To further analyze the expression of prognosis-related genes in ovarian cancer, we compared the expression levels of the 12 identified prognostic genes (BANF1, CDK2AP2, DDT, EPS8, LRIG1, MRPL4, NUCB2, PAF1, PMP22, RABGAP1L, S100A13, and USO1) across different sample types. Here, DDT is linked to ovarian cancer.
