We observed significantly greater mean GluR expression [F(5, 18) = 10.49 p < 0.001, Partial Eta Squared = 0.74] in PTSD groups that in the positive control (4.8 ± 1.14) (P < 0.01) and PTSD+saline (4.33 ± 0.79) (P < 0.05) groups compared to the negative control group (0.74 ± 0.16). This evidence concerns the gene GSR and post-traumatic stress disorder.
