Genetic and epigenetic editing experiments establish causal links between transposon-derived enhancers and gene regulation in mouse embryonic and extraembryonic lineages.
Hundreds of retrovirus-like sequences have features that suggest they might be gene enhancers, but only a small fraction displays gene-regulating activity in experiments on mouse stem cells.

Unloading the polymerase sliding clamp PCNA from DNA by Elg1 promotes recombination at the RTS1 replication fork barrier by limiting Fbh1 and Srs2 activity.
The chromatin remodeler and tumor suppressor SMARCB1 acts to restrict superenhancer function to direct neural differentiation of embryonic stem cells while repressing bivalent gene activity in the pluripotent state.
Sox2 transcription is not correlated with spatial proximity of its essential regulatory enhancer in embryonic stem cells, suggesting gene transcription is not limited to periods of direct enhancer-promoter contact.

Establishment of replication-timing involves Fkh1-dependent recruitment and execution of DDK function in G1 phase resulting in dynamic relocalization of origins within the nucleus in anticipation of CDK-dependent origin activation.
The heme and HRI-mediated eIF2aP–ATF4 integrated stress response in erythropoiesis has a major global impact, especially under the stress condition of iron deficiency.

Genomic-profiles and reporters reveal that the three-nucleotide ‘words’ read by the ribosome, codons, have a strong effect on mRNA stability, impacting the homeostatic mRNA and protein levels in human cells.
