Gamma-secretase inhibition combined with platinum compounds enhances cell death in a large subset of colorectal cancer cells.
BACKGROUND: Notch signalling is essential for the development and maintenance of the colonic epithelium. Its inhibition induces a differentiation phenotype in vivo and reduces adenomas in APCmin mice. Whether Notch signals are also required in colorectal cancer (CRC) has remained elusive. Therefore, 64 CRC cell lines were analysed for the occurrence of proteolytically processed, active Notch. RESULTS: 63 CRC lines contained a fragment with approximately the size of the Notch1 intracellular d...Expand abstract
