Heavy metal exposure remains a significant environmental and public health issue, as prolonged or high-level exposure to toxic metals such as lead, cadmium, arsenic, and mercury can result in various health complications, including neurological disorders, cardiovascular diseases, and cancers. Identifying early biomarkers of exposure is crucial for timely intervention and reducing the long-term effects of heavy metals on human health. In recent years, microRNAs have emerged as promising biomarkers for detecting heavy metal exposure, offering a noninvasive and sensitive method for monitoring environmental toxins. The impact of heavy metals on human health is largely due to their ability to induce oxidative stress, inflammation, and disruption of normal cellular function. This interference can lead to altered gene expression, which may be reflected in changes to the levels of specific miRNAs. Recent studies have demonstrated that miRNAs can act as sensitive indicators of heavy metal exposure, as they reflect changes in gene expression and cellular pathways that are disturbed by metal toxicity. For example, miRNAs have been shown to be involved in oxidative stress responses, inflammatory pathways, and DNA repair mechanisms, which are all affected by heavy metal exposure. Studies have shown that miRNAs can be altered even at low levels of exposure, allowing for early diagnosis before significant damage occurs. This early detection is crucial for preventing long-term health effects, particularly for vulnerable populations such as children, pregnant women, and workers in industries with high exposure risks. Different heavy metals induce specific changes in miRNA expression profiles. For example, arsenic exposure has been linked to alterations in miRNAs that regulate genes involved in DNA repair, apoptosis, and cancer progression. Similarly, exposure to cadmium and lead has been associated with changes in miRNAs involved in oxidative stress and inflammation. These specific changes allow researchers to identify the type and level of exposure, providing a more targeted approach to monitoring and managing heavy metal toxicity. By studying the expression patterns of miRNAs, researchers can gain a deeper understanding of how heavy metals affect cellular processes like oxidative damage, apoptosis, and cellular repair mechanisms, thereby identifying potential therapeutic targets. Despite their potential, there are several challenges associated with using miRNAs as biomarkers for heavy metal exposure. One significant challenge is the need for standardization in miRNA detection methods. Although promising results have been reported in smaller studies, larger, population-based studies are required to confirm the reliability and robustness of miRNAs as diagnostic tools for heavy metal toxicity. Future research will likely focus on identifying miRNA panels that are specific to particular metals and that can be used for comprehensive environmental monitoring. Researchers are also exploring the use of miRNAs in combination with other biomarkers, such as proteins or metabolites, to create a more holistic approach to assessing environmental exposures. MicroRNAs hold great promise as biomarkers for detecting and monitoring heavy metal exposure. Their ability to reflect cellular responses to toxic metals, along with their sensitivity and ease of detection, makes them valuable tools for early diagnosis and intervention. As research in this area progresses, miRNAs could become a key component of routine environmental health monitoring, offering new insights into the mechanisms of metal toxicity and paving the way for more effective public health strategies to mitigate the risks associated with heavy metal exposure.
