Oxidative stress and sarcomeric proteins.
Oxidative stress accompanies a wide spectrum of clinically important cardiac disorders, including ischemia/reperfusion, diabetes mellitus, and hypertensive heart disease. Although reactive oxygen species (ROS) can activate signaling pathways that contribute to ischemic preconditioning and cardioprotection, high levels of ROS induce structural modifications of the sarcomere that impact on pump f...
متن کاملSarcomeric proteins and inherited cardiomyopathies.
Over the last two decades, a large number of mutations have been identified in sarcomeric proteins as a cause of hypertrophic, dilated or restrictive cardiomyopathy. Functional analyses of mutant proteins in vitro have revealed several important functional changes in sarcomeric proteins that might be primarily involved in the pathogenesis of each cardiomyopathy. Creation of transgenic or knock-...
متن کاملSome acute phase proteins, oxidative stress biomarkers and antioxidant enzyme activities in ewes with pregnancy toxemia
The aim of this study is to investigate antioxidant enzymes, oxidative stress biomarkers and the acute phase proteins levels for subclinical and clinical pregnancy toxemia and to determine the effect of early diagnosis on the success of curing. According to the results of clinical and biochemical parameters, from 39 ewes, 10 were healthy ewes (control group), 13 ewes had subclinical pregnancy t...
متن کاملTocotrienol Modulates the Expression of Proteins in Oxidative Stress-Induced Caenorhabditis Elegans
Objective: Oxidative stress that damages proteins result in aging and age related diseases. The aim of this study is to determine the effect of tocotrienol rich fraction (TRF) on the expression of proteins in oxidative stress-induced caenohabditis elegans (C.elegans) which has homologous genes to humans. Methods: The worms were treated with TRF prior to, after and continuously in separate group...
متن کاملHeme Proteins, Heme Oxygenase-1 and Oxidative Stress
Heme is ferrous protoporphyrin-IX that is the prosthetic group of hemoproteins, such as hemoglobin, myoglobin and cytochromes that are of vital importance. In contrast, “free heme”, a protein-unbound heme, that is either just synthesized but yet not incorporated into hemoproteins, or that is released from hemoprotein under oxidative conditions, is highly toxic, since it catalyzes the production...
