DNA methylation's role in development, aging, and disease has evolved, with a decade of breakthroughs in epigenetics! PMID:39134824, Nat Rev Genet 2024, @NatureRevGenet doi.org/10.1038/s41576-024-00760-8 #Medsky #Pharmsky #RNA #ASHG #ESHG 🧪

DNA methylation in mammalian development and disease | Nature Reviews Genetics
The DNA methylation field has matured from a phase of discovery and genomic characterization to one seeking deeper functional understanding of how this modification contributes to development, ageing and disease. In particular, the past decade has seen many exciting mechanistic discoveries that have substantially expanded our appreciation for how this generic, evolutionarily ancient modification can be incorporated into robust epigenetic codes. Here, we summarize the current understanding of the distinct DNA methylation landscapes that emerge over the mammalian lifespan and discuss how they interact with other regulatory layers to support diverse genomic functions. We then review the rising interest in alternative patterns found during senescence and the somatic transition to cancer. Alongside advancements in single-cell and long-read sequencing technologies, the collective insights made across these fields offer new opportunities to connect the biochemical and genetic f

A study in Nature Communications shows that prenatal phthalate exposure alters newborn metabolite profiles, particularly in tyrosine and tryptophan pathways, which are associated with infant neurobehavioral outcomes. go.nature.com/4cgIPnw 🧪
This is figure 3, which shows sankey plots illustrating associations between phthalate exposure, metabolite perturbations, and NICU Neonatal Neurobehavioral Scale (NNNS) outcomes at two visits.

Construction of an atlas of transcription factor binding during mouse development identifies popular regulatory regions Read this Techniques & Resources Article by @annanordin.bsky.social @gianlucazamba.bsky.social @claudiocantu81.bsky.social & co.: doi.org/10.1242/dev....
Figure 1 TFBomics of the E11.5 mouse embryo. (A) Schematic overview of the experimental design, detailing the tissues dissected from E11.5 JAX/Swiss mice and the targets profiled in each tissue using C&R LoV-U. (B) Left: Clustering of data according to Spearman's correlation. Black boxes highlight higher correlation or clustering according to the profiled factor, whereas red boxes highlight this between factors within the same tissue. IgG negative controls are highlighted in a gray box. Right: Overall data patterns shown by PCA. PC1 (58.7% of variance) separated some samples by the target factor (ellipses shaded by factor color code), while PC2 (9.7% of variance) typically separates the liver (marked with stars) from other tissues.
