Summary: DNA methylation, as an epigenetic modification, has been consistently associated with various human traits and diseases. It has the potential to serve as a disease biomarker by reflecting environmental exposures and predicting disease onset. DNA methylation patterns are more stable and easier to measure compared to transcriptomic or proteomic patterns, making them ideal for tracking different environments and risk factors. DNA methylation-based predictors have shown promise in being more accurate than self-reported or measured phenotypes, and may have applications in clinics.

Summary: A previous study found positive associations between maternal urinary concentrations of triclosan and placental DNA methylation in male fetuses. This study aimed to validate and expand on these findings by examining triclosan exposure and placental DNA methylation in a cohort of male and female fetuses. The results confirmed associations between triclosan and certain genes in both sexes, with the majority of associations being positive and mapping to imprinted genes. The study also identified mediation effects of placental tissue heterogeneity on the associations. In conclusion, triclosan exposure is associated with placental DNA methylation, particularly in imprinted genes.

Summary: The study identified common 5-hmC and 5-mC signatures in two populations exposed to varying levels of inorganic As, but differences in As-related epigenetic sites across the study populations may also reflect low and high As-specific associations. This work contributes to a deeper understanding of potential epigenetic dysregulations of As, with further research needed to confirm biological consequences associated with DIP2C epigenetic regulation and investigate the role of 5-hmC and 5-mC separately in As-induced health disorders at different exposure levels.

Summary: The evidence regarding the association between prenatal alcohol exposure and offspring DNA methylation is inconclusive. There is insufficient evidence to support global disruption of DNA methylation from prenatal alcohol exposure. Limited evidence suggests hypomethylation at IGF2/H19 regions within somatic tissues. Methylome-wide association studies (MWAS) investigating the effects of prenatal alcohol exposure on offspring DNA methylation show inconsistent results. Further research is needed, especially in populations with Fetal Alcohol Spectrum Disorder (FASD), to establish reproducible associations.

Summary: Epigenetic information, inherited through DNA methylation, plays a crucial role in defining tissue identity. This study reveals that methylation entropy, which represents stochastic changes in DNA methylation, is associated with specific DNA binding motifs, regulatory DNA, and CpG density. Additionally, the contribution of methylation entropy to developmental patterns is comparable to that of methylation mean, and it is associated with conserved sequence and chromatin features. Furthermore, methylation entropy is directly related to gene expression variability in development, suggesting its involvement in developmental plasticity.

Summary: Due to its simple process, environmental friendliness, and low operating costs, biometallurgy has become a popular technology for metals recovering from low-grade ores and tailings. An optimized agar was used to isolate and grow functional bacteria, resulting in the successful isolation of six functional stains. These strains were further tested for their ability to leach metals from polymetallic sulfide tailings, with significant improvements observed when the strains were mixed together. The selection of leaching process should be based on tailings composition and target metals.
