Abstract

Background: Per- and polyfluoroalkyl substances (PFAS) are human-made chemicals that accumulate in the human body and the environment over time. Humans are primarily exposed to PFAS through drinking water, food, consumer products, and dust. These exposures can have many adverse health effects, including cardiovascular diseases (CVDs) and factors contributing to CVDs. This study identified the molecular mechanisms of CVDs caused by PFAS.

Methods: For this purpose, various computational tools, such as the Comparative Toxicogenomic Database, ShinyGO, ChEA3, MIENTURNET, GeneMANIA, STRING, and Cytoscape, were used to conduct in silico analyses.

Results: The results showed that 10 genes were common between PFAS and CVDs, and among these common genes, the PPAR signaling pathway, fatty acid metabolic processes, and lipid binding were the most significantly associated gene ontology terms. Among the top 10 transcription factors (TFs) related to these common genes, peroxisome proliferator-activated receptor gamma and androgen receptor were the most prominent. Additionally, hsa-miR-130b-3p, hsa-miR-130a-3p, and hsa-miR-129-5p were featured microRNAs involved in PFAS-induced CVDs. Finally, PPARA and PPARG were identified as core genes involved in PFAS-induced CVDs.

Conclusion: These findings may contribute to a better understanding of the molecular mechanisms and reveal new potential targets in PFAS-induced CVDs.

Keywords: PPAR alpha; PPAR gamma; Per- and polyfluoroalkyl substances; cardiovascular toxicity.
