First documented observation of differential dorsoventral coat colouration in wild boar Sus scrofa (Artyodactyla: Suidae) in Italy

Natural History Sciences
Wild boar Sus scrofa usually shows a uniform brown coat, but different colour patterns have been observed with red, brown, black, and white morphs. Nevertheless, coat colour polymorphism is often associated with hybridization with domestic pigs.

Pou5f1 contributes to dorsoventral patterning by positive regulation of vox and modulation of fgf8a expression

, 2011
Pou5f1/Oct-4 in mice is required for maintenance of embryonic pluripotent cell populations. Zebrafish pou5f1 maternal–zygotic mutant embryos (spiel ohne grenzen; MZspg) lack endoderm and have gastrulation and dorsoventral patterning defects.

Distinct GABAergic modulation of timing-dependent LTP in CA1 pyramidal neurons along the longitudinal axis of the mouse hippocampus

iScience
Summary: Synaptic plasticity in the hippocampus underlies episodic memory formation, with dorsal hippocampus being instrumental for spatial memory whereas ventral hippocampus is crucial for emotional learning.

Localized Requirements for windbeutel and pipe Reveal a Dorsoventral Prepattern within the Follicular Epithelium of the Drosophila Ovary

, 1998
Establishment of dorsoventral polarity within the Drosophila embryo requires extraembryonic positional information generated during oogenesis. The genes windbeutel, pipe, and nudel are required within the somatic follicle cells of the ovary for ...

MCN1 neurite size differs across the dorsoventral axis.

, 2015
(A) Volume rendering of MCN1 soma (filled arrow) and smaller neurites (bracket) in the most dorsal portion of the neurite arborization (volume rendering of z-stack: 46 optical slices, 1.0 μm interval). (B) Thicker neurite branches (open arrowheads) occur

Vegetally localized Vrtn functions as a novel repressor to modulatebmp2btranscription during dorsoventral patterning in zebrafish

, 2017
The vegetal pole cytoplasm represents a critical source of maternal signals for patterning the primary dorsoventral axis of the early embryo. Vegetally localized dorsal determinants are essential for the formation of the Spemann organizer, which ...

The dorsoventral regulatory gene cassette spätzle/Toll/cactus controls the potent antifungal response in Drosophila adults [PDF]

The cytokine-induced activation cascade of NF-kappaB in mammals and the activation of the morphogen dorsal in Drosophila embryos show striking structural and functional similarities (Toll/IL-1, Cactus/I-kappaB, and dorsal/NF-kappaB).

A maternal dorsoventral prepattern revealed by an asymmetric distribution of ventralizing molecules before fertilization in Xenopus laevis

Frontiers in Cell and Developmental Biology
The establishment of the embryonic dorsoventral axis in Xenopus occurs when the radial symmetry around the egg’s animal-vegetal axis is broken to give rise to the typical symmetry of Bilaterians.

The limb dorsoventral axis: Lmx1b's role in development, pathology, evolution, and regeneration

The limb anatomy displays well-defined dorsal and ventral compartments, housing extensor, and flexor muscles, which play a crucial role in facilitating limb locomotion and manipulation.
