Localization of Phosphorylated ERK/MAP Kinases to Mitochondria and Autophagosomes in Lewy Body Diseases
Open accessAbstract
We previously found that sustained ERK activation contributes to toxicity elicited by the parkinsonian neurotoxin 6‐hydroxydopamine. In addition, substantia nigra neurons from patients with incidental Lewy body disease, Parkinson's disease (PD), and diffuse Lewy body dementia (DLB) display abnormal phospho‐ERK accumulations in the form of discrete cytoplasmic granules. In this study, we investigated the subcellular localization of phospho‐ERK immunoreactive granules using double label confocal microscopy and immunoelectron microscopy. A small percentage of phospho‐ERK granules colocalized with the early endosome marker Rab5, but not with cathepsin D, 20S proteasome β‐subunit, or cytochrome P450 reductase. Phospho‐ERK immunoreactivity was often associated with mitochondrial proteins (MnSOD, 60 kDa and 110 kDa mitochondrial antigens), and some vesicular‐appearing phospho‐ERK granules appeared to envelop enlarged mitochondria by confocal laser scanning microscopy. Ultrastructural immuno‐gold studies revealed phospho‐ERK labeling in mitochondria and in association with bundles of ∼10 nm fibrils. Heavily labeled mitochondria were observed within autophagosomes. As mitochondrial pathology may play a pivotal role in Parkinson's and other related neurodegenerative diseases, these studies suggest a potential interaction between dysfunctional mitochondria, autophagy, and ERK signaling pathways.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
