It has been shown that genistein inhibits many type of cancers including prostate cancer (PCa) by regulating several cell signaling pathways and microRNAs (miRNAs). in vitro: GEN effectively reversed estrogenicity of BPA by reversing mRNA and protein expressions of ERα, IGF-1R, pIRS-1, and pAkt induced by BPA in cellular model and also significantly decreased tumor growth and in vivo expressions of ERα, pIRS-1, and pAkt in xenografted mouse model [1]. Interestingly, genistein and its analogs induced caspase 3-activation supporting apoptotic mechanism of cell death but SPG-G supported caspase 3-independent apoptosis [2]. Of the compounds tested, only genistein selectively inhibited human topo II activity and had an IC50 value of 37.5 ?M [3] in vivo: Genistein significantly decreased the blood levels of total cholesterol, triglycerides, homocysteine and visfatin compared with placebo, while blood adiponectin levels were increased [4]. Leucine and genistein significantly (p<0.05) reduced the number of fights and increased latency to fights in foot shock-induced aggression; it also decreased apomorphine (5mg/kg, i.p.) induced stereotyped behavior and apomorphine induced (10mg/kg, s.c.) locomotor activity when compared with the positive control group [5]. Clinical trial: Cholecalciferol and Genistein Before Surgery in Treating Patients With Early Stage Prostate Cancer. Phase 2
