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... -
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... -
Salmonella Typhimurium transcription profiles in space flight
Salmonella transcription profiles were obtained from samples flown on space shuttle mission STS-115 and compared to profiles from Salmonella grown under identical conditions on... -
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... -
Gene expression profiling of C. elegans under various thermal conditions
To realistically evaluate the effects of the environment in space it is necessary to understand the effects of external factors during sample transport from Earth to space. The... -
Global Identification of Noncoding RNAs in S. cerevisiae
Genome-wide detection of novel non-coding RNAs in S. cerevisiae by modulating an RNase P pathway through the depletion of a component RPP1. Nearly 400,000 36-mer oligonucleotide... -
Transcription profiling of rat to study the effect of hindlimb unloading on...
A recent physiological study established that hindlimb unloading of rats at 3 and 7 weeks inhibits healing of injured ligaments resulting in a badly aligned discontinuous... -
Human skin fibroblast mitochondrial depletion 0.5 Gy alpha-particle
Mitochondrial DNA-depleted human skin fibroblasts (HSF rho0) with suppressed oxidative phosphorylation were characterized by significant changes in the expression of 2100... -
IMR90 4hr bystander experiment 0.5Gy alpha particle strip dish format
Radiation affects tissue and cellular integrity at the level of DNA protein and metabolites of the cell and extracellular space. The effects of radiation are not limited to... -
Transcription profiling of Drosophila exposed to a levitation magnet for...
Drosophila samples were exposed to the levitation magnet inside a 25mm diameter tubes with 3 ml of yeast-based Drosophila food in the bottom and a chamber of only 5 mm of height... -
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... -

Comparison of gene expression profiles of normal human bronchial epithelial...
The experiment is part of a project to study DNA repair process after ionizing radiation in organotypic 3-dimentional human bronchial epithlial cell culture. Human bronchial... -
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... -
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... -
Transcription profiling of Drosophila after exposure to microgravity in the...
Larvae-Pupae transition flies (Drosophila) were recovered and transport for 3 days at 12-14C to arrest development until the launch site then exposed to RT (18-20C) for some... -
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...
