Calcium mediates dorsoventral patterning of mesoderm in Xenopus [PDF]
Calcium signals participate in the differentiation of electrically excitable and nonexcitable cells; one example of this differentiation is the acquisition of mature neuronal phenotypes. For example, transient elevations of the intracellular calcium concentration have been recorded in the ectoderm of early embryos, and this elevation has been proposed ...

Dorsoventral Patterning: A Serpin Pinned down at Last [PDF]
Dorsoventral patterning in Drosophila has long been known to involve a cascade of proteases, held in the inactive zymogen state prior to signaling. At long last, the prediction that a protease inhibitor is involved in this pathway has been shown to be true, with the identification of a serpin that plays a key part in Drosophila embryonic patterning.

Dorsoventral patterning in plants [PDF]
Although mutations affecting dorsoventral patterning in plants have been known for centuries (Linnaeus 1749), the underlying mechanisms controlling this process have remained mysterious. Recent papers by Sawa et al. (1999b) and others have begun to shed light on this subject through the isolation and characterization of genes responsible for ...

Understanding Dorsoventral Topography [PDF]
Retinal axons project to their central targets along two orthogonal topographic axes, anterior-posterior (A-P) and dorsal-ventral (D-V). While ephrin-A/EphA signaling determines A-P topography, little has been known about the molecular mechanisms guiding axons along the D-V axis. Two papers by Mann et al. and Hindges et al.

Dorsoventral splitting of the infundibulum in a child with pituitary hypoplasia
Pituitary development arises from ectodermal tissue creating Rathke's pouch and ultimately the adenohypophysis anteriorly whereas neuroectodermal tissue arising from the diencephalon creates the neurohypophysis posteriorly. Alterations in pituitary development can lead to hormonal dysregulation and dysfunction. Following clinical suspicion of pituitary

Evolution of Insect Dorsoventral Patterning Mechanisms [PDF]
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.

The mechanisms of dorsoventral patterning in the vertebrate neural tube
We describe the essential features of and the molecules involved in dorsoventral (DV) patterning in the neural tube. The neural tube is, from its very outset, patterned in this axis as there is a roof plate, floor plate, and differing numbers and types of neuroblasts.

Neurogenin3 restricts serotonergic neuron differentiation to the hindbrain [PDF]
The development of the nervous system is critically dependent on the production of functionally diverse neuronal cell types at their correct locations.

Dorso-ventral (DV) countershading is a highly-conserved pigmentary adaptation in vertebrates. In mammals, spatially regulated expression of agouti-signaling protein (ASIP) generates the difference in shading by driving a switch between the production of ...
