Adipocytic tumors represent the largest single group of soft tissue tumors. In the present study, we investigated the antiproliferative potential of quercetin in SW 872 human liposarcoma cells. Cell viability was significantly influenced by quercetin treatment in a time- and dose-dependent manner. Flow cytometric analyses of SW 872 human liposarcoma cells exposed to quercetin showed that the increase of apoptotic cells was time- and dose-dependent. The percentages of normal cells were decreased and apoptotic cells (including early apoptotic and late apoptotic) were increased with increasing concentrations of quercetin. Quercetin-induced apoptosis in SW 872 human liposarcoma cells was associated with the loss of mitochondrial membrane potential (Delta Psi(m)) The apoptosis in SW 872 human liposarcoma cells induced by quercetin was mediated through the activation of caspase-3, Bax, and Bak and then cleavage of PARP and downregulation of Bcl-2. These results demonstrate that quercetin may prevent atypical lipomatous tumors/well-differentiated liposarcomas from mature adipocytic proliferation, which may contribute to its antiproliferative function.
