Paper

Abstract

Senescence is observed in various tissues during different physiological and pathological events such as tissue remodeling and disorders related aging. Senescent cells suffer from a decline in methionine sulfoxide reductase (MsrA), which is intimately linked to cell proliferation and longevity. Monitoring MsrA may contribute to senescence research in larval development and age-related disorders. However, only a limited number of MsrA fluorescent probes have been reported, and none of them have been applied to respond to MsrA specifically and recognize senescent cells. This project developed a novel fluorescent probe

Research summary

The paper claims to develop a novel fluorescent probe for monitoring methionine sulfoxide reductase (MsrA) in senescent cells. This research is relevant as it addresses the decline of MsrA linked to cellular senescence, which is a fundamental aspect of aging and longevity.
