Enhancing glycolysis attenuates Parkinson’s disease progression in models and clinical databases
Open accessAbstract
Parkinson's disease (PD) is a common neurodegenerative disease that lacks therapies to prevent progressive neurodegeneration. Impaired energy metabolism and reduced ATP levels are common features of PD. Previous studies revealed that terazosin (TZ) enhances the activity of phosphoglycerate kinase 1 (PGK1), thereby stimulating glycolysis and increasing cellular ATP levels. Therefore, we asked whether enhancement of PGK1 activity would change the course of PD. In toxin-induced and genetic PD models in mice, rats, flies, and induced pluripotent stem cells, TZ increased brain ATP levels and slowed or prevented neuron loss. The drug increased dopamine levels and partially restored motor function. Because TZ is prescribed clinically, we also interrogated 2 distinct human databases. We found slower disease progression, decreased PD-related complications, and a reduced frequency of PD diagnoses in individuals taking TZ and related drugs. These findings suggest that enhancing PGK1 activity and increasing glycolysis may slow neurodegeneration in PD.

Terazosin activates PGK1 at much lower concentration, resulting in enhanced production of ATP and pyruvate.
“it also activates PGK1 at much lower concentration, resulting in enhanced productions of ATP and pyruvate (Fig. 4A) (Cai et al., 2019; Chen et al., 2015; Kokotos et al., 2024)”

The Introduction states that terazosin activates PGK1 and prevented falls in ATP and pyruvate levels in MPTP-treated mice. The Discussion describes a concentration-dependent relationship with ATP levels, but gives no comparison establishing that PGK1 is activated at a much lower concentration. (LLM, conf=0.86)

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.
