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

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 ...

Antiangiogenic immunotherapy suppresses desmoplastic and chemoresistant intestinal tumors in mice

Matthias Lütolf, Michele De Palma, Mario Leonardo Squadrito, Mauro Delorenzi, Sina Nassiri, Alan Nicolas Thierry Guichard, Nikolche Gjorevski, Simone Ragusa, Borja Prat Luri, Laureline Wetterwald

Mutations in APC promote colorectal cancer (CRC) progression through uncontrolled WNT signaling. Patients with desmoplastic CRC have a significantly worse prognosis and do not benefit from chemotherapy, but the mechanisms underlying the differential respon ...

Mutations in Bcl9 and Pygo genes cause congenital heart defects by tissue-specific perturbation of Wnt/beta-catenin signaling

Michel Aguet

Bcl9 and Pygopus (Pygo) are obligate Wnt/beta-catenin cofactors in Drosophila, yet their contribution to Wnt signaling during vertebrate development remains unresolved. Combining zebrafish and mouse genetics, we document a conserved, beta-catenin-associate ...

Mutant CTNNB1 and histological heterogeneity define metabolic subtypes of hepatoblastoma

Olivier Michielin, Etienne Meylan, Paolo Angelino, Mauro Delorenzi, Jessica Christine Vazquez, Pierre-Benoit Bernard Ancey, Stefania Crippa

Hepatoblastoma is the most common malignant pediatric liver cancer. Histological evaluation of tumor biopsies is used to distinguish among the different subtypes of hepatoblastoma, with fetal and embryonal representing the two main epithelial components. W ...

Phage selection of peptide macrocycles against b-catenin to interfere with Wnt signaling

Christian Heinis, Jörg Hülsken, Pierre Vincent Dessen, Davide Bertoldo, Maola Khan Mohammad Golam

Upregulation of b-catenin, the primary mediator of the Wnt signaling pathway, plays an important role in the tumorigenesis of several types of human cancer. Targeting b-catenin to interfere with its ability to serve as a translational co-activator is consi ...

CL9/9L-beta-catenin Signaling is Associated With Poor Outcome in Colorectal Cancer

Michel Aguet, Patrick Rodriguez, Mauro Delorenzi, Norbert Wiedemann, Pascale Anderle Pedone, Andreas Eduard Moor, Sylvie André Baflast, Frédérique Baruthio

BCL9/9L proteins enhance the transcriptional output of the beta-catenin/TCF transcriptional complex and contribute critically to upholding the high WNT signaling level required for stemness maintenance in the intestinal epithelium. Here we show that a BCL9 ...

The Bcl9-beta-catenin interface as a potential therapeutic target for colorectal cancer

Andreas Eduard Moor

Aberrantly active Wnt signaling is the hallmark driver of colorectal cancer (CRC). Bcl9/9l proteins are components of the main transcriptional activation complex of canonical Wnt signaling and interact with beta-catenin via a highly conserved homology doma ...

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 ...

Identification of MAGI1 as a tumor-suppressor protein induced by cyclooxygenase-2 inhibitors in colorectal cancer cells

Cyclooxyganase-2 (COX-2), a rate-limiting enzyme in the prostaglandin synthesis pathway, is overexpressed in many cancers and contributes to cancer progression through tumor cell-autonomous and paracrine effects. Regular use of non-steroidal anti-inflammat ...

β-catenin represses expression of the tumour suppressor 15-prostaglandin dehydrogenase in the normal intestinal epithelium and colorectal tumour cells

Jörg Hülsken, Paloma Ordonez Moran

BACKGROUND: Cyclooxygenase-2 (COX-2) overexpression in colorectal cancer increases levels of its pro-tumorigenic product prostaglandin E2 (PGE(2)). The recently identified colorectal tumour suppressor 15-prostaglandin dehydrogenase (15-PGDH) catalyses pros ...

The Intestinal Nuclear Receptor Signature With Epithelial Localization Patterns and Expression Modulation in Tumors

Johan Auwerx, Kristina Schoonjans

BACKGROUND & AIMS: The WNT-adenomatous polyposis coli system controls cell fate in the intestinal epithelium, where compartment-specific genes tightly regulate proliferation, migration, and differentiation. Nuclear receptors are transcription factors funct ...

The prolyl-aminodipeptidases and their inhibitors as therapeutic targets for fibrogenic disorders

Sandrine Gerber

Many biologically active peptides are protected from general proteolytic degradation by evolutionary conserved prolines (Pro), due to conformational constraints imposed by the Pro residue. Thus the biological importance of prolyl-specific peptidases points ...

Phosphorylation does not prompt, nor prevent, the formation of alpha-synuclein toxic species in a rat model of Parkinson's disease

Michaël Unser, Patrick Aebischer, Daniel Sage, Bernard Schneider, Samareh Azeredo da Silveira Lajaunias

Phosphorylation is involved in numerous neurodegenerative diseases. In particular, alpha-synuclein is extensively phosphorylated in aggregates in patients suffering from synucleinopathies. However, the share of this modification in the events that lead to ...

Epithelial Pten is dispensable for intestinal homeostasis but suppresses adenoma development and progression after Apc mutation

PTEN acts as a tumor suppressor in a range of tissue types and has been implicated in the regulation of intestinal stem cells. To study Pten function in the intestine, we used various conditional transgenic strategies to specifically delete Pten from the m ...

Notch signaling is required for exocrine regeneration after acute pancreatitis

Freddy Radtke

BACKGROUND & AIMS: The mechanisms for tissue regeneration and renewal after acute pancreatitis are not well understood but may involve activation of Notch signaling. To study the effect of Notch signaling ablation during acute experimental pancreatitis, we ...

Differential requirement for beta-catenin in epithelial and fiber cells during lens development

Jörg Hülsken

Recent studies implicate Wnt/beta-catenin signaling in lens differentiation (Stump, R. J., et al., 2003. A role for Wnt/beta-catenin signaling in lens epithelial differentiation. Dev Biol;259:48-61). Beta-catenin is a component of adherens junctions and fu ...

Unique mechanisms of growth regulation and tumor suppression upon Apc inactivation in the pancreas

Beta-catenin signaling is heavily involved in organogenesis. Here, we investigated how pancreas differentiation, growth and homeostasis are affected following inactivation of an endogenous inhibitor of beta-catenin, adenomatous polyposis coli (Apc). In adu ...

Pancreas-specific deletion of beta-catenin reveals Wnt-dependent and Wnt-independent functions during development

Jörg Hülsken, Anne Grapin-Botton

Mutations and deregulation of adenomatous polyposis coli (APC) and beta-catenin are implicated in specific cancers of the pancreas, but the role of Wnt pathway in normal pancreas development and homeostasis is unknown [1-4]. This article reports a comprehe ...
