Figure 6: Armillaridin enhanced radiosensitivity of human esophageal CE81T/VGH cancer cells. CE81T/VGH cells were treated with vehicle (closed circle), AM 1.25  M (opened circle), 2.5  M (closed inverted triangle), or 5  M (opened triangle) for 24 h before radiation. After radiation, drugs were washed out, and cells were cultured for 14 days for colony formation assay. Data from three separate experiments are expressed as mean SE. Significant differences between control cells and cells treated with AM 5  M are indicated by * .
