The WNT/Beta-catenin pathway in melanoma
Frontiers in Bioscience, 2006The Wnt/beta-catenin pathway is involved in various cellular activities--including determination, proliferation, migration and differentiation--in embryonic development and adult homeostasis. The deregulation or constitutive activation of the Wnt/beta-catenin pathway may lead to cancer formation.

beta-catenin-cell adhesion and beyond (review)
International Journal of Oncology, 1997beta-catenin was originally identified as a cytosolic cell protein required for the correct function of the cadherin cell-cell adhesion complex. However, recent studies have identified the presence of intracellular pools of beta-catenin that are cadherin-independent and that beta-catenin is also involved in Wnt-1, src and Tcf-Lef mediated intracellular

Cytokine & growth factor reviews, 2000
The Wnt/Wingless signaling transduction pathway plays an important role in both embryonic development and tumorigenesis. beta-Catenin, a key component of the Wnt signaling pathway, interacts with the TCF/LEF family of transcription factors and activates transcription of Wnt target genes.

HIF-2alpha enhances beta-catenin/TCF-driven transcription by interacting with beta-catenin.
Cancer research, 2011The tumor-promoting factors β-catenin and hypoxia-inducible factor (HIF) are often found to be coactivated in rapidly growing tumors. Recently, it was shown that HIF-1α negatively regulates Wnt/β-catenin signaling by sequestering β-catenin from β-catenin/T-cell factor (TCF).

Beta-catenin undergoes both serine and tyrosine phosphorylation. Serine phosphorylation in the amino terminus targets beta-catenin for proteasome degradation, whereas tyrosine phosphorylation in the COOH terminus influences interaction with E-cadherin.

Science's STKE : signal transduction knowledge environment, 2006
Wnts are secreted glycoproteins that act as ligands to stimulate receptor-mediated signal transduction pathways in both vertebrates and invertebrates. Activation of Wnt pathways can modulate cell proliferation, survival, cell behavior, and cell fate in both embryos and adults.

The APC gene is mutated in the majority of colorectal tumors. The product of this gene is a 300 kDa protein associated with beta-catenin and the human homolog of the Drosophila tumor suppressor DLG. The study of the function of APC provides important insights into the mechanisms of the development of colorectal tumor.

Beta‐catenin and axis formation in planarians
BioEssays, 2009AbstractIn three recent articles it was shown that β‐catenin is crucial for the establishment and the maintenance of the overall polarity and especially for the character ‘posterior’ in planarians. If the transcription of the β‐catenin gene was silenced by RNA interference, the overall polarity is lost, and in regenerating fragments a posterior ...

Beta-catenin is a 92-kDa protein first identified as a molecule associated with the cytoplasmic tail of E-cadherin, as it links E-cadherin to the cytoskeleton. It is a key element in the WNT pathway. In the cytoplasm, beta-catenin forms a complex together with adenomatous polyposis coli (APC) tumor suppressor protein, axin and GSK3beta.

Signal transduction of beta-catenin.
Current opinion in cell biology, 1996Beta-catenin participates in signal transduction and developmental patterning in Xenopus and Drosophila embryos as a component of the Wnt signaling pathway. Its signaling activity is distinct from its role in cadherin-mediated cell adhesion, and it probably acts either in the cytosol or in the nucleus.
