HDAC4 Reduction: A Novel Therapeutic Strategy to Target Cytoplasmic Huntingtin and Ameliorate Neurodegeneration

Histone deacetylase (HDAC) 4 is a transcriptional repressor that contains a glutamine-rich domain. We hypothesised that it may be involved in the molecular pathogenesis of Huntington's disease (HD), a protein-folding neurodegenerative disorder caused by an ...

The Pygo2-H3K4me2/3 interaction is dispensable for mouse development and Wnt signaling-dependent transcription

Michel Aguet

Pygopus has been discovered as a fundamental Wnt signaling component in Drosophila. The mouse genome encodes two Pygopus homologs, Pygo1 and Pygo2. They serve as context-dependent beta-catenin coactivators, with Pygo2 playing the more important role. All P ...

KRAB/KAP1 Regulation of Embryonic Stem Cell Pluripotent Self-renewal

Andrea Corsinotti

KRAB-ZFPs constitute the largest family of transcription factors (TFs) encoded by the mouse genome and are known to interact with the co-repressor KAP1. KRAB/KAP1-mediated regulation is essential for several development- and ESC- specific functions, in par ...

The Corepressor NCoR1 Antagonizes PGC-1α and Estrogen-Related Receptor α in the Regulation of Skeletal Muscle Function and Oxidative Metabolism

Johan Auwerx

Skeletal muscle exhibits a high plasticity and accordingly can quickly adapt to different physiological and pathological stimuli by changing its phenotype largely through diverse epigenetic mechanisms. The nuclear receptor corepressor 1 (NCoR1) has the abi ...

Studies on KRAB/KAP1-Mediated Transcriptional Repression

Anna Claire Groner

The sequencing of the human genome revealed that the C2H2-zinc finger proteins (ZFPs) are the largest family of human transcription factors. Around 300 members of this family contain, in addition to their zinc finger motifs, a KRAB domain that has been imp ...

Altered Expression of the Transcription Factor Mef2c during Retinal Degeneration in Rpe65(-/-) Mice

Pascal Escher

PURPOSE. To investigate the role of the myocyte enhancer factor 2 (Mef2) transcription factor family in retinal diseases, Mef2c expression was assessed during retinal degeneration in the Rpe65(-/-) mouse model of Leber's congenital amaurosis (LCA). Mef2c-d ...

Genomic Context and KRAB/KAP1-mediated Transcriptional Repression

Sylvain Meylan

Chromatin structure and its impact on transcriptional activity represent one of the major revolutions in the biomedical field over the passed decade. The implications concern as much fundamental as clinically-oriented research; diseases and therapeutical s ...

KAP1 controls endogenous retroviruses in embryonic stem cells

Didier Trono, Daniel Constam, Séverine Reynard, Jacques Rougemont, Sonia Verp, Hillary Layard-Liesching, Helen Mary Rowe, Johan Jakobsson, Pierre Maillard

More than forty per cent of the mammalian genome is derived from retroelements, of which about one-quarter are endogenous retroviruses (ERVs). Some are still active, notably in mice the highly polymorphic early transposon (ETn)/MusD and intracisternal A-ty ...

KRAB-Zinc Finger Proteins and KAP1 Can Mediate Long-Range Transcriptional Repression through Heterochromatin Spreading

Didier Trono, Giovanna Ambrosini, Nadine Fournier, Philipp Bucher, Anna Claire Groner, Nicolas Dénervaud, Sylvain Meylan

Krüppel-associated box domain-zinc finger proteins (KRAB-ZFPs) are tetrapod-specific transcriptional repressors encoded in the hundreds by the human genome. In order to explore their as yet ill-defined impact on gene expression, we developed an ectopic rep ...
