[PMID: 38104866 DOI: 10.1016/j.jnutbio.2023.109549] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/31/2023] [Revised: 12/02/2023] [Accepted: 12/13/2023] [Indexed: 12/19/2023]
Abstract
Obesity is a known risk factor for breast cancer, the most common malignancy among women worldwide. We have previously described different effects of high-fat diets on mammary experimental carcinogenesis. In this work, we analyzed the animal growth data obtained in six experimental assays, in healthy and carcinogen-induced rats undergoing different dietary interventions. The animals were fed with three experimental diets administered at different periods of development: a control low-fat diet, and two isocaloric high-fat diets (rich in corn oil or in extravirgin olive oil -EVOO-). Weekly weight throughout the development of 818 animals have been compiled and reanalyzed using adjusted mathematical models. Molecular mechanisms have been investigated: ethanolamides in small intestine, neuropeptides controlling satiety in hypothalamus, and proteins controlling lipid metabolism in adipose and mammary tissues. The results indicated that the effect of diets depended on type of lipid, timing of intervention and health status. The high corn oil diet, but not the high EVOO diet, increased body weight and mass, especially if administered from weaning, in healthy animals and in those that received a moderate dose of carcinogen. The potential protective effect of EVOO on weight maintenance may be related to anorexigenic neuropeptides such as oxytocin and lipolysis/deposition balance in adipose tissue (increasing phospho-PKA, HSL, MGL and decreasing FAS). In animals with cancer, body weight gain was related to the severity of the disease. Taken together, our results suggest that EVOO has a beneficial effect on body weight maintenance in both health and cancer.

Abstract
The discovery of the endocannabinoidome (eCBome) is evolving gradually with yet to be elucidated functional lipid mediators and receptors. The diet modulates these bioactive lipids and the gut microbiome, both working in an entwined alliance. Mounting evidence suggests that, in different ways and with a certain specialisation, lipid signalling mediators such as N-acylethanolamines (NAEs), 2-monoacylglycerols (2-MAGs), and N-acyl-amino acids (NAAs), along with endocannabinoids (eCBs), can modulate physiological mechanisms underpinning appetite, food intake, macronutrient metabolism, pain sensation, blood pressure, mood, cognition, and immunity. This knowledge has been primarily utilised in pharmacology and medicine to develop many drugs targeting the fine and specific molecular pathways orchestrating eCB and eCBome activity. Conversely, the contribution of dietary NAEs, 2-MAGs and eCBs to the biological functions of these molecules has been little studied. In this review, we discuss the importance of (Wh) olistic (E)ndocannabinoidome-Microbiome-Axis Modulation through (N) utrition (WHEN), in the management of obesity and related disorders.

Effect of flaxseed oil supplementation on the erythrocyte membrane fatty acid composition and endocannabinoid system modulation in patients with coronary artery disease: a double-blind randomized controlled trial. GENES AND NUTRITION 2020; 15:9. [PMID: 32370762 PMCID: PMC7201600 DOI: 10.1186/s12263-020-00665-1] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 08/30/2019] [Accepted: 03/05/2020] [Indexed: 01/09/2023]
Abstract
Background The endocannabinoid system (ECS) overactivation, associated with increased inflammatory process, may act as a risk factor for coronary artery disease (CAD). Dietary fat may influence the ECS tone. The aim of the present study was to investigate the effect of flaxseed oil on the erythrocyte membrane fatty acid profile and ECS activity by the measurement of serum N-arachydonoil ethanolamine (AEA) and cannabinoid receptor type-1 (CB1), cannabinoid receptor type-2 (CB2), and fatty acid amide hydrolase (FAAH) mRNA expression. Methods This clinical trial was performed on 44 patients with CAD. The intervention group received 1.5% fat milk supplemented with flaxseed oil (containing 2.5 g α-linolenic acid or ALA), while the placebo group received 1.5% fat milk for 10 weeks. The fatty acid profile of erythrocyte membrane phospholipids was measured by gas chromatography. The AEA level was determined using an ELISA kit, and real-time PCR was performed to measure CB1, CB2, and FAAH mRNA expression pre- and post-intervention. Results Flaxseed oil supplementation resulted in a significant increase in the ALA content and a significant reduction in linoleic acid (LA) content of membrane phospholipids, compared to the placebo group (MD = − 0.35 and 2.89, respectively; P < 0.05). The within group analysis showed that flaxseed oil supplementation caused a significant reduction in both LA and arachidonic acid (MD = − 4.84 and − 4.03, respectively; P < 0.05) and an elevation in the ALA (MD = 0.37, P < 0.001) content of membrane phospholipids compared with the baseline. In the intervention group, a marked reduction was observed in the serum AEA level after 10 weeks of intervention, compared with the placebo group (MD = 0.64, P = 0.016). Changes in CB2 mRNA expression in the flaxseed oil group were significant (fold change = 1.30, P = 0.003), compared with the placebo group. Conclusion Flaxseed oil supplementation could attenuate the ECS tone by decreasing the AEA level and increasing CB2 mRNA expression. Therefore, flaxseed oil may be considered a promising agent with cardioprotective properties.

Endocannabinoid system and cardiometabolic risk factors: A comprehensive systematic review insight into the mechanistic effects of omega-3 fatty acids. Life Sci 2020; 250:117556. [PMID: 32184122 DOI: 10.1016/j.lfs.2020.117556] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/11/2020] [Revised: 02/26/2020] [Accepted: 03/13/2020] [Indexed: 12/21/2022]
Abstract
Increased levels of endocannabinoids, 2-arachidonoylglycerol (2-AG) and arachidonoyl ethanolamide (AEA) have a pathophysiological role in the setting of cardiometabolic diseases. This systematic review was carried out to appraise the effect of omega-3 on cardiometabolic risk factors by highlighting the mediating effect of endocannabinoids. SCOPUS, PubMed, Embase, Google Scholar and ProQuest databases were searched until January 2020. All published English-language animal studies and clinical trials that evaluated the effects of omega-3 on cardiometabolic diseases with a focus on endocannabinoids were included. Of 1407 studies, 16 animal studies and three clinical trials were included for analysis. Eleven animal studies and two human studies showed a marked reduction in 2-AG and AEA levels following intake of omega-3 which correlated with decreased adiposity, weight gain and improved glucose homeostasis. Moreover, endocannabinoids were elevated in three studies that replaced omega-3 with omega-6. Omega-3 showed anti-inflammatory properties due to reduced levels of inflammatory cytokines, regulation of T-cells function and increased levels of eicosapentaenoyl ethanolamide, docosahexaenoyl ethanolamide and oxylipins; however, a limited number of studies examined a correlation between inflammatory cytokines and endocannabinoids following omega-3 administration. In conclusion, omega-3 modulates endocannabinoid tone, which subsequently attenuates inflammation and cardiometabolic risk factors. However, further randomized clinical trials are needed before any recommendations are made to target the ECS using omega-3 as an alternative therapy to drugs for cardiometabolic disease improvement.

Sihag J, Jones PJH. Dietary fatty acid profile influences circulating and tissue fatty acid ethanolamide concentrations in a tissue-specific manner in male Syrian hamsters. Biochim Biophys Acta Mol Cell Biol Lipids 2019; 1864:1563-1579. [PMID: 31301433 DOI: 10.1016/j.bbalip.2019.07.002] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/14/2019] [Revised: 07/04/2019] [Accepted: 07/07/2019] [Indexed: 12/20/2022]
Abstract
BACKGROUND The discovery of N‑acylethanolamines (NAEs) has prompted an increase in research aimed at understanding their biological roles including regulation of appetite and energy metabolism. However, a knowledge gap remains to understand the effect of dietary components on NAE levels, in particular, heterogeneity in dietary fatty acid (DFA) profile, on NAE levels across various organs. OBJECTIVE To identify and elucidate the impact of diet on NAE levels in seven different tissues/organs of male hamsters, with the hypothesis that DFA will act as precursors for NAE synthesis in golden Syrian male hamsters. METHOD A two-month feeding trial was performed, wherein hamsters were fed various dietary oil blends with different composition of 18-C fatty acid (FA). RESULTS DFA directly influences tissue FA and NAE levels. After C18:1n9-enriched dietary treatments, marked increases were observed in duodenal C18:1n9 and oleoylethanolamide (OEA) concentrations. Among all tissues; adipose tissue brown, adipose tissue white, brain, heart, intestine-duodenum, intestine-jejunum, and liver, a negative correlation was observed between gut-brain OEA concentrations and body weight. CONCLUSION DFA composition influences FA and NAE levels across all tissues, leading to significant shifts in intestinal-brain OEA concentrations. The endogenously synthesized increased OEA levels in these tissues enable the gut-brain-interrelationship. Henceforth, we summarize that the brain transmits anorexic properties mediated via neuronal signalling, which may contribute to the maintenance of healthy body weight. Thus, the benefits of OEA can be enhanced by the inclusion of C18:1n9-enriched diets, pointing to the possible nutritional use of this naturally occurring bioactive lipid-amide in the management of obesity.

Immunomodulatory effect of oleoylethanolamide in dendritic cells via TRPV1/AMPK activation. J Cell Physiol 2019; 234:18392-18407. [PMID: 30895621 DOI: 10.1002/jcp.28474] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/13/2018] [Revised: 02/15/2019] [Accepted: 02/19/2019] [Indexed: 12/26/2022]
Abstract
Oleoylethanolamide (OEA) is an endogenous lipid mediator involved in the control of feeding, body weight, and energy metabolism. However, whether OEA modulates maturation of dendritic cells (DCs) has never been addressed. Hence, we evaluated the effect of OEA on DCs maturation in bone marrow-derived DCs (BMDCs) in four aspects: (a) Cell surface markers were determined using flow cytometric analysis; (b) cell mobile ability was testified with the transwell assay; (c) stimulation of T cells proliferation was performed in a coculture system; and (d) cytokine production was measured using polymerase chain reaction (PCR). The result showed that, in mature BMDCs induced by lipopolysaccharides (LPS), the OEA treatment decreased expressions of cell surface markers, reduced cell migration, diminished the proliferation of cocultured T cells, and regulated cytokine production of BMDCs, indicating the modulatory effect of OEA on DCs maturation. Furthermore, to explore the underlying mechanism of the immunomodulatory effect of OEA, we used antagonists of transient receptor potential vanilloid-1 (TRPV1) and AMP-activated protein kinase (AMPK), determined the protein expressions of TRPV1/AMPK and Toll-like receptor 4 (TLR4)/nuclear factor-kappa B (NF-κB) using western blot, and measured the intracellular calcium concentration using calcium imaging. The result illustrated that OEA downregulated TLR4/NF-κB, the classical pathway leading to DCs maturation induced by LPS, through the activation of TRPV1 and AMPK. Collectively, the present study suggests that OEA suppresses DCs maturation through the activation of TRPV1/AMPK. These findings increase our understanding of this endogenous lipid OEA.
