That these results are generalizable to other cell lines and to primary human cancers was suggested by the GSEA analyses showing a positive correlation between AHR or CYP1B1 and FN, VCAM1, THBS2, COL14A1, COL15A1, MMP1, and MMP13 and a negative correlation with CDH1 (Figure 4). This evidence concerns the gene COL15A1 and cancer.
