This study provides the first direct evidence in a human model that transcription across the PWS-SRO is necessary but not sufficient for de novo DNA methylation, and suggests differentiation-dependent cues, potentially resembling aspects of the oocyte environment, are required.
DNA methylation regulates transcription, yet the demethylation of canonical elements like promoter CpG islands exhibits inconsistent correlations with gene activation. We hypothesize that causal regulatory elements are defined by biophysical hypersensitivity. Profiling 24 whole-genome bisulfite sequencing samples acros...

Genomic imprinting is an epigenetic process causing parent-of-origin specific gene expression. The Dlk1-Dio3 domain is one of the largest imprinted clusters. While DNA methylation at an intergenic CpG-island (IG-CGI) within the imprinting control region (ICR) controls expression from the paternal chromosome, mechanisms...

Genomic imprinting secures parent-specific gene expression through differential DNA methylation at imprinted control regions (ICRs). However, how unmethylated alleles resist de novo methylation remains unclear. Using an allelic Dlk1-Dio3 ICR methylation reporter and genome-wide loss-of-function screening, we identify t...
SunTag-NOVA robustly installed DNA methylation and repressed transcription at the endogenous FWA, FT and TMM genes with minimal genome-wide off-target consequences, and establishes SunTag-NOVA as a specific epigenome-editing platform for plants.

KLF14 acts as a master regulator of gene expression in adipose tissue and variants at the human KLF14 gene show reproducible association with type 2 diabetes and metabolic syndrome. Risk alleles are only pathological when maternally inherited, consistent with the observation that KLF14/Klf14 is a maternally expressed i...

Faithful maintenance of allele-specific methylation at imprinting control regions (ICR) is essential for genomic imprinting. Using transgenic mice (TgM), we investigated sequence requirements for paternal methylation acquisition and maternal hypomethylation maintenance during early embryogenesis. We previously show...
