Sonic hedgehog signaling in Basal cell nevus syndrome.

Sonic hedgehog signaling in basal cell carcinomas.

The development of basal cell carcinoma, the commonest human cancer in fair skinned populations, is clearly associated with constitutive activation of sonic hedgehog signaling. Insight into the genesis of BCC came from the identification of germline mutations of the tumor suppressor gene, PATCHED, a key regulatory component of hedgehog signaling in the nevoid basal cell carcinoma syndrome. Anal...

Craniofacial anomalies: Clinical and molecular perspectives.

The first three disorders discussed are abnormalities of bone: too little bone in cleidocranial dysplasia caused by mutations in RUNX2; too much bone in fibrodysplasia ossificans progressiva with overexpression of BMP4; and abnormal bone in McCune-Albright syndrome and fibrous dysplasia caused by mutations in GNAS1. Disorders of the sonic hedgehog signaling network are discussed next, including...

Basal cell carcinomas in mice overexpressing sonic hedgehog.

Mutations in the tumor suppressor gene PATCHED (PTC) are found in human patients with the basal cell nevus syndrome, a disease causing developmental defects and tumors, including basal cell carcinomas. Gene regulatory relationships defined in the fruit fly Drosophila suggest that overproduction of Sonic hedgehog (SHH), the ligand for PTC, will mimic loss of ptc function. It is shown here that t...

Ingenol Mebutate Treatment in a Patient with Gorlin Syndrome.

BACKGROUND Gorlin syndrome, also known as the basal cell nevus syndrome (OMIM #109400), is a rare autosomal-dominant genetic disease. The disease, which shows mutation of the patched receptor gene (PTCH1) of the sonic hedgehog pathway, is characterized by developing multiple basal cell carcinomas (BCCs) in adolescent patients. Other clinical features include mandibular keratocysts, palmar and p...
