Description
In addition to KIT and PDGFRA mutations, sequential accumulation of other genetic events is involved in the development and progression of gastrointestinal stromal tumors (GISTs). Until recently, the significance of these other alterations has not been thoroughly investigated. The combination of gene expression profiling and high-resolution genomic copy number analysis offers a detailed molecular portrait of GISTs, providing an essential comprehensive knowledge necessary to guide the discovery of novel target genes involved in tumor development and progression.

- Affymetrix Mouse Gene 1.0 ST Array (mogene10st)
Description
We surveyed the transcriptomes of the whole heart and whole gastrocnemius muscle taken from two different types of Balb/c-DBAj hybrid mice (10-11 weeks old). The colon cancer bearing mice are called C26. The NTB are the non-tumor bearing mice.

Description
Purpose: Identify genes and pathways affected in tuft embryos with NTDs Results: Expression of genes associated with neural tube closure and components of non-canonical WNT signaling/PCP pathways were affected Conclusions: TET1 regulates genes associated with neural tube closure Overall design: RNA pooled from the rostrums of E9 (18-22 somites) tuft/tuft embryos with NTD compared with respective wildtype background strain
Publication Title
A mutation in the tuft mouse disrupts TET1 activity and alters the expression of genes that are crucial for neural tube closure.

Description
To identify biosignatures that describe these lifestyle susceptibility factors, we performed parallel exposures of regular weight (RW) C57BL/6 and diet-induced obese (DIO) C57BL/6 mice to cigarette smoke, either mainstream (MS) or sidestream (SS), mimicking both the smoker and environmental exposure through second-hand smoke, respectively.

Description
CTLA-4 is thought to inhibit effector T cells both intrinsically, by competing with CD28 for B7 ligands, and extrinsically, through the action of regulatory T cells. We studied in vivo responses of normal and CTLA-4-deficient antigen-specific murine effector CD4+ T cells. In order to do these studies in a physiological model of immunity to foreign antigen, we transferred small numbers of congenically marked RAG2-deficient 5C.C7 T cells with either a normal or knockout allele of CTLA-4 into normal syngeneic B10.A recipient mice. The T cells were then activated by immunization with MCC peptide and LPS. To look for transcriptional signatures of negative regulation of T cell responses by CTLA-4, we used microarray analysis to compare transcripts in wild type and CTLA-4 KO 5C.C7 T cells four days after immunization. This is the first instance in which differences are observed in extent of accumulation of wild type and CTLA-4 KO 5C.C7 T cells.

Description
We have previously shown that rheumatoid factors (RF) produced by Fas-deficient autoimmune-prone mice typically bind autologous IgG2a with remarkably low affinity. Nevertheless, B cells representative of this RF population proliferate vigorously in response IgG2a/chromatin immune complexes through a mechanism dependent on the sequential engagement of the BCR and Toll-like receptor 9 (TLR9). To more precisely address the role of both receptors in this response, we analyzed the signaling pathways activated in AM14 B cells stimulated with these complexes. We found that the BCR not only serves to direct the chromatin complex to an internal compartment where it can engage TLR9 but also transmits a suboptimal signal that in combination with the signals emanating from TLR9 leads to NF?B activation and proliferation. Importantly, engagement of both receptors leads to the upregulation of a group of gene products, not induced by the BCR or TLR9 alone, that include IL-2. These data indicate that autoreactive B cells, stimulated by a combination of BCR and TLR9 ligands, acquire functional properties that may contribute to the activation of additional cells involved in the autoimmune disease process.
Publication Title
Functional outcome of B cell activation by chromatin immune complex engagement of the B cell receptor and TLR9.
