A comparative analysis of gene expression of CD4+ EGFP+ Nrp1+ (tTreg, thymus-derived Treg), CD4+ EGFP+ Nrp1- (pTreg, peripherally-derived Treg) and CD4+ EGFP- (Tconv, conventional T cell) in CD28-/- Foxp3EGFP and Foxp3EGFP mice. Overall design: Nrp1+ Treg (tTreg), Nrp1- Treg (pTreg) and Tconv were sorted from Foxp3EGFP and CD28-/-Foxp3EGFP mice. Total RNAs were extracted from whole samples and analyzed by RNA-seq.
CD28 co-stimulation is dispensable for the steady state homeostasis of intestinal regulatory T cells.

View SamplesWnt signaling is upregulated frequently in several cancers, including sarcomas. Since, there is cell-context dependent variation in the target gene expression, to identify canonical Wnt targets in sarcomas, we used human mesenchymal stem cells.
High-frequency canonical Wnt activation in multiple sarcoma subtypes drives proliferation through a TCF/β-catenin target gene, CDC25A.

View SamplesThe oviducts play a critical role in gamete and embryo transport, as well as supporting fertilization and early embryo development. Progesterone receptor (PGR) is a transcription factor highly expressed in oviductal cells, while its activating ligand, progesterone (P4), surges to peak levels as ovulation approaches. P4 is known to regulate oviduct cilia beating and muscular contractions in vitro, but how PGR may mediate this in vivo is poorly understood. We used PGR-knockout (PRKO) mice to determine how PGR regulates oviductal function during the periovulatory period, in particular oviductal transport and embryo support.

View SamplesOvulation requires sequential molecular events and structural remodeling in the ovarian follicle for the successful release of a mature oocyte capable of being fertilised. Critical to this process is progesterone receptor (PGR), a transcription factor highly yet transiently expressed in granulosa cells of preovulatory follicles. Progesterone receptor knockout (PRKO) mice are anovulatory, with a specific and complete defect in follicle rupture. Therefore, this model was used to examine the critical molecular and biochemical mechanisms necessary for successful ovulation.

View SamplesAbout 10% of Down syndrome (DS) infants are born with a myeloproliferative disorder (DS-TMD) that spontaneously resolves within the first few months of life. About 20-30% of these infants subsequently develop acute megakaryoblastic leukemia (DS-AMKL). In order to understand differences that may exist between fetal and bone marrow megakaryocyte progenitor cell populations we flow sorted megakaryocyte progenitor cells and performed microarray expression analysis.
Developmental differences in IFN signaling affect GATA1s-induced megakaryocyte hyperproliferation.

View SamplesSmall intestinal innate lymphoid cells (ILCs) are known to regulate intestinal epithelial cell homeostasis and to help prevent pathogenic bacterial infections, by producing IL-22. However, other functions of these cells and the lineal relationship between ILCs and lymphoid or myeloid cells have not been clear.
Intestinal Lin- c-Kit+ NKp46- CD4- population strongly produces IL-22 upon IL-1β stimulation.
