The multifaceted role of Sestrin 3 (SESN3) in oxidative stress, inflammation and tumorigenesis

Abstract

The pathogenesis of inflammation and tumors is a focal point of scientific inquiry, with oxidative stress often serving as the primary initiator. Within the human genome, the SESN3 gene encodes the SESN3 protein, a crucial antioxidant stress protein. Acting as a regulatory factor, SESN3 intricately modulates cellular oxidative stress, actively participating in cellular protection and repair mechanisms. Its functions span antioxidative, anti-aging, and anti-tumor properties. The expression of SESN3 is closely linked to cellular and oxidative stress, metabolic status, and specific signaling pathways. This review aims to delve into the origins and functions of SESN3, its role within signaling pathways, and its contributions to inflammation and tumorigenesis.
