Morphogenetic Signalling: Responses to Hedgehog [PDF]
Protein kinase A activity is required for signalling by the extracellular molecule Hedgehog in developing Drosophila imaginal discs, but does the kinase actually respond to the Hedgehog signal?

Hedgehog signaling and gastrointestinal cancer
Hedgehog (Hh) signaling is critical for embryonic development and in differentiation, proliferation, and maintenance of multiple adult tissues. De-regulation of the Hh pathway is associated with birth defects and cancer. In the gastrointestinal tract, Hh ligands Sonic (Shh) and Indian (Ihh), as well as the receptor Patched (Ptch1), and transcription ...

Gli2a protein localization reveals a role for Iguana/DZIP1 in primary ciliogenesis and a dependence of Hedgehog signal transduction on primary cilia in the zebrafish [PDF]
Background: In mammalian cells, the integrity of the primary cilium is critical for proper regulation of the Hedgehog (Hh) signal transduction pathway.

Hedgehog Signaling in Endochondral Ossification [PDF]
Hedgehog (Hh) signaling plays crucial roles in the patterning and morphogenesis of various organs within the bodies of vertebrates and insects. Endochondral ossification is one of the notable developmental events in which Hh signaling acts as a master regulator.

Inhibitors of Hedgehog acyltransferase block Sonic Hedgehog signaling [PDF]
Inhibition of Sonic hedgehog (Shh) signaling is of great clinical interest. Here we exploit Hedgehog acyltransferase (Hhat)-mediated Shh palmitoylation, a modification critical for Shh signaling, as a new target for Shh pathway inhibition. A target-oriented high-throughput screen was used to identify small-molecule inhibitors of Hhat.

Mitogen-activated kinase kinase kinase 1 inhibits hedgehog signaling and medulloblastoma growth through GLI1 phosphorylation [PDF]
The aberrant activation of hedgehog (HH) signaling is a leading cause of the development of medulloblastoma, a pediatric tumor of the cerebellum. The FDA‑approved HH inhibitor, Vismodegib, which targets the transmembrane transducer SMO, has shown limited

The Hedgehog Signaling Pathway in Cancer [PDF]
AbstractThe Hedgehog (Hh) pathway is a signaling cascade that directs patterning in most animals and is crucial for proper development. At the molecular level, Hh ligands drive cell proliferation in some cell types while causing others to undergo differentiation. Hh signaling is most active during embryogenesis, and aberrant reactivation of the pathway

Investigating the role of Hedgehog/GLI1 signaling in glioblastoma cell response to temozolomide. [PDF]
Resistance to chemotherapy substantially hinders successful glioblastoma (GBM) treatment, contributing to an almost 100% mortality rate. Resistance to the frontline chemotherapy, temozolomide (TMZ), arises from numerous signaling pathways that are ...
