Article Abstract
Epigenetic modifications control gene expression and are essential for turning genes on and off to regulate and maintain differentiated cell types. Epigenetics are also modified by a multitude of environmental exposures, including diet and pollutants, allowing an individual's environment to influence gene expression and resultant phenotypes and clinical outcomes. These epigenetic modifications due to gene-environment interactions can also be transmitted across generations, raising the possibility that environmental influences that occurred in one generation may be transmitted beyond the second generation, exerting a long-lasting effect. In this review, we cover the known mechanisms of epigenetic modification acquisition, reprogramming and persistence, animal models and human studies used to understand multigenerational epigenetic transmission, and examples of environmentally induced epigenetic change and its transmission across generations. We highlight the importance of environmental health not only on the current population but also on future generations that will experience health outcomes transmitted through epigenetic inheritance.

The uncharted effects of cadmium and cesium on circadian syndrome (CircS), an emerging circadian rhythm disorder drawing considerable attention, and underlying mechanisms warrant exigent elaboration. Data of 11141 subjects from National Health and Nutrition Examination Survey 2005-2018 were incorporated to investigate separate-, joint-/interaction-, and mixture-effects of urinary cadmium and cesium on prevalent CircS risk exploiting survey weight regression and quantile g-computation. The underlying mechanisms were probed by network toxicological analysis.

This study evaluated the chemical profile of toothpastes (TPs) and mouthrinses (MRs) and their effects on tooth enamel ultrastructure, and the viability of human dental pulp fibroblasts (hDPF). Four TPs and MRs containing different remineralizing agents (arginine, potassium nitrate, pro arginine, and stannous chloride) were analyzed for pH, titratable acidity (TA), and ion concentrations (Ca, K, Na). Enamel ultrastructure was evaluated using Fourier-transform infrared (FTIR) spectroscopy and scanning electron microscopy (SEM).

Background: Hyperthermia (HT), while a cancer treatment approach, isn't always effective alone. Therefore, identifying hyperthermia enhancers is crucial. We demonstrated that Mito-TEMPO ([2-[(1-Hydroxy-2,2,6,6-tetramethylpiperidin-4-yl) amino]-2-oxoethyl]-triphenylphosphanium, MT) acts as a potent thermosensitizer, promoting cell death in human cervical cancer (HeLa) cells.

Tralopyril (TP), a representative bromopyrrolonitrile, functions as a broad-spectrum insecticide, raising growing concerns about its potential impact on aquatic organisms and human intestinal health. However, the key targets and toxicity mechanisms underlying TP-induced enteritis remain unclear. In this study, we utilized network toxicology combined with molecular docking to comprehensively explore the potential molecular mechanisms underlying TP-induced enteritis.

As key pollinators, bees are increasingly threatened by environmental stressors such as heavy metals, pesticides, and temperature fluctuations, which can cause oxidative stress and disrupt cellular homeostasis. Glutathione S-transferases (GSTs) play crucial roles in antioxidant defense and detoxification, yet systematic studies on bee GST families remain limited. Here, we conducted a genome-wide analysis of cytosolic GST genes in 13 bee species, identifying 146 genes in total.
