Next, we examined the expression of MDR markers, specifically ABCB1, ABCC1, and ABCG2, in NSCLC cultures after treatment with afatinib, alectinib, ceritinib, crizotinib, dabrafenib, erlotinib, gefitinib, nintedanib, osimertinib, and trametinib. Here, ABCB1 is linked to non-small cell lung carcinoma.
