BDNF and epilepsy: The mRNA and protein expression of BDNF in the hippocampus tissues of rats increased significantly in the EP + miR-103a inhibitors group in comparison to the EP + inhibitors NC group (P < 0.05; Fig. 6), indicating that the inhibition of miR-103a could promote the expression of BDNF in the hippocampus tissues of epilepsy rats, and preliminarily suggested that miR-103a was associated with BDNF.
