Annotation:

Marine invertebrates are a paraphyletic group that comprises more than 90% of all marine animal species. Lipids form the structural basis of cell membranes, are utilized as an energy reserve by all marine invertebrates, and are, therefore, considered important indicators of their ecology and biochemistry. The nutritional value of commercial invertebrates directly depends on their lipid composition. The lipid classes and fatty acids of marine invertebrates have been studied in detail, but data on their lipidomes (the profiles of all lipid molecules) remain very limited. To date, lipidomes or their parts are known only for a few species of mollusks, coral polyps, ascidians, jellyfish, sea anemones, sponges, sea stars, sea urchins, sea cucumbers, crabs, copepods, shrimp, and squid. This paper reviews various features of the lipid molecular species of these animals. The results of the application of the lipidomic approach in ecology, embryology, physiology, lipid biosynthesis, and in studies on the nutritional value of marine invertebrates are also discussed. The possible applications of lipidomics in the study of marine invertebrates are considered.

Annotation:

Le point de contrôle du fuseau mitotique (Spindle Assembly Checkpoint : SAC) retarde l’anaphase jusqu’à ce que tous les chromosomes soient attachés correctement aux microtubules. Le SAC permet ainsi d’éviter des erreurs de ségrégation des chromosomes aboutissant à des cellules filles aneuploïdes (i.e. avec un nombre anormal de chromosomes). L’aneuploïdie, délétère pour les cellules, peut entrainer des problèmes de développement et est observée dans les cancers. Cependant, chez certaines espèces, le SAC n’est pas efficace au cours de la phase précoce du développement embryonnaire. J’ai mis en évidence que chez l’ascidie P. mammillata, un organisme marin du groupe des chordés, le SAC devient efficace au 8ème cycle cellulaire et son efficacité augmente dans les cycles suivants. J’ai démontré qu’en partie ventrale l’identité des cellules antérieures induisait la présence d’un SAC plus efficace mais que d’autres facteurs modulaient aussi l’efficacité du SAC. J’ai étudié les mécanismes moléculaires impliqués dans les variations de l’efficacité du SAC au cours du développement. Mes expériences ont révélé la présence des composants du SAC tout au long de l’embryogenèse. Cependant, j’ai pu montrer que les protéines du SAC ne se localisent pas au niveau des kinétochores lorsque le SAC est inefficace au début du développement mais qu’elles s’y localisent bien dans l’ovocyte en méiose et dans l’embryon plus tardif, lequel se caractérise par un SAC actif. Ma thèse a permis de montrer que P. mammillata est un organisme expérimental de grand intérêt pour l’étude du SAC au cours de l’embryogenèse
During mitosis, progression through anaphase must take place only when all chromosomes are correctly attached to spindle microtubules to avoid chromosome mis-segregation and the generation of aneuploid cells (i.e. with an abnormal chromosome number). Embryos containing aneuploid cells can exhibit developmental defects and lethality. Furthermore, cancer cells are often aneuploid. To prevent such deleterious aneuploidy, a control mechanism, the spindle assembly checkpoint (SAC), delays metaphase-anaphase transition until all chromosomes are properly attached to spindle microtubules. However, the SAC is not efficient during early development in some species. During my thesis, I analyzed the activity of the SAC during the development of the marine chordate P. mammillata. I showed that in P. mammillata embryos, the SAC becomes efficient at the 8th cell cycle and its efficiency increases progressively in the following cell cycles. Although, I demonstrated that patterning of the embryo along the anteroposterior axis influences SAC efficiency, my experiments suggest that additional parameters modulate SAC efficiency. I searched the molecular mechanisms, which control SAC efficiency during development. I collected evidence showing that SAC components are present in oocytes and all post-fertilization stages. I found that SAC proteins localize at kinetochores during meiosis and at later stages when there is an efficient SAC while they do not accumulate on unattached kinetochores in early SAC deficient embryos. My thesis work establishes P. mammillata as a valuable experimental organism to study SAC regulation during embryogenesis

Annotation:

Abstract Until the beginning of the twentieth century classical zoology focused on the discovery and description of a large number of new species. The mode of early development, and the shape of larval stages, provided crucial parameters for the assessment of evolutionary descent and relationship to other species, more so than adult morphologies and traits. With time, zoologists interested in embryonic development per se displayed an increasing tendency to focus on particular organisms that were chosen for traits that made them amenable to experimental manipulation. Each of these organisms allowed a particular approach to be taken and together they gave rise to all of the major concepts in developmental biology. For example, from several marine organisms, such as sea urchins, eggs could be obtained in incredible numbers. Species with large robust embryos, such as amphibia and some insects, were amenable to the transplantation and ablation experiments that lead to the notion of organizing centres in embryos. Early understanding of cell lineage was gained from work on animals with invariant cell lineages that could be traced throughout development (Ascaris spp.). Some organisms were chosen for reasons that at first glance might seem insignificant. For instance, the presence of cortical pigment granules in egg cytoplasm of ascidians gave rise to the concept of cytoplasmic inheritance. Despite these advances, the incredible diversity of phenomena observed in the different systems made embryology an increasingly bewildering topic. Generalizations, or even useful comparisons, were often difficult, even within phyla. In particular, the molecules underlying these phenomena remained elusive, despite considerable efforts.
