Particular attention will be paid to DOX-induced mitochondrial dysfunction in the rat heart and the role of ATP-sensitive potassium channels (KATP channels) as well as endogenous antioxidants - glutathione and gas transmitters. It is known that KATP channels are universal regulators of cellular functions and metabolism, which determines their key role in defense mechanisms. The work will investigate the functioning of the cardiovascular system in experimental DOX-induced heart failure (cardiotoxicity) in rats and in conditions of activation of endogenous defense mechanisms. Also, the search for antioxidant agents for the correction of cardiac disorders of different genesis (aging, DOX-induced heart failure) will be carried out, in particular the effect of KATP channel openers and new nanomaterials as potential antioxidants, etc. The role of melatonin deficiency (hypomelatoninemia) in the development of cardiac mitochondrial dysfunction will be established and the functional state of the cardiovascular system under conditions of inhibition of endogenous melatonin synthesis will be studied. popup.nrat_date 2024-12-09 Close
