Lipotoxicity in the heart.
Cardiomyopathy is associated with both rare genetic metabolic abnormalities and highly prevalent diseases characterized by elevated serum triglycerides and nonesterified fatty acids, such as obesity and type 2 diabetes. In these disorders, an imbalance between fatty acid uptake and utilization leads to the inappropriate accumulation of free fatty acids and neutral lipids within cardiomyocytes. ...
متن کاملApolipoprotein O is mitochondrial and promotes lipotoxicity in heart.
Diabetic cardiomyopathy is a secondary complication of diabetes with an unclear etiology. Based on a functional genomic evaluation of obesity-associated cardiac gene expression, we previously identified and cloned the gene encoding apolipoprotein O (APOO), which is overexpressed in hearts from diabetic patients. Here, we generated APOO-Tg mice, transgenic mouse lines that expresses physiologica...
متن کاملDGAT1 expression increases heart triglyceride content but ameliorates lipotoxicity.
Intracellular lipid accumulation in the heart is associated with cardiomyopathy, yet the precise role of triglyceride (TG) remains unclear. With exercise, wild type hearts develop physiologic hypertrophy. This was associated with greater TG stores and a marked induction of the TG-synthesizing enzyme diacylglycerol (DAG) acyltransferase 1 (DGAT1). Transgenic overexpression of DGAT1 in the heart ...
متن کاملDietary fat and heart failure: moving from lipotoxicity to lipoprotection.
There is growing evidence suggesting that dietary fat intake affects the development and progression of heart failure. Studies in rodents show that in the absence of obesity, replacing refined carbohydrate with fat can attenuate or prevent ventricular expansion and contractile dysfunction in response to hypertension, infarction, or genetic cardiomyopathy. Relatively low intake of n-3 polyunsatu...
متن کاملthe role of type-d personality, social support and self-compassion in prediction of health behaviors in coronary heart disease patients
نظر به اهمیت و تاثیر روزافزون عوامل روانی – اجتماعی در سلامت جسمی و تاثیر عوامل روان شناختی در بروز بیماریهای مختلف از جمله بیماریهای قلبی و عروقی این پژوهش با هدف کلی بررسی ارتباط تیپ شخصیتی d ، حمایت اجتماعی و خود دلسوزی در پیش بینی رفتارهای بهداشتی بیماران کرونر قلبی و تعیین تفاوت بین بیماران کرونر قلبی با و بدون جراحی و افراد سالم در این متغیرها و رفتارهای بهداشتی آنان، انجام گرفت. جامعه آ...
