DNA Methylation of miR-122 Aggravates Oxidative Stress in Colitis Targeting SELENBP1 Partially by p65NF-κB Signaling
Figure 3
miR-122 was downregulated in the oxidative stress model of human intestinal epithelial cell line HT-29. (a) CCK-8 analysis of cell viability after treatment of H2O2 with different concentrations. (b–d) The protein levels of MDA, SOD, and ROS in the supernatant of culture medium under different concentrations of H2O2 were examined by ELISA. (e, f) The relative levels of miR-122 and SBP1 mRNA in HT-29 cells were detected by qRT-PCR under different concentrations of H2O2. (g) Western blotting analysis of SBP1 expression in HT-29 cells with different concentrations of H2O2. (h) The prediction of the binding between miR-122 and SBP1 by TargetScan. The dual-luciferase reporter assay was performed to verify the interaction of miR-122 and SBP1. , , and vs. 0 μM.
