Summary of "Postnatal early overfeeding induces cardiovascular dysfunction by oxidative stress in adult male Wistar rats."

Obesity is associated with innumerous comorbidities, including cardiovascular diseases, that occur by various mechanisms, including hyperactivation of the renin angiotensin system, oxidative stress and cardiovascular overload. Postnatal early overfeeding (PO) leads to metabolic imprinting that induces weight gain throughout life, and in this paper, we aimed to evaluate cardiovascular parameters and cardiac molecular changes due to obesity induced early in life by PO.

Medical and Biotech [MESH] Definitions

A disturbance in the prooxidant-antioxidant balance in favor of the former, leading to potential damage. Indicators of oxidative stress include damaged DNA bases, protein oxidation products, and lipid peroxidation products (Sies, Oxidative Stress, 1991, pxv-xvi).

A protein deglycase that repairs methylglyoxal- and glyoxal-glycated amino acids and proteins, releasing repaired proteins and lactate or glycolate. It deglycates CYSTEINE, ARGININE and LYSINE residues to reactivate proteins by reversing glycation and prevent the formation of ADVANCED GLYCATION END PRODUCTS. It protects cells against OXIDATIVE STRESS and CELL DEATH by functioning as an oxidative stress sensor and redox-sensitive MOLECULAR CHAPERONE and PROTEASE. Mutations in the PARK7 gene are associated with autosomal-recessive, early-onset PARKINSON DISEASE.

Methods and procedures for the diagnosis of diseases or dysfunction of the cardiovascular system or its organs or demonstration of their physiological processes.

The appearance of carbonyl groups (such as aldehyde or ketone groups) in PROTEINS as the result of several oxidative modification reactions. It is a standard marker for OXIDATIVE STRESS. Carbonylated proteins tend to be more hydrophobic and resistant to proteolysis.

A direct-acting oxidative stress-inducing agent used to examine the effects of oxidant stress on Ca(2+)-dependent signal transduction in vascular endothelial cells. It is also used as a catalyst in polymerization reactions and to introduce peroxy groups into organic molecules.
