Neurogenesis redirects β-catenin from adherens junctions to the nucleus to promote axonal growth

Here, we show that, in the developing spinal cord, after the early Wnt-mediated Tcf transcription activation that confers dorsal identity to neural stem cells, neurogenesis redirects beta-catenin from the adherens junctions to the nucleus to stimulate Tcfo ...

TGF beta-mediated MMP13 secretion drives myoepithelial cell dependent breast cancer progression

Cathrin Brisken, Andrea Agnoletto

Ductal carcinoma in situ (DCIS) is a non-obligate precursor of invasive breast cancer. Virtually all women with DCIS are treated, despite evidence suggesting up to half would remain with stable, non-threatening, disease. Overtreatment thus presents a press ...

Tcf1 is essential for initiation of oncogenic Notch1-driven chromatin topology in T-ALL

Freddy Radtke, Ute Koch, Nadine Fournier, Marianne Nkosi, Christelle Dubey, Mateusz Waldemar Antoszewski, Tara Kimberly Sugrue, Giovanni Ciriello

NOTCH1 is a well-established lineage specifier for T cells and among the most frequently mutated genes throughout all subclasses of T cell acute lymphoblastic leukemia (T-ALL). How oncogenic NOTCH1 signaling launches a leukemia-prone chromatin landscape du ...

Bringing Functional Context to Emerging Proximity-mapping Proteomics Tools

Yimon Aye

If one considers chemical-biology toolsets that have had the greatest impact on numerous fields of life sciences over the most recent years, proximity-labeling tools, such as APEX, and Bio-ID arguably lead the way. This article reflects upon the current st ...

The E protein-TCF1 axis controls gamma delta T cell development and effector fate

Freddy Radtke

TCF1 plays a critical role in T lineage commitment and the development of alpha beta lineage T cells, but its role in gamma delta T cell development remains poorly understood. Here, we reveal a regulatory axis where T cell receptor (TCR) signaling controls ...

Yes-Associated Protein Is Required for ZO-1-Mediated Tight-Junction Integrity and Cell Migration in E-Cadherin-Restored AGS Gastric Cancer Cells

Yes-associated protein (YAP) regulates numerous cellular homeostasis processes and malignant transformation. We found that YAP influences ZO-1-mediated cell migration using E-cadherin-restored EC96 cells derived from gastric malignant AGS cells. Ectopic ex ...

Cys-Cys and Cys-Lys Stapling of Unprotected Peptides Enabled by Hypervalent Iodine Reagents

Jérôme Waser, Christian Heinis, Gontran Sangouard, Elija Grinhagena

Easy access to a wide range of structurally diverse stapled peptides is crucial for the development of inhibitors of protein-protein interactions. Herein, we report bis-functional hypervalent iodine reagents for two-component cysteine-cysteine and cysteine ...

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 ...

Antiangiogenic immunotherapy suppresses desmoplastic and chemoresistant intestinal tumors in mice

Matthias Lütolf, Michele De Palma, Alan Nicolas Thierry Guichard, Mauro Delorenzi, Mario Leonardo Squadrito, Sina Nassiri, 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 ...

Characterization of the Renin-Angiotensin System in Aged Cavernosal Tissue and its Role in Penile Fibrosis

Nikolaos Stergiopoulos, Mikaël Nils Sturny, Fabiana Pereira Da Costa Fraga, Maiia Bragina, Babak Ebadi Shirmard

Background: The renin-angiotensin system (RAS) plays an important role in erectile function. The RAS contains 2 major axes: one deleterious, composed of ACE-Ang II-AT1 receptor, and another protective, composed of ACE2-Ang-(1-7)-Mas receptor. While aging i ...
