(Submitter supplied) Pericytes confer vascular stability in the retina, and the loss of pericytes can cause the blood-retina barrier breakdown seen in diabetic retinopathy. To identify endothelial-specific genes expressed in pericyte-deprived retinal vessels, we purified genetically labeled endothelial cells from Tie2-GFP transgenic mice treated with neutralizing antibody against PDGFRb (APB5) and performed gene expression profiling using DNA microarray. more...

(Submitter supplied) Deregulated retinal angiogenesis directly cause vision loss in many ocular diseases, such as diabetic retinopathy and retinopathy of prematurity. To identify endothelial-specific genes expressed in angiogenic retinal vessels, we purified genetically labeled endothelial cells from Tie2-GFP transgenic mice and performed gene expression profiling using DNA microarray. To find out genes associated with angiogenesis, comparisons of microarray data were carried out between GFP-negative non-endothelial retinal cells and GFP-positive retinal endothelial cells in angiogenic P8 retina.

(Submitter supplied) Intravasation, vascular dissemination and metastasis of malignant tumor cells require their passage over the vascular wall which is commonly composed of pericytes (mural cells) and the endothelial cell barrier. We currently decided to investigate the relative contribution of these cell types for B16F10 melanoma metastasis in mice using an experimental model of Shb gene inactivation. RNAseq of tumor endothelial cells from these mice revealed changes in cellular components such as adherens junctions and focal adhesions by gene ontology analysis that were in line with the observed effects on leakage and junction morphology.

(Submitter supplied) Vascular pericytes, an important cellular component, in the tumor microenvironment, are often associated with tumor vasculatures and their functions in cancer invasion and metastasis are poorly understood. Here we show that PDGF-BB induces pericyte fibroblast transition (designated as PFT), which significantly contributes to tumor invasion and metastasis. Gain- and loss-of-function experiments demonstrate that the PDGF-BB-PDGFRβ signaling promotes PFT in vitro and in in vivo tumors. more...

(Submitter supplied) The platelet-derived growth factor (PDGF) signaling system contributes to tumor angiogenesis and vascular remodeling. Here, we show PDGF-BB markedly induces erythropoietin (EPO) mRNA and protein expression by targeting the PDGFR-beta+ stromal and perivascular compartments. In mouse tumor models, PDGF-BB-induced EPO promotes tumor growth via two mechanisms: 1) paracrine stimulation of tumor angiogenesis by directly inducing endothelial cell proliferation, migration, sprouting and tube formation; and 2) endocrine stimulation of extramedullary hematopoiesis leading to increased oxygen perfusion and protection against tumor-associated anemia. more...

(Submitter supplied) Anti-PDGF agents are routinely used as a key component in front-line therapy for the treatment of various cancers. However, molecular mechanisms underlying their impact on vascular remodeling in relation to the dose issue remain poorly understood. Here we show that in high PDGF-BB-producing tumors, anti-PDGF drugs significantly inhibited tumor growth and metastasis by preventing pericyte (PC) loss and vascular permeability. more...

(Submitter supplied) We demonstrated that deletion of the p53 tumor suppressor gene in NG2 expressing cells resulted in the development of bone and soft tissue sarcomas that closely resemble human tumors. To determine gene expression differences between NG2 expressing pericytes lacking p53 and sarcomas that arose from deletion of p53 in NG2 expressing cells, RNA sequencing analysis was implemented.

(Submitter supplied) The functional role of tumor cell-expressed Angpt2 still remains elusive. Here, we used mouse melanoma cells which have endgeneous Angpt2 expression and invesitgated the functional role of tumor cell-derived Angpt2. Total RNA from control and Angpt2 silenced mouse melanoma cells (RET) was isolated and was further utilized for microarray analysis using Affymetrix Mouse Gene 2.0 ST array.

(Submitter supplied) Pericytes are integral components of the tissue vasculature and have essential functions in tumour angiogenesis. Endosialin (CD248) is a type I transmembrane glycoprotein highly expressed on pericytes in the tumour vasculature of most solid tumours, however it is low or negligibly expressed on normal tissue pericytes. Experiments using wild-type and endosialin-knockout mice has revealed that stromal endosialin expression facilitates intravasation of tumor cells from the primary tumor into the circulation, thereby promoting metastatic dissemination.
