ABCG2 and non-small cell lung carcinoma: Therefore, the present results showed that except for ABCG2, a transporter that is known to be responsible for the acquired resistance to gefitinib in NSCLC (Leggas et al., 2006; Usuda et al., 2007; Azzariti et al., 2010; Chen et al., 2011; Hegedüs et al., 2012; Zhu et al., 2015), ABCC10 was the only significant differential expressed transporter in both PC9/GR and H292/GR cells.
