abstract = {Mitochondrial dysfunction has long been implicated in the
etiopathogenesis of Parkinson's disease (PD), based on the
observation that mitochondrial toxins can cause parkinsonism
in humans and animal models. Research into the function and
dysfunction of PD-associated genes revealed that at least
some of these genes interface with pathways regulating
various aspects of mitochondrial biology. Mutations in the
parkin gene, encoding an E3 ubiquitin ligase, are
responsible for the majority of autosomal recessive
parkinsonism. Our previous work revealed that parkin is a
stress-inducible protein with a wide neuroprotective
capacity, preventing cell death under various stress
conditions. We now present evidence that the acute
stress-protective activity of parkin and its capacity to
induce mitophagy are mediated by two separate and
independent pathways. While a functional autophagic
machinery and expression of the mitochondrial kinase PINK1
is required for parkin-induced mitophagy, these components
are dispensable for the anti-apoptotic activity of parkin.
We identified a signaling pathway that is essential for the
anti-apoptotic activity of parkin but not for induction of
mitophagy. In support of this concept, parkin seems to exert
adaptive effects on mitochondria depending on the severity
of mitochondrial damage. Parkin prevents stress-induced cell
death under moderate stress conditions with only minor
mitochondrial defects. However, when mitochondria are
irreversibly damaged in response to severe stress, parkin
can promote their elimination via mitophagy.},
