Recent scientific evidence reveals that BPA and diabetic foot ulcers (DFU) have a complex and harmful relationship. Bisphenol A (BPA), a common environmental chemical, significantly impairs the immune microenvironment necessary for chronic wound healing. This disruption complicates the management of diabetic complications, especially in regions with high plastic exposure. Consequently, understanding these molecular mechanisms is crucial for improving patient outcomes.
Through multi-omics analysis, researchers identified 51 common targets shared between BPA exposure and DFU development. These targets primarily regulate inflammatory responses and extracellular matrix remodeling. Furthermore, the study highlights three core proteins: BCL2, EGFR, and MMP9. These proteins control vital processes in B cells, fibroblasts, and macrophages. Therefore, when BPA binds to these targets, it inhibits the cellular regeneration essential for ulcer closure.
Specifically, the study points to the disruption of the PI3K-Akt and MAPK signaling pathways. Molecular docking confirms that BPA exhibits strong binding activity with key repair proteins. For instance, BCL2 expression occurs mainly in B cells, while fibroblasts primarily express EGFR. Moreover, MMP9 specifically functions within macrophages. When BPA interferes with these cells, the wound healing process stalls in a persistent inflammatory state. In addition, this chemical exposure reduces the effectiveness of angiogenesis, further delaying tissue repair.
Consequently, clinicians should recognize that environmental factors may exacerbate refractory ulcers. Managing plastic exposure could potentially support better clinical results in diabetic wound care. In addition, future therapeutic strategies might involve screening for antagonists to block these harmful interactions. Therefore, environmental history is becoming an essential part of chronic wound assessment.
BPA disrupts the immune microenvironment by binding to core proteins like MMP9 and EGFR. This interaction stalls inflammation and prevents the structural remodeling required for skin regeneration.
While clinical trials are pending, the study suggests that BPA exposure significantly worsens wound healing. Therefore, reducing exposure to BPA-containing plastics might theoretically aid the natural repair process and improve therapeutic efficacy.
