Tannic Acid Preferentially Targets Estrogen Receptor-Positive Breast Cancer

Figure 5

Tannic acid exposure induces apoptosis in breast cells via induction of caspases. MCF10A, MDA-MB-231, and MCF7 cells were untreated or treated with 10%, 1.0%, and 0.1% TA cross-linked beads for 24 and 48 h. Levels of activated (a) caspase 9 and (b) caspase 3/7 were determined using flow cytometry. NT: no treatment. TA 10 versus other treatments, MCF7 versus MCF10A.
