TranscriptomicsEZH2-mediated H3K27 trimethylation mediates neurodegeneration in ataxia-telangiectasia
The symptoms of ataxia-telangiectasia (A-T) include a progressive neurodegeneration caused by ATM protein deficiency. We previously found that nuclear accumulation of histone deacetylase-4, HDAC4, contributes to this degeneration; we now report that increased histone H3K27 trimethylation (H3K27me3) ...

TranscriptomicsPolyglutamine Atrophin provokes neurodegeneration in Drosophila
Dentatorubral-pallidoluysian Atrophy (DRPLA) is a human polyQ disease caused by the expansion of a CAG strech in the atrophin-1 (at-1) gene. In all vertebrates, a second atrophin gene (at-2) is present and it encodes a related protein void of polyQ tracks. In D.melanogaster there is one conserved At...

TranscriptomicsRepeated systemic challenge with lipopolysaccharides induces dopaminergic neurodegeneration in the brain by activation of the complement-phagosome pathway
Systemic inflammatory reactions mediated by chronic infections activate microglia in the central nervous system (CNS) and have been postulated to exacerbate neurodegenerative diseases. We now demonstrate in vivo that repeated systemic challenge of mice with bacterial lipopolysaccharides (LPS) mainta...

Transcriptomicsp53 prevents neurodegeneration by regulating synaptic genes
DNA damage has been implicated in neurodegenerative disorders, including Alzheimer’s disease and other tauopathies, but the consequences of genotoxic stress to postmitotic neurons are poorly understood. Here we demonstrate that p53, a key mediator of the DNA damage response, plays a neuroprotective ...

TranscriptomicsIdentification of chemicals that mimic transcriptional changes associated with autism, brain aging and neurodegeneration
Environmental factors, including pesticides, have been linked to autism and neurodegeneration risk using retrospective epidemiological studies. Here, we sought to prospectively identify chemicals that share transcriptomic signatures with neurological disorders by exposing mouse cortical neuron-enri...

ProteomicsThe BPAN disease protein WDR45 forms condensates with Caprin-1 to regulate stress granule disassembly
Beta-propeller protein-associated neurodegeneration (BPAN) is a rare X-linked neurodegenerative disorder primarily caused by mutations in the WD repeat domain 45 (WDR45) gene. While WDR45 has traditionally been linked to autophagy, our study uncovers a previously unrecognized role for WDR45 as a cri...

ProteomicsS-nitrosation of proteins relevant to Alzheimer’s disease during early stages of neurodegeneration
Protein S-nitrosation (SNO-protein) is a post-translational modification in which a cysteine (Cys) residue is modified by nitric oxide (SNO-Cys). SNO-proteins impact many biological systems, but their identification has been technically challenging. We developed a chemical proteomic strategy - SNOTR...
