    Abstract According to epidemiological studies, phthalate exposure is associated with an increased risk of obesity in children and adults; however, these observations remain debatable. Therefore, we performed a systematic review and meta-analysis of the current literature to explore the effects of phthalate exposure on obesity. A systematic search was performed from inception to July 2022 in PubMed, EMBASE, Scopus, and Web of Science. Quality assessment was completed using criteria modified from Newcastle-Ottawa Scale (NOS) for the included studies. Meta-analysis showed that childhood exposure to MnBP, MBP, MEP, MiBP, and MECPP was positively correlated with obesity. In adults, MMP, MEP, and MiBP were positively correlated with adult abdominal obesity, while MEHHP, MECPP, and MCOP were positively correlated with adult general obesity. Subgroup analysis revealed that the positive correlation was particularly significant in women, as well as in Europe and the United States. Overall, a substantial association exists between phthalate exposure and obesity in children and adults. Sex and study site may provide limited sources of heterogeneity.

    Abstract Di(2-ethylhexyl) phthalate (DEHP) is a ubiquitous pollutant that results in hepatotoxicity. However, an understanding of the systematic mechanism of hepatic injury caused by DEHP remains limited. Here, we performed a comprehensive metabolomics and transcriptomics analyses to describe hepatic responses of rats to long-term DEHP exposure and, together with pathology and functional injury of liver, systematically analyzed the pathogenesis and mechanisms of liver damage. SD rats were exposed to 0 and 600 mg/kg/day DEHP for 12 weeks. Thereafter, biochemical indicators and histopathological changes regarding liver function were detected. Metabolomics and transcriptomics profiles of rat liver samples were analyzed using a UPLC-MS/MS system and Illumina Hiseq 4000, respectively. DEHP induced hepatocyte structural alterations and edema, depressed monooxygenase activity, decreased antioxidant activities, aggravated oxidative damage, blocked the tricarboxylic acid cycle and respiratory chain, and disturbed glucose homeostasis in the liver. These findings indicate that reactive oxygen species play a major role in these events. Overall, this study systematically depicts the comprehensive mechanisms of long-term DEHP exposure to liver injury and highlights the power of metabolomics and transcriptomics platforms in the mechanistic understanding of xenobiotic hepatotoxicity.

    Abstract Given the lack of research on the schoolchildren exposure to PM2.5-bound PHAs in northeast China, we investigated the effects of exposure to ambient benzo[b]fluoranthene (BbFA) and dibenz[a,h]anthracene (DahA) bound to PM2.5 on pulmonary ventilation dysfunction (PVD) and small airway dysfunction (SAD). PM2.5 samples at two schools (A and B) were collected, and the concentrations of PM2.5-bound 4-6-ring PAHs were analyzed. PVD and SAD were evaluated by pulmonary function tests in 306 students while urinary MDA and CRP levels were measured. The results confirmed that ambient PM2.5-bound 4-6-ring PHA levels were significantly higher and the PVD and SAD incidence in schools A and B were increased during the heating season. We found that PM2.5-bound BbFA, BkFA, BaP, and DahA levels were only correlated with SAD in schoolchildren; the correlation coefficients of BbFA and DahA were the highest effect estimates, possibly due to altered MDA levels. Therefore, this research enables us to better understand the effects of exposure to ambient PM2.5-bound PHAs on pulmonary function parameters. Our results also showed that identification of hazardous PM2.5-bound BbFA and DahA to health is crucial for preventing the respiratory-related diseases.

    Abstract Di(2-ethylhexyl) phthalate (DEHP) is widely used and has been implicated in hepatotoxicity, although the mechanism is unclear. Here, we investigated the effect of DEHP on hepatic cholesterol metabolism in SD rats exposed to 0 and 300 mg/kg/day DEHP for 12 weeks. An RNA-Seq analysis was performed to describe the hepatic responses to long-term DEHP exposure in combination with serological and oxidative stress parameter measurements. DEHP increased the serum levels of total cholesterol (TC), high-density lipoprotein (HDL), and alanine transaminase (ALT). Moreover, DEHP increased the content of malondialdehyde (MDA) and decreased antioxidant enzyme activities in the liver. Transcriptomic results revealed that DEHP dramatically changed the cholesterol metabolism pathway and oxidation-reduction process and depressed gene expression involved in cholesterol efflux and monooxygenase activity. Total antioxidant capacity (T-AOC) positively correlated with Abcg5 and Abcg8. Overall, this study showed the mechanisms underlying hepatotoxicity caused by DEHP, providing new insights into understanding DEHP poisoning.

    Abstract Objective: Di-(2-ethylhexyl) phthalate (DEHP) is a ubiquitous environmental contaminant. As an endocrine disruptor, it seriously threatens human health and ecological environmental safety. This study examines the impact of intervention with soybean isoflavones (SIF) on DEHP-induced toxicity using a metabonomics approach.
    Methods: Rats were randomly divided into control (H), SIF-treated (A, 86 mg/kg body weight), DEHP-treated (B, 68 mg/kg), and SIF plus DEHP-treated (D) groups. Rats were given SIF and DEHP daily through diet and gavage, respectively. After 30 d of treatment, rat urine was tested using UPLC/MS with multivariate analysis. Metabolic changes were also evaluated using biochemical assays.
    Results: Metabolomics analyses revealed that p-cresol glucuronide, methyl hippuric acid, N1-methyl-2-pyridone-5-carboxamide, lysophosphatidycholine [18:2 (9Z, 12Z)] {lysoPC [18:2 (9Z, 12Z)]}, lysoPC (16:0), xanthosine, undecanedioic acid, and N6-acetyl-l-lysine were present at significantly different levels in control and treatment groups.
    Conclusion: SIF supplementation partially protects rats from DEHP-induced metabolic abnormalities by regulating fatty acid metabolism, antioxidant defense system, amino acid metabolism, and is also involved in the protection of mitochondria.

    Abstract The study objectives were to investigate the relationship between early exposure to genistein and obesity in young adulthood and to evaluate changes in reproductive health during puberty and adulthood following in utero exposure to genistein. Thirty-two female rats were randomized into four groups; low dose 400 mg genistein/kg diet group (LG), mid-dose 1200 mg genistein/kg diet group (MG), high dose 3600 mg genistein/kg diet group (HG), and control group without genistein diet (CON). Rats were fed genistein at the beginning of pregnancy along with a high-fat diet. Pups were sacrificed at week 4 and week 8 after birth. High performance liquid chromatography (HPLC) results showed a correlation between maternal genistein intake and genistein concentration in pups' plasma. Compared to CON, body weight reduced significantly in male HG group at week 8. No statistical differences were found in plasma estradiol (E2), testosterone (T), interleukin (IL)-6, and C-reactive protein (CRP) levels with early genistein exposure. Furthermore, uterine histopathology showed notable changes in groups HG and MG compared with CON at week 4 and week 8. In conclusion, maternal genistein supplement could reduce body weight in male pups and alter uterine histopathology in female pups.
