Article Title: miR-129-3p Targeting of MCU Protects Against Glucose Fluctuation-Mediated Neuronal Damage via a Mitochondrial-Dependent Intrinsic Apoptotic Pathway
doi: 10.2147/DMSO.S285179
Figure Lengend Snippet: miR-129-3p overexpression alleviates oxidative stress in glucose fluctuation-exposed hippocampal neuronal cells by targeting MCU. Rat primary hippocampal neuronal cells were transfected with miR-NC, miR-129-3p mimics, miR-129-3p mimics+vector, or miR-129-3p mimics+MCU followed by glucose fluctuation treatment. ( A – C ) The concentration of mitochondrial Ca 2+ and O 2 − was detected using immunofluorescence. Scale bars = 50 μm. ( D ) GSH/GSSG ratio. ( E ) MnSOD activity. Data are presented as the means ± SD ; * p < 0.05, ** p < 0.01; (n = 5). CT, normal glucose; GV, glucose fluctuation; vector, MCU negative control (pcDNA3.1 vector).
