Description
We used microarrays to detail the global programme of gene expression underlying the effect of sleep deprivation in the mouse hippocampus and identified distinct classes of regulated genes during this process.

Description
We generated three kinds of genetically identical mouse reprogrammed cells: induced pluripotent stem cells (iPSCs), nuclear transfer embryonic stem cells (ntESCs) and iPSC-nt-ESCs that are established after successively reprogramming of iPSCs by nuclear transfer (NT). NtESCs show better developmental potential than iPSCs, whereas iPSC-nt-ESCs display worse developmental potential than iPSCs.
Publication Title
Different developmental potential of pluripotent stem cells generated by different reprogramming strategies.

Description
After positive selection in the thymus, the newly generated single positive (SP) thymocytes are phenotypically and functionally immature and undergo apoptosis upon antigen stimulation. In the thymic medullary microenvironment, SP cells progressively acquire immunocompetence. Negative selection to remove autoreactive T cells also occur at this stage. We have defined four subsets of CD4 SP, namely, SP1, SP2, SP3, and SP4 that follow a functional maturation program and a sequential emergence during mouse ontogeny.

Description
The goal of this project was to characterize DCs from lymphopenic mice, like RAG (recombination activated gene) deficient mice and to examine the influence of mature B and T cells on the antigen presenting ability of splenic cDCs. We demonstrate how cellular cross-talk can shape the character and function of cDCs. Lymphopenic conditions, where splenic cDCs have to develop and differentiate, drastically change their character and their ability to cross-present soluble antigen.

Description
SMRT (silencing mediator of retinoid and thyroid hormone receptors) is recruited by numerous transcription factors to mediate lineage and signal dependent transcriptional repression. We generated a knock-in mutation in the receptor interaction domain (RID) of SMRT (SMRTmRID) that solely disrupts its interaction with nuclear hormone receptors. SMRTmRID-derived 3T3-MEFs display a dramatically increased adipogenic capacity and accelerated differentiation rate. We measured global gene expression in wild-type versus SMRTmRID-derived 3T3-MEFs in the undifferentiated state to examine which pathways were altered. Our results demonstrate that SMRT-RID dependent repression is a key determinant of the adipogenic set point.
Publication Title
SMRT repression of nuclear receptors controls the adipogenic set point and metabolic homeostasis.

Description
We present a robust serum-free system for the rapid and efficient reprogramming of mouse somatic cells by Oct4, Sox2 and Klf4. The elimination of fetal bovine serum and oncogene c-Myc allowed reprogramming cells to be detected as early as Day 2 and reached greater than 10% of the population at Day 7 post retroviral transduction. The resulting iPS colonies were isolated with high efficiency to establish pluripotent cell lines. Based on this method, we further developed iPS-SF1 as a dedicated reprogramming medium for chemical screening and mechanistic investigations.

Description
Medulloblastoma (MB) is the most common malignant brain tumor in children. Patients whose tumors exhibit overexpression or amplification of the MYC oncogene (c-MYC) usually have an extremely poor prognosis, but there are no animal models of this subtype of the disease. Here we show that cerebellar stem cells expressing Myc and mutant Trp53 (p53) generate aggressive tumors following orthotopic transplantation. These tumors consist of large, pleiomorphic cells and resemble human MYC-driven MB at a molecular level. Notably, antagonists of PI3K/mTOR signaling, but not Hedgehog signaling, inhibit growth of tumor cells. These findings suggest that cerebellar stem cells can give rise to MYC-driven MB, and identify a novel model that can be used to test therapies for this devastating disease.
