A novel role for Ets4 in axis specification and cell migration in the spider Parasteatoda tepidariorum

open access: yeseLife, 2017
Organizers play important roles during the embryonic development of many animals. The most famous example is the Spemann organizer that sets up embryonic axes in amphibian embryos.

Evolution of Insect Dorsoventral Patterning Mechanisms [PDF]

open access: yesCold Spring Harbor Symposia on Quantitative Biology, 2009
The dorsoventral (DV) patterning of the early Drosophila embryo depends on Dorsal, a maternal sequence-specific transcription factor related to mammalian NF-kappaB. Dorsal controls DV patterning through the differential regulation of approximately 50 target genes in a concentration-dependent manner.

Combined Effects of Water Depth and Velocity on the Accelerometric Parameters Measured in Horses Exercised on a Water Treadmill

open access: yesAnimals, 2020
Horse trainers often claim that exercise on a water treadmill (WT) leads to a greater muscle power and development compared to terrestrial locomotion, because of the greater viscosity of water compared to air.

Dorsoventral patterning in hemichordates: insights into early chordate evolution. [PDF]

open access: yesPLoS Biology, 2006
We have compared the dorsoventral development of hemichordates and chordates to deduce the organization of their common ancestor, and hence to identify the evolutionary modifications of the chordate body axis after the lineages split. In the hemichordate

The Selector Gene apterous and Notch Are Required to Locally Increase Mechanical Cell Bond Tension at the Drosophila Dorsoventral Compartment Boundary. [PDF]

open access: yesPLoS ONE, 2016
The separation of cells with distinct fates and functions is important for tissue and organ formation during animal development. Regions of different fates within tissues are often separated from another along straight boundaries.

Visual Field Coordinate Systems in Visual Neurophysiology [PDF]

open access: yesAnais da Academia Brasileira de Ciências, 2023
In this work, algorithms have been developed to: 1. Compare visual field coordinate data, presented in different representation systems; 2. Determine the distance in degrees between any two points in the visual field; 3.

Laminar and dorsoventral molecular organization of the medial entorhinal cortex revealed by large-scale anatomical analysis of gene expression. [PDF]

open access: yesPLoS Computational Biology, 2015
Neural circuits in the medial entorhinal cortex (MEC) encode an animal's position and orientation in space. Within the MEC spatial representations, including grid and directional firing fields, have a laminar and dorsoventral organization that ...

Eph regulates dorsoventral asymmetry of the notochord plate and convergent extension-mediated notochord formation. [PDF]

open access: yesPLoS ONE, 2010
The notochord is a signaling center required for the patterning of the vertebrate embryonic midline, however, the molecular and cellular mechanisms involved in the formation of this essential embryonic tissue remain unclear.

Ontogeny of ependymoglial cells lining the third ventricle in mice

open access: yesFrontiers in Endocrinology, 2023
IntroductionDuring hypothalamic development, the germinative neuroepithelium gives birth to diverse neural cells that regulate numerous physiological functions in adulthood.MethodsHere, we studied the ontogeny of ependymal cells in the mouse mediobasal ...

Conservation and diversification of an ancestral chordate gene regulatory network for dorsoventral patterning.

open access: yesPLoS ONE, 2011
Formation of a dorsoventral axis is a key event in the early development of most animal embryos. It is well established that bone morphogenetic proteins (Bmps) and Wnts are key mediators of dorsoventral patterning in vertebrates.
