    Abstract:
    BACKGROUND: The estrogen-like soy isoflavone genistein can suppress the growth of a number of different types of cancer cells, but its effect on uterine sarcoma is unknown. MATERIALS AND METHODS: The impact of genistein on the proliferation of three uterine sarcoma cell lines, MES-SA, MES-SA-Dx5 and SK-UT-1, was evaluated. TOPflash luciferase reporter assay and western blotting were used to assess the influence of genistein on cellular signaling; DNA fragmentation was assessed as a measure of genistein-induced apoptosis. RESULTS: Genistein inhibited the proliferation of all three cell lines, with half-maximal inhibitory concentrations of 19.2 μM, 13.1 μM and 9.3 μM for SK-UT-1, MES-SA-Dx5, and MES-SA, respectively. This inhibitory activity was accompanied by induction of DNA fragmentation at 48 h. Western blot analyses revealed three major expression patterns: induction of p53 and Dickkopf-related protein 1 (DKK1) and suppression of histone deacetylase 4/5/7 (HDAC4/5/7), dishevelled protein (DVL), BAX, survivin and phosphorylated mitogen-activated protein kinase kinase (phospho-MEK) in all three lines; suppression of p27 and β-catenin in the more resistant lines MES-SA-Dx5 and SK-UT-1; and suppression of Protein kinase B (AKT) and extracellular signal-regulated kinases (ERKs) phosphorylation and activation of caspase-3 in the parental derived lines MES-SA and MES-SA-Dx5. Down-regulation of β-catenin expression also coincided with decreases in TOPflash activity. CONCLUSION: Genistein reduces sarcoma cell numbers through inhibition of proliferative signaling and through induction of programmed or non-programmed cell death. Genistein-mediated signaling changes were unique in each individual cell line, and the differential signaling responses in these three cell lines may contribute to their different levels of susceptibility to this compound.
