We chose a panel of hepatoma/hepatocarcinoma cells, reflecting the variable upregulation of FGFR3‐variants in HCC, i.e. Hep3B and HCC‐2 express rather isoform IIIb, HCC‐1.2 and HCC‐3 cells predominantly FGFR3‐IIIc, and HCC‐1.1 and HepG2, both variants at more or less similar extent (Table S3). The gene discussed is FGFR3; the disease is hepatocellular carcinoma.
