"Comparative evaluation of different chemical agents induced Autism Spectrum Disorder in experimental Wistar rats". Behav Brain Res 2024; 458:114728. [PMID: 37923221 DOI: 10.1016/j.bbr.2023.114728] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/30/2023] [Revised: 10/04/2023] [Accepted: 10/18/2023] [Indexed: 11/07/2023]
Abstract
Autism Spectrum Disorder (ASD) is a complex neurodevelopmental condition with uncertain etiology and pathophysiology. Several studies revealed that the commonly used animal models like Valproic Acid (VPA) and Propionic Acid (PPA) do not precisely represent the disease as the human patient does. The current study was conducted on different chemically (VPA, PPA, Poly I:C, Dioxin (2,3,7,8-Tetrachlorodibenzo-p-dioxin (TCDD)) & Chlorpyrifos (CPF)) induced ASD-like animal models and validated the best suitable experimental animal model, which would closely resemble with clinical features of the ASD. This validated model might help to explore the pathophysiology of ASD. This study included rat pups prenatally exposed to VPA, PPA, Poly I:C, Dioxin & CPF within GD9 to GD15 doses. The model groups were validated through developmental and behavioral parameters, Gene Expressions, Oxidative Stress, and Pro-inflammatory and Anti-inflammatory cytokines levels. Developmental and neurobehavioral parameters showed significant changes in model groups compared to the control. In oxidative stress parameters and neuro-inflammatory cytokines levels, model groups exhibited high oxidative stress and neuro-inflammation compared to control groups. Gene expression profile of ASD-related genes showed significant downregulation in model groups compared to the control group. Moreover, the Poly I:C group showed more significant results than other model groups. The comparison of available ASD-like experimental animal models showed that the Poly I:C induced model represented the exact pathophysiology of ASD as the human patient does. Poly I:C was reported in the maternal immune system activation via the inflammatory cytokines pathway, altering embryonic development and causing ASD in neonates.

Abstract
Titanium nanoparticles and pyrethroid pesticides are now being widely used in industrial, agriculture, and biomedical applications. In recent years, their health safety profiles have aroused concerns among health scientists. This study mainly explored the combined effects of titanium dioxide nanoparticles (TiO2NPs) and cypermethrin (CYP) on reproductive toxicity in male rats by gavage for 90 days. Thirty-two male Sprague-Dawley rats were assigned to four groups: the control group, the TiO2NPs group, the CYP group, and the combined titanium dioxide nanoparticles with cypermethrin (TiO2NPs + CYP) group. The results of biochemical analysis on testicular tissue homogenate showed that TiO2NPs and CYP mixtures decreased the activities of glutathione peroxidase (GSH-Px) and catalase (CAT) while increasing the activity of malondialdehyde (MDA) and lactate dehydrogenase (LDH). Meanwhile, the results of two-way factorial analysis of variance (ANOVA) showed a significant effect on GSH-Px, CAT, LDH, testicular cell apoptosis, and sperm quality in rats after exposure. Furthermore, the combined exposure group exhibited apoptosis of testicular cells and DNA damage. The results indicated that exposure to a mixture of TiO2NPs and CYP had adverse effects on the reproductive status of male rats.
