The expressions of VEGF, MMP-2, and MMP-9 were increased in a stressed rodent model of ovarian carcinoma and another stressed rodent model of lung carcinoma (Thaker et al., 2006; Wu et al., 2015), and the same upregulations were detected in nasopharyngeal carcinoma tumor cells treated with norepinephrine (Yang E. V. et al., 2006). This evidence concerns the gene VEGFA and ovarian carcinoma.
