PEBP suppressed the growth of mammary carcinoma cell lines. Proliferation of 4T1 (a), MDAMB-231 (b), and MCF-7 (c) cells after treatment with either 150 or 200 μM GAE (gallic acid equivalent) of either polyphenol-enriched blueberry preparation (PEBP) or normal blueberry juice (NBJ) for 24 h. All values are means of 3 separated experiments ±SEM. *Denotes statistical significance at p ≤ 0.05 vs. control. **Denotes p ≤ 0.01 vs. control
