Expression Data from Ets1/2 WT, Ets1KO, Ets2KO and Ets1/2 DKO endothelial cells

ABSTRACT: Angiogenesis is a highly orchestrated process involving complex crosstalk between several endothelial cell (EC) processes including cell cycle, cell survival and migration. Transcription factors ETS1 and ETS2 are required for EC functions necessary for embryonic angiogenesis. However owing to the lethal nature of the double mutant embryo, the specific gene targets of these factors are yet to be identified. In the current study, we try to elucidate the effect of endothelial cell specific deletion of Ets1 and Ets2 on post natal angiogenesis and characterize the downstream regulatory pathways. Deletion of Ets1 and Ets2, restricted to endothelial cells in new born mice (P1-P3), reduced retinal angiogenesis. Similarly, EC infiltration and invasion into matrigel plugs subsided when matrigel admixed with mouse mammary tumor cells was injected into adult mice with inactivated Ets1 and Ets2 specifically in ECs. Expression of key cell cycle and cell survival regulators were diminished in double mutant cells as compared to controls. In addition, both these factors were found to occupy the enhancer regions of the target genes. Deletion of Ets1 and Ets2 in cultured aortic EC resulted in altered cell cycle phases with a G2/M phase arrest and increased sensitivity to apoptosis in vitro. These results demonstrate that deletion of Ets1 and Ets2 in endothelial cells inhibits angiogenesis by altering cell cycle progression and decreasing cell survival.

Interaction with ZMYND11 mediates opposing roles of Ras-responsive transcription factors ETS1 and ETS2

Project description:Aberrant activation of RAS/MAPK signaling is a driver of over one third of all human carcinomas. The homologous transcription factors ETS1 and ETS2 mediate the activation of gene expression programs downstream of RAS/MAPK signaling. ETS1 is important for oncogenesis in many tumor types. However, ETS2 can act as an oncogene in some cellular backgrounds, and as a tumor suppressor in others, and the molecular mechanism responsible for this cell-type specific function remains unknown. Here, we show that ETS1 and ETS2 regulate a cell migration gene expression program in opposite directions, and provide the first comparison of the ETS1 and ETS2 cistromes. This genomic data, and an ETS1 deletion line are used to show that the opposite function of ETS2 is due to binding site competition and a weaker activation function of ETS2 compared to ETS1. This weaker activation was mapped to the ETS2 N-terminus and a specific interaction with the co-repressor BS69 (ZMYND11). Gene expression data from tumor cohorts was then used to show that BS69 expression level in tumors correlates with oncogenic and tumor suppressive roles of ETS2. Therefore, these data indicate a novel and specific mechanism allowing ETS2 to switch between oncogenic and tumor suppressive functions in a cell-type specific manner.

VEGF promotes RNAPII pausing release through ETS1 to stimulate angiogenesis

Project description:RNA polymerase II (RNAPII) pausing release is a recently recognized checkpoint for transcriptional regulation. The biological roles of RNAPII pausing release and the mechanisms that by which extracellular signals control it are incompletely understood. Here we identify a novel mechanism by which VEGF stimulates RNAPII pausing-release through acetylation of ETS1, a master endothelial cell transcriptional regulator. In endothelial cells (ECs), ETS1 uniquely bound transcribed gene promoters and stimulated their expression by broadly increasing RNA polymerase II (RNAPII) pause release. VEGF enhanced ETS1 chromatin occupancy. Furthermore, VEGF increased ETS1 acetylation, enhancing its binding by BRD4 and thereby stimulating RNAPII pause release. This ETS1-mediated transduction of VEGF signaling to increase RNAPII pausing release was essential for EC angiogenic responses in vitro and in vivo. Together, our results define a new angiogenic pathway in which VEGF enhances ETS1-Brd4 interaction to broadly promote RNAPII pause release and drive angiogenesis.

Lack of adrenomedullin in mouse endothelial cells results in defective angiogenesis, enhanced vascular permeability, less metastasis, and more brain damage

Project description:Adrenomedullin (AM) is a vasodilating peptide involved in the regulation of circulatory homeostasis and in the pathophysiology of certain cardiovascular diseases. AM plays critical roles in blood vessels, including regulation of vascular stability and permeability. To elucidate the autocrine / paracrine function of AM in endothelial cells in vivo. A conditional knockout of AM in endothelial cells (AM EC-KO) was used. The amount of vascularization the matrigel implants was lower in AM EC-KO mice indicating a defective angiogenesis. Moreover, ablation of AM in endothelial cells revealed increased vascular permeability in comparison with wildtype littermates. In addition, AM EC-KO lungs exhibited significantly less tumor growth than littermate WT mice using a syngeneic model of metastasis. Furthermore, following middle cerebral artery permanent occlusion, there was a significant infarct size decrease in animals lacking endothelial AM when compared to their wild type counterparts. AM is an important regulator of EC function, angiogenesis, tumorigenesis and brain response to ischemia. Studies of AM should bring novel approaches to the treatment of vascular diseases. Lung endothelial mRNA profiles of wild type (WT) and adrenomedullin endothelial cell conditional knockout (AM EC-KO) mice were generated by deep sequencing using Illumina GAIIx.

Expression Data from Endothelial Cells as a Consequence of Ets2 Signaling in PyMT Tumor Associated Fibroblasts

Project description:Tumor associated fibroblasts are known to play an important role in angiogenesis, however the specific signaling pathways playing an important role in this cross talk remain ill defined. Here, we studied how Ets2 transcrpiton factor signaling in tumor associated fibroblasts effected gene expression in surrounding endothelial cells in the MMTV-PyMT mammary tumor model. Inactivation of Ets2 specifically in fibroblasts using Fsp-cre significantly reduced tumor associated angiogenesis, and was indicated to effect ECM remodeling, cell adhesion and cell chemotaxis processes in neighboring endothelial cells. We have identified Ets2 in fibroblasts as a key signaling molecule to induce tumor associated angiogenesis. Additionally, this function does not rely on the presence of tumor cells, indicating a memory in fibroblasts to induce angiogenesis. Primary mammary endothelial cells were isolated from mice with or without fibroblast Ets2 in the presence of the PyMT oncogene through sorting with a CD31 antibody. RNA was extracted and samples were submitted for Affymetrix gene expression arrays
