Project description:Embryonic fibroblast from C57BL/6 (B6) mice were reprogrammed to EiPS without exogenous DNA integration using an single episomal vector. The EiPS cells and B6 ES cells were then transplanted into B6 mice to form teratomas. We used microarrays to profile the gene expression differences between the teratomas formed by B6 ES cells and EiPS cells. Pooled RNA from two teratomas formed by B6 ES or two regression teratomas formed by EiPS were selected for hybridization 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.
Project description:CD69 is a transmembrane protein expressed on the surface of activated leukocyte. The ligand for CD69 and the intracellular signaling pathway of this molecule are yet unknown. It is widely used as a marker of activated lymphocyte, but its function in immune system is not known. We used micro-array to define genes whose expression is regulated by activation antigene CD69. CD4 T cells were isolated from the spleen of wt B6 and CD69-deficient B6 mice and in vitro activated with anti-CD3/anti-CD28 coated beads. On one groupe of wt B6 cells, CD69 was activated using a anti-CD69 and secoundary antibody. RNA extraction and hybridization on Affymetrix microarrays was performed for wt B6, CD69-activated wt B6 and CD69-deficient B6 CD4 T cells.
