Over‐expression of miRNA‐9‐5p alleviated the destruction of blood–brain barrier after TBI. (a) The brain water content and (b) Evans blue permeability were detected to evaluate the brain edema at 3‐day post‐CCI (n = 5/group). (c) The immunoblotting and quantitative data of tight junction proteins (d) ZO‐1, (e) Occludin, and (f) Claudin‐5 acquired from traumatic foci at 3‐day post‐CCI (n = 5/group). (*** p < .001 vs. the Sham group; # p < .05, ## p < .01, ### p < .001 vs. the CCI group.) n: number of rats in each group; TBI: traumatic brain injury; CCI: control cortex impact
