Objective:
To explore the expression of insulin-like growth factor binding protein 3 (IGFBP3) in acute myeloid leukemia and its clinical significance.
Methods:
Using GAPDH as internal reference, IGFBP3 gene expression was detected in the bone marrow mononuclear cells of 43 de novo AML patients, 36 patients with complete remission (CR) and 28 cases of controls by using SYBR-Green I real-time quantitative PCR, the differences of gene expression between the three groups were compared.
Results:
IGFBP3 gene expression level in the de novo group were lower than that in CR group and control group (P < 0.05), but there was no statistically significant difference of IGFBP3 expression level in CR group and control group (P > 0.05).
Conclusions:
The IGFBP3 as a tumor suppressor gene may play a role in the pathogenesis of acute myeloid leukemia, its expression level is recovered after complete remission, therefore, IGFBP3 can be used as an indicator of evaluating clinical curative effect.
