Affymetrix Mouse Genome 430 2.0 Array (mouse4302)
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
MDSC (myeloid-derived suppressor cells) can be differentiated in vitro using IL-6 and GM-CSF. To identify the specific role of IL-6 in this process, we used microarray to compare MDSC differentiated with IL-6 and GM-CSF to MDSC differentiated with GM-CSF alone. We have found genes and pathways that are up- or downregulated when IL-6 is present.

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
Culture medium of mesenchymal stromal cells (MSCs) is usually supplemented with either human platelet lysate (HPL) or fetal calf serum (FCS). Many studies have demonstrated that proliferation and cellular morphology is influenced by these additives hence they may favor outgrowth of specific subpopulations, thereby affecting the heterogeneous composition of MSCs. We have isolated and expanded human bone marrow derived MSCs in parallel with HPL or FCS for two passages. In HPL the proliferation was significantly higher and cells reflected more spindle-shaped morphology. Pairwise comparisons of gene expression profiles (Affymetrix HTA 2.0) revealed only moderate differences. When we apply a fold change >1.5 and limma-adjusted P-value of <0.05, only 69 transcripts were differentially expressed. These results indicate that there is no systematic bias for specific subpopulations of MSCs by using either HPL or FCS.

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
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
We generated primary cultures from renal cell carcinoma and matched normal primary kidney cortex tubule cell cultures from 3 patients. Early passage cultures of these two cell types were subjected to chromatin accessibility profiling (DNase-seq) and gene expression profiling (RNA-seq). Studying these paired and patient-matched controlled data sets will shed light on the epigenomic changes that underlie transformation of kidney tubules into malignant cancers. Overall design: Paired DNase-seq and RNA-seq data sets from 2 different primary human kidney cell types (normal and cancer) Note from submitter: The HIM23 samples have a more narrow consent and their raw data will be submitted to dbGaP.
