MCF-7 cells are treated with or without 5 μg/mL cisplatin (DDP) for 48 h after preincubated with or without Lapatinib at the indicated concentrations for 6 h, respectively. Then the levels of ER-α36, total EGFR and P-EGFR, total HER-2 and P-HER-2, total ERK and P-ERK are evaluated using western blot.

MDA-MB-231 cells are serum-starved overnight and pre-treated with 3 μM Lapatinib or DMSO for 3 hours. After that time, cells are lysed (0hr) or stimulated with EGF for 1, 8, 24, 48, and 72 hours. Western blots of p-EGFR (Tyr1173), EGFR, p-cJun (ser63), cJun, and vinculin are shown with band densitometries beneath.

The combined use of MEK162 with HER kinase inhibitor Lapatinib, almost completely abolishes MAPK signaling as evidenced by diminished phospho-Erk levels. Western blot analyses of ERK signaling in tumor transplants from mice treated as indicated. Three hours after their dose on day four of treatment, the mice are sacrificed for analysis. Vinculin is used as a loading control.
