Fig. 2: The inhibitory effect of cordycepin, cDDP, and combination therapy on the proliferation of esophageal cancer cells.

Cordycepin, cDDP, and combination therapy inhibited the proliferation of esophageal cancer cells as shown by decreased cell viability (A, C, E, G). The drug concentration-cell viability curve was generated as a percentage of viable cells. The synergistic effect between cordycepin and cDDP is represented by a Fa-CI diagram (B, D, F, H). The above data are from three replicate experiments in quadruplicate wells (mean ± SD). Compared with the control group, *p < 0.05, **p < 0.01 or ***p < 0.001. cDDP cisplatin, Cor cordycepin.
