Arabinosylguanine-induced apoptosis of T-lymphoblastic cells : Incorporation into DNA is a necessary step

9-Beta-D-Arabinosylguanine (ara-G) is a recently introduced and effective treatment for T-cell acute lymphoblastic leukemia, but how ara-G and ara-G triphosphate (ara-GTP) kill cells is not known. We hypothesized that, in cycling T-lymphoblastoid cells, ara-G may act directly by incorporation into D...
