Gene expression data from the Antibiotic Effectiveness in Space (AES-1) experiment, however, have now allowed us to look into the biomolecular processes behind these observations and showed a systematic activation of glucose starvation and acid resistance genes. These results corroborate the reduced mass transport model proposed to govern bacterial responses to spaceflight. Furthermore, the gene expression data suggests that metabolism was stimulated in space, which could play a role in causing the observed increase in bacterial cell concentrations in microgravity. Similarly, the decrease in extracellular pH may also be involved with the reported increase in virulence in space.

Skeletal Muscle-On-A-Chip in Microgravity for Sarcopenia Modeling and Advanced Drug Screening

Project description:Microgravity has been shown to lead to both muscle atrophy and impaired muscle regeneration. The purpose was to study the efficacy of microgravity to model impaired muscle regeneration in an engineered muscle platform and then to demonstrate the feasibility of performing drug screening in this model. Engineered human muscle was launched to the International Space Station National Laboratories, where the effect of microgravity exposure for 7 days was examined by transcriptomics.
