Background: The sonic hedgehog pathway (SHH) regulates CNS development and mutations or abnormal expression of the SHH pathway genes have been identified in epithelial tumors. SHH pathway interacts with Wnt/β-catenin signalling. To date, CTNNB1/β-catenin mutations are the sole molecular abnormality found in adamantinomatous craniopharyngiomas (ACPs).Objective and Hypotheses: To analyze the expression pattern of SHH pathway genes in ACPs and its...
