Canonical and non-canonical Stat3 signaling pathways. In the canonical pathway, Stat3 is translocated to the nucleus and induce specific gene expression. Non-canonical signaling Stat3 is imported into mitochondria via GRIM-19. mitoStat3 regulates ATP synthesis, decreases ROS release, increases mitochondrial Ca2+ and MPTP opening.
