LncRNA MALAT1 Promotes OGD-Induced Apoptosis of Brain Microvascular Endothelial Cells by Sponging miR-126 to Repress PI3K/Akt Signaling Pathway.
Ischemic stroke (IS) is a common disease that seriously endangers human health. Patients with IS present with increased death of brain microvascular endothelial cells (BMECs). MALAT1 is found to be upregulated in IS patients. ⋯ Overexpression of miR-126 activated the PI3K/Akt pathway, which in turn affected the proliferation and apoptosis of HBMECs. MALAT1 negatively regulated PI3K/Akt pathway. MALAT1 inhibited the proliferation and induced the apoptosis of OGD-induced HBMECs through suppressing PI3K/AKT pathway by sponging miR-126, providing a potential therapeutic target for IS.
