Did you know?
LINE1 (also L1 and LINE-1) is a family of related class I transposable elements in the DNA of some organisms, classified with the long interspersed nuclear elements (LINEs). L1 transposons comprise approximately 17% of the human genome. The majority of these are inactive, though about 80–100 have retained the ability to retrotranspose, with considerable variation between individuals. T… NettetMethylation is a two-step process ( Scheme 8.53 ). First the methyl-transferring coenzyme, S-adenosylmethionine (SAM, 8.182 ), is biosynthesized mostly from …

Nettet7. sep. 2008 · LINE-1 methylation levels vary among locations and cell types. Our previous study showed that genome-wide LINE-1 methylation levels can be significantly different among normal tissue types ( 4). Moreover, some tissues, such as the thyroid and esophagus, demonstrated wider ranges in the methylation level.
