Effect of aryl hydrocarbon receptor (Ahr) gene knockout on expression profiles of murine hematopoietic stem cells

Project description:As part of a study of the role of the aryl hydrocarbon receptor (Ahr) in maintenance and senescence of hematopoietic stem cells (HSC), global gene expression profiling was done with HSC isolated from Ahr-knockout and wild-type mice. HSC from young-adult (8 wk old) AhR-KO mice had changes in expression of many genes related to HSC maintenance, consistent with the phenotype observed in aging Ahr-KO mice: decreased survival rate, splenomegaly, increased circulating white blood cells, hematopoietic cell accumulation in tissues, anemia, increased numbers of stem/progenitor and lineage-committed cells in bone marrow, decreased erythroid progenitor cells in bone marrow, and decreased self-renewal capacity of HSC. 7 samples: 3 Ahr knockout, 4 wild-type

Microarray analysis of CA-AhR transgenic mice

Project description:We have generated transgenic mice expressing constitutively activated aryl hydrocarbon receptor (CA-AhR) to examine the biological consequences of AhR activation.. We used microarrays to identify genes that are regulated by AhR. Livers or intestines from three female mice were pooled at 5-6 week-old for RNA extraction and hybridization on Affymetrix Mouse Genome 430 2.0 Array.

Proteome and Phosphoproteome of AhR-dependent non-genomic signaling in endotoxin-activated macrophages

Project description:Emerging studies revealed an immunomodulatory role of the Aryl hydrocarbon receptor (AhR), a receptor sensing environmental contaminants, and involved in their detoxification. Besides its function as a transcription factor, AhR can participate in non-genomic signaling through ubiquitination and phosphorylation-dependent processes. In this study, a multi-PTM-omics approach, including proteome, ubiquitome, and phosphoproteome, was utilized to examine mechanisms of non-genomic AhR-signaling in endotoxin-activated monocyte-derived macrophages. This dataset entails proteome and phosphoproteome data.

AhR interactome in early embryonic development

Project description:The transcriptional program of early embryonic development is tightly regulated by a set of well-defined transcription factors that suppress premature expression of differentiation genes and sustain the pluripotent identity. It is generally accepted that this program can be perturbed by environmental factors such as chemical pollutants, however the precise molecular mechanisms remain unknown. The Aryl Hydrocarbon Receptor (AHR) is a widely expressed nuclear receptor that senses environmental stimuli and modulates target gene expression. Here, we show that ectopic activation of AHR during early differentiation disrupts the differentiation program via the chromatin remodeling complex NuRD. The activated AHR/NuRD complex altered the expression of differentiation-specific genes that control the first two developmental decisions without affecting the pluripotency program. These findings identify a novel mechanism that allows environmental stimuli to disrupt embryonic development through AHR signaling.

Aryl hydrocarbon receptor (AHR)-dependent protection against lung vascular leakage in viral infection

Project description:Disruption of the lung endothelial-epithelial cell barrier during respiratory virus infection causes cell and fluid accumulation in the air spaces and compromises vital gas exchange function. Endothelial cell dysfunction is known to exacerbate tissue damage; however, it is unclear whether the lung endothelium engages in tissue-protective activity during viral infection. Here we show that the environmental sensor aryl hydrocarbon receptor (AHR) is predominantly active in endothelial cells and protects against influenza-induced lung damage. Endothelial-specific AHR deletion caused increased vascular leakage in air spaces and enhanced influenza-induced lung tissue pathology. Global expression profiling revealed limited AHR-dependent regulation of vessels in the steady-state lung. However, following influenza-induced tissue damage and inflammation, AHR engages tissue-protective programmes in endothelia and prevents a dysplastic keratinised and apoptotic signature in the airways of infected lungs.
