Staphylococcus warneri Proteomic

ABSTRACT: Many studies have shown that space environments can affect bacteria to varying degrees and cause a range of mutations. However, so far, there have been no relevant studies on the effects of long-term space flight (>1 month) on bacteria and the effects of different space residence time on bacteria. Therefore, we utilized the Staphylococcus warneri isolated from the Shenzhou-10 spacecraft that had experienced a space flight to carry into space again, in order to study the influence of the long flight formed by two space flights on the proteomic level.

Many studies have shown that the space environment can affect bacteria by causing a range of mutations. However, to date, few studies have explored the effects of long-term spaceflight (>1 month) on bacteria. In this study, a Staphylococcus warneri strain that was isolated from the Shenzhou-10 spacecraft and had experienced a spaceflight (15 days) was carried into space again. After a 64-day flight, combined phenotypic, genomic, transcriptomic, and proteomic analyses were performed to compare th ...[more]

Immunization Induces Inflammation in the Mouse Heart during Spaceflight

Project description: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.

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.

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.

Space flight mouse plasma cell-free RNA seuqnencing in Mouse Habitat Unit-1 (MHU-1)

Project description:Purpose: Sequencing analysis of plasma cell-free RNA was performed to study the effects of space flight and microgravity environment in mice. Methods: Plasma samples were collected during the JAXA MHU-1 mission as reported previously (Shiba et al., 2017, Scientific Reports). Total RNA was purified from plasma samples and processed for sequencing analysis, to compare RNA expression profiles in ground control, space flight and artificial 1-G control groups.

Evaluation of in vitro macrophage differentiation during space flight

Project description:We differentiated mouse bone marrow cells in the presence of recombinant macrophage colony stimulating (rM-CSF) factor for 14 days during the flight of space shuttle Space Transportation System (STS)-126. We tested the hypothesis that the receptor expression for M-CSF, c-Fms was reduced. We used flow cytometry to assess molecules on cells that were preserved during flight to define the differentiation state of the developing bone marrow macrophages; including CD11b, CD31, CD44, Ly6C, Ly6G, F4/80, Mac2, c-Fos as well as c-Fms. In addition, RNA was preserved during the flight and was used to perform a gene microarray. We found that there were significant differences in the number of macrophages that developed in space compared to controls maintained on Earth. We found that there were significant changes in the distribution of cells that expressed CD11b, CD31, F4/80, Mac2, Ly6C and c-Fos. However, there were no changes in c-Fms expression and no consistent pattern of advanced or retarded differentiation during space flight. We also found a pattern of transcript levels that would be consistent with a relatively normal differentiation outcome but increased proliferation by the bone marrow macrophages that were assayed after 14 days of space flight. There also was a surprising pattern of space flight influence on genes of the coagulation pathway. These data confirm that a space flight can have an impact on the in vitro development of macrophages from mouse bone marrow cells. MESH:Space Flight/Space Flight

Changes in gene expression in Neural crest boundary cap cells after space flight

Project description:Neural crest boundary cap cells were subjected to space flight and compared against controls not subjected to space conditions. The cells were not cultured in a cell incubator during space flight, so one control was the same cells kept outside incubator for the same time. One control was cells cultured during standard conditions. One control was subjected to short pulses of artificial microgravity on earth and one culture was subjected to artificial gravity in the same way as the cells in space.

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.
