Project description:To understand the underlying cause for reduced lung metastasis, we compared global gene expression profiles of F4/80+ FACS sorted tumor-associated macrophages (TAMs) PyMT;E2f3 f/f (control) and PyMT;Lys Cre:E2f3 f/f (experimental) mice. We compared gene expression profile between TAMs isolated from mammary tumors of PyMT;E2f3 f/f and PyMT;Lys Cre:E2f3 f/f mice
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.
Project description:30 µg proteins per sample were reduced (20 mM DTT Sigma, room temperature RT, 1 h) and S-alkylated (50 mM IAA Sigma, 1 h, dark). The remaining IAA was quenched with 20 mM DTT for 1 h in the dark. The proteins were digested with 1:50(w/w enzyme:protein) MS-grade trypsin/lys-C mix (Thermo Scientific) for 24 h at RT. The enzyme digestion was quenched by lowering the pH with formic acid (Fisher) and the sample was desalted with ZipTip C18 (Merck-Millipore) column. Samples were resuspended in 10 µl of 0.2% formic acid prior LC-MS/MS analysis.
Project description:To better understand the impact of integrin beta3 signaling in myeloid cells on the tumor microenvironment, we compared the gene expression profiles of FACS isolated GFP+ PyMT-BO1 MFP tumor cells and also M2 TAMs (CD11b+Gr1-F4/80+CD206+) from tumor tissue of WT mice and b3ÎÎÎ mice. PyMT-BO1-GFP-Luc tumor cells (100,000) were injected into mammary fat pad (MFP) tissue from WT and b3KOM mice. PyMT-BO1-GFP-Luc cells and CD206hi tumor-associated macrophages (TAMs) were FACS-sorted from day 10 MFP tumor tissue. FACS-sorted cells directly used for RNA extraction and hybridization on Affymetrix microarrays.
