Key Event Relationship Description
ROS generation is known to activate different pathways leading to apoptosis, whereas depletion of energy production induces necrotic cell death.
Evidence Supporting this KER
There is functional mechanistic understanding supporting this relationship between KE3 and KE4.
ROS are known to stimulate a number of events and pathways that lead to apoptosis, triggered by ROS-induced ER stress signalling pathway (Lu et al., 2014), caspase-dependent and -independent apoptosis (Zhou et al., 2015), mitogen-activated protein kinase (MAPK) signal transduction pathways (reviewed in Cuadrado and Nebreda, 2010, Harper and LoGrasso, 2001).
Depletion of cellular ATP is known to cause switching from apoptotic cell death triggered by a variety of stimuli to necrotic cell death (Leist et al., 1997) suggesting that the level of intracellular ATP determines whether the cell dies by apoptosis or necrosis (Nicotera et al., 1998). There is strong proof that apoptosis requires energy, as it is a highly regulated process involving a number of ATP-dependent steps such as caspase activation, enzymatic hydrolysis of macromolecules, chromatin condensation, bleb formation and apoptotic body formation (Richter et al., 1996).
Uncertainties and Inconsistencies
Rats have been administered with DA at the dose of 1.0 mg/kg for 15 days. The histochemical analysis of hippocampus from these animals has revealed no presence of apoptotic bodies and no Fluoro-Jade B positive cells (Schwarz et al., 2014).

Domain of Applicability
Neuronal necrosis has been noted in sea lions accidentally exposed to DomA (Silvagni et al., 2005) that correlated well with the histopathological findings previously reported in experimental studies (Tryphonas et al., 1990).
