This research aimed to investigate the regulatory mechanisms underlying miR-155-5p in sepsis-induced AKI. CLP-treated mice were used as an in vivo model of sepsis-induced AKI, and LPS-treated HK-2 and TCMK-1 cells were used as in vitro models. Bioinformatics analyses and mechanistic assays were utilized to reveal the relationships between molecules. H&E staining was used to reveal morphological changes in kidney tissues. ELISAs were conducted to detect the concentrations of proinflammatory cytokines. We discovered that miR-155-5p was prominently upregulated in sepsis-induced AKI in vivo and in vitro. MiR-155-5p inhibition alleviated kidney injury in mice.
