(4,5) The cytoplasmic protein [beta]-catenin (14/[beta]-catenin, BD Biosciences, Erembodegem, Belgium) was evaluated as a first potential candidate because it is a low-molecular weight (88 kDa versus 660 kDa of thyroglobulin) peptide that is involved in adherens junctions, epithelial
contact inhibition signaling, and gene transcription.
