VEGFA and neoplasm: In addition, we further quantitated the VEGF expression level in vivo in the tumor implants resected from SCID mice using real-time quantitative RT-PCR, and the result showed the expression level of VEGF isoform was similar among tumors from CL1-0 lung cancer cell lines overexpressing one of three VEGF isoforms (p = 0.953, one-way ANOVA)(Fig. 1B).
