Abstract (original English)
In the present study, we investigated the role of the phytoestrogen genistein and 17beta-estradiol in human bone marrow stromal cells, undergoing induced osteogenic or adipogenic differentiation. Profiling of estrogen receptors (ERs)-alpha, -beta1, -beta2, -beta3, -beta4, -beta5, and aromatase mRNAs revealed lineage-dependent expression patterns. During osteogenic differentiation, the osteoblast-determining core binding factor-alpha1 showed a progressive increase, whereas the adipogenic regulator peroxisome proliferator-activated receptor gamma (PPARgamma) was sequentially decreased. This temporal regulation of lineage-determining marker genes was strongly enhanced by genistein during the early osteogenic phase. Moreover, genistein increased alkaline phosphatase mRNA levels and activity, the osteoprotegerin:receptor activator of nuclear factor-kappaB ligand gene expression ratio, and the expression of TGFbeta1. During adipogenic differentiation, down-regulation in the mRNA levels of PPARgamma and CCAAT/enhancer-binding protein-alpha at d 3 and decreased lipoprotein lipase and adipsin mRNA levels at d 21 were observed after genistein treatment. This led to a lower number of adipocytes and a reduction in the size of their lipid droplets. At d 3 of adipogenesis, TGFbeta1 was strongly up-regulated by genistein in an ER-dependent manner. Blocking the TGFbeta1 pathway abolished the e
