Comparative Expression of Zebrafish Lats1 and Lats2 and Their Implication in Gastrulation Movements

Large tumor suppressor (Lats) is a Ser/Thr kinase, and it presents an important function in tumor suppression. lats was originally identified in Drosophila and recently in mammals. In mammals, it contains two homologues, lats1 and lats2. In the present study, lats1 and lats2 were characterized from zebrafish (Danio rerio), which is the first report of lats in a nonmammalian vertebrate. The primary structure, genomic organization, and phylogenesis of lats from different species were studied, and the results suggest that lats1 is the direct descendant of invertebrate lats, whereas lats2 is formed by genome duplication. In zebrafish, both lats genes are maternally expressed, while they show distinctly different expression profiles during gastrulation. lats1 is almost ubiquitously expressed through development, and lats2 is more prominently expressed in the non-neural ectoderm region of zebrafish gastrula. Most intriguingly, as revealed by cell tracing and gene expression analysis, morpholino-mediated knockdown of either lats1 or lats2 led to obvious defects of cell migration in gastrulation, indicating the functional significance of lats in gastrulation movements.

Comparative expression analysis of transcription factor genes in the endostyle of invertebrate chordates

The endostyle of invertebrate chordates is a pharyngeal organ that is thought to be homologous with the follicular thyroid of vertebrates. Although thyroid-like features such as iodine-concentrating and peroxidase activities are located in the dorsolateral part of both ascidian and amphioxus endostyles, the structural organization and numbers of functional units are different. To estimate phylogenetic relationships of each functional zone with special reference to the evolution of the thyroid, we have investigated, in ascidian and amphioxus, the expression patterns of thyroid-related transcription factors such as TTF-2/MoxE4 and Pax2/5/8, as well as the forkhead transcription factors FoxQ1 and FoxA. Comparative gene expression analyses depicted an overall similarity between ascidians and amphioxus endostyles, while differences in expression patterns of these genes might be specifically related to the addition or elimination of a pair of glandular zones. Expressions of Ci-FoxE and BbFoxE4 suggest that the ancestral FoxE class might have been recruited for the formation of thyroid-like region in a possible common ancestor of chordates. Furthermore, coexpression of FoxE4, Pax2/5/8, and TPO in the dorsolateral part of both ascidian and amphioxus endostyles suggests that genetic basis of the thyroid function was already in place before the vertebrate lineage.

A unified anatomy ontology of the vertebrate skeletal system.

The skeleton is of fundamental importance in research in comparative vertebrate morphology, paleontology, biomechanics, developmental biology, and systematics. Motivated by research questions that require computational access to and comparative reasoning across the diverse skeletal phenotypes of vertebrates, we developed a module of anatomical concepts for the skeletal system, the Vertebrate Skeletal Anatomy Ontology (VSAO), to accommodate and unify the existing skeletal terminologies for the species-specific (mouse, the frog Xenopus, zebrafish) and multispecies (teleost, amphibian) vertebrate anatomy ontologies. Previous differences between these terminologies prevented even simple queries across databases pertaining to vertebrate morphology. This module of upper-level and specific skeletal terms currently includes 223 defined terms and 179 synonyms that integrate skeletal cells, tissues, biological processes, organs (skeletal elements such as bones and cartilages), and subdivisions of the skeletal system. The VSAO is designed to integrate with other ontologies, including the Common Anatomy Reference Ontology (CARO), Gene Ontology (GO), Uberon, and Cell Ontology (CL), and it is freely available to the community to be updated with additional terms required for research. Its structure accommodates anatomical variation among vertebrate species in development, structure, and composition. Annotation of diverse vertebrate phenotypes with this ontology will enable novel inquiries across the full spectrum of phenotypic diversity.

Muscle Logic: New Knowledge Resource for Anatomy Enables Comprehensive Searches of the Literature on the Feeding Muscles of Mammals.

BACKGROUND: In recent years large bibliographic databases have made much of the published literature of biology available for searches. However, the capabilities of the search engines integrated into these databases for text-based bibliographic searches are limited. To enable searches that deliver the results expected by comparative anatomists, an underlying logical structure known as an ontology is required. DEVELOPMENT AND TESTING OF THE ONTOLOGY: Here we present the Mammalian Feeding Muscle Ontology (MFMO), a multi-species ontology focused on anatomical structures that participate in feeding and other oral/pharyngeal behaviors. A unique feature of the MFMO is that a simple, computable, definition of each muscle, which includes its attachments and innervation, is true across mammals. This construction mirrors the logical foundation of comparative anatomy and permits searches using language familiar to biologists. Further, it provides a template for muscles that will be useful in extending any anatomy ontology. The MFMO is developed to support the Feeding Experiments End-User Database Project (FEED, https://feedexp.org/), a publicly-available, online repository for physiological data collected from in vivo studies of feeding (e.g., mastication, biting, swallowing) in mammals. Currently the MFMO is integrated into FEED and also into two literature-specific implementations of Textpresso, a text-mining system that facilitates powerful searches of a corpus of scientific publications. We evaluate the MFMO by asking questions that test the ability of the ontology to return appropriate answers (competency questions). We compare the results of queries of the MFMO to results from similar searches in PubMed and Google Scholar. RESULTS AND SIGNIFICANCE: Our tests demonstrate that the MFMO is competent to answer queries formed in the common language of comparative anatomy, but PubMed and Google Scholar are not. Overall, our results show that by incorporating anatomical ontologies into searches, an expanded and anatomically comprehensive set of results can be obtained. The broader scientific and publishing communities should consider taking up the challenge of semantically enabled search capabilities.

A FUNCTIONAL, COMPARATIVE AND CLINICAL ANALYSIS OF SPERM-BORNE OOCYTE ACTIVATING FACTOR, PAWP

Successful fertilization depends upon the activation of metaphase II arrested oocytes by sperm-borne oocyte activating factor (SOAF). Failure of oocyte activation is considered as the cause of treatment failure in a proportion of infertile couples. SOAF induces the release of intracellular calcium in oocyte which leads to meiotic resumption and pronuclear formation. Calcium release is either in the form of single calcium transient in echinoderm and amphibian oocytes or several calcium oscillations in ascidian and mammalian oocytes. Although the SOAF attributes are established, it is not clear which sperm protein(s) play such role. Sperm postacrosomal WW binding protein (PAWP) satisfies a developmental criteria set for a candidate SOAF. This study shows that recombinant human PAWP protein or its transcript acts upstream of calcium release and fully activates the amphibian and mammalian oocytes. Interference trials provided evidence for the first time that PAWP mediates sperm-induced intracellular calcium release through a PPXY/WWI domain module in Xenopus, mouse and human oocytes. Clinical applications of PAWP were further investigated by prospective study on the sperm samples from patients undergoing intracytoplasmic sperm injection (ICSI). PAWP expression level, analyzed by flow cytometry, was correlated to ICSI success rate and embryonic development. This study also explored the developmental expression of the other SOAF candidate, PLCζ in male reproductive system and its function during fertilization. Our findings showed for the first time that PLCζ most likely binds to the sperm head surface during epididymal passage and is expressed in epididymis. We demonstrated that PLCζ is also compartmentalized early in spermiogenesis and thus could play an important role during spermiogenesis. Detailed analysis of in vitro fertilization revealed that PLCζ disappears from sperm head during acrosome reaction and is not detectable during sperm incorporation into the oocyte cytoplasm. In conclusion, this dissertation provides evidence for the essential non-redundant role of sperm PAWP in amphibian and mammalian fertilization; recommends PAWP as a biomarker for prediction of ICSI outcomes in infertile couples; and proposes that sperm PLCζ may have functions other than inducing oocyte activation during fertilization.

Étude comparative de l'anatomie des plaies de greffe de cornée par tomographie de cohérence optique (OCT)

Cette thèse porte sur l’étude de l’anatomie de la cornée après 3 techniques de greffe soient, la greffe totale traditionnelle (GTT) et des techniques de greffe lamellaire postérieur (GLP) telles que la greffe lamellaire endothéliale profonde (DLEK) et la greffe endothélium/membrane de Descemet (EDMG) pour le traitement des maladies de l’endothélium, telles que la dystrophie de Fuchs et de la kératopathie de l’aphaque et du pseudophaque. Dans ce contexte, cette thèse contribue également à démontrer l’utilité de la tomographie de cohérence optique (OCT) pour l’étude de l’anatomie des plaies chirurgicales la cornée post transplantation. Au cours de ce travail nous avons étudié l'anatomie de la DLEK, avant et 1, 6, 12 et 24 mois après la chirurgie. Nous avons utilisé le Stratus OCT (Version 3, Carl Zeiss, Meditec Inc.) pour documenter l’anatomie de la plaie. L'acquisition et la manipulation des images du Stratus OCT, instrument qui à été conçu originalement pour l’étude de la rétine et du nerf optique, ont été adaptées pour l'analyse du segment antérieur de l’oeil. Des images cornéennes centrales verticales et horizontales, ainsi que 4 mesures radiaires perpendiculaires à la plaie à 12, 3, 6 et 9 heures ont été obtenues. Les paramètres suivants ont été étudiés: (1) Les espaces (gap) entre les rebords du disque donneur et ceux du receveur, (2) les dénivelés de surface postérieure (step) entre le les rebords du disque donneur et ceux du receveur, (3) la compression tissulaire, (4) le décollement du greffon, 6) les élévations de la surface antérieure de la cornée et 7) la pachymétrie centrale de la cornée. Les mesures d’épaisseur totale de la cornée ont été comparées et corrélées avec celles obtenues avec un pachymètre à ultra-sons. Des mesures d’acuité visuelle, de réfraction manifeste et de topographie ont aussi été acquises afin d’évaluer les résultats fonctionnels. Enfin, nous avons comparé les données de DLEK à celles obtenues de l’EDMG et de la GTT, afin de caractériser les plaies et de cerner les avantages et inconvénients relatifs à chaque technique chirurgicale. Nos résultats anatomiques ont montré des différences importantes entre les trois techniques chirurgicales. Certains des paramètres étudiés, comme le sep et le gap, ont été plus prononcés dans la GTT que dans la DLEK et complètement absents dans l’EDMG. D’autres, comme la compression tissulaire et le décollement du greffon n’ont été observés que dans la DLEK. Ceci laisse entrevoir que la distorsion de la plaie varie proportionnellement à la profondeur de la découpe stromale du receveur, à partir de la face postérieure de la cornée. Moins la découpe s’avance vers la face antérieure (comme dans l’EDMG), moins elle affecte l’intégrité anatomique de la cornée, le pire cas étant la découpe totale comme dans la GTT. Cependant, tous les paramètres d’apposition postérieure sous-optimale et d’élévation de la surface antérieure (ce dernier observé uniquement dans la GTT) finissent par diminuer avec le temps, évoluant à des degrés variables vers un profil topographique plus semblable à celui d’une cornée normale. Ce processus paraît plus long et plus incomplet dans les cas de GTT à cause du type de plaie, de la présence de sutures et de la durée de la cicatrisation. Les valeurs moyennes d’épaisseur centrale se sont normalisées après la chirurgie. De plus, ces valeurs moyennes obtenues par OCT étaient fortement corrélées à celles obtenues par la pachymétrie à ultra-sons et nous n’avons remarqué aucune différence significative entre les valeurs moyennes des deux techniques de mesure. L’OCT s’est avéré un outil utile pour l’étude de l’anatomie microscopique des plaies chirurgicales. Les résultats d’acuité visuelle, de réfraction et de topographie des techniques de GLP ont montré qu’il existe une récupération visuelle rapide et sans changements significatifs de l’astigmatisme, contrairement à la GTT avec et sans suture. La GLP a permis une meilleure conservation de la morphologie de la cornée, et par conséquence des meilleurs résultats fonctionnels que la greffe de pleine épaisseur. Ceci nous permet d’avancer que la GLP pourrait être la technique chirurgicale à adopter comme traitement pour les maladies de l’endothélium cornéen.
