Oxidized low density lipoprotein (ox-LDL) and its receptor, lectin-Like ox-LDL receptor-1 (LOX-1), play important roles in the development of endothelial injuries. Olmesartan can protect endothelial cells from the impairment caused by various pathological stimulations. In the present study we investigated whether olmesartan decreased the impairment of endothelial cells induced by ox-LDL by exer...

Lectin-like oxidized lipoprotein (OxLDL) receptor 1, LOX-1, is the major OxLDL receptor expressed on vascular endothelial cells. We have previously reported the ligand-recognition mode of LOX-1 based on the crystal structure of the ligand binding domain (C-type lectin-like domain, CTLD) and surface plasmon resonance analysis, which suggested that the functional significance of the CTLD dimer (t...

Renal cell carcinoma (RCC) represents around 3% of all cancers, within which clear RCC (ccRCC) are the most common type (70–75%). The disease regularly progresses asymptomatically and upon presentation is recurrently metastatic, therefore, an early method detection necessary. identification one or more specific biomarkers measurable in biofluids (i.e., urine) by combined approaches could surely...

Identification of keymolecules that drive angiogenesis is critical for the development of newmodalities for the prevention of solid tumor progression. Using multiple models of colorectal cancer, we show that activity of the extracellular matrix–modifying enzyme lysyl oxidase (LOX) is essential for stimulating endothelial cells in vitro and angiogenesis in vivo. We show that LOX activates Akt th...

Preeclampsia is a disorder of pregnancy with a significant impact on maternal and fetal health. The complexity of this multifactorial condition has precluded development of effective therapies and, although many potential pathways have been investigated, the etiology still requires clarification. Our group has investigated the scavenger lectin-like oxidized LDL (LOX-1) receptor, which may respo...

OBJECTIVE Chronic ischemia is associated with alterations in genes that result in myocardial remodeling. An important biochemical basis of cardiac remodeling is generation of reactive oxygen species (ROS). A few studies have suggested that acute ischemia triggers signals for remodeling. We examined the hypothesis that targeted deletion of lectin-like oxidized-LDL receptor (LOX-1) may inhibit si...

Objective(s): Arachidonic Acid/5-lipoxygenase (AA/5-LOX) pathway connects lipid metabolism and proinflammatory cytokine, which are both related to the development and progression of nonalcoholic fatty liver disease (NAFLD). Therefore, the present study was designed to investigate the role of AA/5-LOX pathway in progression of NAFLD, and the effect of zileuton, an inhibitor of 5-LOX, in this mod...

Lectin-like oxidized low-density lipoprotein receptor (LOX-1) is a newly identified endothelial cell surface major receptor for oxidatively modified low-density lipoprotein. Progression of arthrosclerosis in the donor organ after organ transplantation is a major problem. We hypothesized that ischemia-reperfusion induces LOX-1. After 1 h ischemia of bilateral kidneys plus 3, 6, or 12 h reperfusi...
