Inhibitory effects of antisense oligodeoxynucleotide on expression of vascular endothelia growth factor by human hepatocarcinoma cells.

Background: It is widely recognized that the growth of solid tumor depends on angiogenesis. Vascular endothelia growth factor (VEGF) is an endothelial cell-specific mitogen that promotes angiogenesis in solid tumor. Inhibition of angiogenesis is considered a promising approach for cancer therapy, and treatments including administration of antisense drugs and RNA interference for the VEGF gene are geared to the suppression of tumor angiogenesis.
