Affymetrix Human Genome U133 Plus 2.0 Array (hgu133plus2)
Description
While the response to G-CSF is a significant predictor of AML outcome, the nature of cells responding differentially to this and other cytokines remains unclear. Based on gene expression signatures observed in G-CSF Responsive Cells (RC) and non-G-CSF Responsive Cells (NRC) a cohort of AML samples were segregated into two types. In Type1 both cell subsets displayed an undifferentiated phenotype. In the Type2 AML the RC showed a very similar undifferentiated progenitor-like phenotype as in Type1 RC, whereas the NRC exhibited a more differentiated hematopoietic phenotype. The frequency of RC per sample was a determinant of whether a patient belonged to Type1 or Type2. Type2 RC had higher expression of CD321, higher colony formation capacity and greater responsiveness to cytokines secreted by NRC. Further analysis of clinical mRNA databases revealed that CD321 was a prognostic indicator for AML and a potential marker of clonogenic activity associated with this AML cancer lineage.

Description
In the nervous system, neural stem cells (NSC) are necessary for the generation of new neurons and for cognitive function. Here we show that FoxO3, a member of a transcription factor family known to extend lifespan in invertebrates, regulates the NSC pool. We find that adult FoxO3-/- mice have fewer NSC in vivo than wild type counterparts. NSC isolated from adult FoxO3-/- mice have decreased self-renewal and an impaired ability to generate different neural lineages. Identification of the FoxO3-dependent gene expression profile in NSC suggests that FoxO3 regulates the NSC pool by inducing a program of genes that preserves quiescence, prevents premature differentiation, and controls oxygen metabolism. The ability of FoxO3 to prevent the premature depletion of NSC might have important implications for counteracting brain aging in long-lived species.

Description
After 8 days of OKSM induction via doxycycline, Nanog-Neo secondary MEFs (Wernig et al. Nature Biotechnology 2008) were FACS sorted by KLF4, Oct4, and EpCAM expression. Four major subsets of MEFs have been sorted and analysed for gene expression.

- Affymetrix Mouse Gene 1.0 ST Array (mogene10st)
Description
This file contains gene microarray data from FACS purified mouse high endothelial cells and capillary endothelial cells from peripheral lymph nodes, mesenteric lymph nodes, and Peyers patches. The data will allow for better understanding of the specialization of high endothelial venules (HEV) and their role in lymphocyte recruitment from the blood; the tissue-specific differentiation of lymphoid tissue vasculature; and the specialized features of capillary vs. post-capillary endothelium, including differences in signaling pathways, adhesive properties and mechanisms of hemostasis.

Transcriptional programs of lymphoid tissue capillary and high endothelium reveal control mechanisms for lymphocyte homing.

Description
Mouse lung cancers were generated using the KrasLA model, in which a latent mutated Kras2 allele (resulting in the amino acid substitution G12D) is sporadically activated through spontaneous homologous recombination. These mice develop lung adenomas with full penetrance; over time, the tumors acquire morphologic characteristics reminiscent of those of human adenocarcinoma, such as nuclear atypia and a high mitotic index.
Publication Title
