ATP5MK and cancer: On the other hand, comprehensive analyses of AGP glycans in plasma from various cancer patients by using the MALDI-TOF-MS system indicated that the relative abundance of fucosylated glycans in AGP was significantly elevated in cancer patients unexceptionally and that such fucosylated glycans predominantly consisted of tri- and tetra-antennary glycan chains with mono- and difucosylated glycans (Figure 1) along with the occurrence of drastic changes in the glycan structures of the AGP molecule [22,23].
