Article Title: Gentian violet induces apoptosis and ferroptosis via modulating p53 and MDM2 in hepatocellular carcinoma

doi:

Figure Lengend Snippet: The proposed molecular mechanisms of GV-induced killing of HCC. When NOX is inhibited by GV, Hep27 is increased, which leads to the blockade of the ubiquitination and degradation of p53 by MDM2. Consequently, the levels of p53 and MDM2 are increased. GV also directly increases p53 level. Increased p53 and MDM2 levels trigger ferroptosis and mitochondrial apoptosis (through the activation of caspase 8) by a coordinated ROS cross point and downstream signaling cascades. On the other hand, GV also triggers death receptor apoptosis (through the activation of caspase 9) by upregulating death receptors DR4/5 and ligands FAS-ligand and TRAIL.
