WebFeb 20, 2004 · As a result, β-catenin accumulates in the cytoplasm, and presumably, this leads to translocation of this protein into the nucleus where it interacts with the DNA-binding T-cell factor complex and acts as a transcriptional activator, thus turning on target genes, including c- myc and cyclin D1 in the case of colorectal cancer (9, 10). WebAll other lesions tested (n=67) lacked nuclear labeling for beta-catenin, showing only cytoplasmic accumulation. beta-Catenin immunohistochemistry separates deep …
WebSep 1, 2000 · Concerning localization of β-catenin in mesenchymal tissues, Kim et al. reported a cytoplasmic distribution of β-catenin in fibroblasts without significant amounts at the cell surface. WebBeta-catenin is involved in cellular cohesion through binding to the cytoplasmic tail of E-cadherin, and in intracellular signaling as a component of the Wnt pathway. In normal cells, B-catenin levels are regulated by the adenomatous polyposis coli (APC) protein, which promotes normal degradation of the protein.
