The classical Hedgehog signaling pathway involves glycoproteins that are secreted by cells into the intercellular space. Multiple such glycoproteins have been characterized: Sonic Hedgehog (Shh), Indian Hedgehog (Ihh), and Desert Hedgehog (Dhh). [16] Among these, Shh is the most potent.
Sonic hedgehog has been shown to promote the proliferation of adult stem cells from various tissues, including primitive hematopoietic cells, [32] mammary [33] and neural [34] stem cells. Activation of the hedgehog pathway is required for transition of the hair follicle from the resting to the growth phase. [35]
A potential inhibitor of the Hedgehog signaling pathway has been found and dubbed "Robotnikinin"—after Sonic the Hedgehog's nemesis and the main antagonist of the Sonic the Hedgehog game series, Dr. Ivo "Eggman" Robotnik. [89]
PTCH1 is a member of the patched gene family and is the receptor for sonic hedgehog, a secreted molecule implicated in the formation of embryonic structures and in tumorigenesis. This gene functions as a tumor suppressor .
Sonidegib is a Hedgehog signaling pathway inhibitor (via smoothened antagonism). [5] [6] Approvals and indications.
Vismodegib, sold under the brand name Erivedge, is a medication used for the treatment of basal-cell carcinoma (BCC). [3] The approval of vismodegib on January 30, 2012, represents the first Hedgehog signaling pathway targeting agent to gain U.S. Food and Drug Administration (FDA) approval. [4]
Helmed at a breakneck pace by Jeff Fowler, “Sonic the Hedgehog 3” is loud, chaotic and often corny, with a visual style that can only be described as “retina-searing,” but the script by ...
Four decades later, a team led by Professor Phillip Beachy linked the effect of cyclopamine to the sonic hedgehog gene. Cyclopia was induced through silencing the sonic hedgehog gene, suggesting Cyclopamine acted through a similar mechanism.
