Apoptosis and long non-coding RNAs: Focus on their roles in ischemic stroke.

Ischemic stroke (IS) is a severe and sudden cerebrovascular event, associated with notably high rates of mortality and morbidity. The process of apoptosis, a genetically orchestrated form of programmed cell death, is divided into two pathways: intrinsic and extrinsic. The intricate involvement of long non-coding RNA (lncRNA) in the pathobiology of IS, particularly in modulating neuronal apoptosis, is a burgeoning area of research. This review synthesizes the current understanding of the regulatory mechanisms of lncRNA on neuronal apoptosis in the context of ischemic stroke. Specifically, we highlight the roles of lncRNA such as ANRIL, C2dat1/2, H19, TUG1, MEG3, SNHG, and GAS5, which have been implicated in the facilitation of neuronal apoptosis. Conversely, the lncRNA N1LR has been shown to exert an inhibitory effect on this process. The role of MALAT1 in neuronal apoptosis remains a subject of ongoing debate, as its function oscillates between pro-apoptotic and anti-apoptotic roles, thus highlighting the need for further elucidation.
