Updated project metadata. High blood glucose level is one of the main characteristics of diabetes mellitus (DM). It is speculated that longevity families may have certain advantages in blood glucose regulation. But till now, limited information on these items is reported. In this study, a TMT- based comparative quantitative proteomics analysis was used to reveal the changes of plasma proteomics profiles between longevity subjects and non-longevity area participants in order to identify plasma proteins associated with glucose metabolism in longevity population and to explore the characteristics of blood glucose regulation in longevity population
