Molecular targets of developmental exposure to bisphenol A in diabesity: a focus on endoderm-derived organs

Area of Science:

• Endocrinology
• Toxicology
• Developmental Biology

Background:

• Bisphenol A (BPA) exposure during fetal development is linked to metabolic and endocrine disorders, particularly diabesity.
• BPA disrupts the function of key endoderm-derived organs, including pancreatic beta cells, adipocytes, and hepatocytes.
• The complexity of diabesity involves multiple organ systems, all potentially affected by BPA.

Purpose of the Study:

• To analyze the mechanisms of BPA toxicity in endoderm-derived organs following prenatal exposure.
• To synthesize epidemiological and in vivo data on BPA's effects on organs like the thyroid, pancreas, liver, gut, prostate, and lung.
• To highlight the risks of low-dose BPA exposure on human health and organ development.

Main Methods:

• Review and synthesis of existing epidemiological data.
• Compilation and analysis of in vivo experimental data on prenatal BPA exposure.
• Gathering and assessment of molecular data on BPA's effects at low doses.

Main Results:

• Prenatal BPA exposure is associated with disruptions in pancreatic beta cell, adipocyte, and hepatocyte functions.
• Low-dose BPA exposure demonstrates harmful molecular effects, indicating a potential risk to human health.
• Developmental BPA exposure can deregulate gene expression in endoderm-derived organs from early stages.

Conclusions:

• Prenatal exposure to BPA poses a risk to the development of endoderm-derived organs.
• BPA exposure can deregulate gene expression, contributing to diabesity.
• In vitro toxicogenomics approaches are proposed for identifying common BPA toxicity mechanisms in organs of similar developmental origin.
