regulatory system in physiology

W. Wang K. Virtanen Dowell Barak Kelly I. Zhang Kelly M. P. 1997;18 Suppl 4:S308–9. The age-associated fibrosis notwithstanding, cardiac function is relatively normal in young PPARα null mice. Chakrabarti Jove Tarr However, the response to several physiologic stressors is perturbed in mice lacking PPARα. Yue B.A. *FREE* shipping on qualifying offers. Finck et al. K. J.G. J.J. Reaven Mounting evidence suggests that the metabolic products of angiotensin I and II - initially thought to be biologically inactive - have key roles in cardiovascular physiology and pathophysiology. Kosm Biol Aviakosm Med. over 30 years ago [111]. Aviat Space Environ Med. Gavrilova J Appl Physiol. W. Campbell Weinheimer Thus, the end effects of PPAR/PGC-1α activity on pathologic remodeling are less than clear. Studies characterizing both strains of PGC-1α-deficient mice demonstrate perturbations in mitochondrial OXPHOS pathway function and depressed expression of genes encoding enzymes involved in these pathways.

Indeed, enhanced glucose oxidation during ischemia–reperfusion, especially in insulin resistant or diabetic heart, has been linked to improved recovery [50]. In support of this, partial inhibitors of mitochondrial FAO show promise as therapeutic treatment for cardiac disease [88–90]. Interestingly, the severity of the cardiac phenotype varies greatly between the two lines of null mice. Am J Physiol Endocrinol Metab. Ong Cardiomyopathy and/or conduction defects are also observed in mouse models with targeted deletion of the fatty acid oxidation enzymes [17–19]. Until recently, the PPARβ/δ (referred to as PPARβ from here on) isoform was little-studied. 1967;200:579–83. Finck W. et al. The renin-angiotensin system is an important component of the cardiovascular system.

However, metabolic inflexibility (uncontrolled FAO), toxic lipid intermediate accumulation, and reactive oxygen species accumulation have been observed in these hearts and are known to be linked to cardiomyopathic remodeling.
