Table 3. IC₅₀ of MO and DOX and their combinations on breast cancer cell line.

Treatment	IC50 μg/mL
MO	21.7 ± 0.12b
DOX	0.818 ± 0.01a
MO+DOX	0.425 ± 0.02a

IC₅₀, concentration of drug needed to inhibit cell viability by 50%.

Data are presented as mean ± S.E.M. of three triplicate experiments. Significance was determined by ANOVA followed by Dunnett's t test:

^a P<0.05 vs. MO;

^b P<0.05, vs. MO+DOX.
