Immunization Induces Inflammation in the Mouse Heart during Spaceflight

ABSTRACT: Space travel is a growing area of interest and includes initiatives such as NASA's Moon-to-Mars Mission. Studies conducted on the cardiovascular effects of space travel reveal changes in morphology, metabolism, and function. In this study, the cardiovascular response to immunization in space was studied in mice which were housed and immunized while on the International Space Station (ISS). Mice were immunized with tetanus toxoid combined with the adjuvant CpG (TT+CpG) and the effects of vaccination in space were studied using transcriptomics. Analysis of the murine heart transcriptome was performed on ground, flight-control, and flight-immunized mice. Results showed that immunization aboard the ISS stimulates heightened inflammation in the heart via induction of the NF-κB signaling pathway.

Expression profiles in multiple tissues of WT and Nrf2-knockout mouse under space filght

Project description:To elucidate roles that Nrf2 plays in regulating adaptive responses to the space stress, one month-long space travel and RNA-seq analysis of six Nrf2-KO mice and six wild-type mice were conducted . After 31-days-stay in the ISS, all the flight mice returned safely to Earth. We found that Nrf2 was indeed activated by the space stress in various tissues. The space stress and Nrf2-deficiency brought about changes in gene expression.

BASE-A space experiment with Rhodospirillum rubrum S1H

Project description:R. rubrum S1H inoculated on solid minimal media was sent to the ISS in September 2006 (BASE-A experiment). After 10 days flight, R. rubrum cultures returned back to Earth. These cultures were then subjected to both transcriptomic and proteomic analysis and compared with the corresponding ground control. Whole-genome oligonucleotide microarray and high throughput proteomics, which offer the possibility to survey respectively the global transcriptional and translational response of an organism, were used to test the effect of space flight. Moreover, in an effort to identify a specific stress response of R. rubrum to space flight, ground simulation of space ionizing radiation and space gravity were performed under identical culture setup and growth conditions encountered during the actual space journey. This study is unique in combining the results from an actual space experiment with the corresponding space ionizing radiation and modeled microgravity ground simulations, which lead to a more solid dissection of the different factors contribution acting in space flight conditions. Total RNA was extracted from R. rubrum S1H grown after 10 days in space flight or after 10 days in simulated ionizing radiation or simulated microgravity. Each microarray slide contained 3 technical repeats.

MESSAGE 2 space experiment with Rhodospirillum rubrum S1H

Project description:R. rubrum S1H inoculated on solid agar rich media was sent to the ISS in October 2003 (MESSAGE-part 2 experiment). After 10 days flight, R. rubrum cultures returned back to Earth. These cultures were then subjected to both transcriptomic and proteomic analysis and compared with the corresponding ground control.

Transcriptomic Effects on the Mouse Heart Following 30 Days on the International Space Station

Project description:Efforts to understand the impact of spaceflight on the human body stem from the growing interest in long-term space travel. Multiple organ systems are affected by micro-gravity and radiation, including the cardiovascular system. Previous transcriptomic studies have sought to reveal the changes in gene expression after spaceflight. However, little is known about the impact of long-term spaceflight on the mouse heart in vivo. This study focused on transcriptomic changes in the hearts of female C57BL/6J mice flown on the International Space Station (ISS) for 30 days. RNA was isolated from the hearts of three flight and three comparable ground control mice and RNA sequencing was performed. Our analysis showed that 1,147 transcripts were significantly regulated after spaceflight. MAPK, PI3K-Akt and GPCR signaling pathways were predicted to be activated. Transcripts related to cytoskeleton breakdown and organization were upregulated, but no significant change in the expression of extracellular matrix (ECM) components or oxidative stress pathway associated transcripts occurred. Our results indicate an absence of cellular senescence, and a significant upregulation of transcripts associated with the cell cycle. Transcripts related to cellular maintenance and survival were most affected by spaceflight, suggesting that the cardiovascular transcriptome initiates an adaptive response to long-term spaceflight

Effects of a Closed Space Environment on Gene Expression in Hair Follicles of Astronauts in the International Space Station

Project description:In recent times, long-term stay has become a common occurrence in the International Space Station (ISS). However, adaptation to the space environment can sometimes pose physiological problems to the astronauts after their return. Therefore, it is important to develop healthcare technologies for astronauts. In this study, hair, an easy-to-obtain sample, was identified as the candidate. In order to investigate the genetic changes in human hair during space flight, the hair follicles of 10 astronauts were analyzed by DNA microarray and real time q-PCR analyses. Space environment induced gene expression of hair follicles of astronaut was measured 6 differnent times included 2 in flight on orbit. Ten independent experiments were performed on differing astronauts. and the sampling day was differed for each astronaut because of their schedules.

Effects of Spaceflight on Human Induced Pluripotent Stem Cell-Derived Cardiomyocyte Structure and Function

Project description:With extended stays aboard the International Space Station (ISS) becoming commonplace, there is a need to better understand the effects of microgravity on cardiac function. We utilized human induced pluripotent stem cell-derived cardiomyocytes (hiPSC-CMs) to study the effects of microgravity on cell-level cardiac function and gene expression. The hiPSC-CMs were cultured aboard the ISS for 5.5 weeks and their gene expression, structure, and functions were compared to ground control hiPSC-CMs. Exposure to microgravity on the ISS caused alterations in hiPSC-CM calcium handling. RNA-sequencing analysis demonstrated 2,635 genes were differentially expressed among flight, post-flight, and ground control samples, including genes involved in mitochondrial metabolism. This study represents the first use of hiPSCs to model the effects of spaceflight on human cardiomyocyte structure and function.

The development of Drosophila melanogaster during space flight

Project description:In prospective human exploration of outer space, the need to maintain a species over several generations under changed gravity conditions may arise. This paper reports the analysis of the third generation of fruit fly Drosophila melanogaster obtained during the 44.5-day space flight (Foton-M4 satellite, 2014, Russia), followed by the fourth generation on Earth and the fifth generation under conditions of a 12-day space flight (2014, in the Russian Segment of the ISS). The obtained results show that it is possible to obtain the third-fifth generations of a complex multicellular Earth organism under changed gravity conditions (in the cycle “weightlessness – Earth – weightlessness”), which preserves fertility and normal development. However, there were a number of changes in the expression levels and content of cytoskeletal proteins that are the key components of the spindle apparatus and the contractile ring of cells.
