Abstract
In the last years, lipid physiology has become an important research target for systems biology applied to the field of ecotoxicology. Lipids are not only essential components of biological membranes, but also participate in extra and intracellular signaling processes and as signal transducers and amplifiers of regulatory cascades. Particularly in sauropsids, lipids are the main source of energy for reproduction, growth, and embryonic development. In nature, organisms are exposed to different stressors, such as parasites, diseases and environmental contaminants, which interact with lipid signaling and metabolic pathways, disrupting lipid homeostasis. The system biology approach applied to ecotoxicological studies is crucial to evaluate metabolic regulation under environmental stress produced by xenobiotics. In this review, we cover information of molecular mechanisms that contribute to lipid metabolism homeostasis in sauropsids, specifically in crocodilian species. We focus on the role of lipid metabolism as a powerful source of energy and its importance during oocyte maturation, which has been increasingly recognized in many species, but information is still scarce in crocodiles. Finally, we highlight priorities for future research on the influence of environmental stressors on lipid metabolism, their potential effect on the reproductive system and thus on the offspring, and their implications on crocodilians conservation.

Abstract
In this study, we investigated the impact of Lactiplantibacillus plantarum (L. plantarum) CCFM8661 on the gut microbiota, and the serum and fecal metabolomes in lead (Pb)-exposed individuals. The volunteers recruited for this study were divided into two treatment groups, (i) the placebo (control) and (ii) the L. plantarum CCFM8661 treatment groups. The analysis revealed that probiotic intervention reversed some of the changes in Pb exposure-induced intestinal bacterial abundance, including the abundance of Parabacteroides, Bacteroides, Clostridiaceae, and Erysipelotrichaceae. An analysis of the fecal metabolome identified 26 differential metabolites involved in purine metabolism, unsaturated fatty acid metabolism, and other pathways. Serum metabolite analysis showed that L. plantarum CCFM8661 treatment altered the serum metabolite levels of various metabolic pathways, such as the glycerophospholipid, amino acid, and glutathione metabolism pathways. These results suggest that L. plantarum CCFM8661 may have beneficial effects on Pb-exposed populations by modulating the gut microbiota, host serum metabolism, and the metabolism of the gut microbiota.

Abstract
Introduction Lead is a ubiquitous environmental and industrial pollutant. Its nonbiodegradable toxicity induces a plethora of human diseases. A novel bioactive glycoprotein containing 1.15% carbohydrate, with the ability of adsorbing lead and effecting detoxification, has been purified from Auricularia polytricha and designated as APL. Besides, its mechanisms related to regulation of hepatic metabolic derangements at the proteome level were analyzed in this study. Methods Chromatographic techniques were utilized to purify APL in the current study. For investigating the protective effects of APL, Sprague-Dawley rats were given daily intraperitoneal injections of lead acetate for establishment of an animal model, and different dosages of APL were gastrically irrigated for study of protection from lead detoxification. Liver samples were prepared for proteomic analyses to explore the detoxification mechanisms. Results and discussion The detoxifying glycoprotein APL displayed unique molecular properties with molecular weight of 252-kDa, was isolated from fruiting bodies of the edible fungus A. polytricha. The serum concentrations of lead and the liver function biomarkers aspartate and alanine aminotransferases were significantly (p<0.05) improved after APL treatment, as well as following treatment with the positive control EDTA (300 mg/kg body weight). Likewise, results on lead residue showed that the clearance ratios of the liver and kidneys were respectively 44.5% and 18.1% at the dosage of APL 160 mg/kg, which was even better than the corresponding data for EDTA. Proteomics disclosed that 351 proteins were differentially expressed following lead exposure and the expression levels of 41 proteins enriched in pathways mainly involved in cell detoxification and immune regulation were normalized after treatment with APL-H. The results signify that APL ameliorates lead-induced hepatic injury by positive regulation of immune processing, and suggest that APL can be applied as a therapeutic intervention of lead poisoning in clinical practice. This report represents the first demonstration of the protective action of a novel mushroom protein on lead-elicited hepatic toxicity.

Abstract
Perfluorooctanoic acid (PFOA), a "forever chemical", is continuously discharged and mitigated in the environment despite its production and use being severely restricted globally. Due to the transformation, attachment, and adsorption of PFOA in aquatic environments, PFOA accumulates in the porous media of sediments, soils, and vadose regions. However, the impact of trace PFOA in the porous media on interstitial water and water safety is not clear. In this work, we simulated a porous media layer using a sand column and explored the effects of µg-level PFOA migration on microbial community alternation, microbial function regulation, and the generation and spread of microbial risks. After 60 days of PFOA stimulation, Proteobacteria became the dominant phylum with an abundance of 91.8%, since it carried 71% of the antibiotic resistance genes (ARGs). Meanwhile, the halogen-related Dechloromonas abundance increased from 0.4% to 10.6%. In addition, PFOA significantly stimulated protein (more than 1288%) and polysaccharides (more than 4417%) production by up-regulating amino acid metabolism (p< 0.001) and membrane transport (p < 0.001) to accelerate the microbial aggregation. More importantly, the rapidly forming biofilm immobilized and blocked PFOA. The more active antioxidant system repaired the damaged cell membrane by significantly up-regulating glycerophospholipid metabolism and peptidoglycan biosynthesis. It is worth noting that PFOA increased the abundance of antibiotic resistance genes (ARGs) and human bacterial pathogens (HBPs) in porous media by 30% and 106%. PFOA increased the proportion of vertical transmission ARGs (vARGs), and co-occurrence network analysis (r ≥ 0.8, p ≤ 0.01) verified that vARGs were mainly mediated by HBPs. A comprehensive understanding of PFOA interactions with its microecological environment is provided.

Abstract
The extensive use of the broad-spectrum antibiotics like oxytetracycline (OTC) has become a serious environmental issue globally. OTC has profound negative effects on aquatic organisms including fishes. In this study, RNA-Seq analysis was employed to examine the possible molecular mechanism of hepatotoxicology in zebrafish induced by OTC exposure. Adult male zebrafish was exposed to 0, 5, 90, and 450 μg/L OTC for 3 weeks. The results showed the decrease in body weight and tail length but the increase in total length of zebrafish under OTC exposure in a dose-dependent way. In addition, severe histopathological damages were featured by increasing tissue vacuolization in the livers of 450 μg/L OTC group. Moreover, RNA-Seq analysis revealed that molecular signaling and functional pathways in the liver were disrupted by OTC exposure. Furthermore, the down-regulation of gene expression after OTC exposure was found on both the genes related to fatty acid degradation and the genes related to lipid synthesis. The present study implied that OTC induced liver malfunction and fish health risks through growth retard, histopathological damages, molecular signaling disruption, genetic expression alteration, and lipid metabolism disturbance.

Abstract
Antibiotics are widely used around the world. Pollution of Sulfamethoxazole (SMX) in water poses a great threat to aquatic life. In this study, the toxic effects of SMX on the liver were assessed through RNA sequencing analysis and 16S rRNA sequencing analysis was conducted to determine the influence of SMX on gut microbiota of zebrafish (Danio rerio). Adult male zebrafish were exposed to 0, 5, 90 and 450 μg/L of environmentally relevant concentrations of SMX for 21 days respectively. The results showed that the liver had severe histopathological damages including pyknotic nuclei, cytoplasmic hyalinization and vacuolization and deformed hepatocytes with loose cell-to-cell contact. Transcriptomic analysis revealed that liver function was seriously affected by SMX exposure. Meanwhile, SMX exposure significantly inhibited the expression of genes associated with fatty acid synthesis, oxidation and transport. Besides, exfoliated and dissolved epithelial cells were observed in the gut after SMX treatment. Although there was no significant change on richness and species diversity of intestinal microbial community, the relative abundance of phylum and genus of SMX treatments were significantly different from that of control group. The present study implied that SMX may cause potential health risks to fish through inducing histopathological damages, genetic expression alterations, disorder of fatty acid metabolism and intestinal microbiota dysbiosis.

Abstract
Bursa of Fabricius (BF), one of primary lymphoid organ, is unique to birds. Meanwhile, lead (Pb) is well known for its high toxicology to birds. Therefore, this study aimed to examine the chronic toxic effects of lead exposure on BF in Japanese quails (C. japonica) and the underlying mechanism of lead immunotoxicity. One-week old male quails were exposed to 0 ppm, 50 ppm, 500 ppm and 1000 ppm Pb concentrations by drinking water for four weeks. The results showed that Pb accumulation in BF increased in a dose dependent way. The growth and development of BF was retarded in 500 ppm and 1000 ppm Pb groups. The number of lymphocytes was decreased and the release of immunoglobulin G and M (IgG, IgM), complement 3 and 4 (C3, C4) was inhibited by Pb exposure. Lead exposure also caused oxidative stress and increasing apoptosis in BF. Moreover, histopathological damages characterized by inflammatory hyperemia and inflammatory cell infiltration and ultrastructural injury featured by mitochondrial vacuole, cristae fracture and chromatin concentration were found in BF of 500 ppm and 1000 ppm Pb groups. Furthermore, RNA sequencing based transcriptomic analysis revealed that molecular signaling and functional pathways in BF were disrupted by lead exposure. In addition, the activation of Nuclear Factor kappa B (NF-κB) pathway while the inhibition of wingless integrated/catenin beta 1 (Wnt/β-catenin) signaling by Pb exposure were confirmed by quantitative real-time PCR (qPCR). Our study may benefit to understand potential mechanistic pathways of developmental immunotoxicology under Pb stress.
