Randomized trial investigates the impact of PM2.5 on endometriosis progression, suggesting links to estrogen receptors.

This research aims to explore how PM2.5 exposure affects the progression of endometriosis and the underlying molecular mechanisms.
Used in vitro models with EM cells exposed to PM2.5 at 200 µg/ml for analysis of proliferation and gene expression.
Developed an endometriosis-induced mouse model to assess the effects of PM2.5 at low (10 mg/kg/day) and high (20 mg/kg/day) doses over 4 weeks.
Evaluated changes in gene expression related to apoptosis, proliferation, and inflammation following PM exposure.
PM exposure significantly enlarged endometriotic lesions compared to controls.
The estrogen receptor ratio decreased from 1.03 in controls to 0.57 (P=0.02) in low-dose and 0.46 (P=0.03) in high-dose groups.
Upregulated gene expression in endometriotic lesions included markers for proliferation (p-ERK), inflammation (IL-6, IL-1β), and migration (MMP-2, MMP-9).

Jung et al. (2025) studied this question.
