Title: Resistance and cross-resistance of cultured leukemia P388 cells to vincristine, adriamycin, adriamycin analogs, and actinomycin D. Author: Wilkoff LJ, Dulmadge EA. Journal: J Natl Cancer Inst; 1978 Dec; 61(6):1521-4. PubMed ID: 281559. Abstract: Cultured P388 cells derived from leukemia P388 passaged in vivo in (C57BL X DBA/2)F1 mice were approximately one-tenth less sensitive to N-trifluoroacetyladriamycin-14-valerate (AD32) and cinerubin A, inasmuch as the concentrations of these agents had to be increased tenfold to produce a reduction in cell viability of the same order of magnitude as that produced by adriamycin, daunomycin, or actinomycin D. Cultured P388 cells derived from resistant cell populations developed in vivo retained their resistance to vincristine. These resistant cells exhibited cross-resistance to actinomycin D, adriamycin, daunomycin, and AD32, but cross-resistance to cinerubin A could not be detected. Data also showed that the vincristine-resistant cells were more sensitive to AD32 (2.8 x 10(-6) M) than to adriamycin (3.4 x 10(-6) M) during a 6-hour exposure of cells to agents.[Abstract] [Full Text] [Related] [New Search]
