RNA-mediated transcriptional silencing prevents deleterious effects of transposon activity and controls the expression of protein-coding genes. It involves long non-coding RNAs (lncRNAs)1, which in Arabidopsis thaliana are produced by a specialized RNA Polymerase V (Pol V)2. lncRNAs guide Argonaute-...

Histone acetylation and deacetylation are among the principal mechanisms by which chromatin is regulated during transcription, DNA silencing, and DNA repair. We analyzed patterns of genetic interactions uncovered during comprehensive genome-wide analyses in yeast to probe how histone acetyltransfera...

Emerging evidence suggests that chromatin adopts a non-random three-dimensional (3D) topology and that the organization of genes into structural hubs and domains affects their transcriptional status. How chromatin conformation changes in diseases such as cancer is poorly understood. Moreover, how on...

HUVECs were stimulated and samples were prepared after 0 and 30 min. Chromatin interaction mediated by active RNA polymerase II was detected by ChIA-PET. Samples were made afrer 0 and 30 min after TNF alpha stimulation.

A cascade of histone acetylation events with subsequent incorporation of a histone H2A variant plays an essential part in transcription regulation in various model organisms. A key player in this cascade is the chromatin remodellling complex SWR1, which replaces the canonical histone H2A with its va...

The human mixed lineage leukemia 5 (MLL5) protein mediates hematopoietic cell homeostasis, cell cycle and survival, however, the molecular basis underlying MLL5 activities remains unknown. Here, we show that MLL5 is recruited to gene-rich euchromatic regions via the interaction of its PHD finger wit...
