Figure 9From: A phosphorylation defective retinoic acid receptor mutant mimics the effects of retinoic acid on EGFR mediated AP-1 expression and cancer cell proliferationEGFR expression and ERK1 activation are inhibited in S77A RARα mutant cells. Cells were harvested for western blot as described above. Blots were incubated with anti-human primary antibodies to EGFR, activated ERK1 (anti-pERK1), and total ERK1. These experiments were performed three times using different lysates with similar results. Representative blots are shown.Back to article page
