Antagonizing increased miR-135a levels at the chronic stage of experimental TLE reduces spontaneous recurrent seizures

Increased miR-135a levels are observed in human patients with temporal lobe Epilepsy (TLE) and in experimental animal models. Upon targeting the increased miR-135a levels in vivo using antagomirs in kainic acid induced status epilepticus mouse model of TLE, we observed a strong reduction of spontaneous recurrent seizures. To understand this further and to find target mRNAs that potentially mediate the seizure suppressive function of miR-135a, we performed immunoprecipitation using biotin tagged miRNA mimics, followed by RNAsequencing (RNAseq). We found several novel neuronal targets of miRNA-135a and identified Mef2a as a key target in this study. Here we report the total RNAseq data. Overall design: N2A cells were transfected with biotin tagged miRNA mimics for miR-135a and negative control and immunoprecipitations were performed. N = 3 replicates of IP and input samples for each condition were generated and sequenced on illumina platform for total RNA for identification of novel targets of miR-135a.
