| Description | Mesial temporal lobe epilepsy (mTLE) is a chronic neurological disorder characterized by recurrent seizures. Accumulating evidence of microRNAs´ (miRNAs) potential involvement in pathogenic mechanisms underlying mTLE is emerging. The function of microRNAs in chronic mTLE is still poorly understood partially due to the lack of a clear cut miRNA expression profile of epileptic foci. In the present study, we performed the whole miRNome profiling analysis of the human brain tissue employing novel approach combining next generation sequencing (NGS) with an advanced qPCR technique, miQPCR. miRNA profiles of the hippocampus of autopsy controls and mTLE patients were compared, and analysis revealed differential miRNA expression of 24 miRNAs consistent with published data as well as several miRNA species never considered to play a role in epilepsy before. In conclusion, NGS exposed a group of miRNAs manifesting invariable expression across all samples out of which stable expression of four miRNAs was validated by combined methods for future utilization as negative controls or normalizers. |
