Fatty acid metabolism-related proteins were significantly increased in ovarian cancers relative to controls (fold change > 1.5), including ACAA1 (fold change = 2.70, p = 1.00E − 2), ACOX1 (fold change = 1.53, p = 3.40E − 2), CPT2 (fold change = 2.05, p = 1.99E − 2), ECHS1 (fold change = 1.52, p = 3.56E − 3), ECI1 (fold change = 1.64, p = 1.99E − 3), and PECR (fold change = 1.57, p = 4.14E − 4). Here, ECI1 is linked to ovarian cancer.
