英文摘要	The usage of RNA interference for gene knockdown in zebrafish through expression of the small interfering RNA mediators from DNA vectors has created a lot of excitement in the research community. In this work, the ability of human cytomegalovirus immediate early promoter (CMV promoter)-driven short hairpin RNA (shRNA) expression vector to induce shRNA against vascular endothelial growth factor (VEGF) gene in zebrafish was tested, and its effects on VEGF-mediated vasculogenesis and angiogenesis were evaluated. Altogether four vectors targeting various locations of VEGF gene were constructed, and pSI-V4 was proven to be the most effective one. Microinjection of pSI-V4 into the zebrafish embryos resulted in defective vascular formation and down regulation of VEGF expression. In situ hybridization analysis indicated that silencing VEGF gene expression by pSI-V4 resulted in down regulation of neuropilin-1 (NRP1), a potent VEGF receptor. Knockdown of VEGF expression by morpholino gave the same result. This provided evidence that the VEGF-mediated angiogenesis in zebrafish was in part dependent on NRP1 expression. The results contributed to a better understanding of molecular mechanisms of cardiovascular development and provided a potential promoter for making inducible knockdown in zebrafish.; The usage of RNA interference for gene knockdown in zebrafish through expression of the small interfering RNA mediators from DNA vectors has created a lot of excitement in the research community.
