Numerous tumors produce VEGF; clinically, inhibiting VEGF‐induced angiogenesis can significantly suppress tumor growth in vivo, which emphasizes the critical role of VEGF in neoplasm growth (Millauer, Shawver, Plate , Risaui, & Ullrich, 1994; Saleh, Stacker, & Wilks, 1996). The gene discussed is VEGFA; the disease is neoplasm.
