Definition / general
  • Part of Wnt signalling pathway, highly conserved pathway with critical role in embryologic development (Dev Cell 2009;17:9), carcinogenesis and epithelial-to-mesenchymal transition
  • Upon Wnt activation, β catenin is translocated from membrane (where it interacts with E-cadherin) to cytoplasm and nucleus, where it interacts with transcriptional activators
Clinical features
  • Mutations and overexpression of β catenin are associated with various carcinomas
  • Colon: plays a critical role in tumorigenesis (mutations in APC or β catenin present in 90% of colon cancers)
  • Thyroid: pathway important for anaplastic and possibly papillary thyroid carciomas (Front Endocrinol (Lausanne) 2012;3:31)
  • Uterus: endometrioid endometrial carcinoma is associated with β catenin mutations
