Conceptos básicos en biología molecular relacionados con la genética y la epigenética
2017
Resumen La observacion de que «lo mismo no sirve para todos» en la prevencion y el tratamiento de las enfermedades cardiovasculares, entre otras, ha propulsado el concepto de medicina de precision. Su objetivo es proporcionar las mejores intervenciones basadas en la informacion adicional que aporta el genoma. El genoma humano se compone de miles de millones de pares de bases que contienen un codigo que controla como se expresan los genes. Este codigo depende de reguladores no estaticos que rodean el ADN y constituyen el epigenoma. Ademas, los factores ambientales tambien desempenan un papel importante en esta compleja regulacion. Se presenta una perspectiva general sobre los conceptos basic…
El suero de seno coronario tras un infarto de miocardio induce angiogénesis y reparación de la obstrucción microvascular. Implicación del factor indu…
2018
Resumen Introduccion y objetivos El objetivo es estudiar la angiogenesis coronaria inducida por el suero coronario y la implicacion del factor inducible por hipoxia-1A (FIH-1A) en la reparacion de la obstruccion microvascular (OMV) tras un infarto agudo de miocardio (IAM). Metodos Se indujo un IAM en cerdos mediante oclusion coronaria durante 90 min. Se dividio a los animales entre 1 grupo de control y 4 grupos con IAM: sin reperfusion y 1 min, 1 semana y 1 mes tras la reperfusion. Se cuantificaron la OMV y la densidad microvascular. Se determino la capacidad angiogenica del suero coronario mediante una prueba de tubulogenesis in vitro. Se determinaron las concentraciones circulantes del FI…
Système endocannabinoïde : effets sur le métabolisme glucidique, mais aussi lipidique
2016
Resume Le systeme endocannabinoide (SEC) est compose de recepteurs couples aux proteines G : Cannabinoid type 1-receptor (CB 1 -R) et Cannabinoid type 2-receptor (CB 2 -R), de leurs ligands endogenes (anandamide [AEA], et 2-acylglycerol [2-AG]), et des enzymes responsables de leur synthese et de leur degradation. Bien que les recepteurs CB 1 -R et CB 2 -R furent initialement decrits au niveau du systeme nerveux central, ils sont presents dans de nombreux tissus peripheriques, ou ils sont impliques dans le metabolisme, la croissance, et l’inflammation. Apres le retrait commercial du rimonabant, pour des effets secondaires psychiatriques, un agoniste inverse du recepteur CB 1 (CB 1 -R), desti…
Association Between Fatty Acids of Blood Cell Membranes and Incidence of Coronary Heart Disease
2019
Objective— To examine the associations between baseline levels of fatty acids in blood cell membranes and their 1-year changes with the incidence of coronary heart disease (CHD) in older adults at high cardiovascular disease risk. Approach and Results— This is a case-control study nested in the PREDIMED trial (Prevención con Dieta Mediterránea), with 136 CHD cases and 272 controls (matched on age, sex, body mass index, intervention group, and time of permanence in the study to the time event). We used gas chromatography to measure the proportion of 22 fatty acids in blood cell membranes at baseline and after 1 year. Conditional logistic regression was used to estimate odds ratios (ORs) and…
Soluble Platelet Release Factors as Biomarkers for Cardiovascular Disease
2021
Platelets are the main players in thrombotic diseases, where activated platelets not only mediate thrombus formation but also are involved in multiple interactions with vascular cells, inflammatory components, and the coagulation system. Although in vitro reactivity of platelets provides information on the function of circulating platelets, it is not a full reflection of the in vivo activation state, which may be relevant for thrombotic risk assessment in various disease conditions. Therefore, studying release markers of activated platelets in plasma is of interest. While this type of study has been done for decades, there are several new discoveries that highlight the need for a critical a…
Autosomal recessive hypercholesterolemia in Spain.
2017
Abstract Background and aims Autosomal recessive hypercholesterolemia (ARH) is a very rare disease, caused by mutations in LDL protein receptor adaptor 1 (LDLRAP1). It is characterized by high levels of low-density lipoprotein cholesterol (LDL-C) and increased risk of premature cardiovascular disease. We aimed to characterize ARH in Spain. Methods Data were collected from the Dyslipidemia Registry of the Spanish Atherosclerosis Society. A literature search was performed up to June 2017, and all diagnostic genetic studies for familial hypercholesterolemia of Spain were reviewed. Results Seven patients with ARH were identified, 6 true homozygous and one compound heterozygous with a novel muta…
ADMA and arginine derivatives in relation to non-invasive vascular function in the general population.
2015
Nitric oxide produced from l-arginine is central to vascular homeostasis. Little is known about the relationship between arginine derivatives including asymmetric dimethylarginine (ADMA) and non-invasive vascular function measures in the general population.In 5000 individuals (median age 56; 25th/75th percentile: 46, 65; 49% women) taking part in the population-based Gutenberg Health Study (Mainz area, Germany), we measured the relationship between the arginine derivatives asymmetric dimethylarginine (ADMA), N-monomethyl l-arginine (NMMA), symmetric dimethylarginine (SDMA) and l-arginine with flow-mediated dilation (FMD) and peripheral arterial tonometry (PAT). Weak bivariate correlations w…
