One-Carbon Metabolism and Alzheimer’s Disease: Focus on Epigenetics
Alzheimer's disease (AD) represents the most common form of dementia in the elderly, characterized by progressive loss of memory and cognitive capacity severe enough to interfere with daily functioning and the quality of life. Rare, fully penetrant mutations in three genes (APP, PSEN1 and PSEN2) are responsible for familial forms of the disease. However, more than 90% of AD is sporadic, likely ...
متن کاملInfluence of Metabolism on Epigenetics and Disease
Chemical modifications of histones and DNA, such as histone methylation, histone acetylation, and DNA methylation, play critical roles in epigenetic gene regulation. Many of the enzymes that add or remove such chemical modifications are known, or might be suspected, to be sensitive to changes in intracellular metabolism. This knowledge provides a conceptual foundation for understanding how muta...
متن کاملPolymorphisms in 1-carbon metabolism, epigenetics and folate-related pathologies.
Folate-mediated 1-carbon metabolism is a network of interconnected metabolic pathways necessary for the synthesis of purine nucleotides, thymidylate and the remethylation of homocysteine to methionine. Disruptions in this pathway influence both DNA synthesis and stability and chromatin methylation, and result from nutritional deficiencies and common gene variants. The mechanisms underlying fola...
متن کاملMetabolism & epigenetics
Epigenetic regulation of gene activity is of immense importance in maintaining normal and dynamic transcription profiles of practically all cells in our body. In the meantime, cells metabolize nutrients to sustain through different tasks and challenges of life. Both metabolism and gene activity respond to changes in environment. By assessing the relative abundance of certain key compounds centr...
متن کاملBridging epigenetics and metabolism
Recent research suggests that chromatin-modifying enzymes are metabolic sensors regulating gene expression. Epigenetics is linked to metabolomics in response to the cellular microenvironment. Specific metabolites involved in this sensing mechanism include S-adenosylmethionine, acetyl-CoA, alphaketoglutarate and NAD (+) . Although the core metabolic pathways involving glucose have been emphasize...
