Abstract: A method for reducing pulmonary hypertension in a mammal that employs FK506 is provided. In certain embodiments, the method comprises administering FK506 to a mammal having pulmonary arterial hypertension associated with defective MBPR2 signaling at a dosage sufficient to reduce blood pressure in the pulmonary artery of the mammal.

Abstract: Provided is a conformation-specific antigen binding domain (ABD) specific for the Hedgehog receptor Patched1, which may be provided in the form of a nanobody. This nanobody potently activates the Hedgehog pathway in vitro and in vivo by stabilizing an alternative conformation of a Patched1 “switch helix”. This ABD or nanobody is water soluble, i.e. does not require lipid modifications for its activity, facilitating mechanistic studies of Hedgehog pathway activation and therapeutic use.

Abstract: The present invention makes available, inter alia, methods and reagents for modulating smoothened-dependent pathway activation. In certain embodiments, the subject methods can be used to counteract the phenotypic effects of unwanted activation of a hedgehog pathway, such as resulting from hedgehog gain-of-function, ptc loss-of-function or smoothened gain-of-function mutations.

Abstract: The present invention makes availables assays and reagents inhibiting paracrine and/or autocrine signals produced by a hedgehog protein or aberrant activation of a hedgehog signal transduction pathway, e.g., which involve the use of a steroidal alkaloid or other small molecule.

Abstract: Methods of transdermally delivering a therapeutic amount of a triazole-triazolone compound are provided, e.g. for the prevention or treatment of basal cell carcinoma (BCC) in a subject. A therapeutic level of a triazole-triazolone compound such as itraconazole is delivered transdermally to a subject. Also provided are topical triazole-triazolone compositions that find use in practicing the subject methods.

Abstract: The present invention provides two novel polypeptides, referred to as the “N” and “C” fragments of hedgehog, or N-terminal and C-terminal fragments, respectively, which are derived after specific cleavage at a G?CF site recognized by the autoproteolytic domain in the native protein. Also included are sterol-modified hedgehog polypeptides and functional fragments thereof. Methods of identifying compositions which affect hedgehog activity based on inhibition of cholesterol modification of hedgehog protein are described.

Abstract: The present invention sterol-modified hedgehog polypeptides and functional fragments thereof. Methods of identifying compositions which affect hedgehog activity based on inhibition of cholesterol modification of hedgehog protein are described. In one aspect of the invention, the method provides a means for affecting cholesterol biosynthesis or transport in a cell comprising contacting a cell with an effective amount of a compound that affects hedgehog, thereby affecting cholesterol biosynthesis or transport. The effect may be inhibition or stimulation of cholesterol biosynthesis or transport.
