To investigate transcriptional factors upstream of the main differentially expressed genes in ccRCC, we generated a transcriptional factor network and observed that several core transcriptional factors were associated with the differentially expressed genes namely, FLI1, ETS1, SREBF2, PML, CEBPB, RUNX1, MYBL2, CENPA, FOXM1, and LMNB1 (Figure 4(d)). The gene discussed is FOXM1; the disease is nonpapillary renal cell carcinoma.
