Project description:We analyzed the transcriptome of steady-state bone marrow monocytes from mice deficient for AhR in monocytes (Ccr2*AhR KO) or WT littermates.
Project description:To identify aryl hydrocarbon receptor (AHR) dependent transcriptional changes in mouse colon stem cells, we performed RNA sequencing of colon organoids from wildtype and AhR deficient mice stimulated with an high affinity AHR ligand, 5nM FICZ for 4 hours.
Project description:The AhR is a ligand activated transcription factor that may be important in normal skin physiology. We compared gene expression profiles between AhR Wt and AhR KO primary mouse keratinocyte cultures. We identified 391 genes that were differentially expressed with a 1.5 fold cutoff and p<.05, and identified the AhR as an important regulator of genes involved in normal epidermal differentiation. AhR Wt primary keratinocyte cultures (n=4) were compared with AhR KO primary keratinocyte cultures (n=3)
Project description:Immune cells can rapidly adapt their functional program in response to cytokines. How cytokine-induced transcriptional responses are affected by micro-environmental cues remains poorly understood. The Aryl hydrocarbon receptor (AhR) is a ligand-activated transcription factor sensing environmental signals including metabolites. Here we addressed the cross-talk between Interleukin-4 and AhR signaling in monocytes.
Project description:We used scRNAseq to identify potential effector cells contributing to the exacerbated inflammatory responses in AhR deficient 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.
