Ang-(1-7) inhibited the expression of angiogenic factors PIGF, VEGF and VEGF receptors in tumor samples. The expression level of PIGF, VEGF and VEGF receptors between Y703F-Ang-(1-7), Y703F-Luc or PBS groups were determined by real-time RT-PCR, and data were quantified by the comparative ΔΔCt method by using human GAPDH as the internal standard. *p<0.05 compared with PBS groups, #p<0.05 compared with Y703F-Luc groups.
