Description
We performed RNA_Seq on purified hair follicle stem cells (HFSCs)and their direct progenty, transit amplifying cells (TACs) using temorally and spatially regulated Cre lines. Overall design: Consequences of loss of Bmpr1a in either HFSC (K15-CrePGR;Bmpr1a fl/fl), or TACs (1. Shh-CreER:Bmpr1a fl/fl or 2. K15-CrePGR;Bmpr1a fl/fl derived)
Publication Title

Affymetrix Mouse Genome 430 2.0 Array (mouse4302)
Description
EphB receptors regulate the proliferation and positioning of intestinal stem and progenitor cells. In addition, they can act as tumor promoters for adenoma development, but suppress progression to invasive carcinoma. Here we used imatinib to abrogate Abl kinase activity in ApcMin/+ mice and in mice with LGR5+ stem cells genetically targeted for APC. This treatment inhibited the tumor-promoting effects of EphB signaling without attenuating EphB-mediated tumor suppression, demonstrating the role of EphB signaling in intestinal tumor initiation. The investigated treatment regimen extended the lifespan of ApcMin/+ mice, and reduced cell proliferation in cultured slices of adenomas from FAP patients. These findings connect the EphB signaling pathway to the regulation of intestinal adenoma initiation via Abl kinase. Our findings may have clinical implications for pharmacological therapy against adenoma formation and cancer progression in patients predisposed to develop colon cancer.
Publication Title
An EphB-Abl signaling pathway is associated with intestinal tumor initiation and growth.

Description
Facioscapulohumeral dystrophy (FSHD) is one of the most common inherited muscular dystrophies. The causative gene remains controversial and the mechanism of pathophysiology unknown. Here we identify genes associated with germline and early stem cell development as targets of the DUX4 transcription factor, a leading candidate gene for FSHD. The genes regulated by DUX4 are reliably detected in FSHD muscle but not in controls, providing direct support for the model that misexpression of DUX4 is a causal factor for FSHD. Additionally, we show that DUX4 binds and activates LTR elements from a class of MaLR endogenous primate retrotransposons and suppresses the innate immune response to viral infection, at least in part through the activation of DEFB103, a human defensin that can inhibit muscle differentiation. These findings suggest specific mechanisms of FSHD pathology and identify candidate biomarkers for disease diagnosis and progression.

Description
Vanin1, a regulator of vitamin B5 metabolism, is expressed by sarcoma tumors. We evaluated its impact on sarcoma growth by using sarcoma cell lines derived from p16p19Vnn1-deficient mice and further transduced with an oncogenic RasV12 oncogene (R tumors) in the presence or not of a catalytically active (VR tumors) or mutated (VdR tumors) Vnn1 isoform.

Description
Context: In many cancers, specific subpopulations of cells appear to be uniquely capable of initiating and maintaining tumors. The strongest support for this cancer stem cell model comes from transplantation assays in immune-deficient mice indicating that human acute myeloid leukemia (AML) is organized as a cellular hierarchy driven by self-renewing leukemia stem cells (LSC). This model has significant implications for the development of novel therapies, but its clinical significance remains unclear.
