We were disappointed that there is no alterations in cell proliferation and expression of tumor progression-related genes including HIF1A, TGFβ1 and VEGF at RNA levels but decrease of trans-well cell migration assays in HCC cells PLC5, SNU449 and Huh7 (Supplementary Figure 1A–1C). The gene discussed is VEGFA; the disease is hepatocellular carcinoma.
