For this test, we co-cultured 1) MRC-5, a fetal primary human lung fibroblast [34], and 2) A549-luc-c8, adenocarcinoma human alveolar basal epithelial cells transduced to express luciferase [35], under different concentrations of LAN-A for 12 h (Figure 3A, top). This evidence concerns the gene CDCA3 and adenocarcinoma.
