The luciferase activity of the different Lt- and Ct-SLCO1B3 reporter gene constructs was analyzed in the hepatocellular carcinoma cell lines HepG2 (Figure 2A) and Hep3B (Figure 2B) and in the colorectal carcinoma cell lines DLD1 (Figure 2C), T84 (Figure 2D) and Caco-2 (Figure 2E). The gene discussed is SLCO1B3; the disease is colorectal carcinoma.
