However, <span class=\"span-orange\">more than two-thirds of individuals diagnosed with behavioral or mental disorders exhibit a methylation imbalance<\/span>. Methylation status is established during the first few months of in-utero development and typically persists throughout life. There are four primary types of methylation reactions essential to human life:<\/p>\n<p>[\/vc_column_text][vc_column_text single_style=&#8221;&#8221;]<\/p>\n<ol class=\"mr-left-ol-40\">\n<li><strong>Methylation of Atoms:<\/strong> An important reaction in humans is the <em><strong>methylation of metals<\/strong><\/em>, such as mercury and other toxic metals, which impacts their availability to the brain and other organs and influences the rate of excretion from the body.<\/li>\n<li><strong>Methylation of Molecules:<\/strong> Hundreds of biochemical reactions involve the donation of <em><strong>a methyl group to a molecule<\/strong><\/em>, often facilitated by a <em><strong>methyltransferase enzyme<\/strong><\/em>. For instance, methylation of amino acids is crucial for producing various proteins in the body (see <strong>Figure 1<\/strong>).<\/li>\n<li><strong>DNA Methylation:<\/strong> Gene expression within cells is regulated by methylation at specific cytosine sites along the DNA double-helix molecule. <em><strong>This reaction primarily occurs at CpG sites, where a guanine residue is adjacent to cytosine, connected by a phosphorous atom<\/strong><\/em>. CpG methylation generally inhibits gene expression, affecting the rate of protein synthesis in individual cells and tissues.<\/li>\n<li><strong>Methylation of Histone Proteins:<\/strong> Gene expression is also regulated through the <em><strong>methylation or acetylation of histones<\/strong><\/em>, the proteins that support fragile DNA strands in the cell nucleus. Histone methylation usually compacts the DNA, restricting the access of transcription factors necessary for gene expression. However, methylation at certain histone sites can promote gene expression (see <strong>Figure 2<\/strong>).<\/li>\n<\/ol>\n<p>[\/vc_column_text][vc_single_image image=&#8221;6450&#8243; img_size=&#8221;full&#8221;][vc_column_text single_style=&#8221;&#8221;]<\/p>\n<p class=\"p-mr-bottom-10\"><strong>Figure 2. Histone modifications.<\/strong> Illustration depicting histone modifications, including <em><strong>methylation, acetylation, phosphorylation, ubiquitination, and sumoylation. (1) Histone Methylation:<\/strong><\/em> The addition of <em><strong>methyl groups<\/strong><\/em> (<strong>CH<sub>3<\/sub><\/strong>) to histone proteins, primarily at lysine (<strong>K<\/strong>) and arginine (<strong>R<\/strong>) residues, by <em><strong>histone methyltransferases<\/strong><\/em> (<strong>HMTs<\/strong>). Methylation can either activate or repress gene expression depending on the specific amino acid residue modified and the number of methyl groups added (mono-, di-, or tri-methylation). For example, tri-methylation of lysine 27 on histone H3 (<strong>H3K27me3<\/strong>) is associated with gene silencing. <em><strong>(2) Histone Acetylation:<\/strong><\/em> The addition of <em><strong>acetyl groups<\/strong><\/em> (<strong>CH<sub>3<\/sub>CO<\/strong>) to lysine (<strong>K<\/strong>) residues on histone tails by <em><strong>histone acetyltransferases<\/strong><\/em> (<strong>HATs<\/strong>). This modification neutralizes the positive charge on histones, reducing their affinity for negatively charged <strong>DNA<\/strong>, and thereby promoting a more relaxed chromatin structure that is accessible for transcription. Deacetylation by <em><strong>histone deacetylases<\/strong><\/em> (<strong>HDACs<\/strong>) reverses this process and often leads to transcriptional repression. <em><strong>(3) Histone Phosphorylation:<\/strong><\/em> The addition of <em><strong>phosphate groups<\/strong><\/em> (<strong>PO4<\/strong>) to serine (<strong>S<\/strong>), threonine (<strong>T<\/strong>), or tyrosine (<strong>Y<\/strong>) residues by kinases. Phosphorylation is associated with chromatin condensation and relaxation, and plays critical roles during cell division, DNA damage response, and transcriptional regulation. <em><strong>(4) Histone Ubiquitination:<\/strong><\/em> The attachment of <em><strong>ubiquitin<\/strong><\/em> (<em><strong>a small regulatory protein<\/strong><\/em>) to lysine (<strong>K<\/strong>) residues by <em><strong>E3 ubiquitin ligases.<\/strong><\/em> Ubiquitination can signal for histone degradation, affect nucleosome dynamics, and modulate access to DNA, thereby playing roles in gene expression regulation and DNA repair. <em><strong>(5) Histone Sumoylation:<\/strong><\/em> The addition of <em><strong>small ubiquitin-like modifier<\/strong><\/em> (<strong>SUMO<\/strong>) proteins to histones, typically linked with transcriptional repression. Sumoylation often acts antagonistically to acetylation and can influence chromatin structure and protein interactions. <em><strong>(6) Key Enzymes and Impact:<\/strong><\/em> The figure outlines the key enzymes involved in each modification, such as <em><strong>HMTs, HATs, HDACs, kinases, and ubiquitin ligases.<\/strong><\/em> It also displays the dynamic nature of histone modifications and how they influence the structure of chromatin and regulate gene expression, impacting various biological processes.
