Description
AML1-ETO expression in normal human umbilical cord blood CD34+ cells leads to long-term proliferation of an early self-renewing primitive progenitor cell with multilineage potential and stem cell ability, but these cells do not induce leukemia in immunodeficient mice. This comparative microarray study was initiated to determine the differences in the transcriptome of AML-ETO-expressing CD34+ cells after extended culture in vitro, using normal cord blood cells expanded for 6-8 weeks in vitro and subsequently purified for the CD34+ population as the control comparison.

Description
Neuronal differentiation of PC12 cells in response to NGF is a prototypical model in which signal duration determines a biological response. Sustained ERK activity induced by NGF, as compared to transient activity induced by EGF, is critical to the differentiation of these cells. To characterize the transcriptional program activated preferentially by NGF, we compared global gene expression profiles between cells treated with NGF and EGF for 2-4 hrs, when sustained ERK signaling in response to NGF is most distinct from the transient signal elicited by EGF. This analysis identified 69 genes that were preferentially upregulated in response to NGF.
Publication Title
Global expression analysis identified a preferentially nerve growth factor-induced transcriptional program regulated by sustained mitogen-activated protein kinase/extracellular signal-regulated kinase (ERK) and AP-1 protein activation during PC12 cell differentiation.

Description
MLL-AF9 expression in normal human umbilical cord blood CD34+ cells leads to long-term proliferation of a myeloid progenitor cell with leukemogenic potential. Expression of a Core Binding Factor leukemia fusion (AML1-ETO or CBFbeta-SMMHC) in human CD34+ cells results in self-renewal of primitive progenitor cells with multilineage potential and stem cell ability, but these cells do not induce leukemia in immunodeficient mice. This comparative microarray study was initiated to determine how faithful these cell cultures are to the transcriptome of patient samples expressing each of these different fusion proteins, and to analyze the signaling pathways that are unique to CBF cultures and MLL-fusion cultures, with the hope of determining why the MLL-fusion cells are leukemogenic while the CBF cells are not.

Description
The pathogenesis of MLL-fusion gene leukemias has been linked to upregulated expression of HOX genes and of the HOX-cofactor Meis1.The functions of the HOX/MEIS1 complex in leukemia however remain unclear. Here, we used inducible MEIS1-knockout mice coupled with MLL-AF9 knockin mice to decipher the role of MEIS1 in leukemia. We found that MEIS1 was critically required for established leukemia. Further, MEIS1 loss led to increased oxygen flux and apoptosis, while hypoxia reversed these effects. Finally, we identify HLF as a downstream mediator of MEIS1 in leukemia. Overexpression of HLF prevents oxygen flux and rescues the leukemia phenotype in MEIS1-deficient cells. Thus, the oncogenic effects of MEIS1 are at least partly mediated by an HLF-driven hypoxic state. Overall design: Mouse bone marrow MLL-AF9 knockin cells of conditional Meis1f/f or control genotypes were treated with vehicle or 1000 nM of 4-hydroxy tamoxifen for 24 hours in IMDM with 10% FBA and 10 ng/ml of murine GM-CSF, IL-3, IL-6, SCF. RNA was isolated from treated cells and submitted to gene expression and sequencing core of Cincinnati Children''s Hospital & Medical Center. A total of four samples were included, and two groups were assisgned. Comparison comprises mRNA expression profile of vehicle and 4-OHT treatment in control cells versus Meis1-deleted cells.

Description
We report differences in mRNA gene expression in rectal biopsies from MSM compared to controls and for MSM timed with episodes of CRAI. Overall design: Rectal biopsies were obtained from MSM at two study timepoints: 1. after who abstaining from CRAI for >72 hours and 2.after engaing in CRAI within the last 24 hours. Rectal biopsies were also obtained from men who never engaged in AI.

Description
The goal of this study was to identify potential AMH-induced genes and regulatory networks controlling regression by RNA-Seq transcriptome analysis of differences in Müllerian Duct mesenchyme between males (AMH signaling on) and females (AMH signaling off) in purified fetal Müllerian Duct mesenchymal cells. This analysis found 82 genes up-regulated in males during MD regression and identified Osterix (Osx)/Sp7, a key transcriptional regulator of osteoblast differentiation and bone formation, as a novel downstream effector of AMH signaling during MD regression. Overall design: Müllerian Duct mesenchymal cells mRNA profiles from 2-7 embryonic day 14.5 embryos were generated by deep sequencing, in triplicate, using Illumina HiSeq 2000.
