Introduction du numéro spécial d’Arts et Sciences sur la Station Marine de Villefranche

Elisabeth Christians

La station marine de Villefranche-sur-Mer a reçu de nombreux noms au cours de son histoire dont les deux derniers sont OOV pour Observatoire Océanologique de Villefranche (1989) et IMEV pour Institut de la Mer de Villefranche (depuis 2019). Ce numéro spécial montre …

Acquisition of the spindle assembly checkpoint and its modulation by cell fate and cell size in a chordate embryo

Marianne Roca, Lydia Besnardeau, Elisabeth Christians, Alex McDougall et autres

The spindle assembly checkpoint (SAC) is a surveillance system that preserves genome integrity by delaying anaphase onset until all chromosomes are correctly attached to spindle microtubules. Recruitment of SAC proteins to unattached kinetochores generates an inhibitory signal that prolongs mitotic duration. Chordate …

The Spindle Assembly Checkpoint Functions during Early Development in Non-Chordate Embryos

Janet Chênevert, Marianne Roca, Lydia Besnardeau, Antonella Ruggiero et autres

In eukaryotic cells, a spindle assembly checkpoint (SAC) ensures accurate chromosome segregation, by monitoring proper attachment of chromosomes to spindle microtubules and delaying mitotic progression if connections are erroneous or absent. The SAC is thought to be relaxed during early embryonic development. …

Totipotency continuity from zygote to early blastomeres: a model under revision

Michele Boiani, Ellen Casser, Georg Fuellen, Elisabeth Christians

The mammalian zygote is a totipotent cell that generates all the cells of a new organism through embryonic development. However, if one asks about the totipotency of blastomeres after one or two zygotic divisions, opinions differ. As it is impossible to determine …

The spindle assembly checkpoint functions during early development in non-chordate embryos

Janet Chênevert, Marianne Roca, Lydia Besnardeau, Antonella Ruggiero et autres

In eukaryotic cells, a spindle assembly checkpoint (SAC) ensures accurate chromosome segregation. This control mechanism monitors proper attachment of chromosomes to spindle microtubules and delays mitotic progression if connections are erroneous or absent. The SAC operates in all eukaryotic cells tested so …

The Human 343delT HSPB5 Chaperone Associated with Early-onset Skeletal Myopathy Causes Defects in Protein Solubility

Katie A. Mitzelfelt, Pattraranee Limphong, Melinda J. Choi, Frances D. L. Kondrat et autres

Mutations of HSPB5 (also known as CRYAB or αB-crystallin), a bona fide heat shock protein and molecular chaperone encoded by the HSPB5 (crystallin, alpha B) gene, are linked to multisystem disorders featuring variable combinations of cataracts, cardiomyopathy, and skeletal myopathy. This study …

Characterization of the Cardiac Overexpression of HSPB2 Reveals Mitochondrial and Myogenic Roles Supported by a Cardiac HspB2 Interactome

Julianne H. Grose, Kelsey Murphey Langston, Xiaohui Wang, Shayne Squires et autres

Small Heat Shock Proteins (sHSPs) are molecular chaperones that transiently interact with other proteins, thereby assisting with quality control of proper protein folding and/or degradation. They are also recruited to protect cells from a variety of stresses in response to extreme heat, …
