Dynamic regulation effect of long non-coding RNA-UCA1 on NF-kB in hippocampus of epilepsy rats

We aimed to discuss the mechanism of occurrence and progression of epilepsy through analyzing the expression changes of UCA1 and NF-Kb in temporal hippocampus and UCA1 in peripheral blood in rats with epilepsy induced by lithium chloride-pilocarpine.

The lithium chloride-pilocarpine-induced epilepsy rat model was established; 1, 7, 14, 30, and 60 d after status epilepticus were selected as the time points of research. The expression levels of UCA1 and NF-kB in the hippocampus of rats and UCA1 in peripheral blood were detected and analyzed using quantitative Real-time PCR (qRT-PCR). The differences and correlations between expression levels of UCA1 and NF-kB at each time point of research in experimental group and control group were analyzed statistically.

Results showed that mRNA expression levels of UCA1 and NF-kB in brain tissues in experimental group were higher than those in control group at each time point. The change trend of expression levels of UCA1 and NF-kB with time was consistent. The expression level of UCA1 in peripheral blood in experimental group at each time point was higher than that in control group, and mRNA expression level of UCA1 in peripheral blood in experimental group was positively correlated with that in brain tissue.

The expressions of UCA1 and NF-Kb are in the dynamic change in the formation of epilepsy, suggesting that UCA1 may participate in the pathogenesis of epilepsy, so as to provide a potentially feasible new direction for guiding the clinical diagnosis and treatment of epilepsy.
