1,2,3-Dithiazoles-new reversible melanin synthesis inhibitors: A chemical genomics study
(2015)A chemical genomic screen of an in-house library of small molecule heterocycles was carried out using Xenopus laevis embryos. This led to the identification of N-(4-chloro-5H-1,2,3-dithiazol-5-ylidene)-4-methoxyaniline ...

Activation of endogenous FAK via expression of its amino terminal domain in xenopus embryos
(2012)Background: The Focal Adhesion Kinase is a well studied tyrosine kinase involved in a wide number of cellular processes including cell adhesion and migration. It has also been shown to play important roles during embryonic ...

Addressing the Functional Determinants of FAK during Ciliogenesis in Multiciliated Cells
(2017)We previously identified focal adhesion kinase (FAK) as an important regulator of ciliogenesis in multiciliated cells. FAK and other focal adhesion (FA) proteins associate with the basal bodies and their striated rootlets ...

Calpain2 protease: A new member of the Wnt/Ca2+ pathway modulating convergent extension movements in Xenopus
(2013)Calpains are a family of calcium-dependent intracellular cysteine proteases that regulate several physiological processes by limited cleavage of different substrates. The role of Calpain2 in embryogenesis is not clear with ...

Cell-Autonomous Ca(2+) Flashes Elicit Pulsed Contractions of an Apical Actin Network to Drive Apical Constriction during Neural Tube Closure
(2015)Neurulation is a critical period in all vertebrates and results in the formation of the neural tube, which gives rise to the CNS. Apical constriction is one of the fundamental morphogenetic movements that drives neural ...

Comparing intracellular stability and targeting of sulfobetaine quantum dots with other surface chemistries in live cells
(2012)The in vivo labeling of intracellular components with quantum dots (QDs) is very limited because of QD aggregation in the cell cytoplasm and/or QD confinement into lysosomal compartments. In order to improve intracellular ...

A dominant-negative provides new insights into FAK regulation and function in early embryonic morphogenesis
(2013)FAK is a non-receptor tyrosine kinase involved in a wide variety of biological processes and crucial for embryonic development. In this manuscript, we report the generation of a new FAK dominant negative (FF), composed of ...

The identification and characterization of KRAB-domain-containing zinc finger proteins
(1992)The zinc finger motif is a highly conserved tandemly repeated sequence of 28-30 amino acids that was first identified in transcription factor TFIIIA from Xenopus laevis. Subsequently, similar motifs were found and characterized ...

Identification of ciliary adhesion complexes and characterization of the role of FAK in ciliogenesis
(Πανεπιστήμιο Κύπρου, Σχολή Θετικών και Εφαρμοσμένων Επιστημών / University of Cyprus, Faculty of Pure and Applied Sciences, 2015-11)Οι κροσσοί είναι σημαντικές δομές των κυττάρων και αποτελούν οργανίδια τα οποία προεκβάλλουν από την κορυφαία επιφάνεια των κυττάρων συμμετέχοντας σε καθοριστικές λειτουργίες των οργανισμών. Η δυσλειτουργία των κροσσών ...

Imaging morphogenesis, in Xenopus with Quantum Dot nanocrystals
(2009)Mesoderm migration is a well studied morphogenetic movement that takes place during Xenopus gastrulation. The study of mesoderm migration and other morphogenetic movements has been primarily based on in vitro assays due ...

Article
In vivo, site-specific, covalent conjugation of quantum dots to proteins via split-intein splicing
(2012)The ability to target proteins with nanostructures and/or nanodevices in vivo is important for understanding and controlling their biological function. Quantum dots (QDs) serve as an ideal model nanostructure due to their ...

Spatially and temporally regulated α6 integrin cleavage during Xenopus laevis development
(2008)The α6 integrin is essential for early nervous system development in Xenopus laevis. We have previously reported a uPA cleaved form of integrin α6 (α6p), in invasive human prostate cancer tissue, whose presence correlates ...
