Figure 6.Graphical representation illustrating the mechanism underlying Dox-induced cell apoptosis. Dox induced ROS generation, which suppressed PHD. This stabilized nuclear HIF1A, promoted IGFBP3, and enhanced its extracellular association with IGF1. This interaction blocked survival signaling and resulted in cell apoptosis.
