Imprinted genes play essential roles in development, and their allelic expression is mediated by imprinting control regions (ICRs). The Dlk1-Dio3 locus is among the few imprinted domains controlled by a paternally methylated ICR. The unmethylated maternal copy activates imprinted expression early in development through an unknown mechanism. We find that in mouse embryonic stem cells (ESCs) and in blastocysts, this function is linked to maternal, bidirectional expression of noncoding RNAs (ncRNAs) from the ICR. Disruption of ICR ncRNA expression in ESCs affected gene expression in cis, led to acquisition of aberrant histone and DNA methylation, delayed replication timing along the domain on the maternal chromosome, and changed its subnuclear localization. The epigenetic alterations persisted during differentiation and affected the neurogenic potential of the stem cells. Our data indicate that monoallelic expression at an ICR of enhancer RNA-like ncRNAs controls imprinted gene expression, epigenetic maintenance processes, and DNA replication in embryonic cells.

Attention Score in Context
Attention Score in Context
This research output has an Altmetric Attention Score of 10. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 17 August 2023.
All research outputs
#4,621,087
of 31,660,612 outputs
Outputs from Developmental Cell
#1,802
of 4,784 outputs
Outputs of similar age
#43,081
of 280,844 outputs
Outputs of similar age from Developmental Cell
#17
of 53 outputs
Altmetric has tracked 31,660,612 research outputs across all sources so far. Compared to these this one has done well and is in the 85th percentile: it's in the top 25% of all research outputs ever tracked by Altmetric.
So far Altmetric has tracked 4,784 research outputs from this source. They typically receive a lot more attention than average, with a mean Attention Score of 17.0. This one has gotten more attention than average, scoring higher than 62% of its peers.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 280,844 tracked outputs that were published within six weeks on either side of this one in any source. This one has done well, scoring higher than 84% of its contemporaries.
We're also able to compare this research output to 53 others from the same source and published within six weeks on either side of this one. This one has gotten more attention than average, scoring higher than 67% of its contemporaries.
