Tri-o-tolyl phosphate impedes implantation: Malfunction of mitochondria and disruption of calcium homeostasis through MAPK and AKT signaling cascades.

Tri-o-tolyl phosphate (TOTP), a flame retardant containing aryl compounds, is widely used in human living environments owing to its several applications. However, Due to the overuse of TOTP, its residue has been identified in various environments and non-targeted organisms, including humans. Although extensive research is being conducted to address the toxicity of this substance, its potential reproductive toxicity in females has not been sufficiently studied.

Toxic effects of dibutyl phthalate on trophoblast through mitochondria mediated cellular dysfunction.

Dibutyl phthalate is a chemical commonly used as a plasticizer in the production of daily necessaries, such as cosmetics and toys. Although several toxic effects of dibutyl phthalate have been confirmed, those related to pregnancy are unknown. Trophoblasts are critical for fetal and placental development, and trophoblast damage may cause preeclampsia.

Female reproductive disease, endometriosis: From inflammation to infertility.

Despite the fact that endometriosis is a common gynecological disease that occurs in 10% of women of reproductive age, the pathogenesis and treatment strategy are not clear to date. Endometriosis patients are commonly characterized by adhesions in the pelvis or ovaries, which leads to prolonged inflammation in the abdominal cavity. To handle the chronic inflammation, changes of immune cells, including T cells, NK cells, and macrophage, are accompanied.

In vitro and in silico study of the synergistic anticancer effect of alpinumisoflavone with gemcitabine on pancreatic ductal adenocarcinoma through suppression of ribonucleotide reductase subunit-M1.

A highly aggressive neoplastic disease, pancreatic ductal adenocarcinoma (PDAC) is documented as the third chief cause of cancer-associated mortality in both sexes combined in the United States. For decades, gemcitabine-based chemotherapy has been embraced as a cornerstone drug for the treatment of PDAC. However, there have been several unsolved problems, including cytotoxicity, and chemoresistance.

Evaluation of organ developmental toxicity of environmental toxicants using zebrafish embryos.

There is increasing global concern about environmental pollutants, such as heavy metals, plastics, pharmaceuticals, personal care products, and pesticides, which have been detected in a variety of environments and are likely to be exposed to nontarget organisms, including humans. Various animal models have been utilized for toxicity assessment, and zebrafish are particularly valuable for studying the toxicity of various compounds owing to their similarity to other aquatic organisms and 70% genetic similarity to humans. Their development is easy to observe, and transgenic models for organs such as the heart, liver, blood vessels, and nervous system enable efficient studies of organ-specific toxicity.

Propanil impairs organ development in zebrafish by inducing apoptosis and inhibiting mitochondrial respiration.

Propanil, an anilide herbicide, has frequently been detected in surface waters in Europe and the United States, largely due to its use in paddy cultivation areas. Particularly in specific regions like Sri Lanka, propanil is considered a potential cause of certain diseases and toxicities due to its high environmental runoff; however, there has been little research on its developmental toxicity. In the present study, we confirmed the developmental toxicity of propanil in zebrafish embryos exposed to 0, 2, 5, and 6 mg/L based on the LC value.

In vitro and in silico assessment of cytotoxicity of dinitramine via calcium dysregulation and mitochondrial dysfunction in bovine mammary glands.

The herbicide market is expanding rapidly due to the global increase in herbicide usage. Dairy cows are susceptible to herbicide exposure through the ingestion of contaminated plants, which can adversely affect the mammary gland health and reduce milk production. Dinitramine, a synthetic herbicide in the dinitroaniline family, is typically used to control weeds by inhibiting their sprouting and root development.

Alpinumisoflavone ameliorates HO-induced intracellular damages through SIRT1 activation in pre-eclampsia cell models.

Pre-eclampsia (PE) is classified as pregnancy-specific hypertensive disease and responsible for severe fetal and maternal morbidity and mortality, which influenced an approximate 3 ∼ 8 % of all pregnancies in both developed and developing countries. However, the exact pathological mechanism underlying PE has not been elucidated and it is urgent to find innovate pharmacotherapeutic agents for PE. Recent studies have reported that a crucial part of the etiology of PE is played by placental oxidative stress.

Impacts of tolylfluanid on implantation and placental development: Disruption of mitochondrial function and implantation-related gene expression in vitro and in vivo.

Tolylfluanid is a widely used pesticide and antifouling agent in agricultural and marine industries and is recognized as a potential endocrine disruptor. However, the toxicological effects of tolylfluanid on the placenta development was not elucidated. This study used trophoblastic cell (HTR-8/SVneo cell) and endometrial cell (T HESCs) lines as in vitro model and mouse models as in vivo model to investigate the toxic effects of tolylfluanid on implantation-associated cell and placenta development during early pregnancy.

Flusilazole induced developmental toxicity, neurotoxicity, and cardiovascular toxicity via apoptosis and oxidative stress in zebrafish.

Flusilazole is a well-known triazole fungicide applied to various crops and fruits worldwide. Flusilazole residues are frequently detected in the environment, and many researchers have reported the hazardous effects of flusilazole on non-target organisms; however, the developmental toxicity of flusilazole has not been fully elucidated. In this study, we investigated flusilazole-induced developmental defects in zebrafish, which are used in toxicology studies to assess the toxic effects of chemicals on aquatic species or vertebrates.

Therapeutic effects of S-allyl-L-cysteine in a mouse endometriosis model and its immunomodulatory effects via regulation of T cell subsets and cytokine expression.

Background: Endometriosis is a female hormone-dependent gynecological disorder characterized by chronic inflammation. Therefore, the development of novel treatment strategies that can diminish the side effects of the long-term use of hormone-based drugs has been emphasized. S-Allyl-L-cysteine (SAC) is the major constituent of aged garlic extracts.

Brief guidelines for zebrafish embryotoxicity tests.

There has been growing emphasis on environmental pollutants, including heavy metals, pesticides, and nanoplastics, owing to the escalating significance of environmental pollution as a major global issue. Various toxicities induced by these compounds have been consistently reported, and many cell lines and animal models have been used in toxicity studies. Zebrafish are one of the most widely used animal models for verifying the toxic effects of environmental pollutants, owing to their many advantages.

Beta-cyfluthrin impairs implantation process by inducing mitochondrial defects and changes in reactive oxygen species-mediated signaling pathways in porcine trophectoderm and uterine luminal epithelial cells.

Pyrethroid insecticides, such as beta-cyfluthrin, are used extensively globally, including in households and agriculture, and have been detected in the milk and urine of humans and cattle. Beta-cyfluthrin exhibits toxic effects, including neurotoxicity and male reproductive toxicity; however, few studies have investigated female reproductive toxicity despite its wide environmental distribution. The present study investigates effects of beta-cyfluthrin on implantation in porcine cells (pTr from the trophectoderm and pLE from the endometrial luminal epithelium).
