Sex-specific effects of aged polystyrene microplastics on hepatic AMPK pathway activation and lipid droplet accumulation in MAFLD mice.

Microplastics (MPs) are environmental pollutants attracting widespread attention due to their environmental omnipresence and potential health effects. MPs undergo ageing in the environment and our previous research found that aged Polystyrene microplastics (PS-MPs) affected lipid metabolism in healthy female mice, but not males. In this study, we examined the effects of aged PS-MP exposure on lipid metabolism in mice with Metabolic Associated Fatty Liver Disease (MAFLD).

Plastic-related endocrine disrupting chemicals significantly related to the increased risk of estrogen-dependent diseases in women.

Objective: To evaluate the association between exposure to plastic-related endocrine-disrupting chemicals (EDCs), specifically Bisphenol A (BPA), Phthalates, Cadmium, and Lead, and the risk of estrogen-dependent diseases (EDDs) such as polycystic ovary syndrome (PCOS), endometriosis, or endometrial cancer by conducting a meta-analysis of relevant studies.

Methods: PubMed, Web of Science, and Cochrane Library databases were used for literature retrieval of articles published until the 21st of April 2023. Literature that evaluated the association between BPA, phthalates, cadmium, and/or lead exposure and the risk of PCOS, endometriosis, or endometrial cancer development or exacerbation were included in our analysis.
