Aging promotes accumulation of reactive oxygen/nitrogen species (ROS/RNS) in cardiomyocytes, which leads to contractile dysfunction and cardiac abnormalities. These changes may contribute to increased cardiovascular disease in the elderly. Inducible antioxidant pathways are regulated by nuclear erythroid 2 p45-related factor

Inheritable missense mutations in small molecular weight heat-shock proteins (HSP) with chaperone-like properties promote self-oligomerization, protein aggregation, and pathologic states such as hypertrophic cardiomyopathy in humans. We recently described that human mutant αB-crystallin (hR120GCryAB) overexpression that caused protein aggregation cardiomyopathy
