Mitochondria are central to the execution of apoptosis, and the Bcl-2 protein family of pro- and anti-apoptotic proteins interacts with mitochondria to regulate apoptosis. Using bioinformatics we predicted that miR-181, a microRNA expressed in brain, could target the 3′UTRs of Bcl-2 family members Bcl-2-L11/Bim, Mcl-1, and Bcl-2. Using the luciferase reporter assay we confirmed these targets. We used mimic and inhibitor to alter miR-181a levels in primary astrocyte cultures and found miR-181a reduction was associated with increased Bcl-2 and Mcl-1 protein levels. Decreased miR-181a levels reduced glucose deprivation induced apoptosis, mitochondrial dysfunction, and loss of mitochondrial membrane potential in astrocytes.
