Hypothalamic S-Nitrosylation Contributes to the Counter-Regulatory Response Impairment following Recurrent Hypoglycemia

2013

http://www.ncbi.nlm.nih.gov/pubmed/23894333; International audience; AIMS: Hypoglycemia is a severe side effect of intensive insulin therapy. Recurrent hypoglycemia (RH) impairs the counter-regulatory response (CRR) which restores euglycemia. During hypoglycemia, ventromedial hypothalamus (VMH) production of nitric oxide (NO) and activation of its receptor soluble guanylyl cyclase (sGC) are critical for the CRR. Hypoglycemia also increases brain reactive oxygen species (ROS) production. NO production in the presence of ROS causes protein S-nitrosylation. S-nitrosylation of sGC impairs its function and induces desensitization to NO. We hypothesized that during hypoglycemia, the interaction b…

Iron metabolism markers and l-arginine derivatives in coronary artery disease : highlighting, assessment and role of oxidative stress in acute myocar…

2015

Myocardial infarction (MI) is mostly caused by complications of atherosclerosis, whose the development would be initiated by a dysfunction of the vascular endothelium, characterized by an inflammatory condition and oxidative stress.In this pathogenesis, iron interacts at different levels and also has a major role in the development of endothelial dysfunction. Hepcidin and erythroferrone (discovered earlier as the myonectin/CTRP 15) participate in a major way in regulating certain stages of iron metabolism.Asymmetric dimethylarginine (ADMA), a marker of endothelial dysfunction is associated with most cardiovascular risk factors. Symmetrical dimethyl-arginine (SDMA), its stereoisomer, has an …
