Lack of Correlation Between the CCR5-Δ32 Mutation and Acute Myeloid Leukemia in Iranian Patients

摘要

Chemokines and their receptors are crucially important in the pathogenesis of acute myeloblastic leukemia (AML). The CC chemokine receptor 5 (CCR5) is a specific chemokine receptor for CC chemokine ligand 3 (CCL3), CCL4 and CCL5 which all play key roles in identifying cancer properties and localization of leukemia cells. It has been demonstrated that the known mutation in CCR5 gene (CCR5-Δ32) leads to mal-expression of the receptor and affect its function. The aim of this study was to determine the rate of CCR5-Δ32 mutation within Iranian AML patients. In this study, blood samples were obtained from 60 AML patients and 300 healthy controls. The CCR5-Δ32 mutation was evaluated using Gap-PCR technique. Our results showed that CCR5-Δ32 mutation was not found in the patients, while three out of the controls had hetrozygotic form of this mutation. The rest of studied samples had the wild form of the gene. According to these findings, it can probably be concluded that the CCR5-Δ32 is not associated with susceptibility to AML in Iranian patients.
