5、nduces a dose-dependent inhibitory effect on the invasive capacity of MDA-MB-231 cells that is significant atthe highest concentration tested (50 M). Following 48-h exposure to (R)-Equol, invasion is reduced by 62%(p=0.009, versus untreated cells) with 50 M (R)-Equol. Matrix metalloproteinase-2 (MMP

7、l-fed group issignificantly lower than that of rats treated with S-(-)equol (P=0.008). (R)-Equol-fed animals have 43% fewertumors than the control group and this difference is highly statistically significant (P=0.004). The number oftumors/tumor-bearing animal is significantly lower in the animals f

At necropsy, the mean (SEM) tumor weight per animal for (R)-Equol fedrats (5.31.1 mg) is significantly reduced (P=0.04) when compare with Controls (9.91.4 mg). Feeding the(R)-Equol diet results in significantly increased tumor latenc
