Abstract
Although pituitary tumors are mostly benign they share certain molecular events with more malignant neoplasia although their precise pathogenesis is far from established The acquisition of new functional characteristics during their evolution suggests a multistep process that leads to tumor transformation Mutations in classical tumor suppressor genes or oncogenes are infrequently associated with pituitary tumorigenesis However alterations in different signaling pathways especially those involved in pituitary gland development have emerged as significant features in pituitary adenomas In particular changes in inhibitory components of the βcatenin pathway and its relationship to the cadherin family of peptides may well play an important role in tumorigenesis We review and assess the role of the βcatenin signaling pathway in the pathogenesis of pituitary adenomas
