ABSTRACT
Objective To investigate the effect of M-CSF and GM-CSF on migration and expression of VEGF-A in breast cancer cell line 4T1.Methods Real-time PCR was used to detect VEGF-A mRNA expression in 4T1 cells treated by 5 ng/ml or 10 ng/ml M-CSF or GM-CSF.Ability of migration and metastasis of 4T1 cells were analyzed by scratch and Transwell assays.Results The relative expression of VEGF-A mRNA at 12 h and 24 h in 4T1 cells treated by 5 ng/ml or 10 ng/ml M-CSF were 17.81±2.49 and 17.48± 5.43,5.15±2.59 and 5.45±4.28,respectively,while those treated by GM-CSF were 9.77±2.39 and 7.61±2.80,6.53±2.41 and 6.30±2.89,respectively.M-CSF and GM-CSF can promote the expression of VEGF-A in 4T1 cells (P < 0.05).The relative expression of VEGF-A was higher in 4T1 cells treated for 12 h than that for 24 h (P < 0.01).M-CSF,GM-CSF and VEGF-A can promote metastasis of 4T1 cells (all P < 0.05),whereas no gross migration of 4T1 cells was showed by VEGF-A treatment.Conclusion M-CSF and GM-CSF can promote the migration and expression of VEGF-A in breast cancer cell line 4T1.
