Raises a question worth testing. It does not answer one.
This is a computational study using network toxicology and molecular docking to predict how 21 phthalate esters and polycyclic aromatic hydrocarbons might mechanistically contribute to gestational hypertension, gestational diabetes mellitus, and gestational obesity. The analysis identified shared target genes and modeled binding interactions between selected PAHs and hub proteins, but provides no experimental or human clinical evidence of causal effect.
Computational network toxicology and molecular docking analysis. Computational targets and pathways relevant to gestational hypertension, gestational diabetes mellitus, and gestational obesity; no human subjects enrolled.. Intervention: 21 phthalate esters and polycyclic aromatic hydrocarbons (computational analysis of interactions with identified hub proteins).
Identified 149 overlapping targets for gestational hypertension, 214 for GDM, and 149 for gestational obesity Central hub genes TNF, CASP3, BCL2, and ESR1 enriched in MAPK, calcium signaling, and insulin resistance pathways Docking simulations showed strong binding affinities: benzo(b)fluoranthene to TNF (–8.5 kcal/mol), benzo(k)fluoranthene to BCL2 (–9.4 kcal/mol), and benzo(ghi)perylene to CASP3 (–6.8 kcal/mol)

This work identifies potential molecular mechanisms warranting experimental and epidemiological investigation. Clinicians should recognize this as hypothesis-generating rather than confirmatory evidence and await validation studies before considering changes to clinical practice or counseling regarding environmental pollutant exposure in pregnancy.

Phthalates (PAEs) and polycyclic aromatic hydrocarbons (PAHs) are environmental pollutants linked to metabolic disorders, yet their role in gestational hypertension, gestational diabetes mellitus (GDM), and gestational obesity remians unclear. This study employed network toxicology and molecular docking to investigate the potential mechanisms by which 21 PAEs and PAHs influence these gestational conditions. We first predicted pollutant target genes using TargetNet and SwissTargetPrediction and cross-referenced them with disease-related genes from established databases to identify overlapping targets. Protein–protein interaction (PPI) networks were then constructed using the STRING database, followed by GO/KEGG enrichment analyses to determine the biological functions and pathways of these targets. Finally, molecular docking was performed to validate the interactions between key pollutants and identified hub proteins. Our analysis identified 149, 214, and 149 overlapping targets for gestational hypertension, GDM, and gestational obesity, respectively. The PPI networks highlighted central hub genes, including TNF, CASP3, BCL2, and ESR1, which were significantly enriched in pathways crucial for metabolism and cellular response, such as MAPK, calcium signaling, and insulin resistance. Docking simulations revealed strong binding affinities of several PAHs—notably benzo(b)fluoranthene, benzo(k)fluoranthene, and benzo(ghi)perylene—to the hub proteins TNF (–8.5 kcal/mol), BCL2 (–9.4 kcal/mol), and CASP3 (–6.8 kcal/mol). These findings suggest that PAEs and PAHs may contribute to gestational metabolic disorders through potential interactions with key regulators of inflammation, apoptosis, and metabolism. This research underscores the need for further investigation into the impact of environmental pollutants on maternal health during pregnancy.
