Mechanistic description
SIRT1 activation promotes mitophagy via PINK1/Parkin, reduces oxidative stress, and decreases DPR levels in cellular models. Marginally feasible given resveratrol’s failure in AD trials, but warrants testing with selective activators in C9-specific models.
Mechanism / pathway
- SIRT1
- neurodegeneration
Evidence for (3)
SIRT1 activator (SRT2104) extends survival in TDP-43 mice
SIRT1 overexpression reduces poly-GR toxicity in Drosophila
Resveratrol improves mitochondrial function in patient-derived motor neurons
Evidence against (3)
Resveratrol showed no cognitive benefit in AD clinical trials
SRT2104 has poor oral bioavailability and poorly characterized pharmacokinetics
Drosophila models of C9orf72 have limited translational value
