...cause demethylation?
Dividing cells depend on DNA methyltransferase 1 (DNMT1) to copy methylation marks...slightly smaller population, something else was also suddenly cool: DNA methylation. In 1983, Andrew Feinberg... proteins are not demethylases; they are dioxygenases that oxidize 5-methylcytosine to create rare DNA...complete DNA demethylation can be achieved by dCas9 alone, without TET (or any demethylase) fusion. This...site. So, when DNMT1 methylates the genome during DNA replication, it doesn’t methylate sites blocked by ...the original methylated strand is diluted to undetectable amounts: ergo, DNA demethylation! With optimization...optimization, this method can produce nearly 100% demethylation without the confounds inherent to dCas9-TET...
