Role of Deoxyribonucleic Acid Origami for Alleviating Kidney and Liver Injury in Diabetic Sepsis

Abstract

Treating diabetic sepsis (DS) can be challenging because of the persistent infection of multiple organs. To address this complicated pathological condition, it is necessary to develop advanced materials and gain a better understanding of their roles. In this study, we developed a two-dimensional planar material with a rectangular deoxyribonucleic acid origami nanostructure (termed Rec-DON). Rec-DON was used to improve liver and renal function in DS mice, as it preferentially accumulates in these organs, and has superior anti-inflammatory activity and the ability to scavenge reactive oxygen species. The role of Rec-DON in the treatment of DS mice was investigated via quantitative proteomics. This study revealed that Rec-DON can regulate key proteins located primarily in the cytoplasm and mitochondrion, involved in protein transport, antigen processing and presentation, and steroid metabolic process, and can also bind to various proteins to restore liver and renal function in DS mice. This study presented Rec-DON as a liver and kidney targeting material and revealed its role in alleviating multiorgan injury in DS.
