Increased core fucosylation of ELHHLQEQ762NVSNAFLDK of ceruloplasmin (A) and ML354NTSSLLEQLNEQFNWVSR of clusterin (B) significant at the stage of liver cirrhosis. Representative LC-MRM-MS traces of the transition (920.1/1179.6; [M+3H]3+) of ML354N(HexNAcFuc)TSSLLEQLNEQFNWVSR (C) and the transition (871.4/1179.6; [M+3H]3+) of ML354N(HexNAc)TSSLLEQLNEQFNWVSR (D) of clusterin (s, significant at p < 0.05; ns, non-significant; Ctrl, control; FIB, fibrosis; CIR, cirrhosis).
