Abstract
Bisphenol A (BPA) is a well-documented endocrine-disrupting chemical widely used in plastic products. In addition to its endocrine-disrupting effects, BPA exhibits immunotoxicity. Many countries have banned BPA because of its adverse effects on human health. In recent years, many chemicals such as bisphenol B (BPB), bisphenol E (BPE), bisphenol S (BPS), and bisphenol fluorene (BHPF) have been used to replace BPA. Because these replacement chemicals have chemical structures similar to that of BPA, they may also harm human health. However, their immunotoxicity and the molecular mechanisms underlying their toxicity remain largely unknown. The aim of this study was to investigate the immunotoxicity of BPA and its replacement chemicals, as well as the underlying mechanisms by exposing primary human lymphocytes to BPA and its replacement chemicals. Our results showed that exposure to BPA and its replacement chemicals altered the interleukin (IL) and cytokine production, such as IL-1b, IL-5, IL-6, IL-8, interferon alfa-2b (IFN-a2B), and tumor necrosis factor alpha (TNF-α), in the lymphocytes. Among these, BPA and BHPF caused a greater inhibition. Using comparative transcriptomic analysis, we further investigated the biological processes and signaling pathways altered by BHPF exposure. Our data highlighted alterations in the immune response, T cell function, and cytokine-cytokine receptor interactions in human lymphocytes through the deregulation of gene clusters. In addition, the results of ingenuity pathway analysis demonstrated the inhibition of T lymphocyte function, including differentiation, movement, and infiltration. Our results, for the first time, delineate the mechanisms underlying the immunotoxicity of BHPF in human lymphocytes.

[PMID: 38579451 DOI: 10.1016/j.envint.2024.108620] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/15/2024] [Revised: 03/21/2024] [Accepted: 03/31/2024] [Indexed: 04/07/2024]
Abstract
Per- and polyfluoroalkyl substances (PFAS), ubiquitous environmental contaminants, pose significant challenges to ecosystems and human health. While cell cultures have emerged as new approach methodologies (NAMs) in ecotoxicity research, metabolomics is an emerging technique used to characterize the small-molecule metabolites present in cells and to understand their role in various biological processes. Integration of metabolomics with cell cultures, known as cell culture metabolomics, provides a novel and robust tool to unravel the complex molecular responses induced by PFAS exposure. In vitro testing also reduces reliance on animal testing, aligning with ethical and regulatory imperatives. The current review summarizes key findings from recent studies utilizing cell culture metabolomics to investigate PFAS toxicity, highlighting alterations in metabolic pathways, biomarker identification, and the potential linkages between metabolic perturbations. Additionally, the paper discusses different types of cell cultures and metabolomics methods used for studies of environmental contaminants and particularly PFAS. Future perspectives on the combination of metabolomics with other advanced technologies, such as single-cell metabolomics (SCM), imaging mass spectrometry (IMS), extracellular flux analysis (EFA), and multi-omics are also explored, which offers a holistic understanding of environmental contaminants. The synthesis of current knowledge and identification of research gaps provide a foundation for future investigations that aim to elucidate the complexities of PFAS-induced cellular responses and contribute to the development of effective strategies for mitigating their adverse effects on human health.

Abstract
Perfluorooctanoic acid (PFOA) is a member of Per- and polyfluoroalkyl substances (PFASs), an industrial pollutant that has been produced for decades and widely used in various industries. Accumulation of this compound in the environment and body of organisms led to increased concerns about this compound. The toxic effects of PFOA on the nervous system are unknown yet. We aimed to assess the myelination and neurogenesis in brain tissue. In this study, PFOA at doses of 1, 5, 10, and 20 mg/kg were injected intraperitoneally into C57BL/6 J mice for 14 days, and the myelin content, CD4 + and CD8 + cell infiltration to brain regions were evaluated. Also, bromodeoxyuridine (BrdU) labeling was performed to compare neurogenesis among the groups. Luxol Fast Blue (LFB) staining revealed a significant decrease in myelin content in both sex at high concentrations (p < 0.001). The BrdU incorporation changes were observed in both sexes especially females which was highly related to the dose of PFOA and region of the brain. The infiltration rates of CD4 + and CD8 + cells to the brain were shown to be decreased; meanwhile the lymphocyte count was not significantly changed among groups over time and vice versa for the monocyte and neutrophils. Our results showed that PFOA had a negative impact on neurogenesis and the myelination process through the specific region of the brain depending on the dose and sex. Also, PFOA could disturb the number of CD4 + and CD8 + cells infiltrating the brain, which plays a crucial role in neurogenesis, leading to toxicity and neurological abnormalities. It seems that more research is needed to determine the exact mechanisms of PFOA neurotoxicity and its long-term behavioral consequences.

Abstract
Perfluorooctanoic acid (PFOA) is widely used in aviation science and technology, transportation, electronics, kitchenware, and other household products. It is stable in the environment and has potential nephrotoxicity. To investigate the effect of PFOA exposure during pregnancy on the kidneys of offspring mice, a total of 20 mice at day 0 of gestation were randomly divided into two groups (10 mice in each group), and each group was administered 0.2 mL of PFOA at a dose of 3.5 mg/kg or deionized water by gavage during gestation. The kidney weight, kidney index, histopathological observation, serum biochemistry, transcriptomics, and metabolomics of the kidneys of the 35-day offspring mice were analyzed. In addition, malondialdehyde (MDA), superoxide dismutase (SOD), and catalase (CAT) levels in the kidney were measured. Transcriptome analysis results showed that 387 genes were up-regulated and 283 genes were down-regulated compared with the control group. These differentially expressed genes (DEGs) were mainly concentrated in the peroxisome-proliferator-activated receptor (PPAR) signaling pathway and circadian rhythm. Compared with the control group, 64 and 73 metabolites were up- and down-regulated, respectively, in the PFOA group. The altered metabolites were mainly enriched in the biosynthesis of unsaturated fatty acids. PFOA can affect the expression levels of circadian rhythm-related genes in the kidneys of offspring mice, and this change is influenced by the PPAR signaling pathway. PFOA causes oxidative stress in the kidneys, which is responsible for significant changes in metabolites associated with the biosynthesis of unsaturated fatty acids.

Abstract
Perfluorooctanoic acid (PFOA) represents an increasing public health concern due to its persistence in the environment and its toxic effects. The gut microbiota is known to produce various metabolites that assist the host to maintain metabolic homeostasis. However, few studies have explored the effects of PFOA on gut-microbiota-related metabolites. In the present study, male C57BL/6J mice were exposed to 1 ppm of PFOA in drinking water for four weeks and integrative analysis of the gut microbiome and metabolome was performed to reveal the health effects of PFOA. Our results showed that PFOA disturbed both the gut microbiota composition and the metabolic profiles of the feces, serum, and liver in mice. A correlation was found between Lachnospiraceae UCG004, Turicibacter, Ruminococcaceae, and different fecal metabolites. Significant alterations of gut-microbiota-related metabolites were induced by PFOA exposure, including bile acids and tryptophan metabolites such as 3-indoleacrylic acid and 3-indoleacetic acid. The findings of this study are helpful to improve the understanding of the health effects of PFOA, which might be mediated through the gut microbiota and its related metabolites.

Abstract
Several per- and polyfluoroalkyl substances (PFAS) have been linked to metabolic disorders in organisms. However, few studies have considered their combined effects, which would be more representative of PFAS occurring in the environment. In this study, zebrafish embryos were exposed to a mixture of 18 PFAS at three environmentally relevant concentrations for 5 days to assess their bioconcentration and metabolic consequences. The burdens of ∑PFAS in zebrafish larvae were 0.12, 1.58, and 9.63 mg/kg in the 0.5, 5, and 50 μg/L treatment groups, respectively. Exposure to the PFAS mixture accelerated hatching and larval heart rates, increased energy expenditure, and reduced ATP levels and glucose contents due to decreased feed intake and glucose uptake. Metabolomic analysis revealed that exposure to the PFAS mixture enhanced glycolysis but inhibited phospholipid synthesis, and significantly increased the expression of lipid metabolism related genes (srebf1, acox, and pparα), which indicated enhanced β-oxidation. The significant changes in mitochondrial membrane potential, mitochondrial content, and the transcription of genes involved in the mitochondrial respiratory chain (mfn2, ndufs1, atp5fa1, and mt-nd1) and mitochondrial DNA replication and transcription (18rs-rrn, and polg1) suggested that exposure to the PFAS mixture could cause mitochondrial dysfunction and further disrupt glucose and lipid metabolic pathways, ultimately causing metabolic disorders in zebrafish larvae. These findings demonstrate the importance of assessing the metabolic effects of PFAS mixtures on early development in wildlife and humans.

Abstract
Perfluorooctanoic acid (PFOA) is widely used in industrial and consumer products of our daily life. It is well-documented that PFOA is closely associated with fatty liver disease. Recently, cumulating studies demonstrated the immunotoxicity of PFOA, but its harmful effect on the largest immune organ, spleen is still largely unknown. In the present study, we used PFOA-exposed mouse model together with comparative transcriptomic analysis to understand the molecular mechanisms underlying the immunotoxicity of PFOA. Furthermore, we investigated the possible use of vitamin C to reverse the PFOA-induced immunotoxicity in spleen. Our result showed that the PFOA exposure could reduce the spleen weight and plasma lymphocytes, and the splenic comparative transcriptomic analysis highlighted the alteration of cell proliferation, metabolism and immune response through the regulation of gene clusters including nicotinamide nucleotide transhydrogenases (NNT) and lymphocyte antigen 6 family member D and K (LY6D and LY6K). More importantly, the supplementation of vitamin C would relieve the PFOA-reduced spleen index and white blood cells. The bioinformatic analysis of transcriptome suggested its involvement in the spleen cell proliferation and immune response. For the first time, our study delineated the molecular mechanisms underlying the PFOA-induced immunotoxicity in the spleen. Furthermore, our results suggested that the supplementation of vitamin C had beneficial effect on the PFOA-altered spleen functions.

Abstract
Ovarian cancer is a gynecological malignancy characterized with increasing death rate in the world. It is clinically reported that chemotherapy against ovarian cancer is still found with poor curative effect and potential side effect. Plumbagin is an emerging anti-cancer compound. Although some experimental findings of plumbagin anti-ovarian cancer activity are described, the pharmacological targets should be further explored. In this study, we aimed to investigate the underlying pharmacological activities and targets of plumbagin against ovarian cancer in vitro. As results, in silico docking analysis suggested plumbagin potently treating ovarian cancer through regulating pharmacological targets, including octamer-binding transcription factor 4 (OCT4) and Kruppel-like factor 4 (KLF4). The preliminary experimental data showed that plumbagin treatment inhibited cell growth and induced apoptosis in cancer cells. In addition, decreased mRNA expressions of intracellular OCT4, PCNA, and elevated KLF4 mRNA activation were detected in plumbagin-treated cancer cells. Furthermore, immunostaining determination showed reduced OCT4-positive cells and increased KLF4-positive cells were observed following plumbagin treatments. To sum up, our current findings have preliminarily showed the anti-ovarian cancer benefits of plumbagin, and the pharmacological targets may be identified as KLF4 and OCT4 pathway. Thus, we conclude that plumbagin may be a bioactive compound for ovarian cancer treatment.

Abstract
Tetrabromobisphenol A (TBBPA) is extensively utilized as a brominated flame retardant in numerous chemical products. As an environmental contaminant, the potential human toxicity of TBBPA has been attracting increasing attention. Nonetheless, the exact underlying mechanisms of toxicological effects caused by TBBPA remain uncertain. In this study, we investigated the potential mechanisms of TBBPA toxicity in vitro in the A549 cell line, one of the widely used type II pulmonary epithelial cell models in toxicology research. Cell viability was determined after treatment with varying concentrations of TBBPA. Liquid chromatography-mass spectrometry (LC-MS) metabolomics and metabolic flux approaches were utilized to evaluate metabolite and tricarboxylic acid (TCA) cycle oxidative flux changes. Our findings demonstrated that TBBPA significantly reduced the viability of cells and attenuated mitochondrial respiration in A549 cells. Additionally, LC-MS data showed significant reductions in TCA cycle metabolites including citrate, malate, fumarate, and alpha-ketoglutarate in 50 μM TBBPA-treated A549 cells. Metabolic flux analysis indicated reduced oxidative capacity in mitochondrial metabolism following TBBPA exposure. Moreover, diverse metabolic pathways, particularly alanine, aspartate, and glutamate metabolism and the TCA cycle, were found to be dysregulated. In total, 12 metabolites were significantly changed (p < .05) in response to 50 μM TBBPA exposure. Our results provide potential biomarkers of TBBPA toxicity in A549 cells and help elucidate the molecular mechanisms of pulmonary toxicity induced by TBBPA exposure.

Abstract
The exposome reflects multiple exposures across the life-course that can affect health. Metabolomics can reveal the underlying molecular basis linking exposures to health conditions. Here, we explore the concept and general data analysis framework of "molecular gatekeepers"─key metabolites that link single or multiple exposure biomarkers with correlated clusters of endogenous metabolites─to inform health-relevant biological targets. We performed untargeted metabolomics on plasma from 152 adolescent girls participating in the Growing Up Healthy Study in New York City. We then performed network analysis to link metabolites to exposure biomarkers including five trace elements (Cd, Mn, Pb, Se, and Hg) and five perfluorinated chemicals (PFCs; n-PFOS, Sm-PFOS, n-PFOA, PFHxS, and PFNA). We found 144 molecular gatekeepers and annotated 22 of them. Lysophosphatidylcholine (16:0) and taurodeoxycholate were correlated with both n-PFOA and n-PFOS, suggesting a shared dysregulation from multiple xenobiotic exposures. Sphingomyelin (d18:2/14:0) was significantly associated with age at menarche; yet, no direct association was detected between any exposure biomarkers and age at menarche. Thus, molecular gatekeepers can also discover molecular linkages between exposure biomarkers and health outcomes that may otherwise be obscured by complex interactions in direct measurements.

Zhang R, Lu W, Yao Y, Tu L, Yu T, Luan T, Chen B. Metabolomics analysis of the 3D L-02 cell cultures revealing the key role of metabolism of amino acids in ameliorating hepatotoxicity of perfluorooctanoic acid. THE SCIENCE OF THE TOTAL ENVIRONMENT 2022; 806:150438. [PMID: 34562763 DOI: 10.1016/j.scitotenv.2021.150438] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/16/2021] [Revised: 09/14/2021] [Accepted: 09/15/2021] [Indexed: 06/13/2023]
Abstract
To simulate the real cell status and morphology in the living systems is substantial for using cell models to address the detrimental effects of toxic contaminants. In this study, the comparative profiles of metabolites in three-dimensional (3D) human normal liver (L-02) cell spheroids with perfluorooctanoic acid (PFOA) treatment were analyzed using a metabolomic approach. The uniform 3D cell spheroids were well formed in 3 days (e.g., sphericity index >0.9) and stably maintained over the subsequent 11 days. The cytotoxicity of PFOA to the 3D L-02 cell spheroids was highly dependent on both exposure concentration and duration. Comparative analysis of metabolomes showed that the number of differential metabolites in the 3D cell spheroids treated with 300 μM PFOA for 10 days (n = 59) was greater than those with a 4-day exposure to 300 μM PFOA (n = 17). Six metabolic pathways related to amino acids metabolism were only found in the 3D cell spheroids with a 10-day treatment of 300 μM PFOA, which could not be found in the 2D monolayer cells and those 3D cell spheroids with a 4-day exposure. The suppression of PFOA on glutamine metabolism substantially decreased glutathione (GSH) production and accordingly increased the level of reactive oxygen species in the 3D cell spheroids. On the contrary, the supplementation of glutamine increased GSH production and the viability of cell spheroids, indicating that glutamine metabolism played a critical role in the chronic toxic effects of PFOA. Our study strongly suggested that comprehensive toxicological methodologies based on the 3D cell models could currently be robust and suitable for addressing the chronic adverse effects of toxic contaminants.

Abstract
Introduction Perfluorooctanoic acid (PFOA) is a compound used as an industrial surfactant in chemical processes worldwide. Population and cross-sectional studies have demonstrated positive correlations between PFOA levels and human health problems. Objectives Many studies have focused on the hepatotoxicity and liver problems caused by PFOA, with little attention to remediation of these problems. As an antioxidant, vitamin C is frequently utilized as a supplement for hepatic detoxification. Methods In this study, we use a mouse model to study the possible role of vitamin C in reducing PFOA-induced liver damage. Based on comparative transcriptomic and metabolomic analysis, we elucidate the mechanisms underlying the protective effect of vitamin C. Results Our results show that vitamin C supplementation reduces signs of PFOA-induced liver damage including total cholesterol and triglyceride levels increase, liver damage markers aspartate, transaminase, and alanine aminotransferase elevation, and liver enlargement. Further, we show that the protective role of vitamin C is associated with signaling networks control, suppressing linoleic acid metabolism, reducing thiodiglycolic acid, and elevating glutathione in the liver. Conclusion The findings in this study demonstrate, for the first time, the utility of vitamin C for preventing PFOA-induced hepatotoxicity.

CHEMOSPHERE 2022; 287:132160. [PMID: 34509005 DOI: 10.1016/j.chemosphere.2021.132160] [Citation(s) in RCA: 7] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/29/2021] [Revised: 08/31/2021] [Accepted: 09/02/2021] [Indexed: 06/13/2023]
Abstract
Ulcerative colitis (UC) is an inflammatory bowel disease (IBD) that causes long-term inflammation and ulcers in the colon and rectum. Approximately 3 million adults were diagnosed with IBD in the US in 2015, and its incidence rate is estimated to increase by 4-6 times in 2030. Industrial pollutants are largely responsible for this significant increase in UC cases. Several epidemiological and animal studies have demonstrated the correlation between pollutants and gastrointestinal diseases, but detailed molecular mechanisms responsible for adverse effects of environmental pollutants on UC are still unknown. In the present study, we used a dextran sulfate sodium (DSS)-induced colitis mouse model, comparative metabolomics analysis, and systematic bioinformatics analysis to delineate the synergistic adverse effects of bisphenol A (BPA) and its substitute fluorene-9-bisphenol (BHPF) on UC. Subsequently, a significant alteration in gut metabolites was observed by the BPA and BHPF treatments. Furthermore, the bioinformatics analysis indicated deregulation of sugar and fatty acid metabolisms in the DSS-induced colitis model by the BPA and BHPF treatments, respectively. Additionally, both the treatments induced an inflammatory response in the model. Particularly, some DSS-deregulated metabolites, which play important roles in gut inflammation, were synergistically induced or reduced by the BPA and BHPF treatments. To the best knowledge of the authors, the synergistic adverse effects of the BPA and BHPF treatments on UC were demonstrated for the first time through gut metabolism alterations. Therefore, the present study provides novel insights in the role of environmental pollutants, such as BPA and BHPF, in UC development.

Abstract
This bioinformatics study aimed to characterize and certify crucial anti-cancer targets, functional processes, and molecular mechanisms of Pachyman in treating hepatocellular carcinoma (HCC) by using pharmacology network and molecular docking analyses, by experimental validation. The crucial anti-HCC targets of Pachyman, including ALB, VEGFA, TNF, CASP3, SRC, EGF, CXCR4, STAT3, HRAS, HSP90AA1, MMP9, BCL2L1, FGF2, and PTPRC, were identified. In addition, the correlative networks of all crucial biotargets of Pachyman in treating HCC were created accordingly. Functionally, these crucial genes were correlated using angiogenesis and neoplastic metastasis of HCC. Interestingly, the molecular docking findings indicated that ALB and VEGFA in HCC might be potent pharmacological targets of Pachyman. In experimental validation, the clinical samples of HCC showed reduced ALB protein expression and increased VEGFA protein level. Following Pachyman treatments in vitro, the intracellular level of ALB protein was elevated, whereas the cellular content of VEGFA protein was downregulated. Taken together, current bioinformatics findings based on pharmacology network and molecular docking analyses elucidate the detailed molecular targets and signaling mechanisms of Pachyman in treating HCC. Interestingly, validated biotargets of ALB and VEGFA may be main potential biomarkers for detecting HCC medically.

Abstract
Ulcerative colitis (UC) is a complex inflammatory bowel disorder that can induce colonic and rectal dysfunction. Mesalazine, a first-line medicine, is routinely prescribed for UC treatment. However, the pharmacological targets of mesalazine against UC are not detailed in current publications. In the current study, a transcriptomics strategy was applied to reveal the therapeutic targets and molecular mechanisms of mesalazine for treating dextran sulfate sodium (DSS)-induced UC in mice. Compared with the UC group, a total of 1,663 differentially expressed genes were identified in mesalazine-treated mice, of which 262 were upregulated and 1,401 were downregulated. GO and KEGG enrichment analyses indicated that the protective actions of mesalazine for treating UC were related to the functional regulation of immune inflammatory response, such as the regulation of T cells, white blood cells, and cytokine receptor pathways. In addition, ingenuity pathway analysis of the gene network further revealed the inhibitory action of mesalazine on C-C motif chemokine ligands (CCL11 and CCL21) and C-X-C motif chemokine ligands (CXCL3 and CXCR2). Taken together, the current transcriptomic findings revealed anti-UC pharmacological targets, including the newly discovered biotargets CCL11, CCL21, CXCL3, and CXCR2, of mesalazine against DSS-induced intestinal inflammation.

Abstract
Pachymic acid (PA), a bioactive ingredient isolated from Poria cocos Wolf, is reported with potential benefits of anti-inflammatory, anti-oxidative actions. It is reasoned that PA may play the potential benefits against cystitis glandularis (CG), an inflammation of the bladder tissue. In this study, we aimed to apply the network pharmacology and molecular docking analyses to reveal concrete anti-CG targets and mechanisms of PA, and then the bioinformatic findings were verified by using clinical and animal samples. The methodological data from network pharmacology approach showed that 303 and 243 reporting targets of CG and PA, and other 31 shared targets of CG and PA were identified. Subsequently, all top targets of PA against CG were screened out, including cyclooxygenase-2, epidermal growth factor receptor, tumor antigen p53 (TP53), tumor necrosis factor-alpha (TNF), interleukin-1 (IL-1) beta, proto-oncogene c-jun. Molecular docking data demonstrated that PA exerted potent bonding capacities with TNF, TP53 proteins in CG. In human study, the findings suggested that overactivated TNF-α expression and suppressed TP53 activation were detected in CG samples. In animal study, PA-treated mice showed reduced intravesical IL-1, IL-6 levels, and lactate dehydrogenase content, downregulated TNF-α and upregulated TP53 proteins in bladder samples. Taken together, our bioinformatics and experimental findings identify the key anti-CG biotargets and mechanisms of PA. More markedly, these pivotal pharmacological targets of PA against CG have been screened out and verified by using computational and experimental analyses.

Abstract
Recent evidences have suggested that genistein, a beneficial isoflavonoid, exerts marked anti-proliferative action on colorectal cancer (CRC) cells. However, the exact molecular mechanisms behind anti-CRC effect of genistein have not been elucidated. In current report, a systemic pharmacology analysis was used to disclose the anti-CRC mechanism of genistein prior to performing experimentative certification. As shown in network pharmacology findings, a total of 189 common targets and 9 hard-core targets of genistein-anti-CRC were collected and identified. And the detailed anti-CRC functions and pathways mediated by genistein were uncovered. In further certification, human CRC samples resulted in elevated protein and mRNA expressions of myeloid leukemia cell differentiation protein (MCL1), beta amyloid A4 protein (APP), and vascular endothelial growth factor receptor 2 (KDR). In animal experiment, genistein-treated tumor-transplanted nude mice exhibited reduced tumor growth, accompanied with dose-dependent down-regulations of MCL1, APP, and KDR proteins and mRNAs. Taken together, the integrated bioinformatic and experimental findings uncover the anti-CRC mechanisms and targets mediated by genistein. Significantly, parts of hard-core biotargets were experimentally verified before clinical application, including MCL1, APP, and KDR.

Abstract
Prenatal exposure to widespread environmental toxicants is detrimental to maternal health and fetal development. The effects of environmental toxicants on maternal and fetal metabolic profile changes have not yet been summarized. This systematic review aims to summarize the current studies exploring the association between prenatal exposure to environmental toxicants and metabolic profile alterations in mother and fetus. We searched the MEDLINE (PubMed) electronic database for relevant literature conducted up to September 18, 2019 with some key terms. From the initial 155 articles, 15 articles met the inclusion and exclusion criteria, and consist of highly heterogeneous research methods. Seven studies assessed the effects of multiple environmental pollutants (metals, organic pollutants, nicotine, air pollutants) on the maternal urine and blood metabolomic profile; five studies evaluated the effects of arsenic, polychlorinated biphenyls (PCBs), nicotine, and ambient fine particulate matter (PM2.5) on the cord blood metabolomic profile; and one study assessed the effects of smoking exposure on the amniotic fluid metabolomic profile. The alteration of metabolic pathways in these studies mainly involve energy metabolism, hormone metabolism, oxidative stress and inflammation. No population study investigated the association between environmental toxicants and placental metabolomics. This systematic review provides evidence that prenatal exposure to a variety of environmental pollutants can affect maternal and fetal metabolomic characteristics. Integration of environmental toxicant exposure and metabolomics data in maternal-fetal samples is helpful to understand the interaction between toxicants and metabolites, so as to reveal the pathogenesis of fetal disease or diseases of fetal origin.

Abstract
Perfluorooctanesulfonate (PFOS) is a man-made chemical widely used in industrial products. Due to its high persistence, PFOS has been detected in most animal species including the human population, wild animals, and aquatic organisms. Both cross-sectional studies and laboratory animal studies have shown hepatotoxicity, renal toxicity, and reproductive toxicity caused by PFOS exposure. Recently, a limited number of PFOS studies have raised concerns about its potential immune system effects. However, the molecular mechanism underlying the immunotoxicity of PFOS remains unknown. In this study, we used primary human lymphocytes as a model, together with integrative omics analyses, including the transcriptome and lipidome, and bioinformatics analysis, to resolve the immune toxicity effects of PFOS. Our results demonstrated that PFOS could alter the production of interleukins in human lymphocytes. Additionally, PFOS exposure could dysregulate clusters of genes and lipids that play important roles in immune functions, such as lymphocyte differentiation, inflammatory response, and immune response. The findings of this study offer novel insight into the molecular mechanisms underlying the immunotoxicity of PFOS, and open the potential of using the identified PFOS-responsive genes and lipids as biomarkers for risk assessment.

Abstract
Polybrominated diphenyl ethers (PBDEs) are extensively used as brominated flame retardants in various factory products. As environmental pollutants, the adverse effects of PBDEs on human health have been receiving considerable attention. However, the precise fundamental mechanisms of toxicity induced by PBDEs are still not fully understood. In this study, the mechanism of cytotoxicity induced by 2,2',4,4'-tetrabromodiphenyl ether (BDE-47) was investigated by combining Seahorse XFp analysis and mass spectrometry-based metabolomics and flux approaches in PC12 cells, one of the most widely used neuron-like cell lines for investigating cytotoxic effects. The Seahorse results suggest that BDE-47 significantly attenuated mitochondrial respiration and enhanced glycolysis in PC12 cells. Additionally, metabolomics results revealed the reduction of TCA metabolites such as citrate, succinate, aconitate, malate, fumarate, and glutamate after BDE-47 exposure. Metabolic flux analysis showed that BDE-47 exposure reduced the oxidative metabolic capacity of mitochondria in PC12 cells. Furthermore, various altered metabolites were found in multiple metabolic pathways, especially in glycine-serine-threonine metabolism and glutathione metabolism. A total of 17 metabolic features were determined in order to distinguish potentially disturbed metabolite markers of BDE-47 exposure. Our findings provide possible biomarkers of cytotoxic effects induced by BDE-47 exposure, and elicit a deeper understanding of the intramolecular mechanisms that could be used in further studies to validate the potential neurotoxicity of PBDEs in vivo. Based on our results, therapeutic approaches targeting mitochondrial function and the glycolysis pathway may be a promising direction against PBDE exposure.

Li R, Huang X, Liang X, Su M, Lai KP, Chen J. Integrated omics analysis reveals the alteration of gut microbe-metabolites in obese adults. Brief Bioinform 2020; 22:5882185. [PMID: 32770198 DOI: 10.1093/bib/bbaa165] [Citation(s) in RCA: 22] [Impact Index Per Article: 5.5] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/28/2020] [Revised: 07/01/2020] [Accepted: 07/02/2020] [Indexed: 12/13/2022] Open
Abstract
Obesity, a risk to health, is a global problem in modern society. The prevalence of obesity was approximately 13% among world's adult population. Recently, several reports suggested that the interference of gut microbiota composition and function is associated with metabolic disorders, including obesity. Gut microbiota produce a board range of metabolites involved in energy and glucose homeostasis, leading to the alteration in host metabolism. However, systematic evaluation of the relationship between gut microbiota, gut metabolite and host metabolite profiles in obese adults is still lacking. In this study, we used comparative metagenomics and metabolomics analysis to determine the gut microbiota and gut-host metabolite profiles in six normal and obese adults of Chinese origin, respectively. Following the functional and pathway analysis, we aimed to understand the possible impact of gut microbiota on the host metabolites via the change in gut metabolites. The result showed that the change in gut microbiota may result in the modulation of gut metabolites contributing to glycolysis, tricarboxylic acid cycle and homolactic fermentation. Furthermore, integrated metabolomic analysis demonstrated a possible positive correlation of dysregulated metabolites in the gut and host, including l-phenylalanine, l-tyrosine, uric acid, kynurenic acid, cholesterol sulfate and glucosamine, which were reported to contribute to metabolic disorders such as obesity and diabetes. The findings of this study provide the possible association between gut microbiota-metabolites and host metabolism in obese adults. The identified metabolite changes could serve as biomarkers for the evaluation of obesity and metabolic disorders.

Abstract
As revealed in previous reports, calycosin is a functional flavonoid characterized with identified pharmacological activities. Most of evidences are used to demonstrate the anti-cancer benefits of calycosin, however, the existing study of anti-fatty liver medicated by calycosin is limitedly reported. Recently, an emerging avenue based on network pharmacology may contribute to excavate the biological targets and molecular mechanisms of calycosin for anti-fatty liver. In confirmatory experiments, the human and animal studies were subjected to verify some of bioinformatic results. Accordingly, bioinformatic data based on network pharmacology suggested that discoverable biotargets of calycosin for anti-fatty liver were aldehyde dehydrogenase (ALDH2), Niemann pick C1 (NPC1), high mobility group protein 1 (HMGB1), bilirubin UDP glucuronosyltransferase 1 (UGT1A1), mitogen-activated protein kinase 3 (MAPK3), epidermal growth factor receptor (EGFR), hydroxytryptamine receptor 2 (HTR2), migration inhibitory factor (MIF), cytochrome P450, family 19A1 (CYP19A1). Furthermore, all significant biological characteristics and mechanisms of to treat fatty liver were revealed in several. In human findings, the blood tests showed changed glucose and lipid contents, elevated insulin resistance and inflammatory stress. And fatty liver sections from patients resulted in negative expressions of ALDH2, NPC1, and positive HMGB1 expression. In a study in vivo, calycosin-treated high fat diet (HFD)-fed mice exhibited reduced liver weights, decreased fasting serum glucose and insulin, liver functional transaminases, blood lipids, metabolic enzymes, and inflammatory cytokines. And the data in gene tests displayed up-regulations of ALDH2, NPC1 mRNAs, and down-regulation of HMGB1 mRNA in calycosin-treated liver samples. Together, the current bioinformatic data demonstrate biological targets, functions and mechanisms of calycosin for anti-fatty liver. Interestingly, these bioinformatic findings can be partially verified with clinical and animal samples.

Abstract
Colorectal cancer (CRC) refers to a deadly carcinoma following potent invasiveness and metastasis in advanced stage. Unfortunately, existing anti-CRC medicine is insufficient for chemotherapy in addition to adverse effects. Consequently, the candidate natural ingredient for treating CRC needs to be further developed. Our previous experiments report that genistein exerts beneficial effects to inhibit CRC cells via an antiproliferative mechanism. Based on the metastatic characteristics of staging CRC, anti-invasive and antimetastatic pharmacological activities using genistein remain uninvestigated. The scientific purpose of this study was to disclose the antimetastatic mechanism by using human and cell culture/nude mice samples, followed by biochemical tests and immunoassays. In human study, these CRC cases resulted in increased transforming growth factor beta-1 (TGF-β1) levels, long noncoding RNA (lncRNA) TTTY18 expressions, followed with up-regulated Ki-67, serum and glucocorticoid regulated kinase 1 (SGK1), AktSer473 expressions. In a study in vitro, genistein-dosed CRC cells showed suppressed cell viability, promoted cell apoptosis, reduced Ki-67 positive cells, reduced cellular migration, down-regulated expressions of TTTY18, SGK1, AktSer473 , p38 MAPKTyr323 . In a further study in vivo, genistein-dosed tumor-bearing nude mice exhibited visibly reduced body mass, lowered tumorous TGF-β1 and TTTY18 contents. In addition, intracellular numbers of SGK1, AktSer473 , p38 MAPKTyr323 positive cells were reduced dose-dependently. Collectively, these human and experimentative findings reveal that genistein pharmacologically exerts the potential antimetastatic CRC effects, possibly through a molecular mechanism of inhibiting TTTY18/Akt pathway in CRC cells.

Abstract
Calycosin is a naturally occurring phytoestrogen, and it has the anti-nasopharyngeal carcinoma (NPC) action played by calycosin. However, the elaborate mechanisms of calycosin treating NPC remain to be unrevealed. In current report, a promising tool of network pharmacology method was used to uncover the anti-NPC targets and therapeutic mechanisms played by calycosin. Furthermore, were conducted to validate the bioinformatic findings in human and preclinical studies. As results, the bioinformatic findings showed the core anti-NPC targets played by calycosin included tumor protein p53 (TP53), mitogen-activated protein kinase 14 (MAPK14), caspase 8 (CASP8), mitogen-activated protein kinase 3 (MAPK3), caspase 3 (CASP3), receptor interacting protein kinase 1 (RIPK1), proto-oncogene c (JUN), and estrogen receptor 1 (ESR1). Concurrently, the top 20 biological processes and top 20 pharmacological pathways of calycosin treating NPC were identified and illustrated. In clinical data, NPC samples showed up-regulated expression of MAPK14, reduced TP53, and CASP8 expressions in comparison with those in non-NPC controls. As revealed in experimental data, calycosin-treated NPC cells resulted in reduced cell survival rate, increased cell apoptosis. In apoptosis-specific staining, calycosin-treated NPC cells exhibited elevated apoptotic cell number. Following the immunostaining assays, the results indicated increased TP53-, CASP8-positive cells, and reduced MAPK14-positive cells in calycosin-treated NPC cells and xenograft tumor sections. Altogether, the bioinformatic findings from network pharmacology reveal all core targets and mechanisms of calycosin treating NPC, and some of bioinformatic findings are identified using human and preclinical experiments. Notably, the screened biotargets may be potentially used to clinically treat NPC.

Abstract
Plumbagin (PL) pharmacologically plays the anti-proliferative effects in cancer cells, including effective suppression of colorectal cancer (CRC). However, the exact molecular mechanism of PL to treat CRC remains unclear. Using available SwissTargetPrediction and SuperPred databases, the anti-cancer biotargets of PL were identified, and the CRC-diseased targets were obtained through a DisGeNET database. The biological processes, and signaling pathways of PL to treat CRC were identified and visualized. Further, clinical and cell culture data were used to validate some bioinformatic findings. As shown in bioinformatics findings, 64 predictive biotargets of PL to treat CRC were collected, and 7 most important biotargets of tumor protein p53 (TP53), glyceraldehyde-3-phosphate dehydrogenase (GAPDH), mitogen-activated protein kinase 1 (MAPK1), E1A-associated protein p300 (EP300), poly (ADP-ribose) polymerase 1 (PARP1), nuclear factor kappa p65 protein (RELA), Bcl-2 like protein 1 (BCL2L1) were identified respectively. In addition, top 20 functional biological processes, signaling pathways of PL to treat CRC were screened and prioritized. In human study, CRC samples showed elevated expressions of neoplastic MAPK1, PARP1 mRNAs and reduced EP300 mRNA level. In cell culture study, PL-treated CRC cells resulted in down-regulated MAPK1, PARP1 mRNA expressions and up-regulation of EP300 mRNA level, characterized with suppressed cell proliferation. Taken together, the therapeutic biotargets and molecular mechanisms of PL to treat CRC were screened and identified by using a systematic pharmacology analysis, and some bioinformatic findings were validated in clinical and cell line experiments. Potentially, these hub biotargets may be the biomarkers for CRC detection and treatment.

Abstract
Calycosin is reportedly evidenced with pharmacologically treating bone cells. However, the comprehensive anti-osteosarcoma (OS) mechanisms of calycosin have not been uncovered. By using a systemic method of network pharmacology, the present study aimed to reveal potential anti-OS biotargets and molecular mechanisms played by calycosin. Moreover, human and animal experiments were conducted to verify the core biotargets of calycosin against OS. As results, all primary and core biotargets, biological processes, molecular pathways of calycosin against OS were revealed. Additionally, top 20 biological processes and pathways of calycosin against OS were identified. In human study, the OS sections resulted in reduced expressions of tumor protein p53 (TP53), Caspase-3 (CASP3), and elevated X-linked inhibitor of apoptosis protein (XIAP) expression in comparison with OS-free controls. As shown in cell culture study, calycosin-treated OS cells showed reduced cell proliferation, and promoted cell apoptosis. In TUNEL stains, calycosin resulted in elevated apoptotic cells. As showed in immunostaining, calycosin-treated OS cells exhibited intracellular up-regulation of TP53, CASP3 expressions, and decreased XIAP expressions. Taken together, the biological informational findings manifest the candidate and core biotargets, molecular functions and pathways of calycosin against OS. Attractively, these core biotargets may be used for effectively detecting and treating human OS.

Clinical characteristics of colorectal cancer patients and anti-neoplasm activity of genistein. Biomed Pharmacother 2020; 124:109835. [PMID: 31958764 DOI: 10.1016/j.biopha.2020.109835] [Citation(s) in RCA: 9] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/21/2019] [Revised: 12/29/2019] [Accepted: 01/06/2020] [Indexed: 12/29/2022] Open
Abstract
BACKGROUND Epidemiologically, the disease incidence of colorectal cancer (CRC) ranks the third among all malignant tumors, and its mortality is the second following lung cancer. If unmanaged, CRC will develop fatal invasiveness and metastasis. However, existing chemotherapy is limitedly effective to treat metastatic CRC. Genistein, a functional phytoestrogen, is found with potent pharmacological activity against cancer cells. Therefore, this study was designed to characterize the clinical signatures of human CRC and to conduct anti-CRC experiments using genistein. METHODS Briefly, the plasma, tumor, non-tumor samples of CRC patients were harvested for biological experiments, followed by analysis of clinical data. A pharmacological study in vitro of genistein for treating CRC cells was conducted accordingly. RESULTS In diagnostic data, molecular tumor biomarkers in CRC patients were detected in plasma samples, consistent with pathological and imaging diagnoses of CRC. Notably, carcinomatous expressions of miR-95, serum glucocorticoid kinase 1 (SGK1), B-cell lymphoma-2 (Bcl-2), extracellular regulated protein kinase 1 (Erk1) in human CRC were notably elevated when compared to those in non-tumor controls. In pharmacological experiments using cell culture model, genistein-treated CRC cells resulted in reduced cellular viability, elevated lactate dehydrogenase (LDH) content, increased apoptotic cells and TdT mediated dUTP nick end labeling (TUNEL)-positive cells following a dose-dependent manner. Interestingly, down-regulated expressions of endogenous miR-95, SGK1, Bcl-2, Erk1 were observed after genistein treatments in a dose-dependent way. CONCLUSIONS Collectively, the current clinical data indicate pathological markers of miR-95, SGK1, Erk1 in human CRC cases, and further experimental findings reveal that anti-CRC pharmacological mechanism using genistein was implicated in suppression of cellular miR-95, SGK1, Erk1 expressions. Together, genistein may be a promising bioactive compound for treating CRC.

Abstract
This article was designed by using a network pharmacological approach to reveal the therapeutic targets and molecular mechanisms of oxyresveratrol (Oxyres) treating colorectal cancer (CRC). Furthermore, several bioinformatic findings would be validated. Pathogenetic targets of CRC and pharmacological targets of Oxyres were identified by web-available databases. All identifiable biotargets were collected for functional enrichment analyses to reveal the biological processes and signaling pathways of Oxyres treating CRC. In addition, human CRC, non-CRC samples, and cell line study were used to validate the predictive biotargets of Oxyres treating CRC. In network pharmacological analyses, top therapeutic targets of mitogen-activated protein kinase 1 (MAPK1), insulin growth factor 1 (IGF1), hematopoietic prostaglandin D synthase (HPGDS), GTPase HRas (HRAS), and cytochrome P450 2C9 (CYP2C9) in Oxyres treating CRC were identified, respectively. As shown in functional analysis, biological processes of Oxyres treating CRC were mainly involved in modulating cell communication, signal transduction, apoptosis, cell motility, cell proliferation, and lipid metabolism. Furthermore, top 10 signaling pathways of Oxyres treating CRC were identified, respectively. In human study, CRC samples resulted in increased neoplastic expressions of Ki-67, MAPK1, IGF1, characterized with clinical imaging inspection, pathological diagnosis, and altered blood lipids in these CRC cases. In cell culture study, Oxyres-dosed CRC cells exhibited reduced cell proliferation, promoted cellular apoptosis. Furthermore, significantly decreased proteins of intracellular Ki-67, MAPK1, and IGF1 were observed in Oxyres-dosed cells when compared to those in controls. Collectively, anti-CRC pharmacological activity of Oxyres may be mainly associated with induction of apoptosis and suppression of cell proliferation as revealed in bioinformatic findings. In addition, all core biotargets and molecular mechanisms of Oxyres treating CRC are unveiled respectively. Interestingly, the identifiable MAPK1, IGF1 biotargets may be potential molecules for treating and screening CRC.
