Serum levels of VEGF increased from 70.78 ± 1.1 to 131.7 ± 18.86 pg/mL, after 24 h and ninth day collection, respectively, whereas tumor-bearing mice treated with UA (50 μmol/kg body weight) demonstrated a significant decrease in VEGF serum levels at 24 h collection (42.53 ± 0.53 pg/mL) and on the ninth day of collection (61.63 ± 1.2 pg/mL). The gene discussed is VEGFA; the disease is neoplasm.
