Abstract
In the present study, we aimed to illustrate the roles and working mechanisms of long non-coding RNA (lncRNA) rhabdomyosarcoma 2-associated transcript (Rmst) and EGb761 in oxygen-glucose deprivation (OGD)-induced brain microvascular endothelial cells (BMECs). OGD exposure augmented the level of Rmst while reduced the expression of miR-150 in bEnd.3 cells. MiR-150 could directly bind to Rmst in bEnd.3 cells. Rmst silencing abrogated the inhibitory influences on the proliferation and migration and the promoting impact on the apoptosis of bEnd.3 cells caused by OGD exposure. Rmst overexpression intensified OGD-induced injury in bEnd.3 cells. OGD induced the injury of bEnd.3 cells through Rmst/miR-150 axis. EGb761 attenuated the damage in bEnd.3 cells induced by OGD through targeting Rmst/miR-150 axis. EGb761 might be an effective therapeutic agent to protect brain microvascular endothelial cells from hypoxia-ischemia induced injury.
