EPA/DHA but Not ALA Reduces Visceral Adiposity and Adipocyte Size in High Fat Diet-Induced Obese Delta-6 Desaturase Knockout Mice.

The objective of this omega-3 feeding study was to elucidate the independent effects of α-linolenic acid (ALA) versus eicosapentaenoic (EPA)/docosahexaenoic acid (DHA) on visceral adiposity and inflammatory signaling in diet-induced obese delta-6 desaturase (Fads2) knockout (KO) mice. Male wildtype (WT) and Fads2 KO mice were fed a high-fat diet (45% kcal from fat) containing either lard (no omega-3s), flaxseed (ALA), or menhaden (EPA/DHA) for 21 weeks. Epididymal white adipose tissue (eWAT) was analyzed for changes in tissue weight, adipocyte size, triacylglycerol (TAG) and fatty acid content, and inflammatory markers.

α -lipoic acid supplementation reduces oxidative stress and inflammation in red skeletal muscle of insulin-resistant rats.

α -lipoic acid (ALA) is an eight-carbon saturated fatty acid with strong antioxidant activity. Despite previous reports of ALA's protective properties in treating cardiovascular and metabolic diseases (including insulin resistance and diabetes), little is known about the compound's effects on skeletal muscle metabolism. In particular, the effect of ALA on glycooxidative and nitrosative damage in red muscles during insulin resistance is unknown.

Cytotoxicity, Proapoptotic Activity and Drug-like Potential of Quercetin and Kaempferol in Glioblastoma Cells: Preclinical Insights.

Despite the increasing understanding of the pathogenesis of glioblastoma (GBM), treatment options for this tumor remain limited. Recently, the therapeutic potential of natural compounds has attracted great interest. Thus, dietary flavonoids quercetin (QCT) and kaempferol (KMF) were investigated as potential cytostatic agents in GBM.

Altered Cytokine Secretory Fingerprint of the Adipocytes Derived from Stem Cells of Morbidly Obese Patients-A Preliminary Study.

Adipose-derived mesenchymal stem cells (ADMSCs) are progenitor cells that shape the tissue's biological properties. To examine the adipocytes differentiated from the ADMSCs of lean and obese individuals with/without a metabolic syndrome (MetSx) cytokine secretory profile, as to date, little is known on this topic. Interleukin, chemokine and growth factor levels in the culture medium were determined using the Human Cytokine kit.

Cannabigerol-A useful agent restoring the muscular phospholipids milieu in obese and insulin-resistant Wistar rats?

Numerous strategies have been proposed to minimize obesity-associated health effects, among which phytocannabinoids appear to be effective and safe compounds. In particular, cannabigerol (CBG) emerges as a potent modulator of the composition of membrane phospholipids (PLs), which plays a critical role in the development of insulin resistance. Therefore, here we consider the role of CBG treatment on the composition of PLs fraction with particular emphasis on phospholipid subclasses (e.

Hepatic-Metabolic Activity of α-Lipoic Acid-Its Influence on Sphingolipid Metabolism and PI3K/Akt/mTOR Pathway in a Rat Model of Metabolic Dysfunction-Associated Steatotic Liver Disease.

Excessive lipid deposition affects hepatic homeostasis and contributes to the development of insulin resistance as a crucial factor for the deterioration of simple steatosis to steatohepatitis. So, it is essential to search for an effective agent for a new therapy for hepatic steatosis development before it progresses to the more advanced stages. Our study aimed to evaluate the potential protective effect of α-lipoic acid (α-LA) administration on the intrahepatic metabolism of sphingolipid and insulin signaling transduction in rats with metabolic dysfunction-associated steatotic liver disease (MASLD).

Adipose tissue place of origin and obesity influence sphingolipid signaling pathway in the adipocytes differentiated from ADMSCs isolated from morbidly obese women.

Adipose derived mesenchymal stem cells (ADMSCs) are a component of adipose tissue that in recent years has gained on importance. The progenitor cells serve as an essentially unlimited source of new adipocytes and therefore are considered to be an important determinant of the tissue's physiology. In this paper we investigated mature adipocytes differentiated from ADMSCs obtained from subcutaneous/visceral fat of patients with different metabolic status (lean, obese without and with metabolic syndrome).

Anti-inflammatory effects of cannabidiol in early stages of neuroinflammation induced by high-fat diet in cerebral cortex of rats.

High-fat diet (HFD) contributes to neuroinflammation forming, hence it is crucial to find safe and effective substances that are able to counteract its progress. The anti-inflammatory properties of phytocannabinoids acquired from the Cannabis plant have been widely acknowledged. We evaluated the effects of cannabidiol (CBD) treatment on induced by applying HFD early stages of neuroinflammation in Wistar rat cerebral cortex.

An Overview of Growth Factors as the Potential Link between Psoriasis and Metabolic Syndrome.

Psoriasis is a chronic, complex, and immunologically mediated systemic disease that not only affects the skin, but also the joints and nails. It may coexist with various other disorders, such as depression, psoriatic arthritis, cardiovascular diseases, diabetes mellitus, and metabolic syndrome. In particular, the potential link between psoriasis and metabolic syndrome is an issue worthy of attention.

Crosstalk between Serum and Skin Sphingolipids in Psoriasis.

Psoriasis is a chronic, complex, immunological disorder, which may lead to many different systemic complications. Sphingolipids, including ceramide, are bioactive lipids, which take part in the regulation of immune reactions, cell growth, and apoptosis. Twenty psoriatic patients and twenty-eight control subjects were included in the study.

Concentration-Dependent Attenuation of Pro-Fibrotic Responses after Cannabigerol Exposure in Primary Rat Hepatocytes Cultured in Palmitate and Fructose Media.

Hepatic fibrosis is a consequence of liver injuries, in which the overproduction and progressive accumulation of extracellular matrix (ECM) components with the simultaneous failure of matrix turnover mechanisms are observed. The aim of this study was to investigate the concentration-dependent influence of cannabigerol (CBG, component) on ECM composition with respect to transforming growth factor beta 1 (TGF-β1) changes in primary hepatocytes with fibrotic changes induced by palmitate and fructose media. Cells were isolated from male Wistar rats' livers in accordance with the two-step collagenase perfusion technique.

RabGAP AS160/TBC1D4 deficiency increases long-chain fatty acid transport but has little additional effect on obesity and metabolic syndrome in ADMSCs-derived adipocytes of morbidly obese women.

The Akt substrate of 160 kDa (AS160), also known as TBC1 domain family member 4 (TBC1D4), represents a crucial regulator of insulin-stimulated glucose uptake in skeletal muscle and adipose tissue. Recent evidence suggests that AS160/TBC1D4 may also control the cellular entry of long-chain fatty acids (LCFAs), resulting in changes to the lipid profile of muscles and fat cells in lean subjects. However, there are virtually no data on AS160/TBC1D4 expression and its modulatory role in lipid metabolism in the adipocytes from morbidly obese individuals of different metabolic status.
