Effect of ARE treatment on tumor growth and myelosuppression in BALB/c breast cancer mice with DOX chemotherapy. Comparisons of (A) the tumor size (a) and quantified tumer weight (b); and (B) blood cell staining (a) and quantified blood cell count (b) among BALB/c breast cancer mice with the Sham, ARE (150 mg/kg), DOX (2.4 mg/kg), and ARE (150 mg/kg) + DOX (2.4 mg/kg) treatments. ARE treatment alleviated tumor growth and myelosuppression induced by DOX chemotherapy in the BALB/c breast cancer mice (N = 8 for each group; values are presented as the mean ± SEM, ** p < 0.01, * p < 0.05, one-way ANOVA followed by the Student–Newman–Keuls multiple comparisons post hoc test). Scale bar = 100 μm.
