Cover Story: DNA methylation brings balance to the stem force. DNA methylation dynamics orchestrates the normal homeostatic balance between stem cell (SC) self-renewal and differentiation. Alterations in this epigenetic mark in adult stem cells can lead to tumor initiation. The image depicts the example of an early adenomatous lesion (the “dark side”, delineated by intracellular β-catenin translocation, in grey), adjacent to healthy intestinal mucosa (the “light side” on the left). De novo methyltransferase Dnmt3b (red) is expressed in healthy SCs, and its expression becomes predominant in adenomas, reflecting tumor SC accumulation. Aberrant DNA methylation patterns may be targeted to preserve the homeostatic balance in adult SCs. View this paper

Understanding methylation dynamics in organs or tissues containing many different cell types is a challenging task that cannot be efficiently addressed by the low-depth bisulphite sequencing of DNA extracted from such sources. Here we explored the fe...

DNA methylation is an important epigenetic mark involved in gene regulation and silencing of transposable elements. The presence or absence of DNA methylation at specific sites can influence nearby gene expression and cause phenotypic changes that re...

First identified 20 years ago as an RNA polymerase II-associated putative histone acetyltransferase, the conserved Elongator complex has since been recognized as the central player of a complex, regulated, and biologically relevant epitranscriptomic...

Currently, we have a limited understanding of mechanisms leading to systemic lupus erythematosus, but we know that genetics, environmental factors, and epigenetics contribute to the disease. One common aspect of the various environmental triggers is...
