Figure 8From: ERK1 and ERK2 mitogen-activated protein kinases affect Ras-dependent cell signaling differentiallyERK2 activation is significantly reduced in tumors overexpressing ERK1. (a) Two individual tumors for each clone were explanted from treated mice and subjected to western blot analysis to determine ERK2 activation and transgene expression. (b) Mean ± SEM of the data in (a) are plotted as indicated.Back to article page
