CTS facilitates esophageal cancer cell apoptosis.

Notes: EC109 and CAES17 cells were treated with CTS (0, 1, 2.5, 5, 10 and 20 µmol/L) for 48 hours. (A, B) CTS-treated esophageal cancer cells were stained with annexin V–FITC/PI and analyzed by flow cytometry. Percentages of survival and early and late apoptotic cells are presented as mean ± SD (n=3). *P<0.05, **P<0.01 vs the control group.

Abbreviations: CTS, cryptotanshinone; FITC, fluorescein isothiocyanate; PI, propidium iodide; PE, phycoerythrin.
