1 4beta-Phorbol 12-myristate 13-acetate (TPA) increases the number of colonies resistant to methotrexate (MTX), mainly by amplification of the dihydrofolate reductase (dhfr) locus. Tetradecanoylphorbol Acetate dihydrofolate reductase Cricetulus griseus
2 4beta-Phorbol 12-myristate 13-acetate (TPA) increases the number of colonies resistant to methotrexate (MTX), mainly by amplification of the dihydrofolate reductase (dhfr) locus. Tetradecanoylphorbol Acetate dihydrofolate reductase Cricetulus griseus
3 4beta-Phorbol 12-myristate 13-acetate (TPA) increases the number of colonies resistant to methotrexate (MTX), mainly by amplification of the dihydrofolate reductase (dhfr) locus. Tetradecanoylphorbol Acetate dihydrofolate reductase Cricetulus griseus
4 4beta-Phorbol 12-myristate 13-acetate (TPA) increases the number of colonies resistant to methotrexate (MTX), mainly by amplification of the dihydrofolate reductase (dhfr) locus. Tetradecanoylphorbol Acetate dihydrofolate reductase Cricetulus griseus
5 TPA incubation increased the expression and activity of DHFR. Tetradecanoylphorbol Acetate dihydrofolate reductase Cricetulus griseus
6 We conclude that one mechanism by which TPA enhances MTX resistance, mainly by gene amplification, is through an increase in Sp1 expression which leads to DHFR activation. Tetradecanoylphorbol Acetate dihydrofolate reductase Cricetulus griseus
