BACKGROUND Nonsteroidal anti-inflammatory drugs (NSAIDs) appear to act via induction of apoptosis-programmed cell death-as potential colorectal cancer chemopreventive agents. NSAIDs can alter the production of different metabolites of polyunsaturated fatty acids (linoleic and arachidonic acids) through effects on lipoxygenases (LOXs) and cyclooxygenases. 15-LOX-1 is the main enzyme for metaboli...
The lectin-like, oxidized low-density lipoprotein (ox-LDL) receptor-1 (LOX-1)/ox-LDL system contributes to atherosclerosis and may be involved in cartilage degeneration. The purpose of this study was to determine whether the LOX-1/ox-LDL system contributes to age-related osteoarthritis (OA) in vivo, using LOX-1 knockout (LOX-1 KO) mice. Knee cartilage from 6, 12, and 18-month old (n = 10/group)...
15-Lipoxygenase-1 (15-LOX-1) oxidizes polyunsaturated fatty acids to a rich spectrum of biologically active metabolites and is implicated in physiological membrane remodelling, inflammation and apoptosis. Its deregulation is involved in the pathogenesis of diverse cancer and immune diseases. Recent experimental evidence reveals that dynamic histone methylation/demethylation mediated by histone ...
تغذیه گیاهخواران موجب فعال شدن سیستم دفاع مستقیم و غیرمستقیم در گیاه میشود. بهمنظور بررسی نقش تعدادی از ژنهای مؤثر در دفاع مستقیم و یا غیرمستقیم لوبیا در برابر کنه تارتن دولکهای، میزان بیان این ژنها در تعدادی از ژنوتیپهای حساس (ژنوتیپ اختر) و مقاوم (ناز و ks41128) لوبیا به کنه دولکهای، قبل و بعد از آلودگی به کنه دولکهای بوسیله qrt-pcrمقایسه شد. سپس بهمنظور تأیید نتایج آزمایش qrt-pcr، ...
INTRODUCTION Lectin-like oxidized low-density lipoprotein receptor-1 (LOX-1), the major endothelial receptor for oxidized low-density lipoprotein, is also involved in leukocyte recruitment. Systemic leukocyte activation in sepsis represents a crucial factor in the impairment of the microcirculation of different tissues, causing multiple organ failure and subsequently death. The aim of our exper...
PURPOSE 15-Lipoxygenase-1 (15-LOX-1) plays an important role in regulating angiogenesis, but the mechanism to date is controversial, even contradictory. The goal of our study was to investigate whether 15-LOX-1 plays a role in inhibiting retinal neovascularization (RNV) in a mouse model of oxygen-induced retinopathy (OIR) and the underlying mechanism. METHODS Experiments were performed using ...
The lysyl oxidase (LOX) gene reverted Ras transformation of NIH 3T3 fibroblasts and tumor formation by gastric cancer cells, which frequently carry mutant RAS genes. The secreted lysyl oxidase proenzyme is processed to a propeptide (LOX-PP) and a functional enzyme (LOX). Unexpectedly, the tumor suppressor activity mapped to the LOX-PP domain, which inhibited tumor formation and the invasive phe...
Results from in vitro studies suggest that selected fatty acids, and especially linoleic acid (LA), can elicit endothelial dysfunction (ED). Because LA is increased in all LDL subfractions in patients with type 2 diabetes, this alteration may contribute to ED associated with diabetes. Lectin-like oxidized LDL receptor-1 (LOX-1) is the major endothelial receptor for oxidized LDL (oxLDL), and upt...
nitric oxide (no) is a highly reactive signaling molecule and plays a variety of physiological roles in plants. the research on the application of no to postharvest preservation of flowers and fruits shows great promise in recent years. however, the physiological mechanism of exogenous no to affect cut flowers is not very clear, and no donor treatment protected plants from damage by increasing ...
Lipoxygenases (LOXs) are non-heme iron containing dioxygenases involved in the oxygenation of polyunsaturated fatty acids (PUFAs) such as arachidonic acid (AA). Depending on the position of insertion of oxygen, LOXs are classified into 5-, 8-, 9-, 12- and 15-LOX. Among these, 5-LOX is the most predominant isoform associated with the formation of 5-hydroperoxyeicosatetraenoic acid (5- HpETE), th...
