New roles of Bicc1 in cilia formation, cell adhesion, and in adult kidneys

Céline Gagnieux

Bicaudal-C1 (Bicc1), an RNA-Binding protein, is a ciliopathy-associated protein. In development, Bicc1 is necessary for left-right axis specification. Loss of Bicc1 in mice also associates with polycystic kidney development. In human, two hereditary polycy ...

Kidney-Specific Membrane-Bound Serine Proteases CAP1/Prss8 and CAP3/St14 Affect ENaC Subunit Abundances but Not Its Activity

Simona Frateschi

The serine proteases CAP1/Prss8 and CAP3/St14 are identified as ENaC channel-activating proteases in vitro, highly suggesting that they are required for proteolytic activation of ENaC in vivo. The present study tested whether CAP3/St14 is relevant for rena ...

Context-dependent enhancer function revealed by targeted inter-TAD relocation

Denis Duboule, Lucille Delisle, Guillaume Andrey, Christopher Chase Bolt

Here the authors show that a strong enhancer sequence can be controlled by the chromatin environment provided by a topologically associated domain (TAD) located nearby. An enhancer relocated by homologous recombination takes all the hallmarks of its new ne ...

Tissue Engineering with Mechanically Induced Solid‐Fluid Transitions

Mahmut Selman Sakar, Jaemin Kim, Ece Özelçi, Erik Mailand, Nikolaos Bouklas, Matthias Rüegg

Epithelia are contiguous sheets of cells that stabilize the shape of internal organs and support their structure by covering their surfaces. They acquire diverse morphological forms appropriate for their specific functions during embryonic development, suc ...

Ultraflexible flow directed device and system

Mahmut Selman Sakar, Lucio Feo Pancaldi-Giubbini, Pietro Luciano Jakobus Dirix

A flow directed device adapted to be guided by a fuid, such as blood, flow within a tubular structure such as a blood vessel is disclosed, said device comprising a proximal end (100), a distal end (101) and an elongated body (102) in between defining a lon ...

Mesomelic dysplasias associated with the HOXD locus are caused by regulatory reallocations

Denis Duboule, Lucille Delisle, Christopher Chase Bolt

Mesomelic dysplasia, a severe shortening and bending of the limb, has been linked to rearrangements in the HoxD cluster in humans and mice. Here the authors engineer a 1 Mb inversion including the HoxD gene cluster and use this model to provide a mechanist ...

Role of the RNA-binding protein Bicaudal-C1 and interacting factors in cystic kidney diseases

Daniel Constam, Benjamin Marcel Daniel Rothé, Lucía Carolina Leal Esteban, Céline Gagnieux

Polycystic kidneys frequently associate with mutations in individual components of cilia, basal bodies or centriolar satellites that perturb complex protein networks. In this review, we focus on the RNA-binding protein Bicaudal-C1 (BICC1) which was found m ...

Protease-activation using anti-idiotypic masks enables tumor specificity of a folate receptor 1-T cell bispecific antibody

Henning Paul-Julius Stahlberg

T-cell bispecific antibodies (TCBs) crosslink tumor and T-cells to induce tumor cell killing. While TCBs are very potent, on-target off-tumor toxicity remains a challenge when selecting targets. Here, we describe a protease-activated anti-folate receptor 1 ...

Renal tubular arginase-2 participates in the formation of the corticomedullary urea gradient and attenuates kidney damage in ischemia-reperfusion injury in mice

Hikari Ananda Infinity Yoshihara, Dmitri Firsov

Aim Arginase 2 (ARG2) is a mitochondrial enzyme that catalyses hydrolysis ofl-arginine into urea andl-ornithine. In the kidney, ARG2 is localized to the S3 segment of the proximal tubule. It has been shown that expression and activity of this enzyme are up ...

Cell-specific image-guided transcriptomics identifies complex injuries caused by ischemic acute kidney injury in mice

Elena Goun, Pavlo Khodakivskyi

The kidney's inherent complexity has made identifying cell-specific pathways challenging, particularly when temporally associating them with the dynamic pathophysiology of acute kidney injury (AKI). Here, we combine renal cell-specific luciferase reporter ...

Tip connector for fluidic and electrical connection

Philippe Renaud, Yann Barrandon, Jean-Baptiste Bureau, David Vincent Bonzon, Georges Muller, David Forchelet, Nicolas Uffer

A connector for providing both a fluidic and electrical connection is disclosed, said connector having a proximal end, a distal end and an elongated body in between, characterized in that the elongated body has an inner cavity spanning throughout its lengt ...

Anti-fibrotic effect of ketoprofen-grafted alginate microcapsules in the transplantation of insulin producing cells

Sandrine Gerber, Daniel Ortiz Trujillo, François Rémi Pierre Noverraz, Luca Szabó

The controlled release of small molecular modulators of the immune response from hydrogel microspheres (MS) used for cell immobilization is an attractive approach to reduce pericapsular fibrotic overgrowth (PFO) after transplantation. Ketoprofen is a well- ...

Renal Fanconi Syndrome and Hypophosphatemic Rickets in the Absence of Xenotropic and Polytropic Retroviral Receptor in the Nephron

Dmitri Firsov

Tight control of extracellular and intracellular inorganic phosphate (Pi) levels is critical to most biochemical and physiologic processes. Urinary Pi is freely filtered at the kidney glomerulus and is reabsorbed in the renal tubule by the action of the ap ...

Functional analysis of Bicc1 and novel interacting proteins in renal tubule cell metabolism and polycystic kidneys

Lucía Carolina Leal Esteban

Genetic disorders known as ciliopathies develop polycystic kidneys, including autosomal dominant and autosomal recessive polycystic kidney diseases (ADPKD and ARPKD). Several signaling pathways including the cAMP/PKA pathway are implicated in driving cyst ...

A role for HOX13 proteins in the regulatory switch between TADs at the HoxD locus

Denis Duboule, Anamaria Necsulea, Nicolas Lonfat

During vertebrate limb development, Hoxd genes are regulated following a bimodal strategy involving two topologically associating domains (TADs) located on either side of the gene cluster. These regulatory landscapes alternatively control different subsets ...
