Draxin, a recently identified axon guidance protein, is essential for the formation of forebrain commissures, and can mediate repulsion of netrin-stimulated spinal commissural axons. Here, we report that draxin binds multiple netrin receptors: DCC (deleted in colorectal cancer), Neogenin, UNC5s (H1, H2, H3), and DSCAM (Down's syndrome cell adhesion(More)
Mannitol is a six-carbon sugar alcohol that is widely distributed in plants. Sugar alcohols are widely used in various food products because of their numerous beneficial health effects. The present study investigated the effects of mannitol consumption on digestion, large gut fermentation and nutrient metabolism in normal and cecectomized male Wistar rats.(More)
The hippocampus plays an essential role in learning and memory and is one of the major sites implicated in neural diseases. The proper organization of the hippocampus during development is important for its function. We found that draxin, a repulsive axon guidance cue, was widely expressed in the developing hippocampus and draxin deficient mice possessed a(More)
The mesencephalic V neurons and tectobulbar axons in chick embryo project over long distances that appear during the early development of the chick optic tectum. The mesencephalic V neuron and tectobulbar axonal growth begin at Hamburger and Hamilton stage 14 and stage 18, respectively. Both fibers proceed downward from the dorsal to the ventral side of the(More)
Generation of the appropriate types, numbers and distribution of neurons during the development of the nervous system requires the careful coordination of proliferation, differentiation, and patterning. In this work, we analyzed the roles of a repulsive axon guidance protein, draxin, on the development of chick spinal cord dI3 interneuron. draxin mRNA(More)
staining of acetylcholinesterase, highlighting the myenteric ganglion and its fiber tracts in the ileum of an adult mutant mouse lacking homeodomain-interacting protein kinase 2. For more information, see the article by Chalazonitis et al. in this issue (pages 13746 –13757).
The neural crest is a multipotent population of migratory cells that arises in the central nervous system and subsequently migrates along defined stereotypic pathways. In the present work, we analyzed the role of a repulsive axon guidance protein, draxin, in the migration of neural crest cells. Draxin is expressed in the roof plate of the chick trunk spinal(More)
