Abstract

The effect of aging on oxidative modifications in DNA, proteins and lipids: The investigations in lymphocytes, erythrocytes, plasma and low density lipoproteins. Free radicals play an important role in the process of aging. In this study, we wanted to investigate the relationship between the oxidative stress and aging in humans by determining lipid and protein oxidation in plasma as well as DNA damage in lymphocytes of 55 healthy subjects who were divided into two subgroups of age; young (21-40 years) and elderly (61-85 years). In addition, we determined endogenous and stimulated lipid peroxide levels in low density lipoproteins (LDL) and erythrocytes of young and elderly subjects. According to our results, lipid peroxide and protein carbonyl levels in plasma as well as DNA damage in lymphocytes is found to increase in elderly subjects, lipid peroxide levels also increased in LDL and erythrocytes of elderly subjects. Our results, clearly show the presence of oxidative stress in elderly subjects.

Özet

Serbest radikaller yaşlanmada önemli rol oynamaktadır. Çalışmamızda, genç (21-40 yaş) ve yaşlı (61-85 yaş) olarak iki alt gruba ayrılan 55 sağlıklı kişinin plazmalarında lipit ye protein oksidasyonıı, lenfositlerinde DNA hasarı tayin edilerek oksidatif stres ile yaşlanma arasındaki ilişki araştırılmak istendi. Ayrıca, genç ve yaşlı kişilerin düşük dansiteli lipoproteinlerinde (LDL) ve eritrositlerinde endojen ve uyarmalı lipit peroksit düzeyleri ölçüldü. Sonuçlarımıza göre, yaşlı kişilerin plazmasında lipit peroksit ve protein karbonil düzeylerinin, lenfositlerden elde edilen DNA'da oksidatif hasarın arttığı bulundu. Ayrıca, yaşlı kişilerde LDL ve eritrositlerde lipit peroksit düzeylerinin arttığı saptandı. Bu sonuçlara göre, yaşlı kişilerde oksidatif stresin arttığı açıkça görülmektedir.
