Effect of D,L-alpha-difluoromethylornithine (DFMO) enhanced [3H]putrescine uptake on 9L tumor cell growth and colony forming efficiency.


PURPOSE This study explored the possible use of D,L- alpha-difluoromethylornithine (DFMO) to enhance the uptake of [3H] putrescine in order to selectively kill brain tumor cells. METHODS AND MATERIALS Gliosarcoma cells (9L) were grown for 4 or 20 day periods in monolayer cultures with or without [3H] putrescine and/or DFMO. Cells in culture incubated for… (More)
