Hedgehog 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 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...
متن کاملHedgehog signal transduction: from flies to vertebrates.
The patterning and morphogenesis of multicellular organisms require a complex interplay of inductive signals which control proliferation, growth arrest, and differentiation of different cell types. A number of such signaling molecules have been identified in vertebrates and invertebrates. The molecular dissection of these pathways demonstrated that in vertebrates, mutations or abnormals functio...
متن کاملNeuropilins are positive regulators of Hedgehog signal transduction.
The Hedgehog (Hh) pathway is essential for vertebrate embryogenesis, and excessive Hh target gene activation can cause cancer in humans. Here we show that Neuropilin 1 (Nrp1) and Nrp2, transmembrane proteins with roles in axon guidance and vascular endothelial growth factor (VEGF) signaling, are important positive regulators of Hh signal transduction. Nrps are expressed at times and locations o...
