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.
METHODS
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 the group without-obesity, both for women (66.21 ± 23.85 vs. 40.69 ± 16.25, p<0.05) and men (51.72 ± 20.56 vs. 30.52 ± 5.21, p<0.05).
CONCLUSION
Oxidative damage measured by compound 3-nitrotyrosine was higher in the group with obesity than in the group without obesity, which, if not controlled, could lead to a chronic oxidative condition and thereby to a degree of cellular aging with adverse health effects.
