| Popis | Purpose: The primary aim of this study was to identify specific miRNAs with aberrant expression in hippocampal tissue of mesial temporal lobe epilepsy (mTLE) patients with hippocampal sclerosis (HS). Method: We analyzed miRNA isolated from paraffin embedded tissue slices of hippocampal complex from 22 mTLE +HS patients (14 left-sided, 8 right-sided) and 9 post mortem controls. To characterize the miRNAs highly prone to be involved in the pathological changes in the mTLE+HS brain tissue we performed the expression analysis combining the next generation sequencing (NGS) and novel specific technique for miRNA quantification miQPCR. Results: By both methodical approaches we confirmed significant upregulation of miR-129-1-3p, 129-2-3p, 142-3p, 191-5p, 193b-3p, 195-5p, 374b-5p, 451a, and 490-3p in mTLE+HS patients. The levels of miRNA-184 were significantly higher in control subjects. Differential expression levels in mTLE+ HS patients were identified also in the case of 10 miRNA species never considered to play a role in epilepsy before. Conclusion: Analytical approach combining NGS with miQPCR used for the first time for analysis of human epileptic foci led to reliable identification of miRNA with altered expression in mTLE +HS patients. |
