Although high levels of fatty acids has been demonstrated to have adverse effects in the normal heart, its effect in the obese/diabetic heart is less clear. In the present study we have examined how an acute fat-load on the heart diet-induced obese (DIO) mice (20 week on a high-fat diet) and age-matched controls (CON) will influence mitochondrial respiration. We found reduced OXPHOS respiration in isolated mitochondrial from DIO as compared to CON hearts. By subjecting CON hearts to a high fat-load (elevated levels of fatty acids prior to mitochondrial isolation), OXPHOS respiration and RCR (respiratory coupling ratio) were reduced. These changes were not observed in mitochondria from DIO hearts, which may suggest that in diabetes, the heart undergoes adaptation to chronic exposure of elevated circulating fatty acids, which protect these hearts from the adverse effects of an acute fat-load.".
