Gene expression analysis of 7d-old Arabidopsis seedlings exposed to short term (2 h) hypoxia, long term (9 h) hypoxia, and 1 h reoxygenation after long term (9 h) hypoxia to evaluate the regulation of gene expression at the level of translation.
Selective mRNA translation coordinates energetic and metabolic adjustments to cellular oxygen deprivation and reoxygenation in Arabidopsis thaliana.

View SamplesMPK6 shows transient increase in activity under hypoxia with maximal activity at 2 hrs. To study the role of MPK6 in hypoxia in Arabidopsis, 10 do seedlings of WT, mpk6 and MPK6 plants were exposed to 2 hrs hypoxia and 2hr air (mock).
Transient MPK6 activation in response to oxygen deprivation and reoxygenation is mediated by mitochondria and aids seedling survival in Arabidopsis.

The number and type of genes that become differentially expressed in response to infection can result in very different pathophysiologic presentations and disease course. Wild type YFV and 17D despite having very few genetic differences result in very different disease outcomes in human and monkey hosts.

View SamplesThe hemera (hmr) mutant was identified as the first photomorphogenetic mutant with the combination of long hypocotyl and albino phenotypes in the light. Phytochrome-Interacting bHLH transcription Factors (PIFs), which are repressors of photomorphogenesis accumulate in darkness and are degraded in the light in a phytochrome-dependent manner. Two PIFs, PIF1 and PIF3 accumulated in the light in hmr mutants. In order to determine the gene expression of PIF-dependent genes in hmr mutants in the light, we have performed whole-genome expression analysis on two hmr mutants: a null allele, hmr-5; and a weak allele, hmr-22.

View SamplesHNF4a is an important liver transcription factor that regulates at least a thousand genes in the liver. Here we used expression profiling in HepG2 cells, a hepatocellular carcinoma cell line, in which HNF4a was knocked down by RNAi to identify some of those target genes. This dataset accompanies the article in Hepatology 2010 Feb;51(2):642-53.

View SamplesThis dataset contains microarray data from normal controls (aged 20-99 yrs) and Alzheimer's disease cases, from 4 brain regions: hippocampus, entorhinal cortex, superior frontal cortex, post-central gyrus. Changes in expression of synaptic and immune related genes were analyzed, investigating age-related changes and AD-related changes, and region-specific patterns of change.
Gene expression changes in the course of normal brain aging are sexually dimorphic.

View SamplesPediatric adamantinomatous craniopharyngioma (ACP) cyst may be associated with injury to critical neurological structures, such as the hypothalamus, resulting in poor quality of life and shorter lifespan. This work presents evidence that immune actors, both pro-inflammatory and immunomodulatory, and their receptors, are present at unique levels in ACP cyst fluid and tumor tissue, potentially indicating a mechanism underlying cyst growth and tumor invasion of the hypothalamus.

View SamplesInflammatory response has been identified as a molecular signature of high-risk Group A ependymoma (EPN). To better understand the biology of this phenotype and aid therapeutic development, transcriptomic data from Group A and B EPN patient tumor samples, and additional malignant and normal brain data, were analyzed to identify the mechanism underlying EPN group A inflammation.
