tocotrienol-rich fraction
An orally available nutritional supplement containing high amounts of the vitamin E family member tocotrienol with antioxidant, hypolipidemic and potential immunomodulating and antiproliferative activity. Upon oral administration, tocotrienol-rich fraction (TRF) accumulates in tumor cells and induces cell cycle arrest, programmed cell death, and inhibits tumor cell proliferation. In addition, this agent suppresses 3-hydroxy-3-methylglutaryl coenzyme A (HMG CoA) reductase activity and inhibits angiogenesis. Rice bran oil, palm oil and annatto seed oil are common sources of TRF. Check for active clinical trials using this agent. (NCI Thesaurus)
