Advances in Circular RNA in the Pathogenesis of Epilepsy.

[Display omitted] • First critical review focusing on the role of circRNA in pathogenesis of epilepsy. • Pathogenesis of epilepsy is closely related to circRNA. • circRNA has the potential to serve as a biomarker for epilepsy. Recent studies evidenced the involvement of circular RNA (circRNA) in neuroinflammation, apoptosis, and synaptic remodeling suggesting an important role for circRNA in the occurrence and development of epilepsy. This review provides an overview of circRNAs considered to be playing regulatory roles in the process of epilepsy and to be involved in multiple biological epilepsy-related processes, such as hippocampal sclerosis, inflammatory response, cell apoptosis, synaptic remodeling, and cell proliferation and differentiation. This review covers the current research status of differential expression of circRNA-mediated seizures, m6A methylation, demethylation-mediated seizures in post transcriptional circRNA modification, as well as the mechanisms of m5C- and m7G-modified circRNA. In summary, this article reviews the research progress on the relationship between circRNA in non-coding RNA and epilepsy. [ABSTRACT FROM AUTHOR]
