Myocardial fatty acid uptake through CD36 is indispensable for sufficient bioenergetic metabolism to prevent progression of pressure overload-induced heart failure
The energy metabolism of the failing heart is characterized by reduced fatty acid (FA) oxidation and an increase in glucose utilization. However, little is known about how energy metabolism-function relationship is relevant to pathophysiology of heart failure. Recent study showed that the genetic de...

description | The energy metabolism of the failing heart is characterized by reduced fatty acid (FA) oxidation and an increase in glucose utilization. However, little is known about how energy metabolism-function relationship is relevant to pathophysiology of heart failure. Recent study showed that the genetic deletion of CD36 (CD36KO), which causes reduction in FA use with an increased reliance on glucose, accelerates the progression from compensated hypertrophy to heart failure. Here, we show the mechanisms by which CD36 deletion accelerates heart failure in response to pressure overload. CD36KO mice exhibited contractile dysfunction and death from heart failure with enhanced cardiac hypertrophy and interstitial fibrosis when they were subjected to transverse aortic constriction (TAC). The pool size in the TCA cycle and levels of high-energy phosphate were significantly reduced in CD36KO-TAC hearts despite an increase in glycolytic flux. De novo synthesis of non-essential amino acids was facilitated in CD36KO-TAC hearts, which could cause a further decline of the pool size. The ingestion of a diet enriched in medium-chain FA improved cardiac dysfunction in CD36KO-TAC hearts. These findings suggest that myocardial FA uptake through CD36 is indispensable for sufficient ATP production and for preventing an increased glycolytic flux-mediated structural remodeling during pressure overload-induced hypertrophy. |
