MEG3 and ischemic stroke: Recent research has pointed out that the alteration of lncRNA‐MEG3 level may be associated with aggravation or alleviation of middle cerebral artery occlusion (MCAO) or oxygen–glucose deprivation/reoxygenation (OGD/R)‐induced neuronal ischemic injury, indicating that lncRNA‐MEG3 could be a notable biomarker for ischemic stroke and is remarkably involved in neuronal death, particularly during CIRI [8, 9, 10].
