Tannic Acid Preferentially Targets Estrogen Receptor-Positive Breast Cancer

Figure 4

Tannic acid exposure induces apoptosis in breast cells. (a) MCF10A, (b) MDA-MB-231, and (c) MCF7 cells were untreated or treated with 10%, 1.0%, and 0.1% TA cross-linked beads for 24–48 h. TUNEL assays were performed and the results displayed as the percentage of apoptotic cells. 𝑛=3, ^∗𝑃<0.05 versus ^∗∗𝑃<0.05 and error bars = SE. NT: no treatment.
