Abstract
Autism Spectrum Disorder (ASD) is a neurodevelopmental disorder with increased prevalence and incidence in recent decades. Its etiology remains largely unclear, but it seems to involve a strong genetic component and environmental factors that, in turn, induce epigenetic changes during embryonic and postnatal brain development. In recent decades, clinical studies have shown that inutero exposure to valproic acid (VPA), a commonly prescribed antiepileptic drug, is an environmental factor associated with an increased risk of ASD. Subsequently, prenatal VPA exposure in rodents has been established as a reliable translational model to study the pathophysiology of ASD, which has helped demonstrate neurobiological changes in rodents, non-human primates, and brain organoids from human pluripotent stem cells. This evidence supports the notion that prenatal VPA exposure is a valid and current model to replicate an idiopathic ASD-like disorder in experimental animals. This review summarizes and describes the current features reported with this animal model of autism and the main neurobiological findings and correlates that help elucidate the pathophysiology of ASD. Finally, we discuss the general framework of the VPA model in comparison to other environmental and genetic ASD models.

Abstract
Excessive exposure to metals directly threatens human health, including neurodeve lopment. Autism spectrum disorder (ASD) is a neurodevelopmental disorder, leaving great harms to children themselves, their families, and even society. In view of this, it is critical to develop reliable biomarkers for ASD in early childhood. Here we used inductively coupled plasma mass spectrometry (ICP-MS) to identify the abnormalities in ASD-associated metal elements in children blood. Multi-collector inductively coupled plasma mass spectrometry (MC-ICP-MS) was applied to detect isotopic differences in copper (Cu) for further assessment on account of its core role in the brain. We also developed a machine learning classification method for unknown samples based on a support vector machine (SVM) algorithm. The results indicated significant differences in the blood metallome (chromium (Cr), manganese (Mn), cobalt (Co), magnesium (Mg), and arsenic (As)) between cases and controls, and a significantly lower Zn/Cu ratio was observed in the ASD cases. Interestingly, we found a strong association of serum copper isotopic composition (δ65Cu) with autistic serum. SVM was successfully applied to discriminate cases and controls based on the two-dimensional Cu signatures (Cu concentration and δ65Cu) with a high accuracy (94.4%). Overall, our findings revealed a new biomarker for potential early diagnosis and screening of ASD, and the significant alterations in the blood metallome also helped to understand the potential pathogenesis of ASD in terms of metallomics.

Abstract
Valproate (VPA), a widely-used antiepileptic drug, is a selective inhibitor of histone deacetylase (HDAC) that play important roles in epigenetic regulation. The patient with different diseases receiving this drug tend to exhibit weight gain and abnormal metabolic phenotypes, but the underlying mechanisms remain largely unknown. Here we show that VPA increases the Fto mRNA and protein expression in mouse hypothalamic GT1-7 cells. Interestingly, VPA promotes histone H3/H4 acetylation and the FTO expression which could be reversed by C646, an inhibitor for histone acetyltransferase. Furthermore, VPA weakens the FTO's binding and enhances the binding of transcription factor TAF1 to the Fto promoter, and C646 leads to reverse effect of the VPA, suggesting an involvement of the dynamic of histone H3/H4 acetylation in the regulation of FTO expression. In addition, the mice exhibit an increase in the food intake and body weight at the beginning of 2-week treatment with VPA. Simultaneously, in the hypothalamus of the VPA-treated mice, the FTO expression is upregulated and the H3/H4 acetylation is increased; further the FTO's binding to the Fto promoter is decreased and the TAF1's binding to the promoter is enhanced, suggesting that VPA promotes the assembly of the basal transcriptional machinery of the Fto gene. Finally, the inhibitor C646 could restore the effects of VPA on FTO expression, H3/H4 acetylation, body weight, and food intake; and loss of FTO could reverse the VPA-induced increase of body weight and food intake. Taken together, this study suggests an involvement of VPA in the epigenetic upregulation of hypothalamic FTO expression that is potentially associated with the VPA-induced weight gain.

Abstract
Autism spectrum disorder (ASD) is a complex neurodevelopmental disorder that begins in infancy. Although the etiology and pathogenesis are poorly understood, many studies have shown that ASD is closely related to structural and functional defects in the nervous system, especially synaptic transmission. The endocannabinoid (eCB) system is an important regulatory system of the central nervous system that regulates neurotransmission and synaptic plasticity and plays an important role in emotional and social responses and cognitive function. The relationship between eCB system and ASD has attracted increasing attention from scholars. In this review, we discuss the complex lipid signaling network of the eCB system, intracellular transport pathways, abnormal expression and association with various neurological diseases, and direct and indirect evidence for the link between eCB and ASD. Collectively, the findings to date indicate that the eCB system plays a key role in the pathophysiology of ASD and can provide new insights into potential interventions and rehabilitation strategies for ASD.

Abstract
BACKGROUD Autism spectrum disorders (ASD) are a complex group of neurodevelopmental disorders with a genetic basis. The role of long-chain polyunsaturated fatty acids (LC-PUFAs) and the occurrence of autism has been the focus of many recent studies. The present study investigates whether genetic variants of the fatty acid desaturase (FADS) 1/2 and elongation of very long-chain fatty acids protein (ELOVL) 2 genes, which are involved in LC-PUFA metabolism, are associated with ASD risk. METHODS A cohort of 243 ASD patients and 243 unrelated healthy controls were enrolled in this case control study. Sixteen tag single nucleotide polymorphisms from the FADS1-2 and ELOVL2 genes were genotyped using the Sequenom Mass Array. RESULTS There were significant differences in allelic distribution of FADS2 rs526126 (OR = 0.55, 95% CI = 0.42-0.72, pFDR < 0.05) between autistic children and controls. FADS2 rs526126 and ELOVL2 rs10498676 were associated with decreased ASD risk in recessive model (OR = 0.07, 95% CI = 0.02-0.22, pFDR < 0.01; OR = 0.56, 95% CI = 0.35-0.89, pFDR = 0.042), while ELOVL2 rs17606561, rs3756963, and rs9468304 were associated with increased ASD risk in overdominant model (OR = 1.63, 95% CI = 1.12-2.36, pFDR = 0.036; OR = 1.64, 95% CI = 1.14-2.37, pFDR = 0.039; OR = 1.75, 95% CI = 1.22-2.50, pFDR = 0.017). The A/A genotype of rs10498676 was correlated with a decline in the Autism Diagnostic Interview-Revised communication (verbal and nonverbal) domain. CONCLUSIONS These findings provide evidence of an association between FADS2 and ELOVL2 polymorphisms and ASD susceptibility in Chinese children.

Abstract
RATIONALE Autism spectrum disorders (ASD) are a set of pervasive neurodevelopmental disorders that manifest in early childhood, and it is growing up to be a major cause of disability in children. However, the etiology and treatment of ASD are not well understood. In our previous study, we found that serum levels of sphingosine 1-phosphate (S1P) were increased significantly in children with autism, indicating that S1P levels may be involved in ASD. OBJECTIVE The objective of this study was to identify a link between increased levels of S1P and neurobehavioral changes in autism. METHODS We utilized a valproic acid (VPA) -induced rat model of autism to evaluate the levels of S1P and the expression of sphingosine kinase (SphK), a key enzyme for S1P production, in serum and hippocampal tissue. Furthermore, we assessed cognitive functional changes and histopathological and neurochemical alterations in VPA-exposed rats after SphK blockade to explore the possible link between increased levels of S1P and neurobehavioral changes in autism. RESULTS We found that SphK2 and S1P are upregulated in hippocampal tissue from VPA-exposed rats, while pharmacological inhibition of SphK reduced S1P levels, attenuated spatial learning and memory impairments, increased the expression of phosphorylated CaMKII and CREB and autophagy-related proteins, inhibited cytochrome c release, decreased the expression of apoptosis related proteins, and protected against neuronal loss in the hippocampus. CONCLUSION We have demonstrated that an increased level of SphK2/S1P is involved in the spatial learning and memory impairments of autism, and this signaling pathway represents a novel therapeutic target and direction for future studies.

Abstract
AIMS To investigate the effect of FTY720 on the valproic acid (VPA) rat model of autism. MAIN METHODS As an animal model of autism, we used intraperitoneal injection of VPA on embryonic day 12.5 in Wistar rats. The pups were given FTY720 orally at doses of 0.25, 0.5 and 1mg/kg daily from postnatal day 15 to 35. Social behavior, spatial learning and memory were assessed at the end of FTY720 treatment. The histological change, oxidative stress, neuroinflammatory responses, and apoptosis-related proteins in the hippocampus were evaluated. KEY FINDINGS FTY720 (1mg/kg) administration to VPA-exposed rats (1) improved social behavior, spatial learning and memory impairment; (2) resulted in a reduction in neuronal loss and apoptosis of pyramidal cells in hippocampal CA1 regions; (3) inhibited activation of microglial cells, in turn lowering the level of pro-inflammatory cytokines interleukin-1β (IL-1β) and IL-6 in the hippocampus; (4) changed Malondialdehyde (MDA) levels, Glutathione (GSH) levels, superoxide dismutase (SOD) activity and Glutathione Peroxidase (GSH-Px) activity in the hippocampus; (6) inhibited the elevated Bax and caspase-3 protein levels and enhanced the relative expression level of Bcl-2 in the hippocampus; and (7) increased phospho-Ca2+/calmodulin-dependent protein kinase II (p-CaMKII), phospho-cAMP-response element binding protein (p-CREB) and Brain Derived Neurotrophic Factor (BDNF) protein expression in the hippocampus. SIGNIFICANCE FTY720 rescues social deficit, spatial learning and memory impairment in VPA-exposed rats. FTY720 exerts both a direct protection for neurons and an indirect modulation of inflammation-mediated neuron loss as a possible mechanism of neuroprotection.

Abstract
The primary aim of the present study was to investigate alterations in enzymes associated with fatty acid synthesis, namely fatty acid synthase (FASN) and acetyl-CoA carboxylase (ACC), in the prefrontal cortex and cerebellum of the valproic acid (VPA)-induced animal model of autism. In this model, pregnant rats were given a single intraperitoneal injection of VPA, and prefrontal cortex and cerebellum samples from their pups were analyzed. The results of western blotting and reverse transcription-quantitative polymerase chain reaction analyses demonstrated that the protein and mRNA expression levels of FASN, ACC and phospho-ACC (pACC) were increased in the prefrontal cortex and cerebellum of the VPA model of autism. Furthermore, in the prefrontal cortex and cerebellum of the VPA model of autism, AMPK expression is increased, whereas PI3K and Akt expression are unchanged. This suggests that disorder of the phosphatidylinositol-4,5-bisphosphate 3-kinase (PI3K)/Akt/FASN and/or adenosine 5'-monophosphate-activated protein kinase (AMPK)/ACC pathway may be involved in the pathogenesis of autism. It is hypothesized that fatty acid synthesis participates in autism through PI3K/Akt/FASN and AMPK/ACC pathways.
