FOS and breast cancer: Diversely, in BC samples of GSE15852, two pathways (“Focal adhesion” and “Retinol metabolism”) were positively correlated with the expression of FOS (Figure 10C; Table S9), while in BC samples obtained from GSE42568, 14 pathways were positively correlated with the expression of FOS, of which the top three were “Focal adhesion”, “Adherens junction”, and “Colorectal cancer” according to normalized enrichment score (Figure 10D–F; Table S9).
