Project description:We previously reported that a synthetic Nod1 ligand, FK565, induced coronary arteritis in mice similar to Kawasaki disease. However, the molecular mechanisms underlying this site-specific inflammation have remained elusive. In this study, we found that CD11c+MHC class II+ cells accumulated in the heart of FK565-treated mice prior to arteritis development. We used microarray analysis to detail gene expression of CD11c+MHC class II+ cells. To obtain gene expression profile of CD11c+MHC class II+ cells, we isolated these cells from hearts of FK565-treated mice. Briefly, female mice at 8weeks age were administered 500 μg of FK565 subcutaneously at day 0 and day 3. At day6, murine hearts were removed and digested with collagenase. CD11c+MHC II+ cells were sorted as PI–CD45+Ly6G–NK1.1–CD11b+CD11c+MHC II+ using FACS Aria cell sorter (BD Biosciences). Sorted cells were subjected to RNA preparation. Two independent replicates from ten mice were made.

Project description:To investigate the functional properties of Ly6G+ DC, we employed GeneChip analysis to compare the gene expression profiles between Ly6G+ DC and Ly6C- DC. Crude bone marrow (BM) cells prepared from C57BL/6 mice were cultured in the presence of GM-CSF. On day 6, CD11c+/MHC II+/Ly6G+ cells and CD11c+/MHC II+/Ly6G- cells were simultaneously sorted from the same cultures by FACSAria. Total RNA were extracted and hybridized on Affymetrix microarrays.
Project description:We collected whole genome testis expression data from hybrid zone mice. We integrated GWAS mapping of testis expression traits and low testis weight to gain insight into the genetic basis of hybrid male sterility.
