Abstract excerpt
In normal epithelial cells, transforming growth factor-beta (TGF-beta) typically causes growth arrest in the G(1) phase of the cell cycle and may eventually lead to apoptosis. However, transformed cells lose these inhibitory responses and often instead show an increase in malignant character following TGF-beta treatment. In the canine kidney-derived epithelial cell line, MDCK, synergism between activation of the...
