Peripuberty stress leads to abnormal aggression, altered amygdala and orbitofrontal reactivity and increased prefrontal MAOA gene expression

Pierre Magistretti, Maria del Carmen Sandi Perez, Didier Trono, Maria Isabel Cordero Campana, Guillaume Poirier, Anna Claire Groner, Cristina Marquez Vega

Although adverse early life experiences have been found to increase lifetime risk to develop violent behaviors, the neurobiological mechanisms underlying these long-term effects remain unclear. We present a novel animal model for pathological aggression in ...

A gene-rich, transcriptionally active environment and the pre-deposition of repressive marks are predictive of susceptibility to KRAB/KAP1-mediated silencing

Didier Trono, Giovanna Ambrosini, Jacques Rougemont, Nadine Fournier, Philipp Bucher, Adamantia Kapopoulou, Annamaria Kauzlaric, Anna Claire Groner, Sylvain Meylan

BACKGROUND: KRAB-ZFPs (Kruppel-associated box domain-zinc finger proteins) are vertebrate-restricted transcriptional repressors encoded in the hundreds by the mouse and human genomes. They act via an essential cofactor, KAP1, which recruits effectors respo ...

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 ...

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 ...

Regulation of Episomal Gene Expression by KRAB/KAP1-Mediated Histone Modifications

Didier Trono, Patrick Aebischer, Isabelle Barde, Christopher Towne, Sonia Verp, Vivianne Padrun, Anna Claire Groner

KAP1 is an essential cofactor of KRAB zinc finger proteins, a family of vertebrate-specific epigenetic repressors of largely unknown functions encoded in the hundreds by the mouse and human genomes. So far, KRAB/KAP1-mediated gene regulation has been studi ...

KAP1-mediated epigenetic repression in the forebrain modulates behavioral vulnerability to stress

Maria del Carmen Sandi Perez, Didier Trono, Maria Isabel Cordero Campana, Jean-Charles Bensadoun, Reto Bisaz, Anna Claire Groner, Johan Jakobsson

KAP1 is an essential cofactor of KRAB-zinc finger proteins, a family of vertebrate-specific epigenetic repressors of largely unknown functions encoded in the hundreds by the mouse and human genomes. Here, we report that KAP1 is expressed at high levels and ...
