Alzheimer's disease (AD) is a common neurodegenerative disorders, in which oxidative stress plays an important role. The present study investigated the effect of eicosapentaenoic acid-enriched phospholipids (EPA-enriched PL) from the sea cucumber Cucumaria frondosa on oxidative injury in PC12 cells induced by hydrogen peroxide (H2O2) and tert-butylhydroperoxide (t-BHP). We also studied the effe...

Omega-3 fatty acids are products of secondary metabolism, essential for growth and important for human health. Although there are numerous reports of bacterial production of omega-3 fatty acids, less information is available on the biotechnological production of these compounds from bacteria. The production of eicosapentaenoic acid (EPA, 20:5ω3) by a new species of marine bacteria Shewanella el...

Eicosapentaenoic acid (EPA) is an omega-3 polyunsaturated fatty acid that has anti-inflammatory and anticachectic actions. The aim of this work was to elucidate whether EPA administration is able to prevent an arthritis-induced decrease in body weight and muscle wasting in rats. Arthritis was induced by intradermal injection of Freund's adjuvant; 3 days later, nine rats received 1 g/kg EPA or c...

Eicosapentaenoic acid (EPA) is essential for normal cell growth, and may play an important role in inflammatory and autoimmune disorders including rheumatoid arthritis. We investigate that EPA could suppress the proliferation of fibroblast like synoviocytes in vitro. We treated synoviocytes with 1 to 50 microM EPA and measured cell viabilities by the modified MTT assay. We sorted the number of ...

BACKGROUND AND PURPOSE Recent studies reported the differential effect of docosahexaenoic (DHA) and eicosapentaenoic acids (EPA). We examined the differential association of DHA and EPA with carotid intima-media thickness (IMT) in Japanese individuals in Japan and in U.S. white individuals and explored whether DHA or EPA contributes to the difference in IMT between the two groups. METHODS A p...

BACKGROUND Fatty acid binding protein 2 (FABP2) and peroxisome proliferator-activated receptor α (PPARα) are involved in cellular uptake and metabolism of fatty acids. Polymorphism of FABP2 and PPARα may influence plasma levels of fatty acids in those who take supplemental eicosapentaenoic acid (EPA). The purpose of this study was to study the potential associations between the Ala54/Thr polymo...

INTRODUCTION Infections produce severe respiratory muscle weakness, which contributes to the development of respiratory failure. An effective, safe therapy to prevent respiratory muscle dysfunction in infected patients has not been defined. This study examined the effect of eicosapentaenoic acid (EPA), an immunomodulator that can be safely administered to patients, on diaphragm force generation...

Recent studies have shown that free fatty acids are associated with chronic inflammation, which may be involved in vascular injury. The intake of eicosapentaenoic acid (EPA) can decrease cardiovascular disease risks, but the protective mechanisms of EPA on endothelial cells remain unclear. In this study, primary human umbilical vein endothelial cells (HUVECs) treated with palmitic acid (PA) wer...

BACKGROUND Saturated fatty acids have been shown to cause insulin resistance and low-grade chronic inflammation, whereas unsaturated fatty acids suppress inflammation via G-protein coupled receptor 120 (GPR120) in macrophages. However, the anti-inflammatory effects of unsaturated fatty acids in adipocytes have yet to be elucidated. Hence, the aims of the present study were to evaluate the anti-...

In dystrophin-deficient fibers of mdx mice and in Duchenne muscular dystrophy, inflammation and increased production of tumor necrosis factor alpha (TNF-α) contribute to myonecrosis. We examined the effects of eicosapentaenoic acid (EPA) on dystrophic muscle degeneration. Mdx mice (14 days old) received EPA for 16 days. The sternomastoid, diaphragm and biceps brachii muscles were removed. Contr...
