Abstract

Neurodegenerative disorders, including Amyotrophic Lateral Sclerosis (ALS), have been associated to alterations in chromatin structure resulting in long-lasting changes in gene expression. ALS is predominantly a sporadic disease and environmental triggers may be involved in its onset. In this respect, alterations in the epigenome can provide the key to transform the genetic information into phenotype. In this paper, we demonstrate that two modifications associated with transcriptional activation, namely dimethylation of lysine 4 on H3 tail (H3K4me2) and phospho-acetylation of serine 10 and lysine 14 on H3 tail (H3K14ac-S10ph), and two modifications associated to transcriptional repression, namely trimethylation of lysine 9 on H3 tail (H3K9me3) and DNA methylation are selectively altered in cellular and animal model of ALS. These results reinforce the idea that epigenetic therapy may represent a potential and attractive approach for ALS treatment.
