Itamar Harel is an Israeli scientist and faculty member in the Department of Genetics at the Alexander Silberman Institute of Life Sciences, the Hebrew University of Jerusalem, Israel. His research focuses on vertebrate aging and age-related diseases.
Research
Harel is a geneticist known for his work on aging and related diseases, as reviewed in[1][2][3][4]. Harel's research focuses on understanding the mechanisms of aging and longevity, with a particular interest in using the emerging African turquoise killifish (Nothobranchius furzeri) model to study these processes.[5][6][7][8] His work aims to uncover the biological pathways that influence aging in order to develop potential interventions to promote healthy aging.
Harel developed a genetic platform in the naturally short-lived turquoise killifish[9][10], which lives only twice as long as Drosophila. Using this vertebrate model he explored protein aggregation with age, revealing naturally occurring prion-like behaviors that propose an alternative mechanism for damage propagation during aging.[11][12]
He then explored how aging is scaled between species, what mediates its sexual dimorphism, and why longevity is proportional to other species-specific traits such as age at maturity. In a series of studies, the Harel lab revealed additional mechanisms that regulate vertebrate longevity. They identified how reproduction might impact vertebrate aging by demonstrating that the germline itself can regulate longevity and stress resistance in a sex-specific manner.[7][13] Additionally, the Harel lab discovered another vertebrate longevity mechanism linked to energy homeostasis via the AMP-activated protein kinase (AMPK) pathway.[8][14]
Research in Harel's laboratory also focuses on developing genetic tools, including lineage tracing, modeling of sporadic age-related cancers, and precise control of pituitary hormones in vivo.[15][16][17]
