In the human body, FA is a product of various metabolic pathways and participates in one-carbon cycle, which provides carbon for the synthesis and modification of bio-compounds, such as DNA, RNA, and amino acids. Endogenous FA plays a role in epigenetic regulation, especially in the methylation and demethylation of DNA, histones, and RNA. Recently, epigenetic alterations associated with FA dysmetabolism have been considered as one of the important features in age-related cognitive impairment (ARCI), suggesting the potential of using FA as a diagnostic biomarker of ARCI. Notably, FA plays multifaceted roles, and, at certain concentrations, it promotes cell proliferation, enhances memory formation, and elongates life span, effects that could also be involved in the aetiology of ARCI. Further investigation of and the regulation of the epigenetics landscape may provide new insights about the aetiology of ARCI and provide novel therapeutic targets.<\/jats:p>","DOI":"10.3390\/genes12060913","type":"journal-article","created":{"date-parts":[[2021,6,14]],"date-time":"2021-06-14T10:30:25Z","timestamp":1623666625000},"page":"913","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":41,"title":["Formaldehyde and De\/Methylation in Age-Related Cognitive Impairment"],"prefix":"10.3390","volume":"12","author":[{"given":"Ting","family":"Li","sequence":"first","affiliation":[{"name":"Bayannur Hospital, Bayannur 015000, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yan","family":"Wei","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Brain and Cognitive Science, Institute of Biophysics, Chinese Academy of Sciences, 15 Datun Road, Chaoyang District, Beijing 100101, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Meihua","family":"Qu","sequence":"additional","affiliation":[{"name":"Translational Medical Center, Weifang Second People\u2019s Hospital, The Second Affiliated Hospital of Weifang Medical University, Weifang 261041, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lixian","family":"Mou","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Brain and Cognitive Science, Institute of Biophysics, Chinese Academy of Sciences, 15 Datun Road, Chaoyang District, Beijing 100101, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Junye","family":"Miao","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Brain and Cognitive Science, Institute of Biophysics, Chinese Academy of Sciences, 15 Datun Road, Chaoyang District, Beijing 100101, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mengqi","family":"Xi","sequence":"additional","affiliation":[{"name":"School of Life Sciences, Beijing University of Chinese Medicine, Beijing 102488, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ying","family":"Liu","sequence":"additional","affiliation":[{"name":"School of Life Sciences, Beijing University of Chinese Medicine, Beijing 102488, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rongqiao","family":"He","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Brain and Cognitive Science, Institute of Biophysics, Chinese Academy of Sciences, 15 Datun Road, Chaoyang District, Beijing 100101, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2021,6,13]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"312","DOI":"10.1016\/j.cell.2019.09.001","article-title":"Alzheimer Disease: An Update on Pathobiology and Treatment Strategies","volume":"179","author":"Long","year":"2019","journal-title":"Cell"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"105","DOI":"10.2174\/092986650602221108163847","article-title":"Effect of acetaldehyde on aggregation of neuronal tau","volume":"6","author":"Luo","year":"1999","journal-title":"Protein Pept.
