  • Publication number: 20100069386
    Abstract: The present invention makes available methods and reagents for inhibiting aberrant growth states resulting form hedgehog gain-of-function, ptc loss-of-function or smoothened gain-of-function comprising contacting the cell with a hedgehog antagonist, such as a small molecule, in a sufficient amount to aberrant growth state, e.g., to agonize a normal ptc pathway or antagonize smoothened or hedgehog activity. Such methods and reagents may also inhibit the hedgehog pathway in normal cells, e.g., where normal levels of hedgehog signalling are unwanted.
