Mechanistic description
Polycomb-to-Trithorax Switch at Synaptic Plasticity Genes
Mechanism / pathway
- Polycomb-to-Trithorax Switch at
- neurodegeneration
Evidence for (5)
Glycinergic transmission.
Transcriptional dynamics orchestrating the development and integration of neurons born in the adult hippocampus.
c-Fos and neuronal plasticity: the aftermath of Kaczmarek's theory.
Widespread promoter methylation of synaptic plasticity genes in long-term potentiation in the adult brain in vivo.
A genetic switch for long-term memory.
Evidence against (2)
Histone bivalency is central to CNS development, but developmental chromatin logic does not directly prove a late-life neurodegenerative plasticity-gene switch failure.
Epigenetic switches in neurodevelopment are pleiotropic and context-dependent, which weakens a narrow Polycomb-to-Trithorax causal model for neurodegeneration.
