Figure 11 Possible mechanisms by which tectorigenin induces apoptosis in human hepatocellular carcinoma HepG2 cells. Tectorigenin produces reactive oxygen species and increases Ca2+ concentration in cytoplasm of HepG2 cells, leading to the depletion of mitochondrial membrane potential and release of cytochrome c from mitochondria. Cytochrome c facilitates apoptosis of HepG2 cells by activating caspase cascade. Tec: Tectorigenin; ROS: Reactive oxygen species; C: Cytochrome c; Casp: Caspase; AIF: Apoptosis inducing factor; MMP: Mitochondrial membrane potential.
