Fig. 8From: Activator Protein-1 Mediates Induced but not Basal Epidermal Growth Factor Receptor Gene ExpressionEGFR is increased in cis-platin resistant cells that have increased AP1 activity. Protein extracts from MCF-7, D551, KB, A2780 and A2780/CP70 cells were as described in “Materials and Methods.” 50 µg of each extract was fractionated on polyacrylamide gels and subjected to Western blot analysis using EGFR and actin antibodies.Back to article page
