OBJECTIVE Ferlins are known to regulate plasma membrane repair in muscle cells and are linked to muscular dystrophy and cardiomyopathy. Recently, using proteomic analysis of caveolae/lipid rafts, we reported that endothelial cells (EC) express myoferlin and that it regulates membrane expression of vascular endothelial growth factor receptor 2 (VEGFR-2). The goal of this study was to document th...

Chemokine (CC motif) receptor-like 2 (CCRL2) binds leukocyte chemoattractant chemerin and can regulate local levels of the attractant, but does not itself support cell migration. In this study, we show that CCRL2 and VCAM-1 are upregulated on cultured human and mouse vascular endothelial cells (EC) and cell lines by proinflammatory stimuli. CCRL2 induction is dependent on NF-κB and JAK/STAT sig...

RATIONALE The participation of endothelial cells (EC) in many physiological and pathological processes is widely modeled using human EC cultures, but genetic manipulation of these untransformed cells has been technically challenging. Clustered regularly interspaced short palindromic repeats (CRISPR)/CRISPR-associated protein 9 nuclease (Cas9) technology offers a promising new approach. However,...

This study aimed to determine the effects of advanced glycation end products (AGEs) on endothelial cytoskeleton morphology and permeability, and to detect the underlying signaling mechanisms involved in these responses. Cultured endothelial cells (ECs) were exposed to AGE-modified human serum albumin (AGE-HSA), and EC cytoskeletal changes were evaluated by observing fluorescence of F-actin foll...

introduction as a tumor grows, the demand for oxygen and nutrients increases and it grows further if acquires the ability to induce angiogenesis. in this study, we aimed to present a two-dimensional continuous mathematical model for avascular tumor growth, coupled with a discrete model of angiogenesis. materials and methods in the avascular growth model, tumor is considered as a single mass, wh...

Excessive mechanical ventilation exerts pathologic mechanical strain on lung vascular endothelium and promotes endothelial cell (EC) inflammatory activation; however, the specific mechanisms underlying EC inflammatory response caused by mechanical ventilation related cyclic stretch (CS) remain unclear. This study investigated the effects of chronic exposure to CS at physiologic (5%) and patholo...

endothelial cell (HUVEC) and bovine aertic endothelial cell surface proteoglycans was significantly decreased by the incubation with SNAP andNOR4, poterrt nitric oxide (NO) donors. NO derived from lipopolysaccharide-stiinulated J774 A-1 cells also decreased the binding of EC-SOD to HUVEC, and this decrease was blocked by NG-nitro-L-arginine, a itric oxide synthase inhibiter. Furthermore. the de...

INTRODUCTION Endothelial dysfunction plays a critical role in the pathogenesis of cardiovascular diseases and cancer. Bone marrow-derived multipotent adult progenitor cells (MAPC) have the potential to differentiate, at the single cell level, toward the three embryonic germ layers and may be the progenitors of the other tissue-specific stem cells. However, molecular mechanisms of endothelial di...

Sepsis is a life-threatening condition often leading to multiple organ failure for which currently no pharmacological treatment available. Endothelial cells (EC) are among the first respond pathogens and inflammatory mediators in sepsis might be sentinel target prevent occurrence of failure. Lipopolysaccharide (LPS) Gram-negative bacterial component that induces endothelial expression adhesion ...

In vivo, MHC class I-restricted injury of allogeneic tissue or cells infected by intracellular pathogens occurs in the absence of classical cytolytic effector mechanisms and Ab. Modulation of the target cell adhesion to matrix may be an additional mechanism used to injure vascular or epithelial cells in inflammation. We studied the mechanisms of human umbilical vein endothelial cell (EC) detach...
