TranscriptomicsExpression profiling in the Drosophila eye reveals unexpected repression of Notch signaling by the JAK/STAT pathway
Although the JAK/STAT pathway regulates numerous processes in vertebrates and invertebrates through modulating transcription, its functionally-relevant transcriptional targets remain largely unknown. With one jak and one stat (stat92E), Drosophila provides a powerful system for finding new JAK/STAT ...

TranscriptomicsVreteno, a gonad-specific protein, is essential for germline development and primary piRNA biogenesis in Drosophila
In Drosophila, Piwi proteins associate with Piwi-interacting RNAs (piRNAs) and protect the germline genome by silencing mobile genetic elements. This defense system acts in germline and gonadal somatic tissue to preserve germline development. Genetic control for these silencing pathways varies great...

TranscriptomicsProfiling and Functional Analyses of MicroRNAs and Their Target Gene Products in Human Uterine Leiomyomas
Human uterine leiomyomas (ULM) are characterized by dysregulation of a large number of genes and non-coding regulatory microRNAs. In order to identify microRNA::mRNA associations relevant to ULM pathogenesis, we examined global correlation patterns between the altered microRNA expression and the pre...

TranscriptomicsDNA Damage Response and Inflammatory Signaling Limit the MLL-ENL-induced Leukemogenesis in vivo
Activation of the MLL-ENL-ERtm oncogene initiates aberrant proliferation of myeloid progenitors. Here, we show induction of a fail-safe mechanism mediated by the DNA damage response (DDR) machinery that results in activation of the ATR/ATM-Chk1/Chk2-p53/p21 checkpoint and cellular senescence at earl...

TranscriptomicsChromatin remodeling enzyme Brg1 is required for mouse lens fiber cell terminal differentiation and their denucleation [lens tissue]
Genome-wide approach to identify the cell-autonomous role of Brg1 in lens fiber cell terminal differentiation. To examine roles of Brg1 in mouse lens development, a dnBrg1 transgenic construct was expressed using the lens-specific alphaA-crystallin promoter in postmitotic lens fiber cells. Morpholog...

TranscriptomicsMolecular Signatures of Fetal and Adult Prostate Stem Cells
The global gene expression profiles of adult and fetal murine prostate stem cells were determined to define common and unique regulators whose misexpression might play a role in the development of prostate cancer. A distinctive core of transcriptional regulators common to both fetal and adult primit...

TranscriptomicsUGE and UGM Reveal Novel Signaling Pathways and Ligand-Receptor Interactions in the Primitive Prostate Stem Cell Niche
We isolated fetal murine urogenital sinus epithelium and urogenital sinus mesenchyme and determined their global gene expression profiles to define their differentially expressed regulators. To distinguish gene expression patterns that are shared by other developing epithelial/mesenchymal compartmen...

TranscriptomicsNon-targeted effects of low dose ionizing radiation act via TGF-beta to promote mammary carcinogenesis
This is a genome-wide approach to identifying genes persistently induced in the mouse mammary gland by acute whole body low dose ionizing radiation (10cGy), 1 and 4 weeks after exposure. Gene expression that is modified under these parameters were compared between Tgfb1 wild type and heterozygote li...

TranscriptomicsImmune profile and mitotic index of metastatic melanoma lesions enhance clinical staging in predicting patient survival.
Although remission rates for metastatic melanoma are generally very poor, some patients can survive for prolonged periods following metastasis. We used gene expression profiling, mitotic index (MI), and quantification of tumor infiltrating leukocytes (TILs) and CD3+ cells in metastatic lesions to se...

TranscriptomicsExpression data from LSK WT and LSK N1-C+
Notch signaling is one of the central regulators of differentiation in a variety of organisms and tissue types. Within the hematopoietic system, Notch is essential for the emergence of definitive HSC during fetal life and controls adult HSC differentiation to the T-cell lineage. Notch activation is ...
