Objective: To explore the effect of homeobox B2 (HOXB2) antisense oligodeoxynucleotides (asodn) on the proliferation and expression of primary human umbilical vein endothelial cells (HUVECs). Methods: Various concentrations of HOXB2 asodn modified by thiophosphate transfected the induction of liposome into HUVECs. MTT and RT-PCR methods were employed to determine the effect of different concentrations of asodn on the endothelial proliferation and the expression level of HOXB2 mRNA. Results: After the transfection of HOXB2 asodn, the endothelial proliferation was inhibited in a dose-dependent fashion. Simultaneously, the expression of HOXB2 mRNA decreased significantly. Conclusions: HOXB2 plays an important role in the proliferation of endothelia.
