Transducing the Hedgehog Signal
ates Ptc from Smo (Figure 1B) is also generally enter-Daniel Kalderon* tained (Chen and Struhl, 1996) because it is countered Department of Biological Sciences only by a single observation of Ptc-mediated binding of Columbia University Hh to Smo in tissue culture cells that expressed high New York, New York 10027 levels of both vertebrate Ptc and Smo (Stone et al., 1996). Some new data support ...
متن کاملHedgehog signal transduction: recent findings.
The Hedgehog (Hh) family of signaling molecules are key agents in patterning numerous types of tissues. Mutations in Hh and its downstream signaling molecules are also associated with numerous oncogenic and disease states. Consequently, understanding the mechanisms by which Hh signals are transduced is important for understanding both development and disease. Recent studies have clarified sever...
متن کاملFrontiers in hedgehog signal transduction.
The hedgehog (Hh) pathway is a paracrine cell–cell communicaion system discovered in Drosophila over thirty years ago and then tudied for its central role in development in both vertebrates and nvertebrates. Hh was later implicated in other processes, includng adult stem cell maintenance, cell migration, axon guidance and ancer, in a wide range of organisms. Its identification as an oncoenic dr...
متن کاملThe hedgehog pathway and neurological disorders.
The hedgehog pathway is a major regulator of embryonic development, and mutations that decrease its activity are known to be associated with severe defects in nervous system development. Recent evidence suggests hedgehog continues to function in adult tissue, normal as well as diseased, by regulating both cell proliferation and the production of growth and angiogenic factors. In the adult nervo...
متن کاملThe mechanism of hedgehog signal transduction.
Hedgehog (Hh) proteins are one of a small number of families of secreted signalling proteins that are responsible for cell interactions during development in many animals. As such, Hh signals produce many different responses at different times and in different cells. As for other multifunctional ligands, this requires regulated patterns of expression, special mechanisms for ligand movement betw...
