Effect of OXT on expression level of Pex14 and PMP70 in the different brain regions of 3-NP injected male rats. 3-NP reduced Pex14 (b, e, h and k) and PMP70 (c, f, i and l) protein levels in the studied brain regions in comparison with the Control group while OXT improved this effects in all studied brain areas of male rats. Data are presented as means ± SEM. (n = 6/group). *p < 0.05, **p < 0.01, ***p < 0.001, ****p < 0.0001 compared with the Control; ##p < 0.01, ###p < 0.001 compared between the 3-NP and 3-NP-OXT groups. OXT: oxytocin; 3-NP: 3-Nitropropionic acid; Pex14: peroxin 14; PMP70: peroxisomal membrane protein of 70 kDa
