Materials and methodsThe cell line studied, L1210RR, has a 30-to 40-fold elevation of dihydrofolate reductase (DHFR) and a decreased transport for MTX as compared to the parent line [3]. Both lines are maintained in Fischer’s medium containing 10% horse serum; in addition, the resistant line is also grown in the presence of 10m4M MTX. Growth for 1 year in the absence of MTX has not changed the characteristics or quantity of DHFR or transport properties of the L1210RR line. Details of cell growth and MTX transport of both the parent and resistant line have been presented elsewhere [4].Radiolabeled [r4C] trimetrexate monoacetate, sp. act. 9.4 mCi/mmole, was supplied by Dr. Robert Engel of the National Cancer Institute. Purity was checked by high performance liquid chromatography (HPLC)[5]. The drug was more than 95% pure for all experiments presented. Tritiated MTX (13 Ci/mmole, Amersham-Searle) was purified by HPLC or DEAE cellulose and was 99% pure as detailed [4]. Trimethoxyaniline and 2, 4-diamino-. 5-methyl-6-quinazoline-carbonitrile were obtained from Warner-Lambert.
