In order to establish the impact of the GCS-inhibitor Genz (Figure 1A) and the CAD aripiprazole (Figure 1B) on the cell cycle of hepatoma cells, Huh7 and Hepa 1-6 hepatocellular carcinoma cells were cultivated in the presence of the thymidine mimicry 5-Bromo-2′-desoxyuridine (BrdU). The gene discussed is UGCG; the disease is hepatocellular carcinoma.
