DeSUMOylation of chromatin-bound proteins limits the rapidtranscriptional reprogramming induced by daunorubicin in acute myeloidleukemias.
Boulanger M. et al.
Genotoxicants have been used for decades as front-line therapies against cancer on the basis of their DNA-damaging actions. However, some of their non-DNA-damaging effects are also instrumental for killing dividing cells. We report here that the anthracycline Daunorubicin (DNR), one of the main drugs used to treat A...

Cotranscriptional demethylation induces global loss of H3K4me2 fromactive genes in Arabidopsis
Mori S. et al.
Based on studies of animals and yeasts, methylation of histone H3 lysine 4 (H3K4me1/2/3, for mono-, di-, and tri-methylation, respectively) is regarded as the key epigenetic modification of transcriptionally active genes. In plants, however, H3K4me2 correlates negatively with transcription, and the regulatory mechan...

Cell-specific alterations inPitx1regulatory landscape activation caused bythe loss of a single enhancer
Rouco, R. et al.
Most developmental genes rely on multiple transcriptional enhancers for their accurate expression during embryogenesis. Because enhancers may have partially redundant activities, the loss of one of them often leads to a partial loss of gene expression and concurrent moderate phenotypic outcome, if any. While such a ...

Wiese, M and Hamdan, FH and Kubiak, K and Diederichs, C and Gielen, GHand Nussbaumer, G and Carcaboso, AM and Hulleman, E and Johnsen, SA andKramm, CM
Diffuse intrinsic pontine gliomas (DIPG) are the most aggressive brain tumors in children with 5-year survival rates of only 2%. About 85% of all DIPG are characterized by a lysine-to-methionine substitution in histone 3, which leads to global H3K27 hypomethylation accompanied by H3K27 hyperacetylation. Hyperacetyla...
