HEDGEHOG SIGNALING PROTEIN [2 records]

Record 1 2010-04-20

English

Subject field(s)
  • Genetics
CONT

Sending and receiving the Hedgehog signal: control by the Drosophila Gli protein cubitus interruptus.

CONT

The ptc gene encodes a transmembrane protein that in Drosophila acts in opposition to the Hedgehog signaling protein, controlling cell fates, patterning, and growth in numerous tissues. The human PTC gene appears to be crucial for proper embryonic development and for tumor suppression.

CONT

[...] le système de transmission du signal Hedgehog est à l'honneur. Son régulateur négatif, Patched, est déficient dans le syndrome de Gorlin et des épithéliomas baso-cellulaires sporadiques. L'une des cibles du signal Hedgehog est le facteur Wingless/Wnt1, lui même impliqué dans la régulation de la prolifération et de la morphogénèse. Ce facteur agit en contrôlant la quantité et l'activité de la ß-caténine [...]

Record 2 2010-04-20

English

Subject field(s)
  • Genetics
DEF

A growth factor that can (at least in a Petri dish) transform stem cells into mature dopamine producers.

CONT

Ontogeny researchers are shooting sonic hedgehog directly into the brains of mice. Men will come later.

CONT

The protein Sonic Hedgehog (Shh) controls patterning growth during vertebrate development. Here we demonstrate that it binds Patched (vPtc), which has been identified as a tumour-suppressor protein in basal cell carcinoma, with high affinity.

CONT

The segment polarity gene, hedgehog(hh) encodes a novel signaling protein that mediates local cell-cell interactions in the developing Drosophila embryo. Here we describe the existence of an hh-related gene family in the zebrafish. Brachydanio rerio. One of these genes, sonic hedgehog(shh) is expressed in the notochord, floor plate and posterior fin mesoderm tissues associated with polarizing activities in various vertebrate embryos.

CONT

Sonic Hedgehog est un morphogène dont l'importance dans le développement des invertébrés a récemment été illustré par un grand nombre d'articles dont «Médecine/Sciences» s'est fait l'écho.
