Zebrafish as a model for Catel–Manzke syndrome—identification and characterization of the zebrafish TGDS ortholog

The FEBS Journal, EarlyView.
Zebrafish Tgds, when expressed as a recombinant protein, catalyzes the dehydration of UDP‐D‐glucose, the initial step in the formation of 6‐deoxyhexoses. Corresponding Tgds mutations found in Catel–Manzke syndrome patients lead to reduced enzymatic activity and stability.

Epiboly in zebrafish requires reactive oxygen species produced by NADPH oxidases for the regulation of vesicular trafficking

bioRxiv
Epiboly is the first morphogenetic cell movement that occurs at the onset of gastrulation in zebrafish. During epiboly, the blastoderm thins out and spreads cells over the massive yolk cell.

Organization and function of microfilaments during late epiboly in zebrafish embryos [PDF]

Developmental Dynamics, 2004
AbstractWe report that, during epiboly in zebrafish, three F‐actin–based structures appear only after the blastoderm migrates past the embryonic equator. They are composed of two ring‐like F‐actin structures that form at the deep cell and enveloping layer margins of the blastoderm and a punctate actin band that develops in the external yolk syncytial ...

Multiple cis‐regulatory elements collaborate to control mdka expression in telencephalic neural stem cells of adult zebrafish during constitutive and regenerative neurogenesis

The FEBS Journal, EarlyView.
midkine‐a (mdka), a pan‐injury response gene in vertebrates, is precisely regulated in the zebrafish telencephalon by a modular cis‐regulatory architecture. This control ensures proper expression during development, adult brain homeostasis, and regeneration.

Inhibition of methyltransferase activity of enhancer of zeste 2 leads to enhanced lipid accumulation and altered chromatin status in zebrafish

Epigenetics & Chromatin, 2020
Background Recent studies indicate that exposure to environmental chemicals may increase susceptibility to developing metabolic diseases. This susceptibility may in part be caused by changes to the epigenetic landscape which consequently affect gene ...

Reproduction and embryonic development of monkeyface prickleback Cebidichthys violaceus in captivity

Journal of Fish Biology, EarlyView.
Abstract Understanding the sequence of embryonic and larval development and the factors necessary to induce reproduction in captivity are critical for developing new species for commercial or conservation aquaculture. In this study, we describe the adult reproductive behaviours and development of eggs, embryos and early larvae of captive monkeyface ...

Soft Modular Robotic Cubes: Toward Replicating Morphogenetic Movements of the Embryo. [PDF]

PLoS ONE, 2017
In this paper we present a new type of simple, pneumatically actuated, soft modular robotic system that can reproduce fundamental cell behaviors observed during morphogenesis; the initial shaping stage of the living embryo.

Changes in microtubule stability in zebrafish (Danio rerio) embryos after glyphosate exposure

Heliyon, 2021
Glyphosate, the most commonly used pesticide worldwide, blocks aromatic amino acid biosynthetic pathways and inhibits growth in plants. Although the specific mode of action of glyphosate in animals remains unclear, adverse effects during embryonic ...

Macrophages Mediate Mesoscale Brain Mechanical Homeostasis

Advanced Materials, Volume 38, Issue 6, 27 January 2026.
We investigated the role of infiltrating immune cells in sculpting the developing brain. Using Brillouin microscopy and active microrheology, we found microglia actively maintain tissue viscoelasticity. Moreover, colony stimulating factor one receptor (CSF1R)‐driven stromal remodeling alters brain mechanics in vivo. These findings link immune activity,

The Early Development of the Blue‐Eye Cichlid, Cryptoheros spilurus (Cichliformes: Cichlidae)

Evolution &Development, Volume 27, Issue 4, December 2025.
We document the early development of Cryptoheros spilurus, highlighting rapid cranial differentiation, sensory organ formation, and fin development. Ontogenetic allometry and ultrastructural traits reveal functional adaptations for early foraging and locomotion, offering insights into ecological success and the developmental basis of cichlid ...
