In contrast to the small gene set (IGF2BP1, SRF, FOXK1 and PDLIM7), the enlarged gene set (35 genes plus IGF2BP1 and SRF) was significantly associated with poor OS probability in serous ovarian cancer, HCC as well as LUAD, as supported by HR values ranging from 1.52 to 2.15 (Figure 6G and Supplementary Figure S7B). This evidence concerns the gene FOXK1 and ovarian serous adenocarcinoma.
