Gut microbial fatty acid isomerization modulates intraepithelial T cells
The human gut microbiome constantly converts natural products derived from the host and diet into numerous bioactive metabolites1–3. Dietary fats are essential micronutrients that undergo lipolysis to release fre...

In Vitro Reconstitution of Pseudouridylation Catalyzed by Human Box H/ACA Ribonucleoprotein Particles
Pseudouridine (Ψ) is the most common chemical modification in RNA. In eukaryotes and archaea, pseudouridine synthases, mainly guided by box H/ACA snoRNAs, convert uridine to Ψ. Ψ stabilizes RNA structure and a...

Dynamic epigenomic landscapes during early lineage specification in mouse embryos
In mammals, all somatic development originates from lineage segregation in early embryos. However, the dynamics of transcriptomes and epigenomes acting in concert with initial cell fate commitment remains poor...

Open AccessDNA methylation profiling in peripheral lung tissues of smokers and patients with COPD
Epigenetics changes have been shown to be affected by cigarette smoking. Cigarette smoke (CS)-mediated DNA methylation can potentially affect several cellular and pathophysiological processes, acute exacerbati...

Allelic reprogramming of the histone modification H3K4me3 in early mammalian development
Three papers in this issue of Nature use highly sensitive ChIP–seq assays to describe the dynamic patterns of histone modifications during early mouse embryogenesis, showing that oocytes have a distinctive epigen...

The landscape of accessible chromatin in mammalian preimplantation embryos
In mammals, extensive chromatin reorganization is essential for reprogramming terminally committed gametes to a totipotent state during preimplantation development. However, the global chromatin landscape and ...
