ARNT and ovarian serous carcinoma: Combining all the methods mentioned above, we found that only four DEGs (SRC, ARNT, TBP, and SNAI2) showed stronger and closer relationships than the other biomarkers in each functional protein–protein interaction network (Figure 3A–C) and had consistent synchronous poor effects on PFS and OS among patients with serous ovarian carcinomas with statistical significance (Figure 3D–K).
