Revealing chromatin-specific functions of histone deacylases
Beat Fierz, Carlos Moreno Yruela
Histone deacylases are erasers of Nε-acyl-lysine post-translational modifications and have been targeted for decades for the treatment of cancer, neurodegeneration and other disorders. Due to their relatively promiscuous activity on peptide substrates in v ...
2024Investigating the intra-molecular and inter-molecular effects of post-translational modifications on intrinsically disordered protein regions and structured protein regions
Post-translational modifications (PTMs) play a pivotal role in regulating protein structure, interaction, and function. Aberrant PTM patterns are associated with diseases. Moreover, individual PTMs have a complex interaction with each other, known as PTM c ...
EPFL2024Oxidative Defect Detection Within Free and Packed DNA Systems: A Quantum Mechanical/Molecular Mechanics (QM/ MM) Approach
Base excision repair enzymes (BERs) detect and repair oxidative DNA damage with efficacy despite the small size of the defects and their often only minor structural impact. A charge transfer (CT) model for rapid scanning of DNA stretches has been evoked to ...
Swiss Chemical Soc2024Substrates and Cyclic Peptide Inhibitors of the Oligonucleotide-Activated Sirtuin 7
The sirtuins are NAD+-dependent lysine deacylases, comprising seven isoforms (SIRT1-7) in humans, which are involved in the regulation of a plethora of biological processes, including gene expression and metabolism. The sirtuins share a common hydrolytic m ...
Weinheim2023Pan-cancer atlas of somatic core and linker histone mutations
Recent genomic data points to a growing role for somatic mutations altering core histone and linker histone-encoding genes in cancer. However, the prevalence and the clinical and biological implications of histone gene mutations in malignant tumors remain ...
2023Epigenetic plasticity as a signature for memory allocation
Long-lasting memories are stored in a small set of neurons scattered throughout the brain, so-called engram cells. To define a stable engram each region of the brain involved in memory storage recruits between 5 and 20 percent of excitatory neurons. In par ...
EPFL2022Class I histone deacetylases (HDAC1-3) are histone lysine delactylases
Carlos Moreno Yruela, Alexander Lund Nielsen, Di Zhang
Lysine L-lactylation [K(L-la)] is a newly discovered histone mark stimulated under conditions of high glycolysis, such as the Warburg effect. K(L-la) is associated with functions that are different from the widely studied histone acetylation. While K(L-la) ...
2022Epigenetic memory aids: Synaptic and molecular effects of HDAC inhibition that support memory formation
Learning and memory rely on synaptic communication in which intracellular signals are transported to the nucleus to stimulate transcriptional activation. Memory induced transcriptional increases are accompanied by alterations to the epigenetic landscape an ...
EPFL2022In vivo transcriptomic profiling using cell encapsulation identifies effector pathways of systemic aging
Patrick Descombes, Sylviane Métairon, Omid Mashinchian, Filippo De Franceschi, Nicolas Bouche, Christophe Boss
Sustained exposure to a young systemic environment rejuvenates aged organisms and promotes cellular function. However, due to the intrinsic complexity of tissues it remains challenging to pinpoint niche-independent effects of circulating factors on specifi ...
2022Context-dependent enhancer function revealed by targeted inter-TAD relocation
Denis Duboule, Lucille Delisle, Guillaume Andrey, Christopher Chase Bolt, Aurélie Hintermann
Here the authors show that a strong enhancer sequence can be controlled by the chromatin environment provided by a topologically associated domain (TAD) located nearby. An enhancer relocated by homologous recombination takes all the hallmarks of its new ne ...
