Parkinson disease (PD) is a late onset, progressive neurodegenerative movement disorder with cardinal symptoms of tremor at rest, bradykinesia, postural instability, and rigidity. These motor symptoms of PD are caused by the progressive loss of dopaminergic neurons in the substantia nigra pars compacta (SNpc). However, despite PDs first modern observation in 1817, little is understood about the causes and molecular mechanisms behind dopaminergic neuron loss. The relatively weak understanding of pathological mechanisms has hindered the development of treatments to slow or halt the progression of PD. However, recently, mounting evidence from post-mortem, imaging, and retrospective studies suggest an important role …

Heme oxygenase-1 (HO-1) catalyzes the rate-limiting step in the catabolism of heme, which is released by necrotic cells in injured tissue. HO-1 expression is protective in cardiac and renal injury because it coordinates the degradation of pro-oxidant heme with the generation of equimolar quantities of iron (Fe2+) and the cytoprotective mole-cules carbon monoxide and biliverdin. While many studies have demonstrated that HO-1 expression is protective in numerous disease states, relatively few have examined the specific cellular compartment(s) through which HO-1 expression confers its protective effects. Our objective was to define the cellular compartments in which HO-1 expression is critical to …
