线粒体是一种动态的细胞器,不断进行分裂和融合。裂变和聚变之间的平衡决定了细胞的命运。在这项研究中,我们表明,线粒体分裂因子(MFF)上调过氧化氢处理或缺血/再灌注(I/R)损伤。敲低MFF可减轻过氧化氢和I/R损伤诱导的心肌细胞凋亡和心肌梗死。我们发现MFF是miR-761的直接靶点,miR-761通过抑制MFF抑制线粒体分裂和心肌细胞凋亡。这项研究揭示了一种新的线粒体裂变调控模型,该模型由miR-761和MFF组成。调节它们的水平可能为解决细胞凋亡和心肌梗死提供新的途径。
Mitochondria are dynamic organelles that constantly undergo fission and fusion. The balance between fission and fusion determines the fate of the cell. In this study, we show that mitochondrial fission factor (MFF) is upregulated upon hydrogen peroxide treatment or ischemia/reperfusion (I/R) injury. Knockdown of MFF attenuated hydrogen peroxide- and I/R injury-induced cardiomyocyte apoptosis and myocardial infarction. We found that MFF is a direct target of miR-761, and miR-761 inhibits mitochondrial fission and cardiomyocyte apoptosis by repressing MFF. This study reveals a novel model of mitochondrial fission regulation, which is composed of miR-761 and MFF. Modulation of their levels may provide a new approach for tackling apoptosis and myocardial infarction.
