PCAE mediates the survival of EC cells through the inhibition of proliferation. Ishikawa cells were treated with increasing doses of PCAE (0, 1, 2 and 4 mg/mL) for 24 to 72 h in vitro. The survival of PCAE-treated cancer cells was measured using the MTT method. Results are expressed as a percentage of the control, which was considered to be 100%. All data are reported as the mean (±SEM) of at least three separate experiments. Statistical analysis was performed using a t-test, with significant differences (p < 0.05) between treatment and control (PCAE 0 mg/mL) groups, and & vs. the 24 h group and # vs. the 48 h group, delineated by the * symbol.
