Affymetrix Mouse Clariom S Array (clariomsmouse)
Description
To assess the role of the aryl hydrocarbon receptor (AHR) receptor in dendritic epidermal T cells (DETC), we sorted DETC from 2 weeks old mice homozygous and heterozygous for AHR-knockout. While DETC are not maintained in the epidermis of mice with a homozygous AHR-knockout, those in heterozygous mice devellop normally. The age at 2 weeks is critical for the DETC establishment and the peak time of the so-called proliferation burst of DETC in wildtype mice. DETC were identified in epidermal cell suspension by expression of the gamma-delta T cell receptor. The DETC proportion of live epidermal cells was between 10-15 % in Ahr-het and 2-4 % in Ahr-ko mice. After FACS-sorting to a purity of 90-98 %, DETC were lysed and their RNA was extracted. Three RNA samples for each genotype were generated, by pooling the RNA of 2-3 mice for each sample. RNA was processed and hybridized to Applied BiosystemsTM ClariomTM S Mouse Gene Expression Microarrays. Using the Software package R the data were normalized using the Robust Multichip Average algorithm (RMA) and significance of differentially regulated genes was assessed by the False Discovery Rate (FDR) using the Benjamini and Hochberg’s method.

- Affymetrix Mouse Gene 2.0 ST Array (mogene20st)
Description
Microarrays were used to identify the differentially expressed genes in the hippocampus of control and Noonan syndrom mice at basal state and in response to 4AP-Bic stimulation (10 min). Functional analysis was performed to determine the biological significance of the data.

- Affymetrix Mouse Genome 430A 2.0 Array (mouse430a2)
Description
Over activation of the aryl hydrocarbon receptor (AhR) by TCDD results ampng other phenotypes in severe thymic atrophy accompanied by immunosuppression. The link between thymic atrophy, skewed thymocyte differntiation and immunosuppression is still not fully resolved. This study investigates the TCDD elicted exprssion changes in the ET, cortical thymus epithelial cell line.
Publication Title
Promoter analysis of TCDD-inducible genes in a thymic epithelial cell line indicates the potential for cell-specific transcription factor crosstalk in the AhR response.

- Affymetrix Mouse Expression 430A Array (moe430a)
Description
Over-activation of the aryl hydrocarbon receptor by TCDD in mice leads among other phenotypes to a severe thymic atrophy accompanied by immunosuppression. TCDD causes a block in thymocyte maturation and a preferential emigration of immature CD4-CD8- DN thymocytes (recent thymic emigrants) into the periphery. As part of this study gene expression profiles from DN thymocytes and thymic emigrants were generated from TCDD and solvent control mice
