Bisphenol A exposure increased MMP2 and MMP9 expression in endometrial stromal cells and was associated with a higher risk of peritoneal endometriosis, suggesting a mechanism involving GPER and MAPK/ERK signaling.

This paper investigated whether bisphenol A (BPA) exposure is associated with endometrial (EM) disease risk and whether it alters matrix metalloproteinase activity relevant to invasion. It used a case–control study of 120 EM patients and 100 healthy women, measuring creatinine-adjusted urinary BPA concentrations and assessing serum MMP2 and MMP9 levels, and it complemented the epidemiologic data with in vitro experiments in human endometrial stromal cell lines (HESCs). Higher urinary BPA was positively associated with increased serum MMP2 and MMP9 and with greater risk of peritoneal EMs across quartiles, and BPA exposure increased MMP2 and MMP9 expression in a dose-dependent manner; these cellular effects were blocked by a GPER inhibitor or a MAPK/ERK inhibitor, implicating a GPER/MAPK-ERK pathway. The study explicitly limits generalization by noting that prior inconsistent findings were affected by inappropriate control selection, incorrect BPA detection methods, and lack of subtype-specific assessment, and it focuses mechanistic evidence on stromal cell lines. This paper is centrally about endometriosis—specifically, BPA exposure’s association with and mechanistic enhancement of peritoneal endometriosis via MMP2/MMP9 and GPER/MAPK-ERK signaling.

Abstract

Results of previous epidemiology studies on BPA exposure and endometriosis (EMs) risk were inconsistent, and were limited by inappropriate control selection, incorrect BPA detection method, and the generalization of different subtypes of EMs. Upregulated matrix metalloproteinase (MMP) 2 and MMP9 are involved in the development of EMs. We conducted a case-control study among 120 EMs patients and 100 healthy women to evaluate the relationships between BPA exposure and MMP2, MMP9 expressions, and the risk of EMs subtypes. Besides, we used human endometrial stromal cell lines (HESCs) to investigate the underlying mechanisms. Creatinine-adjusted urinary BPA concentrations were positively correlated with serum MMP2, MMP9 levels, and the risk of peritoneal EMs (third vs lowest quartile: OR 4.92, 95% CI 1.47, 16.50; fourth versus lowest quartile: OR 3.70, 95% CI 1.07, 12.74, Ptrend = 0.030). The risk of peritoneal EMs increased approximately tenfold when creatinine-adjusted urinary BPA concentration was 2 μg/g. In vitro study found that BPA exposure increased MMP2, MMP9 expressions in a dose-dependent manner. The effects of BPA on HESCs could be blocked by G protein-coupled estrogen receptor (GPER) inhibitor or mitogen-activated protein kinase/extracellular signal-regulated kinase (MAPK/ERK) inhibitor. This study provides evidence that BPA exposure promotes peritoneal EMs, and raises a concern about the potential toxicity of BPA on the female reproductive system.
