Summary
This study reveals how Bisphenol A (BPA), an endocrine disruptor, may worsen atopic dermatitis (AD) by targeting key immune and inflammatory genes. Our computational approach identified six core targets, providing molecular insights into environmental factors contributing to AD.
Area of Science:
- Environmental Health
- Toxicology
- Dermatology
- Computational Biology
Background:
- Bisphenol A (BPA) is an endocrine disruptor found globally, linked to various health issues including immune system imbalance and chronic inflammation.
- Atopic dermatitis (AD) is a prevalent, rising inflammatory skin disorder with significant health and economic impacts.
- The precise molecular mechanisms linking BPA exposure to AD pathogenesis are not well understood.
Purpose of the Study:
- To elucidate the molecular pathways through which Bisphenol A (BPA) may promote or exacerbate atopic dermatitis (AD).
- To identify specific molecular targets of BPA involved in AD development using integrated computational methods.
Main Methods:
- Integrated network toxicology, transcriptomic data analysis, machine learning (LASSO, SVM), molecular docking, and molecular dynamics simulations.
- Collected and analyzed potential BPA targets and AD-associated genes from public databases (CTD, ChEMBL, SwissTargetPrediction, GeneCards, OMIM).
- Constructed a protein-protein interaction (PPI) network and identified hub genes, followed by machine learning to pinpoint core toxic targets.
Main Results:
- Identified six core toxic targets of BPA in AD: TIGIT, JAK3, IL22, S100A8, CCL2, and FCER1G.
- These targets are primarily involved in immune dysregulation and inflammatory cell infiltration, particularly within the PI3K-Akt, Th17 cell differentiation, and JAK-STAT signaling pathways.
- Molecular docking and dynamics simulations confirmed stable binding of BPA to these six targets.
Conclusions:
- This study provides crucial molecular evidence for the role of BPA in AD pathogenesis.
- The identified targets offer potential avenues for future research into BPA-induced AD and environment-gene interactions in inflammatory skin diseases.
- Findings support the need to understand environmental exposures in the context of complex diseases like atopic dermatitis.
