Abstract:
Sepsis is a life-threatening organ dysfunction caused by the host's dysregulated response to infection, with a complex pathogenesis and high mortality rate. Currently, there are no clear and effective treatment drugs available. Epigenetic modification serves as a major mechanism regulating gene expression under pathological and physiological conditions, and it has been shown to play a critical role in regulating the occurrence and development of sepsis. Histone acetylation modification, as a sophisticated epigenetic modification mechanism, plays a crucial regulatory role in many aspects of life. It can jointly regulate the acetylation status of histones through histone acetyltransferase (HAT) and histone deacetylase (HDAC), thereby changing DNA expression and dynamically regulating sepsis related gene expression at the epigenetic level. Previous studies have shown that histone acetylation can participate in the progression of sepsis by regulating inflammatory mediators, nuclear factor-ΚB (NF-ΚB) signaling pathway, autophagy, efferocytosis, ferroptosis, pyroptosis. These mechanisms are promising targets for novel sepsis treatments. In addition, with the deepening of research, it has been found that various selective/non selective histone deacetylase inhibitors (HDACI) can regulate histone acetylation status by acting on different HDAC targets, which has been shown to alleviate organ damage caused by sepsis and improve prognosis in septic animal models. This article further summarizes the role and potential applications of histone acetylation in sepsis, providing new ideas for the treatment of sepsis.
