(A) pERK expression in various Kras mutant lung cancer cell lines after
trametinib treatment by western blot.
(B) Viability of lung tumor cell lines after selumetinib treatment.
Samples were biological replicates.
(C) Survival of HKP1 lung-cancer-bearing mice after 3 weeks selumetinib
treatment.
(D) pERK expression in CD4+ and CD8+ T cells from HKP1 tumor-bearing
lungs after selumetinib or trametinib treatment by flow cytometry.
Samples were biological replicates. *p < 0.05; **p < 0.01;
***p < 0.001; and ****p < 0.0001, Welch’s t test. NS, not
significant. Error bars represent SD. The experiments were performed 2–3
times, and representative results are shown here.
