AI Article Synopsis

  • FABP7 is a protein found in the brain that may help transport cannabinoids like THC, but its role in the endocannabinoid system is not fully understood.
  • In a study using mice lacking FABP7, researchers measured THC and its metabolite 11-OH-THC levels after THC inhalation, finding that females with FABP7 deletion had lower levels of 11-OH-THC compared to those with the protein.
  • The study also revealed that FABP7 influences endocannabinoid levels, showing females with FABP7 deletion had decreased levels of anandamide and increased levels of 2-AG, indicating a sex-specific role in THC metabolism and endocannabinoid regulation.

Article Abstract

Fatty acid binding protein 7 (FABP7) is present in the brain, but its interaction with the endocannabinoid system and phytocannabinoids is still not well understood. FABP7 has been proposed as a shuttle protein for trafficking endogenous cannabinoids, as well as an intracellular carrier of THC. In a mouse model of FABP7 global deletion, we used ultra-high performance liquid chromatography- tandem mass spectrometry (UPLC-MS/MS) to measure brain levels of Δ9 tetrahydrocannabinol (THC) as well as its primary metabolite, 11-hydroxy-THC (11-OH-THC), in male and female mice after acute inhalation of THC, compared to wild-type controls. We also measured brain levels of endogenous cannabinoids anandamide (AEA) and 2-arachidonoylglycerol (2-AG) both at baseline and after acute THC inhalation. We found that in females, brain concentrations of 11-OH-THC were significantly reduced in FABP7-/- mice compared to FABP7+/+. Additionally, FABP7-/- females had significantly reduced AEA levels and significantly increased 2-AG levels in brain tissue compared to FABP7+/+. Vaporized THC administration had trending, but not significant, impacts on endocannabinoid concentrations in both males and females. Our findings suggest a sex-specific role of FABP7 in the metabolism of THC as well as the regulation of endocannabinoid levels in the brain.

Purpose Of Review: This narrative review explores the role of Medical Nutritional Therapy (MNT) in managing Metabolic-Associated Steatotic Liver Disease (MASLD), previously known as nonalcoholic fatty liver disease. It aims to examine the effectiveness of specific nutritional strategies in preventing and treating this obesity-linked liver disease.

Recent Findings: Emerging evidence underscores the benefits of the Mediterranean diet, low-carbohydrate diets, and intermittent fasting in reducing liver fat, improving insulin sensitivity, and mitigating inflammation.

Evaluating the Real-World Safety of Icosapent Ethyl Versus Omega-3 Polyunsaturated Fatty Acid in Nationwide US Veterans Cohort: Examining Atrial Fibrillation and Bleeding Endpoints.

Clin Drug Investig

January 2025

Department of Medicine, Biostatistics, Epidemiology, and Informatics, University of Pennsylvania, Perelman School of Medicine, 423 Guardian Drive, Philadelphia, PA, 19104, USA.

Purpose: The REDUCE-IT randomized trial demonstrated a cardiovascular benefit of icosapent ethyl (IPE) but also raised potential safety signals for atrial fibrillation (AF) and serious bleeding. We aimed to evaluate the real-world safety of IPE versus mixed omega-3 polyunsaturated fatty acid (OM-3) formulations.

Methods: This retrospective active comparator new-user cohort study compared rates of new-onset AF and major bleeding (MB) among adult new users of IPE versus OM-3 in 2020-2024 US Veterans Affairs data.

Background: Growth differentiation factor (GDF)-15 is a pleiotropic cytokine that is associated with appetite-suppressing effects and weight loss in patients with malignancy.

Objectives: This study aims to investigate the relationships between GDF-15 levels, anorexia, cachexia, and clinical outcomes in patients with advanced heart failure with reduced ejection fraction (HFrEF).

Methods: In this observational, retrospective analysis, a total of 344 patients with advanced HFrEF (age 58 ± 10 years, 85% male, 67% NYHA functional class III), underwent clinical and echocardiographic examination, body composition evaluation by skinfolds and dual-energy x-ray absorptiometry, circulating metabolite assessment, Minnesota Living with Heart Failure Questionnaire, and right heart catheterization.

Non-communicable diseases (NCD) are associated with inflammation and oxidative stress which is further associated with omega-6 (ω6) and omega-3 (ω3) fatty acid (FA) imbalance favoring ω6 FA. By improving ω3 FA consumption, this imbalance can be altered to control NCD. Previously we have reported blends of flaxseed oil (FSO, ω3 FA) with palm olein (PO) or coconut oil (CO) were thermo-oxidatively stable with good storage stability and could improve ω6:ω3 ratio in cell lines.

Aim: This study aimed to explore the possible bidirectional interrelations between fructose-induced metabolic syndrome (MS) and apical periodontitis (AP).

Methodology: Twenty-eight male Wistar rats were distributed into four groups (n = 7, per group): Control (C), AP, Fructose Consumption (FRUT) and Fructose Consumption and AP (FRUT+AP). The rats in groups C and AP received filtered water, while those in groups FRUT and FRUT+AP received a 20% fructose solution mixed with water to induce MS.
