Cell viability rates of luminal breast cancer cell lines after alternate treatment with chloroform extract of Arrabidaea chica (CEAC) and Tamoxifen (Tam) for 48 hours. T-47D (A) and MCF-7 (B) cell lines were treated with CEAC followed by Tam (1μM) or with Tam (1μM) followed by CEAC (1000 μg/mL). Data are expressed as means ± SD, n = 3. Significance (*p < 0.05, **p < 0.01, ***p < 0.001, ****p < 0.0001) was calculated by one-way ANOVA, and Tukey’s post hoc test. # treatments with DMSO (control) differed from all treatments with CEAC, p < 0.0001
