To confirm the results obtained from the CL cells, we examined the KIF14 expression levels in other lung adenocarcinoma cell lines (Figure S2B) and overexpressed KIF14 in A549 cells with low endogenous KIF14 protein and silenced KIF14 in H1299 cells with relative high KIF14 protein levels. The gene discussed is KIF14; the disease is lung adenocarcinoma.
