L'équipe Veitia vient de publier un nouvel article dans Cancer Research : The Oncogenic FOXL2 C134W Mutation Is a Key Driver of Granulosa Cell Tumors   Abstract Adult-type granulosa cell tumors (AGCT) are the most common type of malignant ovarian sex cord–stromal tumors. Most AGCTs carry the somatic variant c.402C>G (p.C134W) affecting the transcription factor FOXL2. Germline…

La plateforme Protoseine vient de publier un nouvel article dans Journal of Chromatography B : Capillary liquid chromatography coupled with mass spectrometry for analysis of nanogram protein quantities on a wide-pore superficially porous particle column in top-down proteomics   Abstract In top-down proteomics experiments, intact protein ions are subjected to gas-phase fragmentation for MS analysis without…

L'équipe Grange/Geigl a récemment publié un châpitre d'ouvrage dans Microbial Environmental Genomics (Part of the Methods in Molecular Biology book series (MIMB,volume 2605) Analysis of Ancient Microbial DNA Abstract The development of next-generation sequencing has led to a breakthrough in the analysis of ancient genomes, and the subsequent genomic analyses of ancient human skeletal remains have revolutionized…

L'équipe Ladoux/Mège publie un nouvel article dans Biomaterials   Bioengineering a miniaturized in vitro 3D myotube contraction monitoring chip to model muscular dystrophies   Abstract Quantification of skeletal muscle functional contraction is essential to assess the outcomes of therapeutic procedures for neuromuscular disorders. Muscle three-dimensional “Organ-on-chip” models usually require a substantial amount of biological material, which rarely…

L'équipe Vervoort vient de publier un nouvel article dans JEZ-B: Molecular and Developmental Evolution : On the hormonal control of posterior regeneration in the annelid Platynereis dumerilii   Abstract Regeneration is the process by which many animals are able to restore lost or injured body parts. After amputation of the posterior part of its body, the annelid Platynereis dumerilii is…

L'équipe Ladoux/Mège vient de publier un article dans Nature Physics :   Mechanical stress driven by rigidity sensing governs epithelial stability Abstract: Epithelia act as barriers against environmental stresses. They are continuously exposed to various mechanical stress and abrasion, which impact epithelial integrity. The impact of the environment on epithelial integrity remains elusive. By culturing epithelial cells…

L'équipe Minc vient de publier une nouvelle revue dans Journal of Cell Science : Mechanobiology of the cell wall – insights from tip-growing plant and fungal cells ABSTRACT The cell wall (CW) is a thin and rigid layer encasing the membrane of all plant and fungal cells. It ensures mechanical integrity by bearing mechanical stresses derived…

L'équipe Veitia vient de publier un nouvel article dans Clinical Genetics :   Recurrent missense variants in clonal hematopoiesis-related genes present in the general population   Abstract Clonal hematopoiesis (CH) consists in an abnormal expansion of a hematopoietic stem cell bearing an advantageous somatic variant. A survey of known recurrent somatic missense variants in DNMT3A, SF3B1, SRSF2 and TP53, some of the…

Un nouvel article publié dans Cancers : Novel Insights into Redox-Based Mechanisms for Auranofin-Induced Rapid Cancer Cell Death Abstract Auranofin (Ridaura®, AUF) is a gold complex originally approved as an antirheumatic agent that has emerged as a potential candidate for multiple repurposed therapies. The best-studied anticancer mechanism of AUF is the inhibition of thioredoxin reductase (TrxR). However,…

L'équipe Wassmann vient de publier un nouvel article dans Developmental Cell: Cyclin B3 implements timely vertebrate oocyte arrest for fertilization Summary To ensure successful offspring ploidy, vertebrate oocytes must halt the cell cycle in meiosis II until sperm entry. Emi2 is essential to keep oocytes arrested until fertilization. However, how this arrest is implemented exclusively in…
