Expression levels of the oxidized-LDL receptor LOX-1 have been related to cancer progression in prostatic, gastric, pancreatic, and colorectal (CRC); however, relationship among pro-inflammatory markers, ox-LDL/LOX-1 CRC are not completely elucidated. We tested hypothesis that stimulation cell lines with TNF-α ox-LDL promotes tumor progression. also explore effect on human colonoids growth. The...

Oxidized low-density lipoprotein (OxLDL) has been implicated in atherosclerosis and glomerulosclerosis. LOX-1 is a recently identified OxLDL receptor that is abundantly expressed in vascular endothelial cells. The aim of the present study was to investigate LOX-1 expression in the kidneys of hypertensive rats. Dahl salt-sensitive (DS) and salt-resistant (DR) rats were fed a 0.3% or 8% NaCl diet...

A novel lectin-like oxidized low density lipoprotein receptor-1 (LOX-1) was recently identified in bovine aortic endothelial cells. It is strongly suggested to have a potential role in the initiation and development of atherosclerosis. In this study, we have isolated cDNA clones encoding the rabbit homologue of LOX-1 by screening a rabbit placenta cDNA library. In amino acid sequence and domain...

BACKGROUND Lectin-like oxidized LDL receptor 1 (LOX-1) is implicated in atherothrombotic diseases. Activation of LOX-1 in humans can be evaluated by use of the LOX index, obtained by multiplying the circulating concentration of LOX-1 ligands containing apolipoprotein B (LAB) times that of the soluble form of LOX-1 (sLOX-1) [LOX index = LAB x sLOX-1]. This study aimed to establish the prognostic...

We hypothesized that the reciprocal association between adiponectin and lectin-like oxidized LDL (ox-LDL) receptor (LOX)-1 contributes to the regulation of aortic endothelial dysfunction in atherosclerosis. To test this hypothesis, endothelium-dependent (ACh) and endothelium-independent (sodium nitroprusside) vasorelaxation of isolated aortic rings from control mice, apolipoprotein E (ApoE) kno...

OBJECTIVE LOX-1, a novel lectin-like receptor for oxidized LDL (ox-LDL), is expressed in response to ox-LDL, angiotensin II (Ang II), tumor necrosis factor (TNF)-alpha, and other stress stimuli. It is highly expressed in atherosclerotic tissues. Peroxisome proliferator-activated receptor (PPAR)-gamma ligands, such as pioglitazone, exert antiatherosclerotic effects. This study examined the regul...

Lectin-like oxidized low-density lipoprotein receptor-1 (LOX-1) regulates growth of a variety of cells and is important in inflammation, oxidative stress, and tissue remodeling. Recent studies show that LOX-1 deletion limits cardiac remodeling after sustained hypertension. We posited that LOX-1 may affect cardiac fibroblast growth and collagen secretion. To examine this postulate, we studied gr...

LOX-1 is a multifunctional membrane receptor that binds and internalizes oxidized LDL (oxLDL). We tested the hypothesis that blockade of LOX-1 with an anti-LOX-1 antibody limits nephropathy in male rats with diabetes and dyslipidemia (ZS rats; F(1) hybrid product of Zucker fatty diabetic rats and spontaneous hypertensive heart failure rats). Lean ZS rats were controls, while untreated obese ZS ...

CONTEXT Serum concentration of oxidized low-density lipoprotein (oxLDL) is higher in women with preeclampsia than in normal pregnant woman. Lectin-like oxLDL receptor-1 (LOX-1) is one of the scavenger receptors for oxLDL and is abundantly expressed in placenta. It is well known that oxLDL activates nuclear factor erythroid 2-related factor 2 (Nrf2), a master regulator of antioxidant and cytopro...
