(a–f) In vivo studies showing how silencing of miR-134 protects against status epilepticus. Graphs and representative photomicrographs from the dorsal hippocampus of mice 24 h after status epilepticus in mice treated beforehand with Scr (as control) or Ant-134. Shown are the counts for three markers, Fluoro-Jade B (FJB, a marker of neuronal death; a,b), DNA fragmentation (terminal deoxynucleotidyl dUTP nick end labeling; TUNEL; c,d) and the neuronal marker NeuN (c,d). Mice injected with Ant-134 show a clear reduction in FJB and TUNEL staining and less of a loss of NeuN staining after status epilepticus, highlighting the neuroprotective effects of the antagomir.
