Recent studies have shown that AAT, NFkB, PMVK and some other proteins are significantly higher in high grade serous ovarian carcinoma than in normal tissue, which can be used as biomarkers for predicting good prognosis [24].Correspondingly, such as PD-1, PD-L1, VAP1, FABP4, and PF4 are associated with poor prognosis [25]; . Here, SERPINA1 is linked to ovarian serous carcinoma.
