Witryna27 sie 2024 · The eutherian IGF2R imprinted domain is regulated by an antisense long non-coding RNA, Airn, which is expressed from a differentially methylated region (DMR) in mice. Airn silences two neighbouring genes, Solute carrier family 22 member 2 (Slc22a2) and Slc22a3, to establish the Igf2r imprinted domain in the mouse … WitrynaThe differentially methylated imprinting control region (ICR) region upstream of the H19 gene regulates allelic Igf2 expression by means of a methylation-sensitive chromatin insulator function. We have previously shown that maternal inheritance of mutated (three of the four) target sites for the 11-zinc finger protein CTCF leads to loss of Igf2 …

The inability of zygotic SMCHD1 to fully restore imprinted X inactivation further points to maternal SMCHD1’s role in setting up the appropriate chromatin environment during preimplantation development, a critical window of …
Witryna1 kwi 2024 · A key finding after the discovery of gDMRs was the allelic recruitment of the ‘CCCTC-binding factor’ (CTCF) to a subset of gDMRs [8, 10].This zinc-finger protein, whose DNA binding is inhibited by CpG methylation, was initially recognized for its chromatin boundary function [11, 12, 13].At the imprinted Igf2-H19 (Insulin-like …
