Developmental pathways: Sonic hedgehog-Patched-GLI.
Developmental pathways are networks of genes that act coordinately to establish the body plan. Disruptions of genes in one pathway can have effects in related pathways and may result in serious dysmorphogenesis or cancer. Environmental exposures can be associated with poor pregnancy outcomes, including dysmorphic offspring or children with a variety of diseases. An important goal of environment...
متن کاملDual Roles for Patched in Sequestering and Transducing Hedgehog
Secreted proteins of the Hedgehog (Hh) family have diverse organizing roles in animal development. Recently, a serpentine protein Smoothened (Smo) has been proposed as a Hh receptor. Here, we present evidence that implicates another multiple-pass transmembrane protein, Patched (Ptc), in Hh reception and suggests a novel signal transduction mechanism in which Hh binds to Ptc, or a Ptc-Smo comple...
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 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 کاملHedgehog, meet Patched
H edgehog protein and its receptor are made for each other, but even this perfect couple needs a little help to get together. Li et al. (1) reveal that a proteoglycan plays cupid for the molecules and sparks signal transduction through the Hedgehog pathway, a mechanism exploited by a type of childhood cancer. During development, Hedgehog proteins are sculptors, helping to mold the embryo’s limb...
