PPARβ/δ ligands induce VEGF in bladder cancer cells [39], humanbreast (T47D, MCF7), and prostate (LNCaP, PNT1A) cancer cell lines, along withits receptor flt-1 [22], but not (HT29, colon; HCT116, colon; LS-174T, colon; HepG2,hepatoma; and HuH7, hepatoma) cell lines [40]. This evidence concerns the gene VEGFA and hepatocellular carcinoma.
