LncRNA Ctcflos orchestrates transcription and alternative splicing in thermogenic adipogenesis

Bart Deplancke, Petra Catalina Schwalie

The recruitment of thermogenic brite adipocytes within white adipose tissue attenuates obesity and metabolic comorbidities, arousing interest in understanding the underlying regulatory mechanisms. The molecular network of brite adipogenesis, however, remai ...

Notch signaling promotes disease initiation and progression in murine chronic lymphocytic leukemia

Freddy Radtke, Jessica Sordet, Ute Koch, Nadine Fournier, Marianne Nkosi, Delphine Maude Tardivon, Mateusz Waldemar Antoszewski

NOTCH1 gain-of-function mutations are recurrent in B-cell chronic lymphocytic leukemia (B-CLL), where they are associated with accelerated disease progression and refractoriness to chemotherapy. The specific role of NOTCH1 in the development and progressio ...

Morphogenesis Guided by 3D Patterning of Growth Factors in Biological Matrices

Matthias Lütolf, Nicolas Antoine Vincent Broguiere, Riccardo Rizzo

Three-dimensional (3D) control over the placement of bioactive cues is fundamental to understand cell guidance and develop engineered tissues. Two-photon patterning (2PP) provides such placement at micro- to millimeter scale, but nonspecific interactions b ...

Modeling metabolic and signaling pathways in cancer cells

Maria Masid Barcon

Cancer is a leading cause of death in the world, and the mechanisms that underlie this disease are still not completely understood. As cancer develops and progresses, cells undergo a diversity of mutations that sustain their rapid proliferation and the eva ...

Recent Advances and Prospects in the Research of Nascent Adhesions

Aleksandra Radenovic, Ana-Suncana Smith

Nascent adhesions are submicron transient structures promoting the early adhesion of cells to the extracellular matrix. Nascent adhesions typically consist of several tens of integrins, and serve as platforms for the recruitment and activation of proteins ...

The secreted protease Adamts18 links hormone action to activation of the mammary stem cell niche

Philipp Bucher, Cathrin Brisken, Renuga Devi Rajaram, Giovanna Ambrosini, Marian Caikovski, Rachel Marcone, Céline Berthe Constantin, Dalya Ataca, Marie Shamseddin, Patrik Aouad, Csaba Ferenc László

Estrogens and progesterone control breast development and carcinogenesis via their cognate receptors expressed in a subset of luminal cells in the mammary epithelium. How they control the extracellular matrix, important to breast physiology and tumorigenes ...

Ligand Binding to the Collagen VI Receptor Triggers a Talin-to-RhoA Switch that Regulates Receptor Endocytosis

Béatrice Kunz, Françoise Gisou van der Goot Grunberg, Laurence Gouzi Abrami, Matteo Dal Peraro, Shixu Yan, Luciano Andres Abriata

Capillary morphogenesis gene 2 (CMG2/ANTXR2) is a cell surface receptor for both collagen VI and anthrax toxin. Biallelic loss-of-function mutations in CMG2 lead to a severe condition, hyaline fibromatosis syndrome (HFS). We have here dissected a network o ...

Parallel Optical Spatial Signal Processing Based on 2x2 MIMO Computational Metasurface

Romain Christophe Rémy Fleury, Ali Momeni, Amirhossein Babaee

We introduce a novel concept of Multi-Input Multi-Output (MIMO) metasurface processor with asymmetric Optical Transfer Function (OTF) which can perform spatial first-order derivation on two orthogonal distinct input signals for both TM and TE polarizations ...

A novel culture method that sustains ER alpha signaling in human breast cancer tissue microstructures

Cathrin Brisken, Georgios Sflomos

Background Estrogen receptor alpha (ER alpha) signaling is a defining and driving event in most breast cancers; ER alpha is detected in malignant epithelial cells of 75% of all breast cancers (classified as ER-positive breast cancer) and, in these cases, E ...

Development of chemical biology tools to reveal the function and organization of the silenced chromatin state

Nora Guidotti

Effector proteins are recruited to chromatin via transient interactions between their reader domains and histone post-translational modification (PTM) patterns. These interactions form signaling pathways that control gene expression or repression and which ...

Structural basis of Focal Adhesion Kinase activation on lipid membranes

Henning Paul-Julius Stahlberg, Frauke Gräter

Focal adhesion kinase (FAK) is a key component of the membrane proximal signaling layer in focal adhesion complexes, regulating important cellular processes, including cell migration, proliferation, and survival. In the cytosol, FAK adopts an autoinhibited ...

Multi-color Molecular Visualization of Signaling Proteins Reveals How C-Terminal Src Kinase Nanoclusters Regulate T Cell Receptor Activation

Juliette Griffie

Elucidating the mechanisms that controlled T cell activation requires visualization of the spatial organization of multiple proteins on the submicron scale. Here, we use stoichiometrically accurate, multiplexed, single-molecule super-resolution microscopy ...
