Research Abstract |
The purpose of this study is to clarify the candidates of the biomarker of successful aging through glycomics and glycoproteomics of semisuper centenarians considered as a model of human longevity. I performed sugar chains analyses, lectin microarray analyses, and glycopeptides analyses, and compared the glycosylation of plasma proteins between semisuper centenarians and controls. As a result, multi-branched complex sugar chains and high sialylated sugar chains were increased in the plasma proteins of semisuper centenarians. Sialylated glycopeptides of inflammatory mediating proteins were decreased with aging, while not in semisuper centenarians. It was suggested that the glycosylation plays an important role in successful aging of semisuper centenarians.
