Efectos de las proantocianidinas sobre las alteraciones producidas por la estimulación con aldosterona en células cardíacas

Abstract

[ES] Las enfermedades cardiovasculares son desde hace tiempo la primera causa de muerte a nivel mundial. Investigar los principales mecanismos de acción de estas patologías ayuda a conocer, tratar e incluso poder prevenir este tipo de enfermedades. La aldosterona, una hormona esteroidea que ejerce su acción a través de la unión con el receptor de mineralocorticoide (RM), es una pieza fundamental en la regulación de la reabsorción de agua y la presión arterial. El exceso de aldosterona está asociado con enfermedades cardiovasculares y metabólicas, dentro de las que las que podemos encontrar anormalidades vasculares como la disfunción endotelial, remodelado vascular y cardiaco, aumento de la presión arterial, estrés oxidativo y fibrosis. En este trabajo se estudiarán las proantocianidinas como un posible agente cardioprotector en células de miocardio ventricular de rata H9c2, actuando como antagonista del RM y disminuyendo los efectos deletéreos del exceso de aldosterona sobre distintos aspectos relacionados con la hipertrofia cardiaca, una patología asociada con la hipertensión. Los resultados obtenidos sugieren que las proantocianidinas contrarrestan los efectos negativos de la aldosterona sobre las células H9c2 a nivel de supervivencia celular, daño en el genoma y diferenciación celular. Son necesarias nuevas investigaciones sobre este sistema para poder llegar a utilizar este agente como tratamiento en casos de hipertrofia cardiaca asociada a hiperaldosteronismo

[EN] Cardiovascular diseases have long been the leading cause of death worldwide. Investigating the main mechanisms of action of these pathologies helps to understand, treat and even prevent this type of disease. Aldosterone, a steroid hormone that exerts its action through binding to the mineralocorticoid receptor (RM), is a key player in the regulation of water reabsorption and blood pressure. Aldosterone excess is associated with cardiovascular and metabolic diseases, among which we can find vascular abnormalities such as endothelial dysfunction, vascular and cardiac remodeling, increased blood pressure, oxidative stress and fibrosis. In this work, proanthocyanidins will be studied as a possible cardioprotective agent in H9c2 rat ventricular myocardial cells, acting as an antagonist of the RM and reducing the deleterious effects of excess aldosterone on different aspects related to cardiac hypertrophy, a pathology associated with hypertension. The results obtained suggest that proanthocyanidins counteract the negative effects of aldosterone on H9c2 cells at a cell survival level, genome damage and cell differentiation. New research on this system is necessary to be able to use this agent as a treatment in cases of cardiac hypertrophy associated with hyperaldosteronism
