PON1 and hepatocellular carcinoma: In addition, enhanced fucosylation of serum paraoxonase 1 (PON1) (58), α-1-antitrypsin (A1AT) (43), hemopexin (Hpx) (55), complement C3 (C3), ceruloplasmin (CE), histidine-rich glycoprotein (HRG), CD14 (65) and fibrinogen (51) have been reported to be potential glycobiomarkers for early-stage HCC detection.
