Sensitivity of cell lines to anticancer drugs, observed by quantification of the drug IC₅₀ values for the three cell lines.

	IC50 value
Drug	Tca8113/ut	Tca8113/CBPTca8113/PYM
CBP (µg/ml)	6.99±0.34	22.63±0.15a	28.02±0.17b,c
PYM (µg/ml)	1.19±0.27	15.29±0.26a	14.16±0.08b,c
Paclitaxel (nM)	1.07±0.14	6.35±0.24a	4.69±0.11b,c
Doxorubicin (µg/ml)	3.54±0.13	4.48±0.19a	5.45±0.23b,c

^aP<0.05 vs. Tca8113/ut

^bP<0.05 vs. Tca8113/ut

^cP<0.05 vs. Tca8113/CBP. Data are presented as the mean ± standard deviation of three independent experiments for each cell line. IC₅₀, 50% inhibiting concentration; ut, untreated; CBP, carboplatin; PYM, pingyangmycin.
