Differential impact of TGF beta/SMAD signaling activity elicited by Activin A and Nodal on endoderm differentiation of epiblast stem cells

Allocation of cells to an endodermal fate in the gastrulating embryo is driven by Nodal signaling and consequent activation of TGF beta pathway. In vitro methodologies striving to recapitulate the process of endoderm differentiation, however, use TGF beta ...

Molecular Regulation of Muscle Stem Cell Fate during Skeletal Muscle Regeneration and Aging

Sara Ancel

Muscle stem cells (MuSCs) are the primary source of myogenic progenitors during muscle repair and are essential for the long-term regenerative capacity of skeletal muscle. Following myofiber injury, MuSCs transition from a quiescent to an activated state, ...

In vivo transcriptomic profiling using cell encapsulation identifies effector pathways of systemic aging

Patrick Descombes, Jérome Feige, 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 ...

Premature Vertebral Mineralization in hmx1-Mutant Zebrafish

H6 family homeobox 1 (HMX1) regulates multiple aspects of craniofacial development, and mutations in HMX1 are linked to an ocular defect termed oculoauricular syndrome of Schorderet-Munier-Franceschetti (OAS) (MIM #612109). Recently, additional altered oro ...

The Transcription Factor Nfix Requires RhoA-ROCK1 Dependent Phagocytosis to Mediate Macrophage Skewing during Skeletal Muscle Regeneration

Giuliana Rossi

Macrophages (MPs) are immune cells which are crucial for tissue repair. In skeletal muscle regeneration, pro-inflammatory cells first infiltrate to promote myogenic cell proliferation, then they switch into an anti-inflammatory phenotype to sustain myogeni ...

KAP1 is an antiparallel dimer with a functional asymmetry

Didier Trono, Matteo Dal Peraro, Beat Fierz, Davide Demurtas, Louise Catherine Bryan, Maria Josefina Marcaida Lopez, Giulia Fonti, Pierre-Yves Joseph Laurent Helleboid, Alexandra Styliani Kalantzi

KAP1 (KRAB domain-associated protein 1) plays a fundamental role in regulating gene expression in mammalian cells by recruiting different transcription factors and altering the chromatin state. In doing so, KAP1 acts both as a platform for macromolecular i ...

Structural and functional characterisation of the KRAB-domain associated protein 1

Giulia Fonti

KAP1 (KRAB-domain associated protein 1) plays a fundamental role in regulating gene expression in mammalian cells by recruiting different transcription factors and altering the chromatin state. In doing so, KAP1 acts both as a platform for macromolecular i ...

Nuclear receptor corepressor 1 represses cardiac hypertrophy

Johan Auwerx, Chao Li, Jun Wang, Yuan Liu, Yan Liu, Shuai Shao, Xu Liu

The function of nuclear receptor corepressor 1 (NCoR1) in cardiomyocytes is unclear, and its physiological and pathological implications are unknown. Here, we found that cardiomyocyte-specific NCoR1 knockout (CMNKO) mice manifested cardiac hypertrophy at b ...

Beyond silence : a functional and evolutionary study of KRAB zinc finger proteins

Pierre-Yves Joseph Laurent Helleboid

Transposable elements (TEs) are genetic units capable of spreading within the genomes of their host. TEs contribute a readily recognizable 45% of the human DNA, reflecting in part their co-option for some as source of protein-coding sequences, for others a ...

KAP1 facilitates reinstatement of heterochromatin after DNA replication

Didier Trono, Suk Min Jang, Priscilla Turelli, Sandra Eloise Kjeldsen, Julien Léonard Duc, Annamaria Kauzlaric, Andrea Coluccio, Julien Paul André Pontis, Benjamin Rauwel, Geneviève Almouzni

During cell division, maintenance of chromatin features from the parental genome requires their proper establishment on its newly synthetized copy. The loss of epigenetic marks within heterochromatin, typically enriched in repetitive elements, endangers ge ...

Individual retrotransposon integrants are differentially controlled by KZFP/KAP1-dependent histone methylation, DNA methylation and TET-mediated hydroxymethylation in naïve embryonic stem cells

Didier Trono, Priscilla Turelli, Sandra Eloise Kjeldsen, Gabriela Ecco, Julien Léonard Duc, Andrea Coluccio

BACKGROUND: The KZFP/KAP1 (KRAB zinc finger proteins/KRAB-associated protein 1) system plays a central role in repressing transposable elements (TEs) and maintaining parent-of-origin DNA methylation at imprinting control regions (ICRs) during the wave of g ...

Genomic targets and molecular partners of the chromatin regulator KAP1

Annamaria Kauzlaric

KAP1 is an enigmatic regulatory protein, first described some twenty years ago, shown to be involved in multiple and diverse cellular functions. Specifically, it mediates tasks critical to cell growth and differentiation, pluripotency, apoptosis, gene sile ...

Hepatocyte Growth Factor-mediated satellite cells niche perturbation promotes development of distinct sarcoma subtypes

Andrea Ferrari, Michela Casanova

Embryonal Rhabdomyosarcoma (ERMS) and Undifferentiated Pleomorphic Sarcoma (UPS) are distinct sarcoma subtypes. Here we investigate the relevance of the satellite cell (SC) niche in sarcoma development by using Hepatocyte Growth Factor (HGF) to perturb the ...

A KAP1 phosphorylation switch controls MyoD function during skeletal muscle differentiation

Didier Trono, Marco Cassano, Evaristo Jose Planet Letschert, Suk Min Jang

The transcriptional activator MyoD serves as a master controller of myogenesis. Often in partnership with Mef2 (myocyte enhancer factor 2), MyoD binds to the promoters of hundreds of muscle genes in proliferating myoblasts yet activates these targets only ...

Transposable elements and their KRAB/KAP1 controllers broadly regulate transcription in adult human cells

Flavia Marzetta

KAP1 is a universal corepressor for the large family of KRAB-ZFP proteins that coordinates epigenetic silencing of endogenous retroelements (EREs) during early embryonic development. This process is essential not just to prevent replication of EREs, but al ...

Myogenic potential of canine craniofacial satellite cells
