Asperuloside Enhances Taste Perception and Prevents Weight Gain in High-Fat Fed Mice

2021

Asperuloside is an iridoid glycoside found in many medicinal plants that has produced promising anti-obesity results in animal models. In previous studies, three months of asperuloside administration reduced food intake, body weight, and adipose masses in rats consuming a high fat diet (HFD). However, the mechanisms by which asperuloside exerts its anti-obesity properties were not clarified. Here, we investigated homeostatic and nutrient-sensing mechanisms regulating food intake in mice consuming HFD. We confirmed the anti-obesity properties of asperuloside and, importantly, we identified some mechanisms that could be responsible for its therapeutic effect. Asperuloside reduced body weight …

Leptin and the OB-receptor as anti-obesity target: recent in silico advances in the comprehension of the protein-protein interaction and rational dru…

2014

The OB-receptor or leptin receptor (LR) is crucial for energy homeostasis and regulation of food uptake. Leptin is a 16 kDa hormone that is mainly secreted by fat cells into the bloodstream. Under normal circumstances, circulating leptin levels are proportionate to the fat body mass. Sensing of elevated leptin levels by the hypothalamic neuro-circuitry activates a negative feedback loop resulting in reduced food intake and increased energy expenditure. Decreased leptin concentrations lead to opposite effects. Therefore, rational design of leptin agonists/antagonists could be an appealing challenge in the battle against obesity. The Leptin/LR interactions have been studied in several works b…

Molecular dynamics, dynamic site mapping, and highthroughput virtual screening on leptin and the Ob receptor as anti-obesity target.

2014

Body weight control is a mechanism finely regulated by several hormonal, metabolic, and nervous pathways. The leptin receptor (Ob-R) is crucial for energy homeostasis and regulation of food uptake. Leptin is a 16 kDa hormone that is mainly secreted by fat cells into the bloodstream, and under normal circumstances, circulating levels are proportionate to the fat body mass. Sensing of elevated leptin levels by the hypothalamic neurocircutry activates a negative feedback loop resulting in reduced food intake and increased energy expenditure. Decreased concentrations lead to opposite effects. Therefore rational design of leptin agonists constitute an appealing challenge in the battle against ob…

Glucagon-like peptide-2 and mouse intestinal adaptation to a high-fat diet.

2013

Endogenous glucagon-like peptide-2 (GLP2) is a key mediator of refeeding-induced and resection-induced intestinal adaptive growth. This study investigated the potential role of GLP2 in mediating the mucosal responses to a chronic high-fat diet (HFD). In this view, the murine small intestine adaptive response to a HFD was analyzed and a possible involvement of endogenous GLP2 was verified using GLP2 (3–33) as GLP2 receptor (GLP2R) antagonist. In comparison with animals fed a standard diet, mice fed a HFD for 14 weeks exhibited an increase in crypt–villus mean height (duodenum, 27.5±3.0%; jejunum, 36.5±2.9%;P<0.01), in the cell number per villus (duodenum, 28.4±2.2%; jejunum, 32.0±2.9%;P&l…

The metabolic syndrome: Definition, diagnosis and management

2008

The metabolic syndrome (MetS) constitutes a major public health problem in the developed countries.(1) It is cited with different names, such as syndrome X, insulin resistance syndrome, Reaven's syndrome or CHAOS (Australia). MetS increases the cardiovascular risk, but with specific lifestyle changes and individualized drug treatment the development of serious vascular complications can be avoided. In the last years, MetS has become a prevalent clinical condition. Therefore, it is necessary to create a complete document on the diagnosis and clinical management of MetS to avoid the confusion that derives from the vast amount of scientific papers, different revisions and definitions of the sy…

Effects of malvidin, cyanidin and delphinidin on human adipose mesenchymal stem cell differentiation into adipocytes, chondrocytes and osteocytes.

2019

Abstract Background Anthocyanidins are plant phytochemicals found at high concentrations in berries, vegetables and flowers. Anthocyanidins have been extensively investigated due to their antioxidative, antidiabetic and anti-inflammatory effects. Few studies show that anthocyanidins decrease obesity and improve bone density. However, the effects of anthocyanidins on tissue regeneration have not been sufficiently clarified. Human mesenchymal stem cells (MSCs) are multipotent adult stem cells responsible for the regeneration of fat, bone and cartilage. Although MSCs are often used for screening of biologically active compounds, so far, the effect of anthocyanidins on MSC differentiation has n…

Risks Associated with the Use of Garcinia as a Nutritional Complement to Lose Weight

2021

Nowadays, obesity is one of the great nutritional problems facing public health. The prevalence of this pathology has increased in a worrying way over recent years, currently reaching epidemic proportions. In this context, nutritional supplements are presented as a therapeutic alternative to which more and more people are turning to. Nutritional supplements to lose weight based on the Garcinia plant, specifically on Garcinia cambogia, are commonly used. The active principle of this plant to which these properties have been attributed, is hydroxycitric acid (HCA). The aim of the present review is to gather reported data concerning the effectiveness of nutritional supplements based on Garcini…

Adipokines and Lipoproteins: Modulation by Antihyperglycemic and Hypolipidemic Agents

2014

Abstract Adipose tissue is an endocrine organ that secretes a number of hormones and metabolically active substances that impact energy metabolism and insulin sensitivity. These inflammatory markers are collectively referred to as adipocytokines, or adipokines. Adipose tissue's functional capacity and metabolic activity vary among individuals, thus partly explaining the incomplete overlap between obesity and the metabolic syndrome. The functional failure of adipose tissues results in changed energy delivery and impaired glucose consumption, triggering self-regulatory mechanisms to maintain homeostasis. Antihyperglycemic, hypolipidemic, antiobesity, and angiotensin II receptor blocker drugs …

Obesity and cardiovascular risk: the new public health problem of worldwide proportions

2004

Obesity could be considered a new global health epidemic above all others, especially when it is characterized by central fat distribution. This is illustrated by dramatic provisional data, indicating a continuous increase in the trend of overweight and obese individuals in several countries, including the USA and countries in Europe. Several epidemiological, pathophysiological and clinical studies clearly indicate that two of the major independent risk factors for cardiovascular disease or events are being overweight, and obesity. Accordingly, weight loss and prevention of weight gain has to be considered one of the most important strategies to reduce the incidence of cardiovascular diseas…
