A Role for Two-Pore Channel Type 2 (TPC2)-Mediated Regulation of Membrane Contact Sites During Zebrafish Notochord Biogenesis?

open access: yesContact, 2023
We have previously shown that in the developing trunk of zebrafish embryos, two-pore channel type 2 (TPC2)-mediated Ca 2+ release from endolysosomes plays a role in the formation of the skeletal slow muscle.

Zebrafish inversin mutants develop scoliosis in the absence of laterality defects

open access: yesDevelopmental Dynamics, EarlyView.
Abstract Background Human mutations in INVERSIN are associated with nephronophthisis, variable penetrance of situs inversus and congenital heart disease. Inversin has been shown to localize to cilia and many of the patient phenotypes are attributed to disrupted cilia function.

The Enigmatic Reissner’s Fiber and the Origin of Chordates

open access: yesFrontiers in Neuroanatomy, 2021
Reissner’s fiber (RF) is a secreted filament that floats in the neural canal of chordates. Since its discovery in 1860, there has been no agreement on its primary function, and its strong conservation across chordate species has remained a mystery for ...

Zebrafish ventral gastrula fate map reveals neural crest progenitor domain

open access: yesDevelopmental Dynamics, EarlyView.
Abstract Background Fate maps relate progenitor cell positions to later fates and locations of their progeny, revealing early embryonic organization. Previous zebrafish fate maps identified the origin of germ layers and derivative cell fates, but ventral gastrula progenitor domains were not fully resolved. In particular, the neural crest, a multipotent

Anti‐Inflammatory Effects of Punicic Acid and Its Molecular Mechanisms in RAW264.7 Cells and Zebrafish

open access: yesFood Safety and Health, EarlyView.
Punicic acid (PA) was enriched and purified from PSO by molecular distillation with significant anti‐inflammatory activity to RAW264.7 cells, as well as to zebrafish. Anti‐inflammatory mechanism involved regulating NF‐κB and MAPK signaling pathways. ABSTRACT Punicic acid (PA) is the main fatty acid in pomegranate seeds, which shows multiple biological ...

Segmentation of the zebrafish axial skeleton relies on notochord sheath cells and not on the segmentation clock

open access: yeseLife, 2018
Segmentation of the axial skeleton in amniotes depends on the segmentation clock, which patterns the paraxial mesoderm and the sclerotome. While the segmentation clock clearly operates in teleosts, the role of the sclerotome in establishing the axial ...

Programmed Cell Senescence in the Mouse Developing Spinal Cord and Notochord

open access: yesFrontiers in Cell and Developmental Biology, 2021
Programmed cell senescence is a cellular process that seems to contribute to embryo development, in addition to cell proliferation, migration, differentiation and programmed cell death, and has been observed in evolutionary distant organisms such as ...

Translating Riedl: The Circulation and Operationalisation of Evolutionary Ideas

open access: yesJournal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.
Rupert Riedl's Order in Living Organisms proposed a systems theory of evolution decades before the concepts it pioneered—homology, burden, the imitative epigenotype—reached the agenda of evolutionary biology. This paper reconstructs the lineages that operationalized his insights across several fields and explores the internal and external reasons for ...

Notochord Patterning of the Endoderm

open access: yesDevelopmental Biology, 2001
Endodermally derived organs of the gastrointestinal and respiratory system form at distinct anterioposterior and dorsoventral locations along the vertebrate body axis. This stereotyped program of organ formation depends on the correct patterning of the endodermal epithelium so that organ differentiation and morphogenesis occur at appropriate positions ...

The ancient, segmented, active and permanent notochord

open access: yes, 2021
The discovery of the notochord as a feature uniting all chordates arose from comparative embryological studies in the 19th century. This discovery established cephalochordates, ascidians (tunicates) and vertebrates as chordates.
