The patched hedgehog receptor inhibits the transmembrane transducer smoothened by reducing the accessibility of cholesterol locally at the membrane of the primary cilium.

Genetic analyses combining photoconvertible cell signalling reporters with gain- and loss-of function manipulations reveal a novel role for Notch signalling in controlling Hedgehog response in neural progenitor cells.

Proteolysis of lipidated N-terminal peptides that tether Hedgehog morphogens to the surface of source cells is absolutely required for their coupled release and bioactivation in vivo in Drosophila melanogaster.

The seemingly simple, constitutive response of the patched/Ptch1 gene to Hedgehog signaling is in fact regulated by large batteries of context-specific Hedgehog-responsive enhancers in both fly and mouse, allowing tissue-specific tuning of the Hedgehog pathway in animal development and evolution.

Dispatched cleavage, mediated by Furin, regulates Dispatched membrane trafficking and release of Sonic Hedgehog ligand.

Direct interaction between Hedgehog-sending and Hedgehog-receiving cytonemes is a fundamental mechanism for morphogen transfer and gradient establishment.

Hedgehog signaling plays a role in regulating glia gene expression in planarians, pointing to a candidate ancestral and broadly used role for the Hedgehog pathway.

The Hedgehog signalling pathway is a master regulator of lipid metabolic processes and their zonation in the adult liver of mice and humans.

Pharmacologic inhibition of DNA methylation restrains the growth of urothelial carcinoma by subtype conversion through heightened stromal Hedgehog pathway activity.

Hedgehog-pathway activation in adjacent epithelial and stromal cells, but not in epithelial or stromal cells alone, enables the generation of functional de novo hair follicles in unwounded adult mouse skin.
