DNM1L and cardiac arrest: Additionally, research by Yuan et al. found that extracellular signal-regulated kinase (ERK) activation, dynamin-related protein 1 (Drp1)/mitochondrial fusion protein 2 (Mfn2)-dependent mitochondrial dynamics imbalance, and excessive autophagy are involved in cerebral ischemia-reperfusion injury leading to neurologic damage after cardiac arrest/cardiopulmonary resuscitation.
