Aim: To characterize the intracellular signaling mechanisms mediating the synergistic anticancer effects of combined ?-tocotrienol and celecoxib treatment in neoplastic +SA mouse mammary epithelial cells in vitro. Methods: +SA mammary tumor cells in different treatment groups were maintained in serum-free defined media containing 10ng/ml EGF as a mitogen and exposed to various doses of ? -tocotrienol and celecoxib alone or in combination. After a 96 hr culture period, cells were collected and whole cell lysates were subjected to Western blot analysis to determine treatment effects on intracellular signaling proteins associated with EGF-dependent mitogenesis and survival, and prostaglandin synthesis and responsiveness. Results: Treatment with high doses of ?-tocotrienol or celecoxib alone inhibited Akt activation and downstream signaling and NF?B activation. Similar treatment with .. Read More»
