TMT-labeled quantitative protein profiling of hippocampus during human aging

ABSTRACT: Human hippocampus is one of the critical brain regions affected by aging. However, a fully understanding of aging-related changes in protein profiles in human hippocampus has not been well described, especially for the Chinese population. With the newly founded human brain bank in Chinese Academy of Medical Sciences & Peking Union Medical College, we performed a 4-plex TMT labeled proteomic study in the hippocampus of postmortem human brains. The ages of death ranged from 22-98, and were grouped into 4 aging groups: 20-50, 50-70, 70-90, and over 90 (n=4 each). None of the donors was diagnosed with neurodegenerative diseases according to their medical history. Our data identified 4582 proteins, among which 99 proteins were upregulated and 42 proteins were downregulated during the aging process.
