Summary: Many insecticides and fungicides can disrupt the endocrine system in placenta, inhibiting the activity of a key enzyme called HSD3B1. Triclosan, triflumizole, and oxine were found to effectively inhibit the activity of HSD3B1 in both human and rat placenta.

Summary: This study evaluated the placental toxicity of Forskolin in pregnant women. The results showed that Forskolin activated P2X7 receptors and disrupted the secretion of estradiol, progesterone, hPL, and hyperglycosylated hCG in placental cells. This suggests that Forskolin may pose risks to pregnant women and should be restricted.

Summary: Preeclampsia (PE) is a disease that occurs after 20 weeks of pregnancy and is characterized by new onset hypertension and albuminuria or other end-organ damage. It is a major complication of pregnancy that can increase morbidity and mortality in pregnant women and fetuses, causing significant social burden. Recent research suggests that exposure to environmental xenobiotic compounds, particularly endocrine disruptors, may contribute to the development of PE. However, the specific mechanisms underlying this relationship remain unclear. This paper reviews the role and potential mechanism of PE induced by exogenous chemicals and provides an outlook on the environmental etiology of PE.

Summary: This study found that di-n-butyl phthalate (DBP) exposure can lead to persistent effects on testosterone synthesis and spermatogenesis in adult male mice, resulting in decreased testosterone levels. The study also revealed increased levels of key cells and proteins, including steroidogenic enzymes, oxidative stress markers, and germ cell markers, in response to DBP exposure.

Summary: Polychlorinated biphenyls (PCBs), organochlorine pesticides (OCPs), polybrominated diphenyl ethers (PBDEs), and polycyclic aromatic hydrocarbons (PAHs) are endocrine-disrupting chemicals (EDCs) that are concerning for fetal exposure. Placenta can serve as a good indicator for potential fetal exposure. This study compared the presence of these chemicals in human and dog placentas, and found differences in the types and concentrations of pollutants, indicating species-specific effects.

Summary: The study found that high concentrations of acetaminophen can affect gene and protein expression in placental JEG-3 cells, disrupting the secretion of estradiol, which plays a crucial role in the development of reproductive organs and the brain in the fetus. This highlights the potential for acetaminophen to interfere with hormone regulation during pregnancy and emphasizes the need for further research on its endocrine disruption activity during fetal development.

Summary: Dietary phytoestrogens, such as diosgenin, pose a contamination threat to environmental health due to their estrogen-mimicking and endocrine-disrupting effects. This study evaluated the reproductive and endocrine toxicity of diosgenin in albino mice, finding that chronic exposure disrupted reproductive functions and caused transgenerational reproductive toxic effects in offspring. Thus, caution should be exercised in the use of diosgenin in food products and medical applications.

Summary: Good-quality reproductive cells are crucial for reproduction. Endocrine disruptors, such as the novel brominated flame retardant TBC, have been found to negatively affect spermatogenesis and steroidogenesis. This study reveals that TBC impacts the hormonal system, with the involvement of ER alpha, but the exact mechanism remains unknown. Additionally, the levels of proteins and enzymes involved in steroid conversion decrease, suggesting dysregulation of steroid biosynthesis. The findings also show a decrease in steroid hormone production and secretion in the presence of TBC. These results highlight the potential impact of TBC on male fertility.

Summary: This study comprehensively evaluated the safety issues of BP-3 and BP-1 in the human body and found that they have endocrine disrupting properties. HBM studies showed that North Americans have potential exposure levels 10 to 20 times higher than Europeans and Asians. Therefore, it is recommended to use commercially available sunscreens with inorganic UV filters for susceptible populations.

Summary: Urinary extracellular vesicles (uEVs) contain valuable information about the urogenital tract organs and can be used to study disease pathophysiology and as diagnostic and prognostic biomarkers. Analysis of mRNA within uEVs provides a non-invasive way to assess gene expression patterns of renal cells. Studies have shown that mRNA from uEVs can provide insights into hypertension-related genes and their expression changes. This research has the potential to enhance our understanding of hypertension pathophysiology and lead to more personalized investigative and diagnostic approaches.

Summary: Liver cancer, especially hepatocellular carcinoma (HCC), is the third leading cause of cancer-related deaths globally. The emerging importance of gut homeostasis in HCC pathogenesis, patterns of dysbiosis in HCC patients, and potential role in diagnosis highlight the potential for improving treatment and prevention. Although clinical studies are lacking, animal models suggest that modulation of gut microbiota by probiotics could be a new approach to treat or prevent HCC development.

Summary: The gastrointestinal tract consists of four main barriers: microbiological, chemical, physical, and immunological, which play crucial roles in maintaining its homeostasis. Microbiota have been shown to influence the integrity of the GI tract barrier, and alterations in gut microbiome can lead to increased intestinal permeability. Nonalcoholic Fatty Liver Disease (NAFLD), one of the most common chronic liver diseases, has been linked to changes in gut microbiota and barrier integrity, but the causal relationship between them is still not fully understood.

Summary: Innovative solutions are needed for the treatment of bacterial infections and exploring the immune system for therapeutic strategies is a promising approach. However, the immune system has a dual role and excessive immune responses can cause disease. Modulating innate immunity shows promise as a therapy for urinary tract infections, but further research is required.

Summary: Theabrownin (TB), an antioxidant from Pu-erh tea, has been found to inhibit tumor formation and potentially be a promising candidate for colorectal cancer (CRC) treatment. TB exerts its antitumor effects by suppressing cell proliferation and enhancing apoptosis through modulation of PI3K/Akt/mTOR signaling pathway. TB also modifies the gut microbiota composition, increasing the abundance of short chain fatty acid-producing bacteria and decreasing CRC-related bacteria. This study provides valuable insights into potential therapeutic options for CRC.

Summary: Long-term therapeutic efficacy of alpha1-oleate can be improved by repeated treatment cycles and combining with low-dose chemotherapy. One treatment cycle of alpha1-oleate alone or in combination with Epirubicin or Mitomycin C arrested bladder tumor growth and provided at least 4 weeks of protection. Repeated treatment cycles extended the protective effect and reduced bladder pathology and cancer-specific gene expression.

Summary: Triple-negative breast cancer (TNBC) is a highly lethal subtype of breast cancer. Crocin-loaded liposomes showed enhanced cytotoxicity when combined with chemotherapy drug doxorubicin (DOX) in MDA-MB-231 cells. The liposome formulation had monodisperse distribution with an average size of 80 nm, about 70% encapsulation efficiency, and 11% loading capacity. The study suggested that crocin-loaded liposomes can be a promising approach against tumor cells, especially when combined with DOX.
