Description
We identified genes whose expression changes between stage 8 and stage 10. We also identified genes whose expression was altered in stage 10 from temperature senstive ecdysone receptor mutant flies raised at the restrictive temperature. The experiments showed a significant number of genes that are upregulated in stage 10 depend EcR-mediated signaling. Overall design: 3 samples x 3 repeats

Description
ALTERED MERISTEM PROGRAM1 (AMP1) is a member of the M28 family of carboxypeptidases with a pivotal role in cell fate maintenance in the embryo and shoot meristem. A defect in AMP1 function results in suspensor to embryo conversion and a hypertrophic shoot meristem forming ectopic stem cell pools. However, so far the role of AMP1 in shoot development could not be assigned to a specific molecular pathway nor is its biochemical function resolved. Double mutants in CYP78A5 and CYP78A7 develop a similar set of cell fate defects. To further assess whether this phenotypic overlap is also depicted in a congruency at the global gene expression level, we analyzed the transcriptomic responses of both genotypes

Description
Interleukin-17 (IL-17) is essential in host defense against extracellular bacteria and fungi, especially at mucosal sites, but it also contributes significantly to inflammatory and autoimmune disease pathologies. Binding of IL-17 to its receptor leads to recruitment of the adaptor protein CIKS/Act1 via heterotypic association of their respective SEFIR domains and to activation of the transcription factor NF-kB; it is not known whether CIKS and/or NF-kB are required for all gene induction events. Here we report that CIKS is essential for all IL-17 induced immediate-early genes in primary mouse embryo fibroblasts, while NF-kB is profoundly involved. We also identify a novel sub-domain in the N-terminus of CIKS that is essential for IL-17-mediated NF-kB activation. This domain is both necessary and sufficient for the interaction between CIKS and TRAF6, an adaptor required for NF-kB activation. The ability of decoy peptides to block this interaction may provide a new therapeutic strategy for intervention in IL-17-driven autoimmune and inflammatory diseases.

Description
hEPI-NCSC are neural crest derived multipotent somatic stem cells that persist in hair follicle stem cell niche, termed the bulge, and persist into adulthood (Clewes O et al, 2011). The purpose of this project was to generate two gene expression profiles, (1) of ex vivo expanded hEPI-NCSC (XP) and (2) of cells, whihc after expansion were grown in a culture medium (NP1), which was empirically designed to pre-differentiate the multipotent stem cells into neural stemcell like cells.

Description
Graft-versus-host disease (GVHD) is the most serious complication of allogeneic hematopoietic cell transplantation. Notch signals delivered during the first 48 hours after transplantation drive proinflammatory cytokine production in conventional T cells (Tconv) and inhibit expansion of regulatory T cells (Tregs). Short-term Notch inhibition induces long-term GVHD protection. However, it remains unknown whether Notch blockade blunts GVHD through its effects on Tconv, Tregs, or both, and what early Notch-regulated molecular events occur in alloantigen-specific T cells. To address these questions, we engineered T cell grafts to achieve selective Notch blockade in Tconv vs. Tregs and evaluated their capacity to trigger GVHD in mice. Notch blockade in Tconv was essential for GVHD protection, as GVHD severity was similar in recipients of wild-type Tconv combined with Notch-deprived vs. wild-type Tregs. To identify the impact of Notch signaling on the earliest steps of T cell activation in vivo, we established a new acute GVHD model mediated by clonal alloantigen-specific 4C CD4+ Tconv. Notch-deprived 4C T cells had preserved early steps of activation, IL-2 production, proliferation, and T helper polarization. In contrast, Notch inhibition dampened IFN-? and IL-17 production, diminished mTORC1 and ERK1/2 activation, and impaired transcription of a subset of Myc-regulated genes. The distinct Notch-regulated signature had minimal overlap with known Notch targets in T cell leukemia and developing T cells, highlighting the specific impact of Notch signaling in mature T cells. Our findings uncover a unique molecular program associated with pathogenic effects of Notch in T cells at the earliest stages of GVHD. Overall design: 4 samples per cohort (Notch blockade using Dll1/4 neutralizing antibodies vs isotype control antibodies - GD) were analyzed. Additional 4 samples contained 4C T cells retrieved from syngeneic recipients.
