Description
Endothelin-1 (ET-1), an endothelium-derived vasoconstrictor peptide, plays a role in the pathophysiology of cardiovascular disease. Transgenic mice that overexpress human preproET-1 selectively in the endothelium (eET-1) exhibit endothelial dysfunction, hypertrophic remodeling and vascular inflammation of resistance-size arteries in the absence of blood pressure elevation. To understand the mechanisms whereby ET-1 induces vascular damage, vascular gene expression using DNA microarrays was employed. RNA from mesenteric arteries of female and male young (6-7 weeks) and mature (6-8 months) eET-1 and wild type (WT) mice was isolated and changes in gene expression were determined by genome-wide expression profiling using Illumina microarray. This study revealed a set of genes potentially regulated by ET-1, which might be implicated in ET-1 induced-vascular damage.

- Affymetrix Arabidopsis ATH1 Genome Array (ath1121501)
Description
Plants exhibit a robust transcriptional response to gamma radiation which includes the induction of transcripts required for homologous recombination and the suppression of transcripts that promote cell cycle progression. Various DNA damaging agents induce different spectra of DNA damage as well as collateral damage to other cellular components and therefore are not expected to provoke identical responses by the cell.
Publication Title
High atomic weight, high-energy radiation (HZE) induces transcriptional responses shared with conventional stresses in addition to a core "DSB" response specific to clastogenic treatments.

Description
We used the ileal loop model to assess the effects of enteric bacteria organisms on host gene expression in intestinal tissue independent of and following early SIV infection. SIV infection in the gut causes rapid and severe immune dysfunction and damage to the intestinal structure, this may alter the intimate interaction with lumenal organisms. This study was performed to determine whether early SIV infection, prior to the depletion of CD4+ T cells, can alter interaction of the host with pathogenic Salmonella serovar Typhimurium (ST) or commensal Lactobacillus plantarum (LP), and to further understand the earliest changes to the intestinal mucosa following SIV infection.
Publication Title
Early mucosal sensing of SIV infection by paneth cells induces IL-1β production and initiates gut epithelial disruption.

Description
Most studies have analysed the effects of high dose radiation such as atomic bomb survivors in Japan, people exposed during the Chernobyl nuclear accident, patients undergoing radiation therapy, uranium miners, etc. However, it has been difficult to measure and assess the risk of cancer in people exposed to lower doses of ionising radiation, such as the people living at high altitudes, who are exposed to more natural background radiation from cosmic rays than people at sea level. We measured the genomic response to X-ray ionising radiation (10 cGy and 100 cGy) in a skin tissue model to compare the effects of low and high dose ionising radiation at different time points. The microarray data was then analysed using state-of-the art upside-down pyramid computational systems biology methods to identify genes contributing to the difference in the response to the different radiation doses.

Comparison of low and high dose ionising radiation using topological analysis of gene coexpression networks.

Description
PURPOSE To identify retinal pigment epithelial (RPE)/choroid genes and their relevant expression pathways affected by intravitreal injections of dexamethasone and triamcinolone acetonide in mice at clinically relevant time points for patient care. METHODS Differential gene expression of over 34,000 well-characterized mouse genes, in the RPE/choroid of 6 week old C57BL/6J mice were analyzed after intravitreal steroid injections at 1 week and 1 month post injection, using Affymetrix Mouse Genome 430 2.0 microarrays. The data were analyzed using GeneSpringGX12.5 and Ingenuity Pathway Analysis (IPA) microarray analysis software for biologically relevant changes. RESULTS Both triamcinolone and dexamethasone caused differential activation of genes involved in Circadian Rhythm Signaling pathway at both time points tested. Triamcinolone (TAA) uniquely induced significant changes in gene expression in Calcium Signaling (1 week) and Glutamate Signaling pathways (1month). In contrast, Dexamethasone (Dex) affected the GABA Receptor Signaling (1 week) and Serotonin Receptor Signaling (1month) pathways. CONCLUSIONS Understanding how intraocular steroids affect the gene expression of RPE/choroid is clinically relevant. This in vivo study has elucidated several genes and pathways that are potentially altering the circadian rhythms and several other neurotransmitter pathways in RPE/choroid cells during intravitreal steroid injections, which likely has consequences in the dysregulation of RPE function and neurodegeneration of the retina.
