Web8 Apr 2024 · Approximately 20~25% of CTNNB1, encoding β-catenin, ~10% of AXIN1, and ~3% of AXIN2, are mutated [ 37, 38 ]. Additionally, FZD3, FZD6, and FZD7 receptors, Wnt 3, Wnt4, Wnt 5A ligands, and the modulator RSPO2 are frequently overexpressed or amplified in HCC [ 39 ]. WebAXIN1 gene, being a negative regulator of the Wnt/β-catenin signal pathway, undergoes loss-of-function mutations. Research has shown that AXIN1 mutations occur independently of Wnt/β-catenin pathway and they correlate with Notch and YAP pathways which can represent interesting targets in HCC treatment . map of littleton new hampshireWebMutations that involve the β-catenin gene and the AXIN1/2 gene result in sustained aberrant activation of the Wnt/β-catenin pathway and thus dysregulate multiple cellular functions, including proliferation, apoptosis, and cell motility. 1,3,7,19,31–33 Mutations in CTNNB1 can result in the production of β-catenin proteins that are resistant ... kroger troy ohio phone
