Abstract

Neuroprotection targeting mitochondrial dysfunction has been proposed as a potential therapeutic strategy for Parkinson's disease (PD). Ursodeoxycholic acid (UDCA) has been shown to prevent neuronal damage; however, the role of UDCA in PD is poorly understood. This study aimed to investigate the neuroprotective effects of UDCA on PD and its underlying mechanisms. We used MPTP/MPP+-induced PD models, including MPTP-induced mice, primary cultures of mice mesencephalic neurons and MPP+-treated neuro-2a cells to examine the effects of UDCA on PD pathogenesis. The results showed that UDCA improved behavioral performance and protected dopaminergic neurons in MPTP mice. UDCA improved cell viability and decreased cell death in MPP+-treated cells. UDCA inhibited reactive oxygen species accumulation, mitochondrial membrane potential collapse, and ATP depletion in neuro-2a cells. UDCA improved movement dysfunction, ameliorated autophagic flux and alleviated apoptosis. Furthermore, UDCA could activate the AMPK/mTOR and PINK1/Parkin pathways. In conclusion, UDCA may improve PD by regulating mitochondrial function, autophagy, and apoptosis, involving AMPK/mTOR and PINK1/Parkin pathways. These results open new perspectives for pharmacological use of UDCA in PD.

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.
