The Hedgehog Knows Many Tricks

Contrary to the Classical Greek poet Archilochus' phrase “The fox knows many things but the hedgehog knows one big thing”, the Hedgehog (HH) signaling pathway knows at least 3 ways to promote or support carcinogenesis. In this review, we provide a summary of the HH signaling pathway, and detail the clinical relevance and treatment of patients. Finally, future directions in exploiting this promising pathway will be addressed.
