Fatty acid degradation-related proteins were significantly increased in ovarian cancers relative to controls (fold change > 1.5), including CPT2 (fold change = 2.05, p = 1.99E − 2), ACOX1 (fold change = 1.53, p =3.40E-2), EHHADH (fold change = 1.62, p = 2.25E − 3), ECHS1 (fold change = 1.52, p = 3.56E − 3), and ECI1 (fold change = 1.64, p = 1.99E − 3). Here, ECHS1 is linked to ovarian cancer.
