Here, the authors show that histone serine-ADP-ribosylation is decreased in Alzheimer’s disease brains and increased tyrosine levels deplete tyrosyl-tRNA synthetase levels and cause neuronal damage. Cis-resveratrol was shown to facilitate histone serine-ADP-ribosylation-dependent DNA repair and provides neuroprotection, while trans-resveratrol induces neurodegeneration in rat cortical neurons.
