8-Cl-adenosine inhibits growth in colorectal cancer cells in a dose-dependent manner. Selected colorectal cancer cells were treated for 72 hours with various concentrations of 8-Cl-adenosine. The amount of incorporated 3H-thymidine was determined as described in Materials and Methods. Data represent the average±SEM, n=3. *p<0.05, comparing HCT116 to HCT116-E6 at 0.1 µM.
