The complexities of cell function in the central nervous system are sustained by intra- and intercellular signaling networks driven by synaptic activity, neurotrophins, gene programs and other factors. The molecular organization and functional contribution of cellular membranes are pivotal in the myriad of molecular circuitries of the CNS. Docosahexaenoic acid, an omega-3 fatty acid, is concentrated and avidly retained in membrane phospholipids of the nervous system, notably in photoreceptors and synapses. DHA is implicated in brain and retina function, aging, and neurological and psychiatric/behavioral illnesses. The discovery of neuroprotectin D1, the first docosanoid (a bioactive derivative of DHA), is allowing scientists to address fundamental questions concerning the biology of omega-3 fatty acids and their significance to brain function and the mechanisms of action in disease models such as stroke, epilepsy and neurodegeneration. The name "neuroprotectin D1" was suggested based on the ...

Protectin D1 also known as neuroprotectin D1 (when it acts in the nervous system) and abbreviated most commonly as PD1 or NPD1 is a member of the class of specialized proresolving mediators. Like other members of this class of polyunsaturated fatty acid metabolites, it possesses strong anti-inflammatory, anti-apoptotic and neuroprotective activity. PD1 is an aliphatic acyclic alkene 22 carbons in length with two hydroxyl groups at the 10 and 17 carbon positions and one carboxylic acid group at the one carbon position. Specifically, PD1 is an endogenous stereoselective lipid mediator classified as an autocoid protectin. Autacoids are enzymatically derived chemical mediators with distinct biological activities and molecular structures. Protectins are signaling molecules that are produced enzymatically from unsaturated fatty acids. Their molecular structure is characterized by the presence of a conjugated system of double bonds. PD1, like other protectins, is produced by the oxygenation of the ω-3 ...
OBJECTIVE To hypothesize that higher intake of docosahexaenoic acid, an n-3 long chain polyunsaturated fatty acid, would increase duration of gestation and birth weight in US women. METHODS This was a randomized, double-blind, controlled, clinical trial. Subjects were enrolled in an ambulatory clinic where they received prenatal care. This was a population-based sample. Most subjects received government assistance for medical care and most were black (73%). Subjects were enrolled between the 24th and 28th week of pregnancy and consumed docosahexaenoic acid (33 or 133 mg) from eggs until parturition. Gestational age and birth weight were the main study outcomes. Infant length and head circumference, preterm birth, and low birth weight were secondary outcomes. RESULTS Eighty-three percent of subjects completed the study (291 of 350 enrolled). No subject was discontinued for an adverse event. After controlling for important predefined risk factors and confounding variables, gestation increased by 6.0 +

Effects of docosahexaenoic acid on large-conductance Ca2+-activated K+ channels and voltage-dependent K+ channels in rat coronary artery smooth muscle cells.: D
By a News Reporter-Staff News Editor at VerticalNews Science -- DURHAM, N.C. - Physicians and patients who are wary of addiction to pain medication and opioids may soon have a healthier and more natural alternative. A Duke University study revealed that a derivative of DHA (docosahexaenoic acid), a main ingredient of over-the-counter fish oil supplements, can sooth and prevent neuropathic pain caused by injuries to the sensory system. The results appear online in the Annals of Neurology. The research focused on a compound called neuroprotectin D1=protectin D1 (NPD1=PD1), a bioactive lipid produced by cells in response to external stimuli. NPD1=PD1 is present in human white blood cells, and was first identified based on its ability to resolve abdominal and brain inflammation. "These compounds are derived from omega-3 fatty acids found in fish oil, but are 1,000 times more potent than their precursors in reducing inflammation," said Ru-Rong Ji, professor of anesthesiology and neurobiology at Duke ...
Some evidence shows that fetal development may be a critical for the development of allergies and asthma later in life, and that DHA may play a key role in the development of the immune system. This study aimed to investigate the effects of DHA supplementation during this time period on the incidence of allergies and asthma up to six years of age. Women in the KUDOS cohort were given 600 mg of DHA or a placebo during their second and third trimesters of pregnancy, and their offspring were followed up to six years of age. Two-hundred thirty infants were included. Their medical records were collected until six years of age or until their records could no longer be acquired if the infant dropped out before six years of age. All records were coded and allergic diagnoses were examined for this study. These diagnoses were grouped into three categories, skin allergies, wheeze/asthma, and other allergies. Associations and relative risks were calculated for each type of allergy diagnosis and no ...
Dendritic cells (DC) are professional antigen presenting cells which link innate and adaptive immunity through recognition and processing of pathogens, migration to secondary lymph nodes, presentation of antigens to naïve T cells and contribution to T cell proliferation and differentiation into various classes of effector T cells. N-3 fatty acids including docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA) were reported to have protective anti-inflammatory effects in clinical studies and animal models of colitis, sepsis, and stroke. However, the mechanisms involved in the anti-inflammatory function of EPA and DHA are not elucidated. Recent studies, including our own, investigated the effect of n-3 fatty acids on dendritic cells, and reported that DHA reduced the capacity of human monocyte-derived DC (hMo-DC) and of murine bone marrow derived conventional DC (BMDC) to produce IL-12 and to stimulate CD4+ T cell proliferation. The objectives of this thesis were to provide a comprehensive ...
Uncoupling protein 3 (UCP3) is a mitochondrial membrane transporter that is expressed mainly in skeletal muscle where it plays an important role in energy expenditure and fat oxidation. In this study, we investigated the effects of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) on UCP3 gene expression in C2C12 muscle cells. EPA and DHA up-regulated UCP3 mRNA level in a dose-dependent manner and similarly increased UCP3 promoter activity in C2C12 muscle cells. To determine whether AMP-activated protein kinase (AMPK) signaling may also directly regulate UCP3 expression, 5′-amino-4-imidazolecarboxamide-ribonucleoside (AICAR), an AMP analog that activates AMPK, was treated in C2C12 muscle cells. AICAR showed additive effects with EPA or DHA on the UCP3 promoter activation. These results indicate that EPA and DHA directly regulate the gene expression of UCP3, potentially through AMPK-mediated pathway in C2C12 muscle cells.
Abstract: : Purpose: In a placebo-controlled trial to elevate blood-DHA levels in patients with XLRP, the goal was to assess the potential benefit of supplementation in altering disease progression. However, DHA (22:6w3) is a highly unsaturated long-chain fatty acid and is considered a target molecule for free-radical oxidative damage. Thus, nutritional provision of DHA in a treatment protocol for XLRP may be contra-indicated. Here, non-ocular adverse events as well as antioxidant and blood lipid profiles were assessed at the conclusion of a 4-year supplementation trial. Methods: Patients (n=44) were enrolled in a randomized, double-blind, clinical trial and provided either DHA (400mg/day) or a corn/soy oil placebo. Blood samples were collected every six months for the duration of the trial. Biological safety analysis included blood lipid fatty acid determination, plasma vitamin A & E levels, platelet aggregation, and plasma antioxidant capacity. Results: DHA supplementation elevated blood lipid ...

Facebook Dr. Anil Home page AutismItsGutStupid Wall Street Journal Best Seller Dr. Ms Seven-X Plan for Digestive Health Polyunsaturated fatty acids like arachidonic acid (ARA) and docosahexaenoic acid (DHA) are believed to play a critical role in growth and development of brain including the signal messaging system in the brain. Docosahexaenoic Acid supplementation is frequently used to treat kids with autism. Dr. Voigt and colleagues recently conducted a randomized placebo controlled trial in 48 kids. Half of them received 200 mg DHA every day while the rest received placebo. Clinical Global Impressions-Improvement (CGI-I) scales was used. At the end of 6 months, although the DHA group showed a 431% increase in DHA levels, the investigators found that DHA did not have beneficial impact on core behavior of autistic kids as compared to those on placebo. However, Voigt and colleagues conceded that the negative results may have been as a result...

Dietary balance of long-chain fatty acids may influence processes involving leukocyte-endothelial interactions, such as atherogenesis and inflammation, that involve increased endothelial expression of leukocyte adhesion molecules, or endothelial activation. We compared the ability of various saturated, monounsaturated, and polyunsaturated fatty acids to modulate endothelial activation. Consumption of the n-3 fatty acid docosahexaenoic acid (DHA; 22:6n-3) reduced endothelial expression of vascular cell adhesion molecule 1 (VCAM-1), E-selectin, intercellular adhesion molecule 1 (ICAM-1), interleukin 6 (IL-6), and IL-8 in response to IL-1, IL-4, tumor necrosis factor, or bacterial endotoxin, with a half-maximal inhibitory concentration (IC(50)) of 1-25 micromol, ie, in the range of nutritionally achievable plasma concentrations. The magnitude of this effect paralleled its incorporation into cellular phospholipids. DHA also reduced the adhesion of human monocytes and monocytic U937 cells to ...

Polyunsaturated phospholipids are known to be important with regard to the biological functions of essential fatty acids, for example, involving neural tissues such as the brain and retina. Here we have employed two complementary structural methods for the study of polyunsaturated bilayer lipids, viz. deuterium ((2)H) NMR spectroscopy and molecular dynamics (MD) computer simulations. Our research constitutes one of the first applications of all-atom MD simulations to polyunsaturated lipids containing docosahexaenoic acid (DHA; 22:6 cis-Delta(4,7,10,13,16,19)). Structural features of the highly unsaturated, mixed-chain phospholipid, 1-palmitoyl-2-docosahexaenoyl-sn-glycero-3-phosphocholine (PDPC), have been studied in the liquid-crystalline (L(alpha)) state and compared to the less unsaturated homolog, 1-palmitoyl-2-oleoyl-sn-glycero-3-phosphocholine (POPC). The (2)H NMR spectra of polyunsaturated bilayers are dramatically different from those of less unsaturated phospholipid bilayers. We show ...

Supplementation With Highly Purified Docosahexaenoic Acid Ethyl Ester Was Associated With Enhancement of Hepatic Fatty Acid Oxidation and Greater Apparent Absorption of Docosahexaenoic Acid in Rats
Organelle remodeling processes are evolutionarily conserved and involved in cell functions during development, aging, and cell death. Some endogenous and exogenous molecules can modulate these processes. Docosahexaenoic acid (DHA), an omega-3 polyunsaturated fatty acid, has mainly been considered as a modulator of plasma membrane fluidity in brain development and aging, while DHAs role in organelle remodeling in specific neural cell types at the ultrastructural level remains largely unexplored. DHA is notably incorporated into dynamic organelles named lipid bodies (LBs). We hypothesized that DHA could attenuate the inflammatory response in lipopolysaccharide (LPS)-activated microglia by remodeling LBs and altering their functional interplay with mitochondria and other associated organelles. We used electron microscopy to analyze at high spatial resolution organelle changes in N9 microglial cells exposed to the proinflammogen LPS, with or without DHA supplementation. Our results revealed that DHA

As is known to all, the intracellular Rhodamine123 concentrations in MDR cells were extremely lower than sensitive cells. Meanwhile, the molecular mechanism of MDR is not fully clarification. It is well known that formation of MDR is complicated process and involves multiple factors, including increased drug efflux, alteration the apoptotic response, and change of DNA damage repair capacity in drug resistance tumor cells [16]. Among these factors, the most important reason is the drug efflux resulting from enhancement of drug transporter activity. These transporters originated from ATP-binding cassette (ABC) transporters super family such as P-gp, MRP1, MRP2, BCRP and LRP [17]. Accumulated evidences have indicated that over expression of P-gp directly contributes to MDR, and blocking P-gp drug pump functions and suppressing its expression might enhance the effects of chemotherapeutic drugs on MDR cancer cells [18]. Giada has reported that they reverse MDR in colon cancer cells by inhibiting the ...
5-year-old children whose mothers received modest DHA supplementation for the first 4mos of breastfeeding performed better on a test of sustained attention.
A high intake of the omega-3 fatty acid docosahexaenoate [docosahexaenoic acid (DHA)] has been associated with systemic antiinflammatory effects and cardiovascular protection. Cyclooxygenase (COX)-2 is responsible for the overproduction of prostaglandins (PG) at inflammatory sites, and its expression is increased in atheroma. We studied the effects of DHA on COX-2 expression and activity in human saphenous vein endothelial cells challenged with proinflammatory stimuli. A ≥24-h exposure to DHA reduced COX-2 expression and activity induced by IL-1, without affecting COX-1 expression. DHA effect depended on the NF-κB-binding site in the COX-2 promoter. EMSAs confirmed that DHA attenuated NF-κB activation. Because MAPK, PKC, and NAD(P)H oxidase all participate in IL-1-mediated COX-2 expression, we also tested whether these enzymes were involved in DHA effects. Western blots showed that DHA blocked nuclear p65 NF-κB subunit translocation by decreasing cytokine-stimulated reactive oxygen species ...

Preliminary studies have shown a reduced risk of Alzheimers disease (AD) in people consuming increased amounts of fish in their diets. Many of the health benefits of fish are attributed to the abundance of omega 3 fatty acids. Docosahexaenoic Acid (DHA) is the most abundant omega 3 fatty acid in the brain. Data from several animal models supports the hypothesis that DHA may be an effective treatment for AD by means of anti-amyloid, antioxidant, and neuroprotectant mechanisms.. In this study, 400 individuals with mild to moderate AD will participate at approximately 53 study sites throughout the US for 18 months. Participants will be randomized so that 60% will receive approximately 2 grams of DHA, divided into 4 capsules, 2 capsules taken twice a day, while 40% receive an identical placebo.. Potential participants will go to their study site for a screening visit, where eligibility is determined, and if accepted, for a baseline visit where cognitive status, behavioral status, functional status, ...

Purpose: : In many retina neurodegenerative diseases, photoreceptors (PRs) progressively degenerate by apoptosis causing visual loss. We demonstrated that docosahexaenoic acid (DHA), the major polyunsaturated fatty acid in the retina, promotes the survival of rat retina PRs during early development in vitro and upon oxidative stress by activating the ERK/MAP kinase signaling pathway. We have now investigated upstream this pathway, to establish whether DHA acts indirectly, modifying membrane properties to induce the activation of tyrosine kinase receptors (TRK) or directly, acting as a ligand for retinoid X receptors (RXR), as has been shown in the brain. We have also evaluated whether DHA has to be released from membrane phospholipids to exert its protective effect. Methods: : We prepared pure retinal neuronal cultures, supplemented or not with DHA, and incubated for 6 days or treated at day 3 with oxidants paraquat (PQ) or H2O2. To investigate activation of TRK and RXR, prior to DHA addition we ...
Peroxisome proliferator-activated receptor β (PPARβ) and NaV1.5 voltage-gated sodium channels have independently been shown to regulate human breast cancer cell invasiveness. The n-3 polyunsaturated docosahexaenoic acid (DHA, 22:6n-3), a natural ligand of PPAR, is effective in increasing survival and chemotherapy efficacy in breast cancer patient with metastasis. DHA reduces breast cancer cell invasiveness and it also inhibits PPARβ expression. We have shown previously that NaV1.5 promotes MDA-MB-231 breast cancer cells invasiveness by potentiating the activity of Na(+)/H(+) exchanger type 1 (NHE-1), the major regulator of H(+) efflux in these cells. We report here that DHA inhibited NaV1.5 current and NHE-1 activity in human breast cancer cells, and in turn reduced NaV1.5-dependent cancer cell invasiveness. For the first time, we show that antagonizing PPARβ, or inhibiting its expression, reduced NaV1.5 mRNA and protein expression and NaV1.5 current, as well as NHE-1 activity and cell ...

If we can easily test our blood glucose and cholesterol levels, why cant we test the level of omega 3 fatty acids in our blood? Nothing - not cholesterol or even C-reactive protein levels - is better at predicting sudden cardiac death, which still causes about 60 percent of cardiac disease death in the United States, according to an analysis by Centers for Disease Control researchers.. For years this lack of an omega 3 blood test puzzled me. No more. It has finally arrived.. The HS-Omega-3 Index uses a standardized methodology to measure the percentage of eicosapentaenoic acid (EPA) plus docosahexaenoic acid (DHA) in red blood cells. It also measures the ratio of omega 3 to omega 6.. Some cold water fish like salmon, mackerel, herring, albacore tuna, and sardines have a lot of this healthy omega 3 fat. I follow the standard recommendation to eat one of these fish at least twice a week. I supplement my fish with krill oil capsules for even more omega 3.. Americans generally have low levels of ...
Obesity induces chronic inflammation and is an established risk and progression factor for triple-negative breast cancers, including basal-like (BL) and claudin-low (CL) subtypes. We tested the effects of dietary supplementation with ethyl esters of the marine-derived anti-inflammatory omega-3 fatty acids eicosapentaenoic and docosahexaenoic acid (EPA+DHA; Lovaza) on growth of murine BL and CL mammary tumors. Female ovariectomized C57BL/6 mice were fed a control diet or a diet-induced obesity (DIO) diet with or without EPA+DHA (0.025%, resulting in blood levels of EPA and DHA comparable with women taking Lovaza 4 g/d) for 6 weeks. All mice were then orthotopically injected with Wnt-1 cells (a BL tumor cell suspension derived from MMTV-Wnt-1 transgenic mouse mammary tumors) or M-Wnt cells (a CL tumor cell line cloned from the Wnt-1 tumor cell suspension). Mice were killed when tumors were 1 cm in diameter. EPA+DHA supplementation did not significantly affect Wnt-1 or M-Wnt mammary tumor growth in ...
You will have heard barely speak about the advantages of consuming omega three fish oils, however why precisely are they so necessary, and what do it is advisable learn about them? A Transient Introduction To Omega three The time period "omega 3" refers to a household of fat thats necessary for well being. These fat are discovered in several types, together with alpha-linolenic acid (ALA), eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA).

EPA and DHA consumption of between 2 g and four g per day had been discovered to assist keep optimum blood stress ranges, ...
Research supports the hypothesis that GPR18 is the abnormal cannabidiol receptor and N-arachidonoyl glycine, the endogenous lipid metabolite of anandamide, initiates directed microglial migration in the CNS through activation of GPR18,[10] though recent evidence demonstrates that NAGly was not shown to be a GPR18 agonist in rat sympathetic neurons.[11]. Resolvin D2 (RvD2), a member of the specialized proresolving mediators (SPM) class of polyunsaturated fatty acid metabolites, is an activating ligand for GPR18; RvD2 and its activation of GPR18 contribute to the resolution of inflammatory responses as well as inflammation-based and other diseases in animal models and are proposed to do so in humans.[12] Furthermore, RvD2 is a metabolite of the omega-3 fatty acid, docosahexaenoic acid (DHA); the metabolism of DHA to RvD2 and RvD2s activation of GPR18 is proposed to one among many other mechanisms for the anti-inflammatory and other beneficial effects attributed to omega-3 fatty acid-rich ...
Omega-3 fatty acids are considered essential fatty acids because humans must get them from food or supplementation; i.e., they cannot be made from other substances in the body. Essential omega-3 fatty acids from fish, EPA and DHA, are beneficial for the cardiovascular system. They support good circulation by maintaining healthy blood vessels, enhancing blood flow by optimizing vascular endothelial function, and maintaining already normal triglyceride and cholesterol levels.Omega-3 fatty acids EPA and DHA are also supportive of healthy brain function. EPA and DHA are important throughout adulthood, as well as during periods of increased brain growth that characterize prenatal and postnatal development. Dietary supplementation with DHA and EPA has proven beneficial for a number of the known higher mental functions.Super EPA (an EPA/DHA-containing fish oil supplement) has been one of Thorne Researchs best-selling products for over two decades because of its exceptional purity and quality.
