ABSTRACT

The use of stem cells is a promising strategy for seizure treatment owing to their unique characteristics. We investigated the role of endothelial progenitor cells (EPCs) in a pentylenetetrazole (PTZ)-induced rat seizure model. A selected panel of long noncoding RNAs (lncRNAs), which maintain an elaborate balance in brain neural regulatory networks as well as the autophagy pathway, was also targeted. The impact of intravenously administered EPCs on PTZ-induced kindling in rats was evaluated by measuring the expression of neuronal damage markers, neurotrophic factors, and relevant lncRNA genes. Rat behavior was assessed using Y-maze test and open field test (OFT). EPCs mitigated seizure-associated neurological damage and reversed PTZ-induced working memory and locomotor activity deficits, as evidenced by improved performance in the Y-maze test and OFT. EPC treatment reversed the downregulation of the expression of the lncRNAs Evf2, Pnky, Dlx1, APF, HOTAIR, and FLJ11812. EPCs also boosted vascular endothelial growth factor (VEGF) expression. The ameliorative effect achieved by EPCs was comparable to that produced by valproate. These findings indicate that EPCs ameliorate kindling epileptic seizures and their associated abnormalities and that the effect of EPCs may be mediated via the upregulation of certain regulatory lncRNAs.
