Residual risk, which cannot be prevented by statins alone, must be controlled for inhibiting the onset of coronary events. Omega-3 polyunsaturated fatty acids (PUFAs) play an important role in controlling residual risk. The Japan eicosapentaenoic acid (EPA) Lipid Intervention Study demonstrated the inhibitory effect of high-purity EPA preparations on the residual risk of cardiovascular events. Omega-3 PUFAs inhibit coronary artery disease (CAD) through various actions, including triglyceride-lowering action...

Taking fish oil supplements in the third trimester of pregnancy was associated with significantly less wheezing or asthma in the child at the age of 3-5 years, according to a randomized clinical trial by Bisgaard et al., NEJM 2017. However, the results of this study should be interpreted with caution. The primary end points were modified at a late stage in the study, and two primary end points, eczema in the first 3 years of life and allergic sensitization at 18 months of age, were demoted to secondary end points, and showed no significant effect of treatment...

The omega-3 fatty acid, alpha linolenic acid (ALA) found in plant-derived foods induces significant cardiovascular benefits when ingested. ALA may be cardioprotective during ischemia; however, the mechanism(s) responsible for this effect is unknown. Isolated adult rat cardiomyocytes were exposed to medium containing ALA for 24 h and then exposed to non-ischemic (control), simulated ischemia (ISCH), or simulated ischemia/reperfusion (IR) conditions. Cardiomyocyte phospholipids were extracted and analyzed by an HPLC/electrospray ionization tandem mass spectrometry system...

Mϕs of patients with Alzheimer's disease and mild cognitive impairment (MCI) are defective in amyloid-β1-42 (Aβ) phagocytosis and have low resistance to apoptosis by Aβ. ω-3 in vitro and in vivo and the ω-3 mediator, resolvin D1, in vitro increase Aβ phagocytosis by Mϕs of patients with MCI. We have investigated the unfolded protein response (UPR) to endoplasmic reticulum (ER) stress by Mϕs in a longitudinal study of fish-derived, ω-3-supplemented patients with MCI. Patients in the apolipoprotein E (ApoE)e3/e3 subgroup over time exhibited an increase of protein kinase RNA-like ER kinase (PERK) expression, Aβ phagocytosis, intermediate M1-M2 Mϕ type, and a Mini-Mental State Examination (MMSE) rate of change of +1...

High insulin levels in obese people are considered as a risk factor to induce breast carcinogenesis. And consumption of fish oils which mainly contain omega-3 fatty acids is associated with a reduced risk of breast cancer. However, whether omega-3 free fatty acids (FFAs) modulate insulin signaling pathway to prevent breast cancer is poorly understood. The current study tested the hypothesis that omega-3 FFAs attenuate insulin-induced breast cancer cell proliferation and regulate insulin signaling pathway. We show here that omega-3 FFAs attenuate MCF-7 cell proliferation and Akt and Erk1/2 phosphorylation levels stimulated by insulin...

A low Omega-3 Index (eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) in erythrocytes) is associated with cardiac, cerebral, and other health issues. Intake of EPA and DHA, but not of alpha-linolenic acid (ALA), increases the Omega-3 Index. We investigated bioavailability, safety, palatability and tolerability of EPA and DHA in a novel source: a variety of sausages. We screened 96 healthy volunteers, and recruited 44 with an Omega-3 Index <5%. Participants were randomly assigned to receive a variety of sausages enriched with approximately 250 mg EPA and DHA per 80 g (n = 22) daily for 8 weeks, or matching placebo sausages (n = 22)...

Breast cancer is a leading type of cancer in women and generally classified into three subtypes of ER(+) /PR(+) , HER2(+) and triple negative. Both omega-3 polyunsaturated fatty acids and vitamin D3 play positive role in the reduction of breast cancer incidence. However, whether combination of omega-3 polyunsaturated fatty acids and vitamin D3 has stronger protective effect on breast carcinogenesis still remains unknown. In this study, we show that the combination of ω-3 free fatty acids (ω-3 FFAs) and 1α, 25-dihydroxy-vitamin D3 (VD3 ) dramatically enhances cell apoptosis among three subtypes of breast cancer cell lines...

Microalgae have been studied as biofactories for almost four decades. Yet, even until today, many aspects of microalgae farming and processing are still considered exploratory because of the uniqueness of each microalgal species. Thus, it is important to develop the entire process of microalgae farming: from culturing to harvesting, and down to extracting the desired high-value products. Based on its rapid growth and high oil productivities, Nannochloropsis sp. is of particular interest to many industries for the production of high-value oil containing omega-3 fatty acids, specifically eicosapentaenoic acid (EPA), but also several other products...

Cancer is a major public health problem worldwide and is the second leading cause of death in the United States. Although cancer death rate has dropped by 23% since 1991, there are certain types of cancer for which death rates are still increasing such as, pancreatic cancer. There is an urgent need to find new therapies that could help improve this dreadful outcome. In this regard, the role of nutrition in health and disease has attracted much attention. Several dietary ingredients are involved in metabolic, physiological, and cellular signaling affecting tumor growth and progression...

Docosahexaenoic acid (DHA), an omega-3 essential fatty acid family member that is enriched in the nervous system, generates bioactive docosanoids that can counteract disruptions of cellular homeostasis. Docosanoids include neuroprotectin D1 (NPD1), which is decreased in the CA1 hippocampal area of patients with early-stage Alzheimers disease (AD). We summarize here how NPD1 elicits neuroprotection by up-regulating c-REL, a nuclear factor (NF)-kappaB subtype that, in turn, enhances expression of BIRC3 (baculoviral IAP repeat-containing protein 3, or cIAP2) in retinal cells...

Obesity and type 2 diabetes are increasing in rural and urban regions of South Asia including India. Pattern of fat deposition in abdomen, ectopic fat deposition (liver, pancreas) and also low lean mass are contributory to early-onset insulin resistance, dysmetabolic state and diabetes in Asian Indians. These metabolic perturbations are further exacerbated by changing lifestyle, diet urbanization, and mechanization. Important dietary imbalances include increasing use of oils containing high amount of trans fatty acids and saturated fats (partially hydrogenated vegetable oil, palmolein oil) use of deep frying method and reheating of oils for cooking, high intake of saturated fats, sugar and refined carbohydrates, low intake of protein, fiber and increasing intake of processed foods...

Omega 3 polyunsaturated fatty acids have been reported to confer beneficial health effects notably in the field of cardiovascular and inflammatory diseases. The current knowledge suggests a significant portion of the effects of omega 3 polyunsaturated fatty acids are mediated by their oxygenated metabolites. This review attempts to cover the current literature about the contribution of specific omega 3 oxygenated metabolites, namely omega 3 isoprostanoids, which are produced through free-radical mediated oxidation...

Cardiovascular disease (CVD) remains one of the major causes of death and disability worldwide. In addition to drug treatment, nutritional interventions or supplementations are becoming a health strategy for CVD prevention. Phytosterols (PhyS) are natural components that have been shown to reduce cholesterol levels; while poly-unsaturated fatty acids (PUFA), mainly omega-3 (ω3) fatty acids, have shown to reduce triglyceride levels. Here we aimed to investigate whether the proteins in the main lipoproteins (low density lipoproteins (LDL) and high density lipoproteins (HDL)) as well as proteins in the lipid free plasma fraction (LPDP) were regulated by the intake of PhyS-milk or ω3-milk, in overweight healthy volunteers by a proteomic based systems biology approach...
