How are cells instructed to form somite boundaries by the zebrafish segmentation clock?

Olivier François Venzin

In vertebrate embryos, the elongating body axis is patterned via the sequential and rhyth-mic production of segments from a posterior unsegmented tissue called the presomitic mesoderm (PSM). This process is controlled by a population of cellular oscillator ...

Caspase-9-mediated cleavage of vimentin attenuates the aggressiveness of leukemic NB4 cells

Cyrus Kazemiraad

Vimentin is a main type 3 intermediate filament protein. It seems that abnormal expression of vimentin is contributed to the appearance of the aggressive feature of cancer cells. So that it has been reported that malignancy and epithelial-mesenchymal trans ...

Mammalian adipogenesis regulator (Areg) cells use retinoic acid signalling to be non- and anti-adipogenic in age-dependent manner

Bart Deplancke, Daniel Alpern, Julie Marie Russeil, Maria Litovchenko, Pernille Yde Rainer, Magda Zachara, Radiana Ferrero, Horia Hashimi

Adipose stem and precursor cells (ASPCs) give rise to adipocytes and determine the composition and plasticity of adipose tissue. Recently, several studies have demonstrated that ASPCs partition into at least three distinct cell subpopulations, including th ...

HOX13-dependent chromatin accessibility underlies the transition towards the digit development program

Alexandre Gauthier Aurèle Mayran

Hox genes encode transcription factors (TFs) that establish morphological diversity in the developing embryo. The similar DNA-binding motifs of the various HOX TFs contrast with the wide-range of HOX-dependent genetic programs. The influence of the chromat ...

Integration of Shh and Fgf signaling in controlling Hox gene expression in cultured limb cells

Denis Duboule, Guillaume Andrey, Patrick Schorderet

During embryonic development, fields of progenitor cells form complex structures through dynamic interactions with external signaling molecules. How complex signaling inputs are integrated to yield appropriate gene expression responses is poorly understood ...

RING1 proteins contribute to early proximal-distal specification of the forelimb bud by restricting Meis2 expression

Polycomb group (PcG) proteins play a pivotal role in silencing developmental genes and help to maintain various stem and precursor cells and regulate their differentiation. PcG factors also regulate dynamic and complex regional specification, particularly ...

Mutations in ALDH1A3 Represent a Frequent Cause of Microphthalmia/Anophthalmia in Consanguineous Families

Tatiana Favez

Anophthalmia or microphthalmia (A/M), characterized by absent or small eye, can be unilateral or bilateral and represent developmental anomalies due to the mutations in several genes. Recently, mutations in aldehyde dehydrogenase family 1, member A3 (ALDH1 ...

3D Reconstitution of the Patterned Neural Tube from Embryonic Stem Cells

Matthias Lütolf, Adrian Ranga

Inducing organogenesis in 3D culture is an important aspect of stem cell research. Anterior neural structures have been produced from large embryonic stem cell (ESC) aggregates, but the steps involved in patterning such complex structures have been ill def ...

ALDH1A3 loss of function causes bilateral anophthalmia/microphthalmia and hypoplasia of the optic nerve and optic chiasm

The major active retinoid, all-trans retinoic acid, has long been recognized as critical for the development of several organs, including the eye. Mutations in STRA6, the gene encoding the cellular receptor for vitamin A, in patients with MatthewWood syndr ...

Bigh3 Is Upregulated in Regenerating Zebrafish Fin

Zebrafish is a good model for studying regeneration because of the rapidity with which it occurs. Better understanding of this process may lead in the future to improvement of the regenerating capacity of humans. Signaling factors are the second largest ca ...

The Mucosal Adjuvant Cholera Toxin B Instructs Non-Mucosal Dendritic Cells to Promote IgA Production Via Retinoic Acid and TGF-β

Nicola Harris

It is currently unknown how mucosal adjuvants cause induction of secretory immunoglobulin A (IgA), and how T cell-dependent (TD) or -independent (TI) pathways might be involved. Mucosal dendritic cells (DCs) are the primary antigen presenting cells driving ...

Partial promoter substitutions generating transcriptional sentinels of diverse signaling pathways in embryonic stem cells and mice

Anne Grapin-Botton

Extracellular signals in development, physiology, homeostasis and disease often act by regulating transcription. Herein we describe a general method and specific resources for determining where and when such signaling occurs in live animals and for systema ...

Retinoic acid signaling organizes endodermal organ specification along the entire antero-posterior axis

Anne Grapin-Botton

BACKGROUND: Endoderm organ primordia become specified between gastrulation and gut tube folding in Amniotes. Although the requirement for RA signaling for the development of a few individual endoderm organs has been established a systematic assessment of i ...

Corneal epithelial cell fate is maintained during repair by Notch1 signaling via the regulation of vitamin A metabolism

Freddy Radtke, Yann Barrandon

Integrity and preservation of a transparent cornea are essential for good vision. The corneal epithelium is stratified and nonkeratinized and is maintained and repaired by corneal stem cells. Here we demonstrate that Notch1 signaling is essential for cell ...
