Upregulation of miR-874-3p decreases cerebral ischemia/reperfusion injury by directly targeting BMF and BCL2L13.

In this study, we found that miR-874-3p levels significantly decreased in rat I/R brain induced by middle cerebral artery occlusion/reperfusion (MCAO/R) and SH-SY5Y cells following oxygen-glucose deprivation and reperfusion (OGD/R) treatment. Upregulation of miR-874-3p reduced infarct volumes and cell apoptosis in the in vivo I/R stroke model using TTC and TUNEL staining, as well as increased proliferation and inhibited apoptosis in OGD/R induced SH-SY5Y cells by CCK-8, Edu staining and flow cytometry analysis. Mechanistically, bioinformatics analysis and luciferase reporter assay confirmed BCL-2-modifying factor (BMF) and Bcl-2 family protein Bcl-rambo (BCL2L13) were the direct targets of miR-874-3p. Furthermore, BMF or BCL2L13 knockdown also provided significant protection against OGD/R induced injury, while their overexpression reversed the protective effects of miR-874-3p on SH-SY5Y cells following OGD/R. In summary, our results suggest that miR-874-3p attenuated ischemic injury by negatively regulating BMF and BCL2L13, highlighting a novel therapeutic target for ischemic stroke.
