ARK5 expression levels and gefitinib sensitivity in NSCLC cells. (A) mRNA and (B) protein expression (western blot) of ARK5 in the three NSCLC cell lines (GAPDH was used as a loading control). ARK5 expression was highest in the NCL-H1299 cell line. (C) Viability of NSCLC cells detected under different concentrations of gefitinib using the CCK-8 assay. (D) The IC50 value was calculated based on the CCK-8 results.
