Fluoride-Induced Alterations in the Pancreas of Mammals: A Meta-analysis

This review explores the diverse effects of fluoride on pancreatic function, encompassing both in vitro and in vivo studies. Fluoride exposure induces notable alterations at the cellular and molecular levels, affecting pancreatic morphology, histology, and enzymatic activity. In vitro studies demonstrate significant inhibition of pancreatic alpha-amylase activity and apoptosis in pancreatic beta cells. In vivo investigations reveal structural abnormalities in pancreatic cells, including mitochondrial damage, vacuolation, and nuclear damage. Moreover, fluoride exposure disrupts antioxidant enzyme activity, exacerbating oxidative stress and lipid peroxidation. Changes in digestive enzyme activity, such as the inhibition of pancreatic lipase and alpha-amylase, further contribute to pancreatic dysfunction. Additionally, alterations in hormone secretion, notably insulin levels and disturbed glucose homeostasis, highlight the complex effects of fluoride on the pancreatic endocrine system. These findings underscore fluoride-induced pancreatic toxicity and highlight the need for a comprehensive understanding and mitigation strategies to safeguard pancreatic health.
