underlying mechanisms remain unknown. As methionine can alter S-adenosylmethionine
(SAM) and S-adenosylhomocysteine (SAH), the substrate and product of DNA
methyltransferase-1 (DNMT1), we hypothesized that MR diet alters DNA methylation. Young
(8-week-old) and adult (1-year-old) male C57BL/6J mice were fed diets with different levels
of methionine (0.12%-MR, 0.84%-CD) for 12 weeks. Functional indicators of DNA …
