The effects of endocrine disrupting chemicals on inflammation and oxidative stress in the prostate: an overview in different experimental models
摘要
Endocrine-disrupting chemicals (EDCs) are environmental pollutants capable of interfering with hormonal regulation and affecting the homeostasis of hormone-dependent organs such as the prostate. Increasing evidence links exposure to EDCs with prostate inflammation, oxidative stress, and carcinogenesis. These compounds, found in pesticides, plastics, surfactants, and heavy metals, act through diverse molecular pathways that disrupt endocrine, immune, and metabolic functions.
Purpose of ReviewFrom this perspective, the present review aims to synthesize current findings on the effects of EDCs on inflammation and oxidative stress in the prostate, highlighting experimental evidence from in vitro and in vivo models and discussing the main molecular mechanisms involved.
Recent FindingsRecent studies have strengthened the evidence that EDCs play a critical role in prostate pathophysiology by integrating inflammatory, oxidative, and epigenetic mechanisms. Advances in molecular biology have revealed that EDC exposure can modulate key signaling pathways, including NF-κB, TLR4, and TNF-α, leading to sustained inflammatory responses and disruption of redox homeostasis in prostatic cells.
ResultsExperimental studies demonstrate that EDCs such as bisphenol A, phthalates, nonylphenol, cadmium, arsenic, and vinclozolin induce inflammatory and oxidative alterations in prostate tissue. These effects include activation of pro-inflammatory signaling pathways, increased expression of cytokines, and upregulation of oxidative stress markers. Concurrently, these compounds impair antioxidant defense systems by modulating enzymes such as catalase, superoxide dismutase, and glutathione reductase. Chronic exposure promotes cellular proliferation, epithelial dysplasia, apoptotic resistance, and epigenetic modifications, contributing to prostate pathogenesis and tumorigenesis.
ConclusionEDCs exert profound effects on prostatic physiology by disrupting endocrine balance, promoting chronic inflammation, and inducing oxidative stress. The interplay between these processes establishes a microenvironment favorable to cellular transformation and tumor progression.
