Obesogens: How They Are Identified and Molecular Mechanisms Underlying Their Action
Researchers reviewed the science behind obesogens, a class of endocrine-disrupting chemicals that promote fat storage and metabolic dysfunction. These compounds act through multiple pathways including disrupting adipose tissue function, altering gut microbiome composition, and interfering with hormonal signaling, with effects that can persist across generations. The review highlights the need for improved chemical screening methods to identify obesogenic substances and protect public health.

Researchers exposed adult zebrafish to polyethylene and polyester microplastics at environmentally relevant concentrations and found significant disruptions to metabolic pathways and gut microbiome composition. Polyethylene primarily affected cell membrane compounds and inflammation-related metabolites, while polyester altered lipid metabolism and gut bacterial interactions. The study reveals that chronic microplastic exposure can cause subtle but meaningful shifts in fish metabolism and gut health, even at low concentrations.

The study suggests that early-life exposure to microplastics could have meaningful biological consequences by reshaping the gut environment of developing organisms.
Impacts of polystyrene nanoplastics on zebrafish gut microbiota and mechanistic insights
Zebrafish exposed to polystyrene nanoplastics showed significant changes in their gut bacteria, with beneficial species like Bifidobacterium declining and potentially harmful bacteria increasing. The nanoplastics physically entered intestinal tissues, causing visible damage to gut cells. This study is relevant to human health because our gut microbiome plays a key role in immunity and digestion, and similar disruption from nanoplastic exposure could contribute to digestive and immune problems.

Combined effects of high-fat diet and polystyrene microplastic exposure on microplastic bioaccumulation and lipid metabolism in zebrafish
Researchers studied how a high-fat diet combined with polystyrene microplastic exposure affects zebrafish, finding that obese fish accumulated significantly more microplastics in their tissues. The high-fat diet disrupted lipid metabolism and created conditions that increased microplastic retention in the body. This suggests that diet and body fat levels may influence how much microplastic accumulates in living organisms, with potential implications for human health.

Mechanism insights into the histopathological changes of polypropylene microplastics induced gut and liver in zebrafish
Researchers exposed zebrafish to polypropylene microplastics, one of the most common plastics found in rivers, and found damage to both the intestines and liver. The microplastics thinned the intestinal walls, disrupted gut bacteria communities, and altered liver gene activity related to fat processing and immune response. Since polypropylene is widely found in food packaging and the environment, these findings raise questions about similar effects in humans who ingest this type of microplastic.
