Identifying radiation exposure biomarkers from mouse blood transcriptome
Here we present a whole-genome survey of the murine transcriptomic response to physiologically-relevant radiation doses 2 and 8 Gy. There are 18 distinct biological samples... -
Genechip analysis of bone marrow osteoprogenitors exposed to microgravity
In March 2006 murine Bone Marrow Stromal Cells (BMSC) were flown in the Soyuz 12S to the International Space Station to investigate the effects of microgravity on their... -
Low dose ionizing radiation treated lymphoblastoid cells
Irradiated cell lines exposed to 1-10 Gy 2 Lymphoblastoid cell lines (GM15510 and GM15036) irradiated 1 2.5 5 7.5 10 Gy RNA is isolated and labeled using a T7 amplification... -
Effect of simulated microgravity on E. coli K12 MG1655 growth and gene expression
This study demonstrates simulated microgravity effects on E. coli K 12 MG1655 when grown on LB medium supplemented with glycerol. The results imply that E. coli readily... -
Expression Data from International C.elegans Experiment 1st
The effect of microgravity on gene expression in C.elegans was comprehensively analysed by DNA microarray. This is the first DNA microarray analysis for C.elegans grown under... -
Expression data from SPHINX (SPaceflight of Huvec: an INtegrated eXperiment)
Changes in the physical environment modulate cell responses and may lead to the impairment or even failure of tissue function as a result of mechanotransduction processes. It... -
Gene responses in mouse brain to long-term exposure to microgravity
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... -
Radiation responses in peripheral white blood cells of smokers and non-smokers
Understanding the possible impact of potential confounding factors is necessary for any approach to radiation biodosimetry. Potential confounding factors have not been fully... -
Bystander response to 2.5 Gy of protons in a human 3-dimensional skin model...
Bystander mechanisms that originate in the areas surrounding a tissue damage presumably play an important role participating in wound healing and tissue remodeling. Thus... -
Non-targeted effects of low dose ionizing radiation act via TGF-beta to...
This is a genome-wide approach to identifying genes persistently induced in the mouse mammary gland by acute whole body low dose ionizing radiation (10cGy) 1 and 4 weeks after... -
Bacillus subtilis spores PROTECT experiment Space-exposed and Mars-exposed...
Because of their ubiquity and resistance to spacecraft decontamination bacterial spores are considered likely potential forward contaminants on robotic missions to Mars. Thus it... -
T Cell Activation in Microgravity Compared to 1g (Earth s) Gravity
This study tested the hypothesis that transcription of immediate early genes is inhibited in T cells activated in microgravity (mg). Immunosuppression during spaceflight is a... -
An environment with strong gravitational and magnetic field alterations...
Using diamagnetic levitation we have exposed A. thaliana in vitro callus cultures to five environments with different levels of effective gravity (from levitation i.e. simulated... -
Response of Pseudomonas aeruginosa PAO1 to low shear modeled microgravity
Anticipating the risk for infectious disease during space exploration and habitation is a critical factor to ensure safety health and performance of the crewmembers. As a... -
Effect of microgravity on brain gene expression in mice
Changes in gravitational force such as that experienced by astronauts during space flight induce a redistribution of fluids from the caudad to the cephalad portion of the body... -
Transcription profiling of human peripheral blood to development gene...
To further development of our gene expression approach to biodosimetry we have employed whole genome microarray expression profiling as a discovery platform to identify genes... -
Microarray Profile of Gene Expression during Osteoclast Differentiation in...
Microgravity leads to a 10-15% loss of bone mass in astronauts during space flight. Osteoclast is the multinucleated bone resorbing cell. In this study we used NASA developed...
