Figure 2. MiR-484 increased viability and inhibited apoptosis of neurons following oxygen-glucose deprivation (OGD). (a) CCK8 assay was applied to determine cell viability for each group, including OGD treated group, OGD treated + miR-484 inhibitor group, OGD treated + NC inhibitor group, OGD treated + miR-484 mimics group, and OGD treated + NC mimics group.

Figure 3. MiR-484 directly regulated BCL2L13 expression by binding to the 3ʹ-UTR of BCL2L13. (a) Forecast of miR-484 binding sites on target gene BCL2L13 by TargetScan. (b) Dual-luciferase assays were carried out after cells were co-transfected BCL2L13-WT or BCL2L13-MUT with miR-484 inhibitor, NC inhibitor (control), miR-484 mimics, and NC mimics (control), respectively. (c) The protein expression levels of BCL2L13 in cells were determined by western blot. β-actin was applied as the endogenous reference genes.
