DNA methylation signatures of arsenic exposure and obesity.

ABSTRACT: Emerging evidence suggests a link between environmental pollution and epigenetic alterations, prompting the need for comprehensive investigations into the relationship between pollutants and health conditions in human populations. This study investigates the interplay between obesity and exposure to toxic metals, examining clinical, serum metal concentrations, and epigenetic signatures. Our approach included serum metal concentration analysis by inductively coupled plasma mass spectrometry and epigenetic analysis using 450k Illumina BeadChips data. Singular value decomposition and linear regression models were used to identify metal associations with DNA methylation. Marked differences were evident in weight, body mass index, glycaemia, High Density Lipoprotein cholesterol (HDL-c), and tri
