Characterization of RORα MKO mice. (A) mRNA expression levels measured by RT-qPCR for Lyz2 and Cre genes in spleen from WT (Rora+/+
Lyz2Cre/+) and MKO (Rorafl/fl
Lyz2Cre/+) mice. (B) PCR analysis of genomic DNA extracted from sorted splenic macrophages of WT and MKO mice. Locations of primer hybridization are represented with filled diamond. Agarose gels were acquired with a Gel Doc XR system (Bio-Rad) and the Image Lab software verion 2.0 build 8 for PC (Bio-Rad, https://www.bio-rad.com/fr-fr/product/image-lab-software?ID=KRE6P5E8Z). Images were cropped for sake of clarity and full-length gels are presented in Supplementary Fig. 6. (C) mRNA expression levels measured by RT-qPCR for the exon 3 of Rora in B cells, T cells, neutrophils, macrophages, monocytes, and dendritic cells (DCs) sorted from the spleen of WT and MKO mice. (D) mRNA expression levels measured by RT-qPCR for the exon 3 of Rora in total bone marrow (BM) cells, in neutrophils purified from BM and in BM-derived macrophages (BMDM) from WT and MKO mice. (E,F) mRNA expression levels measured by RT-qPCR for Rorc (D) and Arntl (E) genes in B cells, T cells, neutrophils, macrophages, monocytes, and DCs sorted from the spleen of WT and MKO mice. (G) mRNA expression levels measured by RT-qPCR for Arntl in BMDM. (H) mRNA expression levels measured by RT-qPCR for the exon 3 of Rora, Arntl, Rorc and Adgre1 in adipose tissue macrophages (ATM) sorted from epididymal adipose tissue of WT and MKO mice. (I) mRNA expression levels measured by RT-qPCR for the exon 3 of Rora in liver, epididymal adipose tissue (epiAT) and skeletal muscle from WT and MKO mice. Data are shown as mean ± SEM. * p < 0.05; ** p < 0.01; *** p < 0.001 by 2-way ANOVA followed by Sidak’s multiple comparisons test or unpaired t test. All statistical analyses were carried out using GraphPad Prism 8 for Windows (GraphPad Software). n = 8–10 mice per genotype for A & I. n = 5 mice per genotype for C,E & F. n = 3 mice per genotype for D & G. For H, each dot represents a pool of 3–4 mice. NS: Not significant; AU: Arbitrary unit; FC: Fold change. See also Fig. S1.
