Figure Lengend Snippet: Generation and validation of club cell-specific AHR knockout mice ( Ahr ΔCC). (a) Schematic of breeding strategy to generate Ahr ΔCC mice by crossing Ahr fl/fl mice with Scgb1a1-CreER TM mice, followed by tamoxifen induction. (b) Immunofluorescence staining showing club cell marker CC10 (green), AHR (red) and DAPI (blue) in lung sections of Cre-negative Ahr fl/fl LM control (top panel) and Ahr ΔCC (bottom panel) mice. (c) Representative flow cytometry plots of lung epithelial cells gated as CD45 − CD31 − EpCAM + CC10 + cells isolated from lungs of LM (left) or Ahr ΔCC (center) mice and Fluorescence-minus-one (FMO) control for AHR staining (right). (d) Quantification of the percentage of AHR + CC10 + cells in the lungs of LM (white bar) and Ahr ΔCC (gray bar) mice. Data represent mean ± SEM, n = 3-4 mice per group. Statistical significance was determined using Student's t-test; ∗p < 0.05.
Article Snippet: Male Ahr tm3.1Bra /J mice carrying a floxed exon 2 allele of the Ahr gene (JAX stock #006203) and female B6N.129S6(Cg)- Scgb1a1 tm1(cre/ERT)Blh /J mice expressing tamoxifen-inducible Cre recombinase under the control of the club cell-specific Scgb1a1 promoter (JAX stock #016225) were obtained from Jackson Laboratory.
