Most cancer tissues showed weak to moderate cytoplasmic and nuclear immunoreactivity. A few cases of melanomas, colorectal and liver cancers were strongly positive.
Moderate cytoplasmic and nuclear staining was observed in most cancer tissues. A majority of gliomas showed strong nuclear staining while squamous cell carcinomas in skin were weakly stained.

Description
Axin 2 (HGNC Symbol)
Entrez gene summary
The Axin-related protein, Axin2, presumably plays an important role in the regulation of the stability of beta-catenin in the Wnt signaling pathway, like its rodent homologs, mouse conductin/rat axil. In mouse, conductin organizes a multiprotein complex of APC (adenomatous polyposis of the colon), beta-catenin, glycogen synthase kinase 3-beta, and conductin, which leads to the degradation of beta-catenin. Apparently, the deregulation of beta-catenin is an important event in the genesis of a number of malignancies. The AXIN2 gene has been mapped to 17q23-q24, a region that shows frequent loss of heterozygosity in breast cancer, neuroblastoma, and other tumors. Mutations in this gene have been associated with colorectal cancer with defective mismatch repair. [provided by RefSeq, Jul 2008]
