Bioinformatics and Mass Spectrometry for Neuropeptide Characterization
… and gene products in insect, echinoderms and chordates along with neuropeptide processing predictors present generalized and successful approaches for neuropeptide discovery in any organism.

How to build a chordate: Multiscale decomposition of axial morphogenesis in the amphioxus, Branchiostoma lanceolatum
… is remarkable anatomical diversity between adult chordates, they are all united by a common set of design principles. The epicentre of the body plan is the notochord, located at the axial midline, which is flanked dorsally by a neural tube, bilaterally by a metameric pattern of somites, and …

Carbohydrate and bacterial binding specificity of human intelectin-1
… lectins, or intelectins, are found throughout chordates and share highly conserved sequences but their biological roles are not well understood.

Novel Mechanisms in Zebrafish Otolith Nucleation, Tethering, and Dysfunction
… as a mediator of biomineralization events in chordates and echinoderms, I demonstrate that it is evolutionarily conserved in zebrafish. The role and function of vertebrate Otolin-1 has been expanded by the characterization of hair-cell specific otolin-1b. Finally, I provide the groundwork for …

Synthesis of a Middle Pennsylvanian soft-bodied fauna from western Illinois
… worms, arthropods, a holothurian, numerous chordates (mainly fishes), and problematic fossils. Many species had been previously known only from the Mazon Creek area of northern Illinois. In an examination of 67 localities containing fossiliferous concretions from Illinois and Missouri, …

Characterization of Nuclear Localization Signals of Karyopherin-Mediated Nuclear Import
… from fungi to nematodes and insects to chordates.

Paleozoology of cores from the Tyler Formation (Pennsylvanian) in North Dakota, U.S.A.
… 2 malacostracans, 1 insect, and 1 echinoderm. Chordates include 1 "nonmarine" shark, at least 1 paleoniscoid fish, and 1 possible crossopterygian fish. A new genus and species of eocarid malacostracan is described and represents the first report of the family Tealliocarididae from. North …

Evolutionary and Developmental Survey of Genes Involved in Chordate Pigmentation
… to depict Rab evolution, with a special focus on chordates that exhibit a highly dynamic evolutionary pattern. <br></br><br></br> I clarified the evolution of Rab32/38 subfamily, fundamental in regulation of trafficking related to melanogenesis. It has been clarified the evolutionary history of …

Ancient origins of the chordate forebrain: Conserved patterning of the anterior neuroectoderm in amphioxus
… deuterostome phyla (echinoderms and hemichordates), in which the aGRN controls the development of the apical organ. Although clear homologs of the apical organ are not present in chordates, most aGRN genes are expressed in the vertebrate forebrain. In this PhD thesis I trace the evolution …

Immunological Crosstalk between Human Transforming Growth Factor-β1 and the Malaria Vector Anopheles stephensi
… evidence of ligand gene duplication outside of chordates. In addition to five receptors, three Smads were identified in the A. gambiae genome predicted to support TGF-β/Activin- and BMP-like signaling. Midgut epithelial cells and an immunocompetent A. stephensi cell line express all three Smads, …

VDAC and SOD1: two major players in mitochondrial metabolism and in ALS
… of VDAC proteins, composed of three isoforms in chordates, VDAC3 is the least known. Conversely from isoforms 1 and 2, its ability to form pores has been questioned. In this thesis, we present the first complete electrophysiological characterization of VDAC3, showing that this protein is able to …

DEVELOPMENT OF THE LARVAL PERIPHERAL NERVOUS SYSTEM IN THE ASCIDIAN CIONA INTESTINALIS: ROLE OF THE RETINOIC ACID AND FGF/WNT SIGNALLING PATHWAYS AND OF THE POU TRANSCRIPTION FACTORS.
… of the POU family in its differentiation. Within chordates, tunicates represent the sister group of vertebrates and their larvae have a typical chordate body plan. Notably, larval nervous system is formed by few cells whose organization mirrors that of vertebrates. For these reasons the species C. …

Feeding ecology, daily activity budget and primatourism of schlegel’s banded langur (presbytis neglectus) (schlegel,1876) in Kota Tinggi Johor
Schlegel’s banded langur, Presbytis neglectus, is an endemic leaf-eating monkey distributed in Johor but faced lacked of concern on its conservation aspect. It has the potential to be a primate-based tourism product called PrimaTourism (read: primate tourism) which is able to offer a sustainable …

Phylogenomics of vertebrate serpins
… of serpins in the time interval separating urochordates from chordates, indicating massive intron gains or losses and events providing C and N-terminal sequence extensions characteristic for today's vertebrate serpins. Lancelets and sea urchin genomes, in contrast, share one orthologous serpin …
