Additional MTS assays performed with SW480 (Figure 2B) and HCT116 (Figure 2C) colon cancer cells showed similar influences of PDGF (SW480: p<0.05 (48h); p<0.01(72h)), and VEGF (SW480: p<0.001 (24h and 48h); p<0.01 (72h); HCT116: p<0.05 (24h and 48h); p<0.01 (72h)) on tumor cell proliferation. The gene discussed is VEGFA; the disease is neoplasm.
