VEGFA and neoplasm: In an attempt to understand the difference in tumor size, we examined the expression of several genes involved in apoptosis (BAD, BAX, and PUMA), cell proliferation [cyclin D1 (CCND1)], metastasis (MMP9, CDH1, CDH2, and VIM), and angiogenesis [vascular endothelial growth factor (VEGF)] using RT‐qPCR (Fig. S11).
