Research progress on SIRT1 and sepsis.

SIRT1, a member of the sirtuin family, belongs to the NAD⁺-dependent class III histone deacetylase. SIRT1 can regulate gene expression by catalyzing non-histone and histone lysine residues deacetylation. SIRT1 also plays important roles in glucose and lipid metabolism, cell aging, tumorigenesis and inflammation. Recent studies indicate that SIRT1 can inhibit the inflammatory responses via regulating several inflammatory signaling pathways. It is closely related to the occurrence and development of sepsis and other inflammatory diseases. Research has been done on relevant signaling pathways of SIRT1 as well as its target genes during inflammation. SIRT1 is a hot spot in uncontrolled inflammatory response research. This article focuses on the role of SIRT1 in inflammation, especially its targets and involved signaling pathways in sepsis, and tries to provide more convincing evidence for the clinical treatment of sepsis and other inflammatory diseases.
