Figure 3From: Antitumor and antiangiogenic effect of the dual EGFR and HER-2 tyrosine kinase inhibitor lapatinib in a lung cancer model Analysis of cell survival after 2 μM lapatinib treatment. A. A549 cells exposed to 2 μM lapatinib for 24 h exhibited a reduced cell growth proliferation (P < 0.001); B. After 10 days of exposure to lapatinib, the number of colonies was dramatically abrogated (***: P < 0.0001).Back to article page
