Abstract :Purpose: Determination of proteomic differences plays an important role in biomarker investigations. Due to its heterogenic molecular background, identification of certain biomarkers is still a demand both for diagnosis and for prognosis of neuroblastoma. In this study, it is aimed to identify some marker proteins/mechanisms that may play role in neuroblastoma prognosis. Methods: A proteomic approach was performed for different risk groups of the disease by using matrix-assisted laser desorption ionization–time of flight (MALDI-TOF/TOF) approach. Mononuclear cell pools from blood samples of patients for risk groups were constructed and protein expression changes for different groups were identified. Real-time PCR analysis were performed for N-MYC, 11q, 1p and 17q status of these patients and risk groups were determined from tumor samples. Results: Manganese-superoxide dismutase (SOD2) protein was significantly increased in high-risk group of neuroblastoma patients. Conclusion: SOD2 may play an important role in neuroblastoma progression and be a candidate prognostic peripheral blood marker for neuroblastoma patients.
