Abstract

Mitochondria are highly dynamic organelles which fulfill a plethora of functions. In addition to their prominent role in energy metabolism, mitochondria are intimately involved in various key cellular processes, such as the regulation of calcium homeostasis, stress response and cell death pathways. Thus, it is not surprising that an impairment of mitochondrial function results in cellular damage and is linked to aging and neurodegeneration. Many lines of evidence suggest that mitochondrial dysfunction plays a central role in the pathogenesis of Parkinson's disease (PD), starting in the early 1980s with the observation that an inhibitor of complex I of the electron transport chain can induce parkinsonism. Remarkably, recent research indicated that several PD-associated genes interface with pathways regulating mitochondrial function, morphology, and dynamics. In fact, sporadic and familial PD seem to converge at the level of mitochondrial integrity.

  • Recessively inherited loss-of-function mutations in PINK1 and PRKN are the most common genetic causes of early-onset PD, which occurs in about 5%-10% of cases.

    “Recessively inherited loss-of-function mutations in PTEN-induced kinase 1 (PINK1) and the E3 ubiquitin ligase PRKN are the most common genetic causes for early-onset PD, which occurs in about 5%–10% of cases [1, 2].”

    From miRNA family miR-29 inhibits PINK1-PRKN signaling via ATG9A (2026) · cites this paper as [2]

    The Introduction identifies loss-of-function mutations in parkin (PRKN) and PINK1 as causes of autosomal recessive PD. Sections 2.1.1.1 and 2.1.2.1 describe PINK1 as the second most common cause of recessive early-onset parkinsonism after parkin, which accounts for the majority of recessive cases. Section 2.1 says familial PD accounts for up to 10% of PD cases and usually, but not always, has early onset; it does not establish that early-onset PD itself occurs in 5%–10% of cases.

  • Loss-of-function mutations in PINK1 and PRKN result in early-onset Parkinson disease.

    “Loss-of-function mutations in the genes encoding PINK1 and PRKN result in early-onset Parkinson disease (EOPD).”
  • α-Synuclein causes dysfunction of mitochondrial complex I in PD, which increases ROS and oxidative stress.

    “α-Synuclein has been reported to cause dysfunction of mitochondrial complex I in PD which in turn increases levels of ROS and consequently ROS-induced oxidative stress (Winklhofer and Haass 2010).”

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.
