Transactivation of the TIEG1 confers growth inhibition of transforming growth factor-β-susceptible hepatocellular carcinoma cells

Figure 1 Susceptibilities of various human hepatocyte (MIHA) and hepatocellular carcinoma cells (Hep3B, PLC, Huh7, HepG2, and Bel7404) to transforming growth factor-β. A: Cells were treated with 5 ng/mL transforming growth factor (TGF)-β1 for 96 h and cell survival was then determined by methylthiazoletetrazolium assays; B: Nuclear morphology of apoptotic TGF-β-treated Hep3B cells demonstrated by 4’,6-Diamidino-2-phenylindole staining and examined by fluorescence microscopy. Scale bar: 50 μm, 400 ×.
