Research Abstract

We have examined whether a new differentiation inducer of leukemic cells can suppress the proliferation of solid tumor cells. We recently found that cotylenin A and rapamycin synergistically inhibited the growth of human mammary cancer cells in vitro and in vivo. In this study we found that the abrogation by cotylenin of the rapamycin-induced feedback activation of Akt signaling contributed, at least in part, to the synergistic growth inhibition of mammary cancer cells induced by treatment with cotylenin A and rapamycin.
