Finally, among the upregulated DEGs, we observed in the GR cells a strong induction of several cancer stem cell (CSC) markers previously identified in NSCLC [9]: a cluster of differentiation antigens such as CD117 and CD133, cell membrane transporters such as ABCB1 and ABCG2, Frizzled family receptor (FZD) members, and ALDH1 isoforms (Figure 4). The gene discussed is ABCB1; the disease is cancer.
