AGS cells and SW480 cells were incubated for 3 days with different concentrations of CBD in absence or presence of 2 nM Paclitaxel (AGS) or 10 nM Paclitaxel (SW480). a, c Cell viability was assessed by incubation with AB. The mean + SD of three (AGS) and six (SW480) assays are shown. b, d Before harvesting, cells were incubated for 2 h with BrdU, which incorporated into DNA, and DNA synthesis was quantitated. The mean + SD of three assays (AGS) and 5 assays (SW480) are shown. *p < 0.05
