Genistein--a dietary compound inducing hormonal and metabolic changes

Genistein is a plant-derived compound possessing well-known preventive activity in breast and prostate cancer, cardiovascular diseases and post-menopausal problems. Lately, the interests in genistein have widened. The studies concerning effects of genistein performed on animals and humans revealed other aspects of its action – the metabolic alterations at the cellular level and in the whole organism. It was shown that genistein decreased body and fat tissue weight gains accompanied by reduced food intake. After ingestion of dietary genistein, the alterations in concentrations of hormones such as: insulin, leptin, thyroid hormones, adrenocorticotropic hormone, cortisol and corticosterone were observed. The changes in lipid parameters – triglycerides and cholesterol were also noticed as a consequence of genistein administration. Moreover, the altered expression of genes engaged in lipid metabolism, disturbed glucose transport into cells, affected lipolysis and lipogenesis and changed ATP synthesis were found as a result of genistein action.
