PINK1 overexpression is protective for hippocampal neurons in epileptic rats. (A) Relative mRNA and protein levels of PINK1 in the hippocampus of epileptic rats detected by RT-qPCR and western blot analysis, n=3. (B-F) Representative images of H&E staining, Nissl staining, TUNEL assay, EJC staining and Hoechst 33258 nuclear staining, n=6. Data were analyzed by one-way ANOVA, and the pairwise comparisons following ANOVA were analyzed by Tukey's multiple comparisons test. **P<0.01, compared with the LV-NC group; ##P<0.01, compared with the antagomir-miR-142 + siRNA-NC group. miR-142, microRNA-142; PINK1, phosphatase and tensin homolog deleted on chromosome 10 (PTEN)-induced putative kinase 1; RT-qPCR, reverse transcription quantitative polymerase chain reaction; H&E, hematoxylin and eosin; ANOVA, analysis of variance; LV, lentivirus vector; NC, negative control.
