WebApr 5, 2004 · The Effect of Methyl Group Deficiency on DNA Methylation in Rodents Diets deficient in methyl group donors (choline, folate, methionine, and vitamin B 12) are associated with spontaneous and chemically induced development of hepatocellular carcinoma in rats ( 34 ). WebJun 11, 2024 · DNA methylation involves the attachment of small chemical groups called methyl groups (each consisting of one carbon atom and three hydrogen atoms) to DNA building blocks. When methyl groups are present on a gene, that gene is turned off or silenced, and no protein is produced from that gene.
