An unbiased cDNA expression phage library derived from bone-marrow endothelial cells was used to identify novel surface adhesion molecules that might participate in metastasis. Herein we report that reticulocalbin 1 (RCN1) is a cell surface-associated protein on both endothelial (EC) and prostate cancer (PCa) cell lines. RCN1 is an H/KDEL protein with six EF-hand, calcium-binding motifs, found ...
Vascular endothelial cells (ECs) play important roles in the regulation of vascular functions. Loss of endothelial integrity can lead to vascular diseases such as stenosis resulting from atherosclerosis. The migration of ECs into wounded area in the vessel wall is required for the restoration of its integrity and functions. EC migration results from a balance of externally applied forces (e.g. ...
OBJECTIVE Thioredoxin-interacting protein (TXNIP) promotes inflammation in endothelial cells (EC) by binding to thioredoxin-1 (TRX1) in a redox-dependent manner. Formation of the TXNIP-TRX1 complex relieves inhibition of the apoptosis signal-regulating kinase 1-c-Jun N-terminal kinase-vascular cell adhesion molecule-1 pathway. Because TXNIP is an α-arrestin with numerous protein-protein interac...
Endothelial cells (EC) play a major role in tumor-induced neovascularization and bridge the gap between a microtumor and growth factors such as nutrients and oxygen supply required for expansion. Immortalized human microvascular endothelial cells (HMEC-1) were utilized to assess anti-endothelial effects of 10 novel potential cancer chemopreventive compounds from various sources that we have inv...
Vascular endothelial cells (EC) and smooth muscle cells (SMC) require a decrease in cytoplasmic Ca2+ concentration after activation. This can be achieved by Ca2+ sequestration by the sarco-/endoplasmic reticulum Ca2+ pumps (SERCA) and Ca2+ extrusion by plasma membrane Ca2+ pumps (PMCA) and Na+-Ca2+-exchangers (NCX). Since the two cell types differ in their structure and function, we compared th...
RATIONALE Endothelial microRNA-126 (miR-126) modulates vascular development and angiogenesis. However, its role in the regulation of smooth muscle cell (SMC) function is unknown. OBJECTIVE To elucidate the role of miR-126 secreted by endothelial cells (ECs) in regulating SMC turnover in vitro and in vivo, as well as the effects of shear stress on the regulation. METHODS AND RESULTS Cocultur...
Reactive oxygen species (ROS) have a crucial role in stem-cell differentiation; however, the mechanisms by which ROS regulate the differentiation of stem cells into endothelial cells (ECs) are unknown. Here, we determine the role of ROS produced by NADPH oxidase 2 (Nox2) in the endothelial-lineage specification of mouse induced-pluripotent stem cells (miPSCs). When wild-type (WT) and Nox2-knock...
New blood forming vessels are produced by differentiation of mesodermal precursor cells to angioblasts that become endothelial cells (ECs) which in turn give rise to primitive capillary network. Human cord blood (HCB) contains large subsets of mononuclear cells (MNCs) that can be differentiated into endothelial-like cells in vitro. Human mononuclear progenitor cells were purified from fresh umb...
PURPOSE Corneal endothelial cells (EC) are crucial for maintaining corneal clarity before and after keratoplasty. Since it is thought that corneal graft rejection leads to irreversible EC loss and transplant failure, we quantified immune mediated EC loss in the rat keratoplasty model and analyzed whether the EC layer would then regenerate. METHODS Rats were subjected to orthotopic penetrating...
Platelet endothelial cell adhesion molecule-1 (PECAM-1/CD31) is a member of the immunoglobulin superfamily of cell adhesion molecules with important roles in angiogenesis and inflammation. However, the molecular and cellular mechanisms, and the role that specific PECAM-1 isoforms play in these processes, remain elusive. We recently showed attenuation of retinal vascular development and neovascu...
