In the present study, we observed that ART, DHA, and ARTS inhibited the expression level of Wnt5-a/b, down-regulated those of LRP6 and Dvl2, and subsequently reduced those of downstream genes mediated by β-catenin (i.e., nanog, sox2, oct3/4, and cyclin D1) in two lung cancer cell lines (Figure 4). This evidence concerns the gene NANOG and lung carcinoma.
