Description
We compare the transcriptome of embryonic stem cells (ESCs), adult stem cells with apparent greater differentiation potential such as multipotent adult progenitor cells (MAPCs), mesenchymal stem cells (MSCs) and neurospheres (NS). Mouse and rat MAPCs were used in this study and two different array platforms (Affymetrix and NIA) were used for mouse samples.

Description
Biased GPCR agonists are orthosteric ligands that possess pathway-selective efficacy, activating or inhibiting only a subset of the signaling repertoire of their cognate receptors. In vitro, D-Trp12,Tyr34-bPTH(7-34) (PTH-{beta}arr), a biased agonist for the type 1 parathyroid hormone receptor, antagonizes receptor-G protein coupling but activates arrestin-dependent signaling. In vivo, both PTH-{beta}arr and the conventional agonist PTH(1-34) stimulate anabolic bone formation. To understand how two PTH1R ligands with markedly different in vitro efficacy could elicit similar in vivo responses, we analyzed transcriptional profiles from calvarial bone of mice treated for 8 weeks with vehicle, PTH-{beta}arr or PTH(1-34). Treatment of wild type mice with PTH-{beta}arr primarily affected pathways that promote expansion of the osteoblast pool, notably cell cycle regulation, cell survival and migration. These responses were absent in beta-arrestin2 null mice, identifying them as downstream targets of beta-arrestin2-mediated signaling. In contrast, PTH(1-34) primarily affected pathways classically associated with enhanced bone formation, including collagen synthesis and matrix mineralization. PTH(1-34) actions were less dependent on beta-arrestin2, as might be expected of a ligand capable of G protein activation. These results illustrate the uniqueness of biased agonism in vivo and demonstrate that functional selectivity can be exploited to change the quality of GPCR efficacy.

Description
Evaluation of transcriptional changes in the striatum may be an effective approach to understanding the natural history of changes in expression contributing to the pathogenesis of Huntington disease (HD). We have performed genome-wide expression profiling of the YAC128 transgenic mouse model of HD at 12 and 24 months of age using two platforms in parallel; Affymetrix and Illumina. We performed gene expression profiling on the same striatal mRNA across both platforms.

Description
Gene expression profiling was carried out on splenocyte mRNA samples collected from 10 animals subject to repeated social threat (pooled into 2 groups of 5) and 10 animals subject to non-threatening control conditions (pooled into 2 groups of 5). The primary research question is whether gene expression differs in CD11b+ splenocytes from animals exposed to social threat vs non-threatening control conditions.

Description
small RNA libraries from wild-type and Hen1 mutant testes were made with either polyA tailing (VASAGFPHen1minus/plus) or adapter ligation (Hen1Testis and WTTestis) and sequenced on an Illumina GAII platform. Overall design: RNA was isolated from total testis tissue of both Hen1 wildtype and Hen1 mutant animals. After size selection from gel, the small RNA libraries wre made.

Description
Tumor cell survival critically depends on heterotypic communication with benign cells in the microenvironment. Here we describe a novel survival signaling pathway activated in stromal cells by contact to B-cells from chronic lymphocytic leukemia (CLL) patients. The expression of PKC-II and the subsequent activation of NF-B in bone marrow stromal cells is a prerequisite to support the survival of malignant B-cells. PKC- knockout mice are insusceptible to CLL-transplantations, underscoring the in vivo significance of the PKC-II- NF-B signaling pathway in the tumor microenvironment. Upregulated stromal PKC-II in biopsies from CLL, breast- and pancreatic- cancer patients suggest that this pathway may commonly be activated in a variety of malignancies.
