Objective: To explore the effects of HOXB2 anti-sense oligodeoxynucleotides (asodn) on the proliferation and the expression of human umbilical vein endothelial cells (HUVECs).
Methods: Various concentrations of HOXB2 ASODN modified by thiophosphate were transfected into HUVECs by liposome mediation. MTT and RT-PCR methods were employed to determine the influence of different concentrations of ASODN on endothelial proliferation and the expression level of HOXB2 mRNA.
Results: After the transfection of HOXB2 ASODN, the endothelial proliferation was inhibited in dose-dependent manner. Simultaneously, the expression level of HOXB2 mRNA decreased significantly.
Conclusion: HOXB2 might play important roles in the proliferation of endothelial cells.
