3.1.3.1 Serum N-glycan profile has potential as a biomarker of
aging
It has been previously reported that the serum N-glycan profile of
Belgians and Italians has changed during aging, and its potential as a
biomarker for aging has been proposed[54]. The 12 most significant
N-glycan structures were analyzed by exoglycosidase digestion[55].
Finally, it was found that the relative abundance of the three main
N-glycan structures (NGA2F, NGA2FB and NA2F) changed significantly with
age, and had the same variation trend in both sexes, which made the
serum N-glycan profile have the potential as a biomarker of aging.
