Gut microbiota health closely associates with PCB153-derived risk of host diseases
2020
Abstract Although the production and use of PCB153 have been banned globally, PCB153 pollution remains because of its persistence and long half-life in the environment. There is ongoing evidence that exposure to PCB153 may influence gut microbiota health and increase the risk of host health. It is needed to illuminate whether there are associations between gut microbiota dysregulation and PCB153-induced host diseases. Importantly, it is urgently needed to find specific strains as biomarkers to monitor PCB153 pollution and associated disorders. The work aims to investigate the change of gut microbiota composition, structure and diversity and various host physiological indexes, to ravel the chain causality of PCB153, gut microbiota health and host health, and to find potential gut microbiota markers for PCB153 pollution. Here, adult female mice were administrated with PCB153. Obtained results indicated that PCB153 led to gut microbiota health deterioration. PCB153 exposure also induced obesity, hepatic lipid accumulation, abdominal adipose tissue depots and dyslipidemia in mice. Furthermore, specific gut microbiota significantly correlated with the host health indexes. This work provides support for the relationship between gut microbiota aberrance derived from PCB153 and risk of host health, and offers some indications of possible indicative functions of gut microbiota on PCB153 pollution.
