Other novel FTSEC biomarkers that are overexpressed in HGSOCs include CELSR3, an atypical cadherin; ABCC3, an ABC transport protein implicated in drug resistance [34]; and CTHRC1, a secreted protein shown to be a candidate biomarker for breast and pancreatic cancer [35,36]. Here, ABCC3 is linked to familial pancreatic carcinoma.
