| Abstract |
Sodium-dependent amino acid transport of methylaminoisobutyric acid (MeAIB) in a human myelogenous leukemic cell line K562 was inhibited by 30 nM etoposide (VP-16). Cell growth in suspension was almost completely suppressed by 30 nM VP-16 after 72 h. Colony formation by K562 cells markedly decreased after 24 h in a culture medium containing 30 nM VP-16, whereas MeAIB transport was inhibited after 72 h. K562 cell proliferation was restored in drug-free medium after recovery from 72-h culture with 30 nM VP-16. Colony formation and MeAIB transport were restored to pretreatment levels after 1-2 weeks. Thus, two conclusions may be drawn. (1) MeAIB transport may be correlated with cellular growth and (2) the effects of VP-16 on MeAIB transport were partially reversible.
