Oxidative Damage by 3-nitrotyrosine in Young Adults with Obesity: Its Implication in Chronic and Contagious Diseases (original) (raw)

Current Molecular Medicine

Abstract

Introduction: Cellular damage by oxidation occurs in numerous chronic diseases, such as obesity, type II diabetes, cardiovascular disease, nonalcoholic fatty liver, etc. The oxidized compound 3-nitrotyrosine is a marker of oxidative stress and protein oxidation damage. Objective: The article aims to assess whether 3-nitrotyrosine levels are higher in young people with obesity than in the same population without obesity. Method: Anthropometry and blood chemistry analyses were performed on 24 young Mexican participants (18-30 years old), categorized into two groups based on their waist circumference: Withobesity (≥ 80 cm women; ≥ 90 cm men) and without-obesity (<80 cm women; <90 cm men). Additionally, 3-nitrotyrosine blood values were quantified by ELISA. Results: Except for HDL-cholesterol, the mean values of lipids increased in women and men with obesity (p<0.05), and 3-nitrotyrosine concentration (nM/μg total protein) was higher by 60% in the group with-obesity compared to...
