In the realm of toxicology, understanding the intricate molecular interactions underlying heavy metal toxicity requires a holistic approach that transcends traditional disciplinary boundaries. Enter omics integration and systems toxicology-a powerful framework that leverages data from genomics, transcriptomics, proteomics, metabolomics, and other omics technologies to construct comprehensive networks of molecular interactions, unravelling the complex web of biological responses to heavy metal exposure. At the heart of this approach lies the concept of systems toxicology, which views biological systems as dynamic networks of interconnected molecules and pathways. By integrating data from multiple omics platforms, researchers can gain a more holistic view of cellular responses to heavy metal exposure, identifying key molecular players, pathways, and networks involved in toxicity. This integrative approach not only provides a deeper understanding of the mechanisms underlying heavy metal toxicity but also offers new opportunities for the identification of biomarkers of exposure and effect. Genomics, the study of an organism’s complete set of DNA, provides a foundation for understanding the genetic basis of susceptibility to heavy metal toxicity. Genome-wide Association Studies (GWAS) and other genomic approaches enable researchers to identify genetic variants associated with differential responses to heavy metal exposure, shedding light on individual variability in susceptibility and informing personalized risk assessment strategies. Transcriptomics, the study of an organism’s complete set of RNA transcripts, offers insights into changes in gene expression patterns in response to heavy metal exposure. High-throughput RNA sequencing (RNA-seq) and microarray technologies allow researchers to quantify gene expression levels across the entire genome, uncovering transcriptional signatures associated with metal exposure and identifying dysregulated pathways and biological processes. Proteomics, the study of an organism’s complete set of proteins, provides complementary information about changes in protein abundance, posttranslational modifications, and protein-protein interactions in response to heavy metal exposure. Mass spectrometrybased proteomic techniques enable the identification and quantification of thousands of proteins in complex biological samples, revealing alterations in protein expression, activity, and localization induced by metal toxicity. Metabolomics, the study of an organism’s complete set of small-molecule metabolites, offers insights into changes in metabolic pathways and biochemical processes in response to heavy metal exposure. Nuclear magnetic resonance spectroscopy and mass spectrometrybased metabolomics platforms enable the identification and quantification of metabolites in biological samples, uncovering metabolic signatures associated with metal exposure and toxicity. By integrating data from genomics, transcriptomics, proteomics, metabolomics, and other omics technologies, researchers can construct comprehensive networks of molecular interactions underlying heavy metal toxicity. These integrative networks provide a systems-level view of cellular responses to metal exposure, elucidating cross-talk between different molecular layers and identifying key nodes and pathways driving toxicity. Moreover, omics integration enables the identification of biomarkers of exposure and effect—biological indicators that reflect exposure to heavy metals and predict adverse health outcomes. By correlating omics signatures with clinical endpoints, such as disease risk or progression, researchers can develop biomarker panels for early detection, diagnosis, and monitoring of metal-induced health effects, paving the way for precision medicine approaches to environmental health.
