Results showed downregulation of ALDH1A1 and ALDH3A1 in H1792 cells and Aldh1a1 in MDA-F471 cells, which are known to be overexpressed in KRAS-mutant LUAD CSCs, the downregulation of CCL20 in H1792 and MDA-F471, which plays a major role in the growth and metastasis of lung cancer cells, and the downregulation of Alcam and Tnf in MDA-F471, epithelial cell marker and proinflammatory cytokine, respectively [48]. The gene discussed is KRAS; the disease is lung cancer.
