... recent publications, we review two in vivo derived concepts of regulated gradient formation of the morphogen Hedgehog (Hh). In the first concept, Hh disperses on the apical side of developing epithelial surfaces using the same mechanistic adaptations of molecular transport that DNA-binding proteins...

...Kristina Ehring; Kay Grobe Vertebrate and invertebrate Hedgehog (Hh) morphogens signal over short and long distances to direct cell fate decisions during development and to maintain tissue homeostasis after birth. One of the most important questions in Hh biology is how such Hh signaling to distant...

... and Alzheimer's disease; in signalling and development, in particular, in relation to Hedgehog signalling; and in cancer, with a special focus on (25R)26-hydroxycholesterol. Methods for the measurement of oxysterols, essential for understanding their mechanism of action in vivo , and valuable for diagnosing rare...

... ]. Figure 1. Development of the mandible and Hedgehog signaling at the cilium. ( A ) Early embryonic stages of mandibular development. ( A ) Lateral view of head, E9.5. Earlier, at E8.5, the neural crest cells (Ncc, gray arrows) emerge from the dorsal neural tube populating the facial prominences by E9.5...

..., the Wnt, Hedgehog (Hh) and Ghrelin proteins. Given their important roles in adult tissue homoeostasis, all three molecules and their respective associated acyltransferases provide a framework for interrogating the role of extracellular acylation events in cell-to-cell communication. Here, we discuss how...

...D. Kalderon 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...
