TranscriptomicsHypoxia-induced Arterial Differentiation Requires Adrenomedullin and Notch Signaling
Hypoxia (low oxygen) and Notch signaling are two important regulators of vascular development, but how they interact in controlling the choice between arterial and venous fates for endothelial cells during vasculogenesis is less well understood. In this report, we show that hypoxia and Notch signali...

TranscriptomicsPhysiologic Hypoxia Promotes Maintenance of CML Stem Cells Despite Effective BCRM-bM-^HM-^RABL1 Inhibition
ABL1 kinase inhibitors such as imatinib mesylate (IM) are effective in managing chronic myelogenous leukemia (CML) but incapable of eliminating leukemia stem cells (LSCs), suggesting that kinaseM-bM-^HM-^Rindependent pathways support LSC survival. Given that the bone marrow hypoxic microenvironment ...

TranscriptomicsHeparan Sulfation Dependent FGF Signalling Maintains ES Cells Primed for Differentiation in a Heterogeneous State
Embryonic stem (ES) cells continuously decide whether to maintain pluripotency or differentiate. While exogenous LIF and BMP4 perpetuate a pluripotent state, less is known about factors initiating differentiation. We show that heparan sulfate (HS) proteoglycans are critical co-receptors for signals ...

TranscriptomicsGene expression profiles of dasatinib-resistant and dasatinib-sensitive pancreatic cancer cell lines
Gene profiles from three dasatinib-resistant and three dasatinib-sensitive pancreatic cancer cell lines were compared by microarray analysis. RNA from three dasatinib-resistant (MiaPaCa2, Panc1, SU8686) and three dasatinib-sensitive (Panc0504, Panc0403, Panc1005) pancreatic cancer cell lines were ex...

TranscriptomicsXenobiotics and loss of cell adhesion drives distinct transcriptional outcomes by Aryl hydrocarbon Receptor (AhR) signaling.
The Aryl hydrocarbon Receptor (AhR) is a signal regulated transcription factor, which is canonically activated by the direct binding of xenobiotics. In addition, switching cells from adherent to suspension culture also activates the AhR, representing a non-xenobiotic, physiological activation of AhR...

TranscriptomicsNon-canonical Notch signaling activates IL-6/JAK/STAT signaling in breast tumor cells and is controlled by p53 and IKKβ
Notch signaling is frequently hyperactivated in breast cancer, but how the enhanced signaling contributes to the tumor process is less well understood. In this report, we identify the proinflammatory cytokine interleukin-6 (IL-6) as a novel Notch target in breast tumor cells. Enhanced Notch signalin...

TranscriptomicsRole of the hypoxia-inducible histone H3K9 methylation regulating enzymes Jmjd1a and G9a in stem cell self-renewal and tumorigenesis
Hypoxia is one of the major driving forces mediating tumor angiogenesis, aggressiveness, as well as resistance to chemo- and radiotherapy. It has also been suggested to play important roles in stem cell maintenance for both normal and cancer tissues. However, the mechanisms by which hypoxia-driven e...
