Web7 sept. 2024 · Upon recognizing RNA m 6 A, FXR1 recruits TET1 to genomic loci to demethylate DNA, leading to reprogrammed chromatin accessibility and gene transcription. Therefore, we have characterized a regulatory mechanism of chromatin accessibility and gene transcription mediated by RNA m 6 A formation coupled with DNA demethylation, ... WebPurified RNA was then analyzed by RT-qPCR using MeRIP m6A peak primers for Myc, Sox2, Nanog, Klf4, and Oct4. PCR primer sequences for mouse reprograming genes were provided by Howard Chang (Stanford University). Human PCR primers were designed from published MeRIP-Seq data.
