DNA damage signaling and repair take place in a chromatin context. Consequently, chromatin-modifying enzymes, including adenosine triphosphate-dependent chromatin remodeling enzymes, play an important role in the management of DNA double-strand breaks (DSBs). Here, we show that the p400 ATPase is required for DNA repair by homologous recombination (HR).(More)
During differentiation, thousands of genes are repositioned toward or away from the nuclear envelope. These movements correlate with changes in transcription and replication timing. Using synthetic (TALE) transcription factors, we found that transcriptional activation of endogenous genes by a viral trans-activator is sufficient to induce gene repositioning(More)
The p400 E1A-associated protein, which mediates H2A.Z incorporation at specific promoters, plays a major role in cell fate decisions: it promotes cell cycle progression and inhibits induction of apoptosis or senescence. Here, we show that p400 expression is required for the correct control of ROS metabolism. Depletion of p400 indeed increases intracellular(More)
Cancer progression is associated with epigenetic alterations, such as changes in DNA methylation, histone modifications or variants incorporation. The p400 ATPase, which can incorporate the H2A.Z variant, and the Tip60 histone acetyltransferase are interacting chromatin-modifying proteins crucial for the control of cell proliferation. We demonstrate here(More)
