Abstract |
Phloretin, a naturally occurring dihydrochalcone, is known to inhibit tumor cell growth in vitro and in vivo. To clarify the anti-tumor effects of phloretin, its apoptosis-inducing effects in B16 melanoma 4A5 cells were examined. Phloretin induced the internucleosomal DNA fragmentation typical of apoptosis in B16 melanoma cells. The addition of extracellular glucose remarkably inhibited the phloretin-induced apoptosis in the cells. When apoptosis was strongly induced in the B16 cells by phloretin, protein kinase C activity was inhibited in the cells. Our results suggest that phloretin induced apoptosis in B16 melanoma 4A5 cells mainly through the inhibition of glucose transmembrane transport. Inhibition of protein kinase C activity by phloretin probably promotes the ratio of apoptotic cells in the cells.
