These advances have influenced much interest in understanding the dysregulation of epigenetic mechanisms in neurodegenerative disorders. Although these disorders diverge in their fundamental causes and pathophysiology, several involve the dysregulation of histone methylation-mediated gene expression. Interestingly, epigenetic remodeling via histone methylation in specific brain regions has been suggested to play a critical function in the neurobiology of psychiatric disorders, including that related to neurodegenerative diseases. Prominently, epigenetic dysregulation currently brings considerable interest as an essential player in neurodegenerative disorders, such as Alzheimer\u2019s disease (AD), Parkinson\u2019s disease (PD), Huntington\u2019s disease (HD), Amyotrophic lateral sclerosis (ALS) and drugs of abuse, including alcohol abuse disorder, where it may facilitate connections between genetic and environmental risk factors or directly influence disease-specific pathological factors. We have discussed the current state of histone methylation, therapeutic strategies, and future perspectives for these disorders. While not somatically heritable, the enzymes responsible for histone methylation regulation, such as histone methyltransferases and demethylases in neurons, are dynamic and reversible. They have become promising potential therapeutic targets to treat or prevent several neurodegenerative disorders. These findings, along with clinical data, may provide links between molecular-level changes and behavioral differences and provide novel avenues through which the epigenome may be targeted early on in people at risk for neurodegenerative disorders.<\/jats:p>","DOI":"10.3390\/ijms22094654","type":"journal-article","created":{"date-parts":[[2021,4,28]],"date-time":"2021-04-28T10:41:58Z","timestamp":1619606518000},"page":"4654","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":99,"title":["Histone Methylation Regulation in Neurodegenerative Disorders"],"prefix":"10.3390","volume":"22","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4429-8078","authenticated-orcid":false,"given":"Balapal S.","family":"Basavarajappa","sequence":"first","affiliation":[{"name":"Division of Analytical Psychopharmacology, Nathan Kline Institute for Psychiatric Research, Orangeburg, NY 10962, USA"},{"name":"New York State Psychiatric Institute, New York, NY 10032, USA"},{"name":"Department of Psychiatry, College of Physicians &amp; Surgeons, Columbia University, New York, NY 10032, USA"},{"name":"New York University Langone Medical Center, Department of Psychiatry, New York, NY 10016, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shivakumar","family":"Subbanna","sequence":"additional","affiliation":[{"name":"Division of Analytical Psychopharmacology, Nathan Kline Institute for Psychiatric Research, Orangeburg, NY 10962, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2021,4,28]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"624","DOI":"10.1111\/jnc.14098","article-title":"Endocannabinoid system in neurodegenerative disorders","volume":"142","author":"Basavarajappa","year":"2017","journal-title":"J.
