Exploring aryl hydrocarbon receptor (AhR) as a target for Bisphenol-A (BPA)-induced pancreatic islet toxicity and impaired glucose homeostasis: Protective efficacy of ethanol extract of Centella asiatica.

The estrogenic impact of Bisphenol-A (BPA), a widely recognized endocrine disruptor, causes disruption of pancreatic β-cell function through estrogen receptors (ERs). While BPA's binding affinity for ERs is significantly lower than that of its natural counterpart, estrogen, recent observations of BPA's affinity for aryl hydrocarbon receptor (AhR) in specific cellular contexts have sparked a specific question: does AhR play a role in BPA's toxicological effects within the endocrine pancreas? To explore this question, we investigated BPA's (10 and 100 μg/ kg body weight/day for 21 days) potential to activate AhR within pancreatic islets and assessed the protective role of ethanol extract of Centella asiatica (CA) (200 and 400 mg/kg body weight/day for 21 days) against BPA-mediated toxicity in mouse model. Our results indicate that BPA effectively triggers the activation of AhR and modulates its target genes within pancreatic islets.

Molecular dissection of cellular response of pancreatic islet cells to Bisphenol-A (BPA): A comprehensive review.

Bisphenol A (BPA) is an endocrine disrupting chemical which poses great concern because of its high proportionate industrial production, omnipresent human exposure and budding toxic consequences in human. A plethora of previous studies has connected BPA to a variety of negative health outcomes and diabetes mellitus is among the first bencher. However, there is disagreement over the degree of toxic effects generated by low and high doses of BPA and critical period of exposure.
