The aim of our study was to analyze the serum levels of advanced oxidation protein products (AOPPs) and advanced glycation end products (AGEs), and protein nitrosylation in patients with B-chronic lymphocytic leukemia (B-CLL). AOPPs, AGEs, and S-nitrosylated were increased in B-CLL patients. The mutation of IgVH gene, CD 38, and Zap 70 expression were not associated with increased oxidative stress. The mutant 2677GT genotype was found to be associated with higher AGEs levels with respect to wild-type genotype, while as far the C3435T MDR1 polymorphism is concerned, subjects presenting wild-type genotype showed higher values of AOPPs with respect to heterozygous genotype. Our results suggest that B-CLL is associated with oxidative stress.

Abstract
The aim of our study was to analyze the serum levels of advanced oxidation protein products (AOPPs) and advanced glycation end products (AGEs), and protein nitrosylation in patients with B-chronic lymphocytic leukemia (B-CLL). AOPPs, AGEs, and S-nitrosylated were increased in B-CLL patients. The mutation of IgVH gene, CD 38, and Zap 70 expression were not associated with increased oxidative stress. The mutant 2677GT genotype was found to be associated with higher AGEs levels with respect to wild-type genotype, while as far the C3435T MDR1 polymorphism is concerned, subjects presenting wild-type genotype showed higher values of AOPPs with respect to heterozygous genotype. Our results suggest that B-CLL is associated with oxidative stress.Pubblicazioni consigliate
