Transcriptomic biomarker analysis of micro- and nanoplastic induced cardiovascular toxicity reveals perturbations in mitochondrial and ribosomal networks
AI summary Read the abstract
Scientists analyzed gene activity data to see how tiny plastic particles (microplastics and nanoplastics) affect human cells, and found they disrupt genes involved in energy production and protein-building—changes that overlap with patterns seen in heart disease. While this study looked at cell data rather than actual heart damage, it adds to growing evidence that plastic pollution may stress the body in ways that could contribute to cardiovascular problems, making it a good reason to reduce plastic exposure where possible while researchers investigate further.
ABSTRACT Environmental pollutants are increasingly recognized as major threats to human health worldwide with micro and nanoplastics (MNPs) outstanding on top, yet their contribution to cardiovascular disease (CVD) at the molecular level remains underexplored. In our study, we conducted an integrative bioinformatics analysis of human transcriptomic datasets to investigate the transcriptional alterations induced by MNP exposure. Differentially expressed genes revealed pervasive perturbations in pathways central to cardiovascular pathology, including oxidative stress, lipid metabolism, immune activation and mitochondrial functions. Protein-protein interaction networks and hub gene analysis identified mitochondrial genes such as MT-ND1 and COX5A , which were upregulated and linked to a potential mitochondrial stress signature requiring functional validation due to enhanced oxidative phosphorylation. On the other hand, ribosomal genes such as RPL5 were downregulated, suggesting impaired translational capacity and protein synthesis. This dual molecular mark, mitochondrial transcriptional regulation alongside ribosomal suppression highlights a coordinated cellular stress mechanism that could contribute to inflammation, remodeling, and energy imbalance in cardiovascular tissues. By mapping these signatures against cardiovascular associated gene sets, we demonstrated the MNP exposure converges molecular pathways already implicated in atherogenesis, cardiac remodeling, and vascular dysfunction. Importantly, transcription factor enrichment suggested upstream regulation by stress responsive factors, providing new insights into how plastic exposure may alter cellular homeostasis. Collectively, this work presents an integrative analysis linking transcriptomic signatures of human MNP exposed lung and intestinal cell models to curated cardiovascular disease gene sets. Our findings propose candidate hub genes and regulatory pathways for experimental validation and underscores the urgency of considering environmental plastic pollution into cardiovascular risk assessment, prevention, and therapeutic development.

Scientists found that tiny plastic particles called nanoplastics can damage heart cells by disrupting their powerhouses (mitochondria) and reducing their ability to produce energy. When researchers exposed human heart cells and mice to these nanoplastics, they observed weakened heart function and signs of early heart damage. This research suggests that the growing amount of microscopic plastic pollution in our environment could pose previously unknown risks to heart health.

Tiny plastic particles called micro- and nanoplastics are getting into our bodies through food, air, and skin contact, and researchers have found them building up in people's hearts and blood vessels. This review of existing studies shows these plastic bits may contribute to heart disease by causing inflammation and damaging cells in the cardiovascular system. While more research is needed, this suggests that plastic pollution isn't just an environmental problem—it could be directly harming our heart health.

Tiny plastic particles from everyday pollution, called microplastics and nanoplastics, may be quietly harming your heart, according to this review that pulls together over a decade of research. Scientists found these particles can disrupt cholesterol processing, make blood more likely to clot, and directly damage heart cells, partly by causing inflammation and stress inside cells. While more research is needed to fully understand the risks, this adds plastic pollution to the growing list of factors, alongside diet and exercise, that may affect your cardiovascular health.
