Of the mammary gland, the integrin receptor- and steroid hormone-signaling pathways play an important role. Disruption of the delicate balance of signaling can result in dramatic changes in the cellular interactions, which might lead to breast cancer [Hansen and Bissell 2000]. The adhesion receptors of the integrin family are transmembrane receptors consisting of an α- and a β-subunit and exert important functions in signal transduction via the actin cytoskeleton [Wiesner et al. 2005, Dedhar and Hannigan 1996, Nebe et al.
In the context of the present work, we have developed a method for the determination of free daidzein and genistein in the urine by means of HPLC (high performance liquid chromatography with UV detection) as well as of conjugated daidzein and genistein after splitting of the conjugates by means of acid hydrolysis. 492 urine samples of 80 participants in the “randomized placebo-controlled double-blind study on the realization of osteoporosis prophylaxis and relief of climacteric complaints using nutrient-enriched food” of the Department of Obstetrics and Gynecology of the University Rostock were examined for their content of isoflavones.
It can be postulated, dietary intervention with isoflavone supplementation may have biologic activity in men with biochemical active prostate cancer as shown by a decline in the slope of PSA in pilot studies. Pendleton et al. [2008] evaluated the efficacy of isoflavones in patients with PSA recurrent prostate cancer after prior therapy. They postulated that isoflavone therapy would 36 Volker Briese, Sibylle Abarzua, Dagmar-Ulrike Richter et al slow the rate of rise of serum PSA. Twenty patients with rising PSA after prior local therapy were enrolled in this open-labeled, Phase II, nonrandomized trial.
