Epigenetic plasticity as a signature for memory allocation

Giulia Santoni

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 ...

TBX3 acts as tissue-specific component of the Wnt/beta-catenin transcriptional complex

Michel Aguet, Andreas Eduard Moor

BCL9 and PYGO are beta-catenin cofactors that enhance the transcription of Wnt target genes. They have been proposed as therapeutic targets to diminish Wnt signaling output in intestinal malignancies. Here we find that, in colorectal cancer cells and in de ...

Mechanistic insights into AMP-activated protein kinase-dependent gene expression

Caterina Collodet

AMP-activated protein kinase (AMPK) is a fundamental enzyme that controls energy homeostasis, through orchestrating the cellular response to a reduction in energy availability. Under conditions of cellular energy stress AMPK senses the decrease in ATP leve ...

Psychotropic drug-induced genetic-epigenetic modulation of CRTC1 gene is associated with early weight gain in a prospective study of psychiatric patients

Johannes Gräff, Jose Vicente Sanchez Mut

Background: Metabolic side effects induced by psychotropic drugs represent a major health issue in psychiatry. CREB-regulated transcription coactivator 1 (CRTC1) gene plays a major role in the regulation of energy homeostasis and epigenetic mechanisms may ...

MeCP2-E1 isoform is a dynamically expressed, weakly DNA-bound protein with different protein and DNA interactions compared to MeCP2-E2

Jose Vicente Sanchez Mut

Background: MeCP2-a chromatin-binding protein associated with Rett syndrome-has two main isoforms, MeCP2-E1 and MeCP2-E2, differing in a few N-terminal amino acid residues. Previous studies have shown brain region-specific expression of these isoforms whic ...

Dynamic protein-chromatin interactions in heterochromatin and during the DNA damage response on the single molecule level

Andreas Linus Bachmann

Dynamic regulation of chromatin, a structure consisting of DNA and histone proteins, is mediated through histone post-translational modifications (PTMs) and effector proteins. HP1a and PRC2 are recruited to repressive PTMs (H3K9me3, H3K27me3) and enable he ...

The chromatin remodeling factor ISW-1 integrates organismal responses against nuclear and mitochondrial stress

Johan Auwerx, Maroun Bou Sleiman

Age-associated changes in chromatin structure have a major impact on organismal longevity. Despite being a central part of the ageing process, the organismal responses to the changes in chromatin organization remain unclear. Here we show that moderate dist ...

Identification of the ER-resident E3 ubiquitin ligase RNF145 as a novel LXR-regulated gene

Vincenzo Sorrentino

Cellular cholesterol metabolism is subject to tight regulation to maintain adequate levels of this central lipid molecule. Herein, the sterol-responsive Liver X Receptors (LXRs) play an important role owing to their ability to reduce cellular cholesterol l ...

Protein acetylation in metabolism - metabolites and cofactors

Johan Auwerx, Elena Katsyuba, Hongbo Zhang, Keir Joe Menzies

Reversible acetylation was initially described as an epigenetic mechanism regulating DNA accessibility. Since then, this process has emerged as a controller of histone and nonhistone acetylation that integrates key physiological processes such as metabolis ...

KAT2B Is Required for Pancreatic Beta Cell Adaptation to Metabolic Stress by Controlling the Unfolded Protein Response

Johan Auwerx, Hongbo Zhang

The endoplasmic reticulum (ER) unfolded protein response (UPR(er)) pathway plays an important role in helping pancreatic β cells to adapt their cellular responses to environmental cues and metabolic stress. Although altered UPR(er) gene expression appears ...

Metabolic control of muscle and muscle stem cell function

Hongbo Zhang

Skeletal muscle composed of myofibers and a small amount of muscle stem cells (MuSCs). It plays important roles in energy metabolism. Some of the key metabolites, such as NAD+ and acetyl-CoA were recently found to regulate muscle and MuSCs function. Most o ...

Screening of structurally diverse bicyclic peptide libraries by phage display

Davide Bertoldo

Bicyclic peptides are an attractive molecule format for the development of therapeutics and research tools. Our laboratory is specialized on the development of bicyclic peptide ligands by phage display. In brief, libraries of randompeptides each containing ...

GreA and GreB Enhance Expression of Escherichia coil RNA Polymerase Promoters in a Reconstituted Transcription-Translation System

Sebastian Maerkl, Zoe Newell Swank, Henrike Marie Niederholtmeyer

Cell-free environments are becoming viable alternatives for implementing biological networks in synthetic biology. The reconstituted cell-free expression system (PURE) allows characterization of genetic networks under defined conditions but its applicabili ...

Eukaryotic transcription factor binding kinetics : a single-molecule and functional study

Andrea Callegari

Transcription represents a key regulatory step in gene expression and transcription factors (TFs) are the key molecular players of this process. TFs inhibit or promote the assembly of the transcriptional machinery by binding DNA and several co-factors. Whe ...

The Genetics of Transcription Factor DNA Binding Variation

Bart Deplancke, Vincent Roland Julien Gardeux, Daniel Alpern

Most complex trait-associated variants are located in non-coding regulatory regions of the genome, where they have been shown to disrupt transcription factor (TF)-DNA binding motifs. Variable TF-DNA interactions are therefore increasingly considered as key ...

Complex regulation of CREB-binding protein by homeodomain-interacting protein kinase 2

Pierre Magistretti

CREB-binding protein (CBP) and p300 are transcriptional coactivators involved in numerous biological processes that affect cell growth, transformation, differentiation, and development. In this study, we provide evidence of the involvement of homeodomain-i ...

From polymers to gene regulation : a bottom up approach to the bacterial chromatin

Aleksandre Japaridze

DNA molecule is the fundamental component of every living organism, since it encodes the hereditary information. Although the genetic code of almost 200 species has been sequenced, the direct connection between gene sequence, DNA structure and biological f ...

TRIM33 switches off Ifnb1 gene transcription during the late phase of macrophage activation

Michele De Palma, Mario Leonardo Squadrito

Despite its importance during viral or bacterial infections, transcriptional regulation of the interferon-beta gene (Ifnb1) in activated macrophages is only partially understood. Here we report that TRIM33 deficiency results in high, sustained expression o ...

A potent and selective Sirtuin 1 inhibitor alleviates pathology in multiple animal and cell models of Huntington's disease

Protein acetylation, which is central to transcriptional control as well as other cellular processes, is disrupted in Huntington's disease (HD). Treatments that restore global acetylation levels, such as inhibiting histone deacetylases (HDACs), are effecti ...
