Article
Full-text available
Atherosclerosis is a chronic inflammatory disease, whose progression and stability are modulated, among other factors, by an innate and adaptive immune response. Prodiginines are bacterial secondary metabolites with antiproliferative and immunomodulatory activities; however, their effect on the progression or vulnerability of atheromatous plaque ha...

Background: Osteoarthritis (OA) is a progressive and multifactorial disease that is associated with aging. A number of changes occur in aged cartilage, such as increased oxidative stress, decreased markers of healthy cartilage, and alterations in the autophagy pathway. Propolis extracts contain a mixture of polyphenols and it has been proved that...
Article
Full-text available
The role of gut microbiota in the development of metabolic illnesses has been abundantly demonstrated. Recent studies suggest that gut microbiota alterations may also be related to the development of hypercholesterolemia. Therefore, we aimed to assess differences in the gut bacterial community profiles between hypercholesterolemic subjects and cont...
Article
Full-text available
Polyphenols from diverse sources have shown anti-inflammatory activity. In the context of atherosclerosis, macrophages play important roles including matrix metalloproteinases synthesis involved in degradation of matrix extracellular components affecting the atherosclerotic plaque stability. We prepared a propolis extract and pinocembrin in ethanol...
Article
Full-text available
Lipid-lowering response to statin therapy shows large interindividual variability. At a genome-wide significance level, single nucleotide polymorphisms (SNPs) in PCSK9 and HMGCR have been implicated in this differential response. However, the influence of these variants is uncertain in the Chilean population. Hence, we aimed to evaluate the contrib...
Article
Full-text available
Propolis has been shown to modulate the angiogenesis in both in vitro and in vivo models. Thus, we aimed to evaluate the antiangiogenic properties of an ethanolic extract of Chilean propolis (EEP) and Pinocembrin (Pn). Migration, formation of capillary-like structures of endothelial cells, and sprouting from rat aortic rings were used to assess the...
Article
New vessel formation plays a critical role in the progression and vulnerability of atherosclerotic lesions. It has been shown that polyphenols from propolis attenuate the progression of atherosclerosis and also exert inhibitory effects on angiogenic factors. However, the mechanisms underlying these effects are not completely understood. Thus, this...
Article
Full-text available
Propolis is a non-toxic natural substance with multiple pharmacological properties including anti-cancer, antioxidant, fungicidal, antibacterial, antiviral, and anti-inflammatory among others. The aim of this study was to determine the chemical and botanical characterization of Chilean propolis samples and to evaluate their biological activity agai...
Article
Full-text available
Several biological activities have been described for polyphenolic compounds, including a modulator effect on the immune system. The effects of these biologically active compounds on the immune system are associated to processes as differentiation and activation of immune cells. Among the mechanisms associated to immune regulation are epigenetic mo...
Article
Full-text available
Interindividual differences in activity and expression of the metabolizing enzymes cytochrome P450 (CYP) 3A4 and 3A5 and the multidrug efflux pump P-glycoprotein (P-gp, encoded by ABCB1 gene) contribute considerably to lipid-lowering efficacy of statin treatment in subjects with hypercholesterolemia. Variability in the activity of CYP3A4, CYP3A5 an...
Article
Statins are normally the first-line therapy for hypercholesterolemia (HC); however, the lipid-lowering response shows high interindividual variation. We investigated the effect of four polymorphisms in CYP3A4, CYP3A5 and ABCB1 genes on response to atorvastatin and CYP3A4 activity in Chilean subjects with HC. A total of 142 hypercholesterolemic indi...
Article
Full-text available
In the current study, we investigated the effect of propolis on diabetic mice undergoing propolis treatment (150 mg/kg/day) for a 6 week period. We also evaluated serum lipids, glucose, insulin levels and the effect on glucose uptake of 2-deoxy-D-[2,6-3H] glucose, [14C]-glycogen synthesis and [U-14C]-D-glucose decarboxylation induced by insulin in...
Article
Full-text available
Background: Diabetes mellitus type 2 (DMT2) is a well know cardiovascular risk factor and has been related to subclinic atherosclerosis, which might be explained by the presence of a common genetic basis in both diseases. Several polymorphisms of the cal-pain-10 gene (CAPNIO) have been associated with insulin resistance and DMT; nevertheless, there...
Article
Full-text available
Background: Adiponectin, encoded by ADIPOQ gene, is a hormone secreted by adipocytes that acts inhibiting the atheromatous plaque formation, modulating the inflammatory response and inhibiting the expression of adhesión molecules with subsequent inhibition of adhesión and macrophage activation, foam cells formation and migration and proliferación o...
Article
Background: Several genetic variants have been linked to the development ofcoronary heart disease and/or their riskfactors, including the S19Wand-1131T> C polymorphisms ofthe gene that encodes apolipoprotein A5 (APOA5). Thus, the objective ofthis study was to investígate the possible association between S19W and -1131T>C genetic variants ofAPOA5 an...

The main aim is the detection and identification of active ingredients with antibacterial and antifungal action on pathogens that affect the oral cavity. It also investigates the potential anti-inflammatory, hypoglycemic, antiangiogenic and antiatherogenic activity of active principles isolated from natural products.
