Abstract

Parkinson's disease (PD) is a neurodegenerative disorder primarily affecting the dopaminergic neurons in the nigrastriatal pathway resulting in debilitating motor impairment in both familial and sporadic cases. Histone deacetylase (HDAC) inhibitors have been recently implicated as a therapeutic candidate because of their ability to correct the disrupted HDAC activity in PD and other neurodegenerative diseases. Sodium butyrate (SB), an HDAC inhibitor, reduces degeneration of dopaminergic neurons in a mutant alpha-synuclein Drosophila transgenic model of familial PD. Chronic exposure to the pesticide rotenone also causes selective degeneration of dopaminergic neurons and causes locomotor impairment and early mortality in a Drosophila model of chemically induced PD. This study investigated the effects of sodium butyrate on locomotor impairment and early mortality in a rotenone-induced PD model. We show that treatment with 10mM SB-supplemented food rescued the rotenone-induced locomotor impairment and early mortality in flies. Additionally, flies with the genetic knockdown of HDAC activity through Sin3A loss-of-function mutation (Sin3A(lof)) were resistant to rotenone-induced locomotor impairment and early mortality. Furthermore, SB-supplemented Sin3A(lof) flies had a modest additive effect for improving locomotor impairment. We also show SB-mediated improvement of rotenone-induced locomotor impairment was associated with elevated dopamine levels in the brain. However, the possibility of SB-mediated protective role through mechanisms independent from dopamine system is also discussed. These findings demonstrate that HDAC inhibitors like SB can ameliorate locomotor impairment in a rotenone-induced PD model.

  • SCFAs can reduce degeneration of dopaminergic neurons and improve dyskinesia in a rotenone-induced Drosophila Parkinson's disease model.

    “SCFAs may be able to modulate neuroinflammation in (HDACi), can reduce the degeneration of dopaminergic neurons and improve dyskinesia in a rotenone-induced Drosophila Parkinson's disease model.194”

    The Abstract and Discussion (pages unavailable) report that sodium butyrate improved rotenone-induced locomotor impairment in Drosophila and was associated with higher brain dopamine levels. They do not report reduced dopaminergic-neuron degeneration in the rotenone model; the Abstract attributes that effect to sodium butyrate in a different, α-synuclein Drosophila model. The study also tested sodium butyrate, not SCFAs as a group, and measured locomotor impairment rather than dyskinesia. (LLM, conf=0.89)

  • FMT from healthy donors and butyrate administration in animal models of PD improves motor impairment and dopamine deficiency.

    “Supporting this hypothesis, growing evidence has shown that FMT from healthy donors (171) as well as butyrate administration in animal models of PD improves motor impairment and dopamine deficiency (172–175).”
  • Sodium butyrate treatment ameliorates motor symptoms in a Drosophila rotenone-induced Parkinson's disease model.

    “The NaB treatment ameliorates motor symptoms in a Drosophila rotenone-induced PD model [43].”

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.
