Abstract

Nuclear factor (erythroid-derived 2)-like 2 and its Caenorhabditis elegans ortholog, SKN-1, are transcription factors that have a pivotal role in the oxidative stress response, cellular homeostasis, and organismal lifespan. Similar to other defense systems, the NRF2-mediated stress response is compromised in aging and neurodegenerative diseases. Here, we report that the FDA approved drug hydralazine is a bona fide activator of the NRF2/SKN-1 signaling pathway. We demonstrate that hydralazine extends healthy lifespan (~25%) in wild type and tauopathy model C. elegans at least as effectively as other anti-aging compounds, such as curcumin and metformin. We show that hydralazine-mediated lifespan extension is SKN-1 dependent, with a mechanism most likely mimicking calorie restriction. Using both in vitro and in vivo models, we go on to demonstrate that hydralazine has neuroprotective properties against endogenous and exogenous stressors. Our data suggest that hydralazine may be a viable candidate for the treatment of age-related disorders.

  • Hydralazine has anti-neurodegenerative efficacy based on action on antioxidative stress mechanisms, including activation of Nrf2 signaling, increased mitochondrial respiration and ATP production, and activation of autophagy.

    “Hydralazine, an FDA-approved antihypertensive, has been chosen for its recently discovered anti-neurodegenerative efficacy based on his action on antioxidative stress mechanisms, such as activation of the Nrf2 signaling pathway, increase of mitochondria respiration capacity and adenosine triphosphate production, activation of autophagy, which facilitates intracellular aggregate clearance [102].”

    From Treatment of Alzheimer’s Disease: Beyond Symptomatic Therapies (2023) · cites this paper as [102]

    The Results section ('Hydralazine NRF2/SKN-1 activation provides neuroprotection'; page unavailable) reports protection in rotenone-stressed neurons and improved motility in a C. elegans tauopathy model; the Discussion reports NRF2/SKN-1 activation. The Discussion describes altered mitochondrial respiration only as a possible additional mechanism, citing work in yeast. Our copy does not establish increased respiration or ATP production, or activation of autophagy and aggregate clearance. (LLM, conf=0.88)

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.
