Upregulation of Neutrophil Gelatinase-associated Lipocalin, NGAL/Lcn2, in β-Thalassemia Patients

Background the major consequences in β- thalassemia is iron overload. Oxidative statuses have been reported in β-thalassemia patients by several studies. It has been proven that iron plays a critical role in the formation of reactive oxygen species (ROS). More recently, we have found the induction of Lcn2/NGAL expression under oxidative stress condition. In this study, it was assumed that NGAL should be upregulated in β-thalassemia patients because of oxidative stress condition. s ment of NGAL expressions in 25 adult β-thalassemia and 9 pediatric patients was performed by semiquantitative RT-PCR, real-time RT-PCR and ELISA. s β-thalassemia patients upregulated NGAL expression compared with the normal samples but no upregulation was observed in pediatric patients. sions lation may play an important role in decreasing ROS or iron in β-thalassemia patients.
