Genome-wide profiling of endothelial progenitor cells in multiple myeloma

ABSTRACT: In multiple myeloma (MM), endothelial progenitor cells (EPCs) regulate tumor angiogenesis and disease progression. EPCs from 20 newly diagnosed patients with advanced MM were examined for genomic instability by RNA microarrays to assess changes in gene expression. EPCs were derived from single-cell suspensions of bone marrow (BM) aspirates from newly diagnosed MM patients, and RNA was extracted for microarray hybridization.

Genome-wide array comparative genomic hybridization (aCGH) profiling of endothelial progenitor cells, and their comparison to tumor plasma cells, in multiple myeloma

Project description:In multiple myeloma (MM), endothelial progenitor cells (EPCs) regulate tumor angiogenesis and disease progression. EPCs from 16 newly diagnosed patients with advanced MM were examined for genomic instability by aCGH to assess chromosomal gains and losses. Data were compared to aCGH results from corresponding CD138+ tumor plasma cells from these patients. EPCs and tumor cells were derived from single-cell suspensions of bone marrow (BM) aspirates from newly diagnosed MM patients, and total genomic DNA was extracted for aCGH. DNA from healthy male peripheral blood mononuclear cells (PBMCs; Promega, Madison, WI) was used as the normal control DNA.

Project description:in this study we evaluated the initial response promoted by the atherosclerotic plaque (AP) secreted factors over healthy endothelial progenitor cells (EPCs), in order to understand the mechanisms underlying the neovascularization and vascular remodeling properties assigned to these cells and to use them as cell therapy in cardiovascular diseases.

Genome-wide profiling of tumor cells in multiple myeloma

Project description:In multiple myeloma (MM), endothelial progenitor cells (EPCs) regulate tumor angiogenesis and disease progression. They share a common bone marrow microenvironment with myeloma tumor cells. CD138+ tumor plasma cells from 12 newly diagnosed patients with advanced MM were examined for genomic instability by RNA microarrays to assess changes in gene expression. Tumor cells were derived from single-cell suspensions of bone marrow (BM) aspirates from newly diagnosed MM patients, and RNA was extracted for microarray hybridization.

Expression data from human healthy EPCs/CACs

Project description:Systemic lupus erythematosus (SLE) is characterized by increased vascular risk due to premature atherosclerosis independent of traditional risk factors. We previously proposed that interferon-? plays a crucial role in premature vascular damage in SLE. IFN-? alters the balance between endothelial cell apoptosis and vascular repair mediated by endothelial progenitor cells (EPCs) and myeloid circulating angiogenic cells (CACs). Here we demonstrate that IFN-? promotes an antiangiogenic signature in SLE and control EPCs/CACs, characterized by transcriptional repression of IL-1? and ?, IL-1 receptor 1 and vascular endothelial growth factor A (VEGF-A) and upregulation of IL-1 receptor antagonist (IL-1RN) and the decoy receptor IL1-R2. IL-1? promotes significant improvement in the functional capacity of lupus EPCs/CACs, therefore abrogating the deleterious effects of IFN-?. We used microarrays to analyze the effect of IFN? on peripheral blood EPCs/CACs and on bone marrow EPCs exposed to proangiogenic stimulation. Human healthy EPCs and CACs from PBMCs were isolated and cultured under proangiogenic stimulation; after IFNa incubation or not, RNA was extracted and processed for hybridization on Affymetrix microarrays.

Expression data from human healthy and lupus EPCs/CACs, and healthy CD133+ bone marrow EPCs

Project description:Systemic lupus erythematosus (SLE) is characterized by increased vascular risk due to premature atherosclerosis independent of traditional risk factors. We previously proposed that interferon-α plays a crucial role in premature vascular damage in SLE. IFN-α alters the balance between endothelial cell apoptosis and vascular repair mediated by endothelial progenitor cells (EPCs) and myeloid circulating angiogenic cells (CACs). Here we demonstrate that IFN-α promotes an antiangiogenic signature in SLE and control EPCs/CACs, characterized by transcriptional repression of IL-1α and β, IL-1 receptor 1 and vascular endothelial growth factor A (VEGF-A) and upregulation of IL-1 receptor antagonist (IL-1RN) and the decoy receptor IL1-R2. IL-1β promotes significant improvement in the functional capacity of lupus EPCs/CACs, therefore abrogating the deleterious effects of IFN-α. We used microarrays to analyze the effect of IFNα on peripheral blood EPCs/CACs and on bone marrow EPCs exposed to proangiogenic stimulation. This SuperSeries is composed of the SubSeries listed below. Human healthy and lupus EPCs and CACs from PBMCs, and healthy EPCs from bone marrow, were isolated and cultured under proangiogenic stimulation; after IFN-α incubation or not, RNA was extracted and processed for hybridization on Affymetrix microarrays.

Genome-wide analysis of each stage of EPCs differentiation

Project description:Analysis of regulators of endothelial progenitor cells (EPCs) differentiation at gene expression level. Results provide information of gene expression pattern and critical biological processing during EPCs differentiation. Taken together, we define the network of regulators of cord blood-derived EPCs during EPCs differentiation, which can be used to identify genes involved in vascular pathology. Furthermore, we select the critical regulators and then observe these selected regulator's functionality in vitro and in vivo. Total RNA obtained from isolated cord blood-derived EPCs at different time points after the beginning of the EPCs culture under endothelial differentiation condition.
