ProtFI, an efficient frailty-trained proteomics-based biomarker of aging, robustly predicts age-related decline
Cell Rep Methods. 2026 Apr 10:101405. doi: 10.1016/j.crmeth.2026.101405. Online ahead of print.ABSTRACTMany molecular aging biomarkers have been developed to capture heterogeneity in individual aging rates. Yet, systematic comparison of the modeling choices underlying these biomarkers has been limit
