OBJECTIVE LOX-1 is a multi-ligand receptor originally identified as the endothelial oxidized LDL receptor. LOX-1 expression is also induced in smooth muscle cells in response to proinflammatory and oxidative stimuli. Here, we report on the role of LOX-1 in intimal hyperplasia, in which proinflammatory and oxidative stimuli are increased. METHODS AND RESULTS Left common carotid artery of rat w...
We previously reported that the role of reactive oxygen intermediates (ROIs) in NF-kappaB activation by proinflammatory cytokines was cell specific. However, the sources for ROIs in various cell types are yet to be determined and might include 5-lipoxygenase (5-LOX) and NADPH oxidase. 5-LOX and 5-LOX activating protein (FLAP) are coexpressed in lymphoid cells but not in monocytic or epithelial ...
Endothelial dysfunction, or activation, elicited by oxidized low density lipoprotein (Ox-LDL) and its lipid constituents has been shown to play a key role in the pathogenesis of atherosclerosis. We recently have identified a novel receptor for Ox-LDL-designated lectin-like Ox-LDL receptor (LOX-1) in vascular endothelial cells. To examine ligand specificity of LOX-1, we established CHO cell line...
Lectin-like oxidized LDL receptor-1 (LOX-1) is a surface scavenger receptor for oxidized low-density lipoprotein (oxLDL). Several transcription factors have been reported to regulate LOX-1 expression. MicroRNAs are small noncoding RNAs that control gene expression, but there have been no reports of LOX-1 expression being regulated by microRNAs. Because the microRNA let-7g has been predicted to ...
Lysyl oxidase (LOX), a matrix cross-linking protein, is known to be selectively expressed and to enhance a fibrotic phenotype. A recent study of ours showed that LOX oxidizes the PDGF receptor-β (PDGFR-β), leading to amplified downstream signaling. Here, we examined the expression and functions of LOX in megakaryocytes (MKs), the platelet precursors. Cells committed to the MK lineage undergo mi...
Expression of the lysyl oxidase gene (LOX) was found to inhibit the transforming activity of the ras oncogene in NIH 3T3 fibroblasts and was hence named the ras recision gene (rrg). Lysyl oxidase (LOX) is synthesized and secreted as a 50-kDa inactive proenzyme (Pro-LOX), which is processed by proteolytic cleavage to a functional 32-kDa enzyme and an 18-kDa propeptide (LOX-PP). Recently, the ras...
One of the main criteria for salt tolerance is cell membrane stability under stress. Reactive oxygen species (ROS), activity of lipoxygenase (Lox) and lipid peroxidation are considered to be destructive to cell membrane under salt stress. In this study, the effects of 0, 75 and 150 mM NaCI, over a period of 14 days on the activity of lipoxygenease, the amount of hydrogen peroxide (H2O2) and mal...
Lysyl oxidase (LOX) is an extracellular matrix-remodeling enzyme that plays important roles in tumor development and progression. To evaluate the prognostic value of LOX levels in primary nasopharyngeal carcinoma, we performed an immunohistochemical analysis using 233 tissue biopsy specimens from as many patients. We found that the extent of immunohistochemical LOX staining correlated inversely...
15-Lipoxygenase-1 (15-LOX-1) has been proposed to be involved in various physiological and pathophysiological activities such as inflammation, atherosclerosis, cell maturation, and tumorigenesis. Asthma and chronic obstructive pulmonary disease are associated with increased expression of 15-LOX-1 in bronchial epithelial cells, but the potential functions of 15-LOX-1 in airway epithelial cells h...
IL-4Ralpha-dependent responses are essential for granuloma formation and host survival during acute schistosomiasis. Previously, we demonstrated that mice deficient for macrophage-specific IL-4Ralpha (LysM(cre)Il4ra(-/lox)) developed increased hepatotoxicity and gut inflammation; whereas inflammation was restricted to the liver of mice lacking T cell-specific IL-4Ralpha expression (iLck(cre)Il4...
