Figure Lengend Snippet: Paroxetine (PRX) intervention improved the abnormal changes in the relative expression of α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid receptor (AMPAR)-related proteins and mRNA in rat hippocampus (HIP). (A) The interaction between modelling treatment × administration ( F (3,32) = 1.681, p = .1908) and modelling had no significant effect on glutamate receptor A1 (GluA1) protein expression in rats ( F (3,32) = 0.496, p = .6876), while administration had effect ( F (1,32) = 31.40, p < .0001). (B) The interaction of modelling treatment × administration ( F (3,32) = 6.769, p = .0012) and administration ( F (1,32) = 23.83, p < .0001) had a significant effect on the expression of GluA2 protein in rats, while modelling treatment ( F (3,32) = 2.225, p = .1043) had no significant effect. (C) The interaction of modelling treatment × administration ( F (3,32) = 1.129, p = .3522) and modelling ( F (3,32) = 1.749, p = .1767) had no significant effect on the expression of GluA3 protein in rats, but administration ( F (1,32) = 21.06, p < .0001) had a significant effect. (D) The interaction of modelling treatment × administration ( F (3,32) = 1.873, p = .1541) and modelling ( F (3,32) = 0.524, p = .6687) had no significant effect on the expression of mammalian target of rapamycin (mTOR) protein in rats, but administration ( F (1,32) = 23.73, p < .0001) had a significant effect. (E) The interaction of modelling treatment × administration ( F (3,32) = 2.938, p = .0481), modelling ( F (3,32) = 4.350, p = .0112), and administration ( F (1,32) = 38.08, p < .0001) had significant effects on the relative expression of GluA1 mRNA in rats. (F) The relative expression of GluA2 mRNA in rats was significantly affected by modelling × administration ( F (3,32) = 5.838, p = .0027), modelling ( F (3,32) = 21.58, p < .0001), and administration ( F (1,32) = 23.38, p < .0001). (G) Administration ( F (1,32) = 11.02, p = .0023) had a significant effect on the relative expression of GluA3 mRNA in rats, but modelling treatment × administration ( F (3,32) = 0.484 p = .6955) and modelling ( F (3,32) = 2.809, p = .0552) had no significant effect. (H) Administration ( F (1,32) = 35.36, p < .0001) had a significant effect on the relative expression of mTOR mRNA in rats, but modelling treatment × administration ( F (3,32) = 1.956, p = .1405) and modelling ( F (3,32) = 1.141, p = .3472) had no significant effect. CON = control; Sal = saline; SPS&S = single prolonged stress and shock; CUMS = chronic unpredictable mild stress; S + C = SPS&S + CUMS. Data are presented as mean ± SEM . Statistical comparisons were performed using two-way analysis of variance. * p < .05, ** p < .01, *** p < .001.
