ABSTRACT
OBJECTIVE:
The aim of this study is to investigate the expression of vascular endothelial growth factor (VEGF) in the serum of patients with chronic myeloid leukemia (CML) and the effect of VEGF on cell proliferation. PATIENTS ANDMETHODS:
Serum VEGF levels in 12 CML patients (7 chronic phase, 5 blast crisis phase) were measured using enzyme linked immunosorbent assay (ELISA). VEGF expression was interfered by transfection of K562 cells. VEGF mRNA levels in transfected K562 cells were determined using RT-PCR and the effect of VEGF on the proliferation of transfected K562 cells was investigated.RESULTS:
VEGF expression levels were significantly higher in CML patients than normal controls and significantly increased during blast crisis phase than during chronic phase. Compared to controls, the proliferation of the K562 cells was suppressed when VEGF expression was inhibited. However, the inhibited proliferation of K562 cells after gene silencing of VEGF was partially abolished after introducing exogenous VEGF into the cells.CONCLUSIONS:
VEGF plays an important role in the initiation and development of CML and monitoring serum VEGF assists guiding the treatment and predicting the prognosis of CML.
