Chlorpyrifos induces placental oxidative stress and barrier dysfunction by inducing mitochondrial apoptosis through the ERK/MAPK signaling pathway: In vitro and in vivo studies. THE SCIENCE OF THE TOTAL ENVIRONMENT 2023; 903:166449. [PMID: 37634732 DOI: 10.1016/j.scitotenv.2023.166449] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/25/2023] [Revised: 08/15/2023] [Accepted: 08/18/2023] [Indexed: 08/29/2023]
Abstract
Chlorpyrifos (CPF) is an organophosphorus pesticide that is widely used in agricultural production and residential environments worldwide. In this study, we determined the harmful effects and toxicological mechanism of CPF in porcine trophectoderm (pTr) cells and the placenta of female mice during pregnancy. The findings revealed that CPF significantly decreased cell viability and increased intracellular lactate dehydrogenase (LDH) release in pTr cells. Similarly, CPF induced reproductive toxicity in pregnant maternal mice, including decreased maternal, fetal, and placental weights. Moreover, following CPF treatment, pTr cells and the placenta of female mice showed significant apoptosis. JC-1 staining and flow cytometry analysis also revealed that the mitochondrial membrane potential (MMP) of pTr cells treated with CPF was significantly depolarized. Additionally, CPF can induce an increase in reactive oxygen species (ROS) and barrier dysfunction in pTr cells and the placenta of female mice. We further verified that CPF-induced mitochondrial apoptosis is mediated by the MAPK signaling pathway, as shown by using of small molecular inhibitors of related proteins. Also, CPF-induced oxidative stress, barrier dysfunction, and mitochondrial apoptosis in pTr cells were alleviated by U0126, an inhibitor of the ERK/MAPK signaling pathway. These findings suggested that exposure to CPF in early pregnancy might be a potential risk fator affecting placental formation and function in humans and animals.

Abstract
To investigate the effects of molybdenum (Mo) on apoptosis of lymphocytes and changes of peripheral blood in sheep, a total of 20 5-month-old healthy female sheep were randomly divided into five groups of 4 and orally administered with water containing Na2MoO4·2H2O (0, 5, 10, 20, and 50 mg/kg BW/day) for 28 days. Jugular vein blood was taken on the 0th, 7th, 14th, 21st, and 28th day of Mo treatment, respectively. On the 28th day, the spleen and thymus were removed for observing histopathology and apoptosis-related DNA damage by hematoxylin and eosin (HE) staining and TdT‑mediated dUTP Nick-End Labeling (TUNEL) staining, respectively. The blood routine indexes were determined by an automatic blood analyzer. Further, the apoptosis of lymphocytes and changes in mitochondrial membrane potential (MMP) of peripheral blood were analyzed by flow cytometry. Results showed that excessive Mo induced apoptosis-related DNA damage in the splenocytes and thymocytes and significantly increased the apoptosis indexes of the splenocytes and thymocytes (P < 0.01). Furthermore, the treatment with excessive Mo significantly decreased the MMP (P < 0.01) and promoted apoptosis in peripheral blood lymphocytes (P < 0.01). And the number of WBC, Lymph, Gran, and RBC and the indexes of HGB and HCT were also significantly decreased (P < 0.05 or P < 0.01), while RDW was significantly increased by excessive Mo (P < 0.05 or P < 0.01). In conclusion, excessive Mo-induced DNA damage and apoptosis of the lymphocytes changed the RBC-related indexes of the peripheral blood in sheep.

Abstract
IntroductionColorectal cancer (CRC) is one of the most prevalent cancers globally with a high mortality rate. Predicting prognosis using disease progression and cancer pathologic stage is insufficient, and a prognostic factor that can accurately evaluate patient prognosis needs to be developed. In this study, we aimed to infer a prognostic gene signature to identify a functional signature associated with the prognosis of CRC patients.MethodsFirst, we used univariate Cox regression, least absolute shrinkage and selection operator (lasso) regression, and multivariate Cox regression analyses to screen genes significantly associated with CRC patient prognosis, from colorectal cancer RNA sequencing data in The Cancer Genome Atlas (TCGA) database. We then calculated the risk score (RS) for each patient based on the expression of the nine candidate genes and developed a prognostic signature.ResultsBased on the optimal cut-off on the receiver operating characteristic (ROC) curve, patients were separated into high- and low-risk groups, and the difference in overall survival between the two groups was examined. Patients in the low-risk group had a better overall survival rate than those in the high-risk group. The results were validated using the GSE72970, GSE39582, and GSE17536 Gene Expression Omnibus (GEO) datasets, and the same conclusions were reached. ROC curve test of the RS signature also indicated that it had excellent accuracy. The RS signature was then compared with traditional clinical factors as a prognostic indicator, and we discovered that the RS signature had superior predictive ability.ConclusionThe RS signature developed in this study has excellent predictive power for the prognosis of patients with CRC and broad applicability as a prognostic indicator for patients.

Anthelmintic efficacy of oxibendazole against gastrointestinal nematodes in swine. REVISTA BRASILEIRA DE PARASITOLOGIA VETERINARIA = BRAZILIAN JOURNAL OF VETERINARY PARASITOLOGY : ORGAO OFICIAL DO COLEGIO BRASILEIRO DE PARASITOLOGIA VETERINARIA 2022; 31:e018321.

Abstract
In swine production, parasites, especially gastrointestinal helminths, generate considerable economic losses. Therefore, effective control measures, such as the use of the correct anthelmintics, are of paramount importance for maintaining profitability. The aim of the present study was to evaluate the efficacy of the anthelmintic oxibendazole, administered orally, in pigs (non-industrial) naturally infected with gastrointestinal nematodes. To that end, we selected 18 pigs naturally parasitized by gastrointestinal nematodes, as determined by examination of fecal samples (eggs per gram (EPG > 500) of feces), and divided them into two groups: treated (with a 10-day course of oxibendazole) and control (untreated). After the treatment period, the animals were euthanized. During necropsy, the helminths in the gastrointestinal tract were identified and quantified. The species identified were, in order of occurrence, Ascaris suum, Trichuris suis, Oesophagostomum dentatum, and Hyostrongylus rubidus. In Brazilian swine herds, traditional (non-industrial) production systems can favor the transmission of helminths. We found that treatment with oxibendazole was 100% effective against A. suum and H. rubidus, whereas it was 99.65% effective against O. dentatum and 99.20% effective against T. suis, significantly reducing helminth counts (P < 0.01 for all). We conclude that oxibendazole is effective in controlling the main helminths in swine.

Abstract
Significant porcine embryonic loss occurs during conceptus morphological elongation and attachment from d 10 to 20 of pregnancy, which directly decreases the reproductive efficiency of sows. A successful establishment of pregnancy mainly depends on the endometrium receptivity, embryo quality, and utero-placental microenvironment, which requires complex cross-talk between the conceptus and uterus. The understanding of the molecular mechanism regulating the uterine-conceptus communication during porcine conceptus elongation and attachment has developed in the past decades. Reactive oxygen and nitrogen species, which are intracellular reactive metabolites that regulate cell fate decisions and alter their biological functions, have recently reportedly been involved in porcine conceptus elongation and attachment. This mini-review will mainly focus on the recent researches about the role of reactive oxygen and nitrogen species in regulating porcine embryo development during the pre-implantation period.
