The nucleosome, composed of DNA wound around eight core histone proteins (two each of H2A, H2B, H3, and H4), is the primary building block of chromatin (1). The amino-terminal tails of core histones undergo various posttranslational modifications, including acetylation, phosphorylation, methylation, and ubiquitination (2-5). These modifications occur in response to various stimuli and have a direct effect on the accessibility of chromatin to transcription factors and, therefore, gene expression (6). Glycation is an additional posttranslational modification that occurs non-enzymatically within cells, involving the condensation of monosaccharides or glycolytic by-products with lysine or arginine residues (7). Methylglyoxal (MGO), a highly reactive by-product of glycolysis, readily binds with arginine to form the product methylglyoxal-derived hydroimidazolone (MG-H) in three possible isomeric forms: MG-H1, MG-H2, and MG-H3 (8). The accumulation of MGO-glycated proteins is readily observed in aging cells, individuals with hyperglycemia or diabetes, and various types of cancer (9,10). Notably, MGO-glycated histone H3 has been shown to accumulate in breast cancer cells and patient tumors, potentially contributing to genomic instability by modifying chromatin structure (11).\n\u003cb\u003eAlternate Names\u003c\/b\u003e\nH3; H3 clustered histone 1; H3 histone family, member A; H3\/A; H31; H3C1; H3C10; H3C11; H3C12; H3C2; H3C3; H3C4; H3C6; H3C7; H3C8; H3FA; H3FB; H3FC; H3FC HIST1H3C; H3FD; H3FF; H3FH; H3FI; H3FJ; H3FK; H3FL; HIST1H3A; HIST1H3B; HIST1H3C; HIST1H3D; HIST1H3E; HIST1H3F; HIST1H3G; HIST1H3H; HIST1H3I; HIST1H3J; histone 1, H3a; histone cluster 1 H3 family member a; histone cluster 1, H3a; Histone H3; Histone H3.1; Histone H3\/a; Histone H3\/b; Histone H3\/c; Histone H3\/d; Histone H3\/f; Histone H3\/h; Histone H3\/i; Histone H3\/j; Histone H3\/k; Histone H3\/l\n\n\u003cb\u003eSpecification\u003c\/b\u003e\n\nREACTIVITY: H M","brand":"CST","offers":[{"title":"Default Title","offer_id":46800592470185,"sku":"32428V2","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/products\/cst-32428v2","provider":"Iright","version":"1.0","type":"link"}
