Basal cell carcinoma (BCC) is driven by constitutive activation of the Hedgehog (Hh) signaling pathway, most commonly through loss-of-function mutations in PTCH1. Using animal models, we demonstrate here that microscopic BCC-like tumors initiated loss Ptch1 or gain Smo fail to progress and eventually enter into a dormant state. Because NOTCH1/2 TRP53 are detected human BCC, sought determine if ...
