Advances in Multiomic Analyses of Frailty Biomarkers in the Elderly

Abstract

Early diagnosis of frailty is of great value in helping the elderly to regain their health, as it is a non-specific state of reduced physiological reserve, resistance to disease and ability to recover from stress caused by the impairment in homeostasis maintained by multiple systems with sarcopenia as the basic characteristic. Recent developments in multiomic techniques provide new approaches to the detection of potentially specific, stable and reliable biomarkers of pre-frailty. We collected and reviewed recent advances in multiomic techniques for identifying frailty biomarkers, involving genomics, transcriptomics, proteomics and metabolomics, which can assist in assessing the risk of frailty, exploring potential mechanisms of frailty and developing targeted interventions to support healthy aging.
