Elevated β‐catenin levels were observed in several tumor samples (T3, T12, T13, T16, T18, T20, T21, T25, T35, T46, and T52) compared to their corresponding peritumoral tissues, particularly in samples harboring CTNNB1 mutations at phosphorylation sites (Figure 6a). Here, CTNNB1 is linked to neoplasm.
