CCND1 and colorectal carcinoma: We tested the antiproliferative activity and the effects on levels of β-catenin and cyclin D1 protein, as well as CRT (measured using a synthetic β-catenin/TCF-reporter gene [TOPflash]), of a panel of NSAIDs (indomethacin, diclofenac, sulindac sulphide and sulphone, rofecoxib; range 10–600 μM) on SW480 human CRC cells in vitro.
