Popis: Objective To explore the interaction between microRNA-23 (miR-23) and mitochondrial fission protein 1 (FIS1) in human kidney-2 (HK-2) cells and examine the effect of miR-23 on inflammatory response and oxidative stress by targeting FIS1. Methods HK-2 cells were cultured in vitro and induced by lipopolysaccharide (LPS) for modeling of sepsis. Dual luciferase reporter assay was utilized for verifying the interaction between miR-23 and FIS1. HK-2 cells were randomized into groups of miR-23 mimic/inhibitor and eukaryotic expression vector and small interfering RNA of FIS1 alone or in a combination. Cell proliferation was detected by cell counting kit-8 (CCK-8) assay and apoptosis and reactive oxygen species (ROS) were examined by flow cytometry. Malondialdehyde (MDA) was detected by MDA kit and the levels of tumor necrosis factor t (TNF-α), interleukin (IL)-1β and IL-6/10 were measured by enzyme-linked immunosorbent assay(ELISA). ResultsThe miR-23 mRNA in HK-2 cells induced by LPS was (0.60±0.12) folds that of control group(P
