VEGFA and neoplasm: The level of VEGF correlated with the tumor volumechange (Figure 6B).The concentration of VEGF in tumor control rats increased significantlywhen tumor size reached a peak value, whereas the concentration ofVEGF in carboplatin-treated rats decreased significantly comparedwith the tumor control rats, and neither rHuEPO and romiplostim monotherapynor combination treatment increased VEGF levels in vivo.
