Besides, MHC molecules, including HLA-B (cor = 0.365, p = 5.69e-11), HLA-DMA (cor = 0.413, p = 7.02e-14), HLA-DPA1 (cor = 0.475, p = 2.03e-18), HLA-DQA1 (cor = 0.467, p = 8.07e-18), and HLA-E (cor = 0.447, p = 2.6e-16), were significantly correlated with the expression of SUCNR1 in ovarian cancer (Figures 5A,E). Here, HLA-DQA1 is linked to ovarian cancer.
