Fig. 1From: Short-term early exposure to lapatinib confers lifelong protection from mammary tumor development in MMTV-erbB-2 transgenic miceLapatinib suppresses cell proliferation of 78617 and 85815 cells in vitro through RTK signaling inhibition. a An MTS assay of cell proliferation in 78617 and 85815 cells is shown after exposure for 4 days of indicated concentrations of lapatinib. Values are displayed as means ± standard error (S.E.). 78617 (b) and 85815 (c) cells were treated with lapatinib at indicated concentrations for 24 h. Expression and phosphorylation of specific markers were detected using Western blot analysisBack to article page
