However, subsequent studies have shown that Ten-Eleven Translocation (TET) proteins TET1, TET2, and TET3 can catalyze the oxidation of methylated cytosine to 5-hydroxymethylcytosine (5-hmC) (5). Additionally, TET proteins can further oxidize 5-hmC to form 5-formylcytosine (5-fC) and 5-carboxylcytosine (5-caC), both of which are excised by thymine-DNA glycosylase (TDG), effectively linking cytosine oxidation to the base excision repair pathway and supporting active cytosine demethylation (6,7). Normally DNA methylation occurs in a bimodal fashion, such that CpG dinucleotides are largely methylated across the genome, except in short stretches of CpG-rich sequences associated with gene promoters, known as CpG-islands, where methylation is virtually absent (8). Cancer cell genomes often undergo global hypomethylation, while CpG-islands become hypermethylated, causing their associated promoters to become repressed (9). There is evidence that a number of aberrantly hypermethylated CpG-islands found in carcinomas occur at tumor suppressor genes such as RB1, MLH1, and BRCA1 (10).\n\n\u003cb\u003eSpecification\u003c\/b\u003e\n\nREACTIVITY: All\nSENSITIVITY: Endogenous\nSource\/Isotype: Rabbit IgG","brand":"CST","offers":[{"title":"Default Title","offer_id":46800250634409,"sku":"28692T","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/products\/cst-28692t","provider":"Iright","version":"1.0","type":"link"}
