Project description:The spaceflight experiment was carried out using male C57BL/10J mice (8 weeks old at launch). Wild type mice (n=3) were launched by Space Shuttle Discovery and housed on the International Space Station (ISS) for 91 days. They returned to the Earth by Space Shuttle Atlantis. But only one mouse returned to the Earth alive. Whole brain was sampled from the mouse killed by inhalation of carbon dioxide at the Life Sciences Support Facility of Kennedy Space Center within 3-4 hours after landing. After the spaceflight experiment, the on-ground experiment was also carried out at the Advanced Biotechnology Center in Genova, Italy. A mouse with the same species, sex, and age was housed in mice drawer system (MDS), which was utilized for the spaceflight (SF) mice, for 3 months as the ground control (GC). Another mouse was housed in normal vivarium cage as the laboratory control (LC). Amount of food and water supplementation and environmental conditions were simulated as the flight group. After 3 months, brain was sampled from one mouse in group GC and LC, respectively. Comprehensive analyses of gene expression were performed in the right brain. Total of 4,000 genes were analyzed. The expression levels of 60 genes significantly changed in response to SF compared with LC and/or GC. The 15 and 16 genes were up- (> 2 folds) and down-regulated (< 0.5 folds), respectively, following SF vs. GC. The levels of 58 genes were significantly altered by housing in MDS in space and/or on the ground. Forty seven and 11 genes were significantly up- and down-regulated vs. LC. Twenty seven out of these genes responded to caging in MDS both in space and on the ground. Further, 31 genes were influenced by housing in MDS on the Earth. Responses of the characteristics of brain to long-term gravitational unloading were investigated in mice.

Project description:Marine Synechococcus, together with Prochlorococcus, contribute to a significant proportion of the primary production on Earth. The spatial distribution of these two groups of marine picocyanobacteria depends on different factors such as nutrients availability or temperature. Some Synechococcus ecotypes thrive in mesotrophic and moderately oligotrophic waters, where they exploit both oxidized and reduced forms of nitrogen. Here, we present a comprehensive study, which includes transcriptomic and proteomic analyses of the response of Synechococcus sp. strain WH7803 to nanomolar concentrations of nitrate, compared to ammonium or nitrogen starvation. We found that Synechococcus has a specific response to nanomolar nitrate concentration that differs to the response showed under nitrogen starvation or the presence of standard concentrations of either ammonium or nitrate. This fact suggests that the particular response to the uptake of nanomolar concentration of nitrate could be an evolutionary advantage for marine Synechococcus against Prochlorococcus in the natural field.

Project description:Colonization of land from marine environments was a major transition for biological life on Earth, and intertidal adaptation was a key evolutionary event in the transition from marine- to land-based lifestyles. Multicellular intertidal red algae exhibit the earliest, systematic, and successful adaptation to intertidal environments, with Porphyra sensu lato (Bangiales, Rhodophyta) being a typical example. We used proteomic analyse to reveal the complex regulation of rapid responses to intertidal dehydration/rehydration cycling within Neoporphyra haitanensis. These adaptations include rapid regulation of its photosynthetic system, a readily available capacity to utilize ribosomal stores, an excess of methylation supply to rapidly synthesize proteins, and a strong anti-oxidation system to dissipate excess redox energy upon exposure to air. These novel insights into the unique adaptations of red algae to intertidal lifestyles inform our understanding of adaptations to intertidal ecosystems and the unique evolutionary steps required for intertidal colonization by biological life.

Project description:Earth tilted rotation and translation around the Sun produce one of the most pervasive rhythms on our planet, giving rise to seasonal variations in diel cycles. Although marine phytoplankton plays a key role on ecosystems, multiomics analysis of its response to these periodic environmental signals remains largely unexplored. The marine picoalga Ostreococcus tauri, which resides at the base of the green lineage, has been chosen as model organism due to its high abundance in marine phytoplankton and its cellular and genomic simplicity, making it the smallest free living eukaryote. Ostreococcus was subjected to different light regimes: summer long days, winter short days, constant light and constant dark conditions, to investigate these responses. Although 80% of the transcriptome presented diel rhythmicity, less than 5% maintained oscillations under constant conditions. A drastic reduction in proteome rhythmicity was observed with 55% of the proteins oscillating. Seasonal specific rhythms were found for key physiological processes such as cell cycle, photosynthesis, carotenoid biosynthesis, starch accumulation and nitrate assimilation. In this study, a global orchestration between transcriptome, proteome and physiological dynamics was characterised identifying specific seasonal temporal offsets between peaks in transcripts, proteins, and physiological responses.

Project description:The goal of this study is to compare the transcriptome (RNA-seq) modulations in the roots and shoots of Arabidopsis thaliana, as a plant model, exposed to two toxic concentrations of rare earth elements. Lanthanum and ytterbium were used as representative of light and heavy rare earth elements, respectively.

Project description:The paired low-metastatic 95C and high-metastatic 95D cell lines were subcloned from a low differentiated human large cell lung carcinomacell line PLA-801. The cells were well authenticated and published by several research groups. The cells were kindly provided by Professor Ying-Lin Lu, Department of Pathobiology, Institute of Basic Medical Sciences, Academy of Military Medical Sciences, Beijing, China on Dec. 5，2009. As described The 95C and 95D cells were cultured in RPMI 1640 (Invitrogen, USA) with 100 units/mL penicillin, 100 μg/mL streptomycin and 10% calf bovine serum, and grown at 37° C in atmosphere with 5% CO2. miRNAs differential expression between 95C and 95D was measured using a miR human_01_H10.1_080277 miRNA array (LC Sciences Houston, USA).

Project description:Space travel presents unlimited opportunities for exploration and discovery, but requires a more complete understanding of the immunological consequences of long-term exposure to the conditions of spaceflight. To understand these consequences better and to contribute to design of effective countermeasures, we used the Drosophila model to compare innate immune responses to bacteria and fungi in flies that were either raised on earth or in outer space aboard the NASA Space Shuttle Discovery (STS-121). Microarrays were used to characterize changes in gene expression that occur in response to infection by bacteria and fungus in drosophila that were either hatched and raised in outer space (microgravity) or on earth (normal gravity). Whole Oregon R strain drosophila melanogaster fruit flies either raised on earth or in space that were (1) uninfected, (2) infected with bacteria (Escherichia coli), or (3) infected with fungus (Beauveria bassiana) were used for RNA extraction and hybridization on Affymetrix microarrays.
