title: Analysis of the expression levels of survivin and VEGF in patients with acute lymphoblastic leukemia.
abstract: The purpose of this study was to investigate the association between an inhibitor of apoptosis (survivin) and vascular endothelial growth factor (VEGF) expression in patients with acute lymphoblastic leukemia (ALL) prior to and following chemotherapy. Reverse transcription (RT)-PCR and western blotting were employed to analyze survivin and VEGF mRNA and protein expression. Moreover, the concentrations of survivin and VEGF were determined by enzyme-linked immunosorbent assay (ELISA). Our data revealed that survivin and VEGF were overexpressed in patients with ALL prior to treatment, while survivin levels were significantly decreased following treatment. In addition, there was a positive correlation between survivin and VEGF concentrations in plasma. In conclusion, analysis of survivin and VEGF expression levels may improve the clinical diagnosis and treatment of ALL.
