Background: In many types of cancers zinc deficiency and overproduction of Hedgehog (Hh) ligand co-exist. Results: Zinc binds to the active site of the Hedgehog-intein (Hint) domain and inhibits Hh ligand production both in vitro and in cell culture. Conclusion: Zinc influences the Hh autoprocessing. Significance: This study uncovers a novel mechanistic link between zinc and the Hh signaling pathway.
