Abstrakt: Hepatotoxicity induced by excessive fluoride (F) exposure has been extensively studied in both humans and animals. Chronic fluorosis can result in liver apoptosis. Meanwhile, moderate exercise alleviates apoptosis caused by pathological factors. However, the effect of moderate exercise on F-induced liver apoptosis remains unclear. In this research, sixty-four three-week-old Institute of Cancer Research (ICR) mice, half male and half female, were randomly divided into four groups: control group (distilled water); exercise group (distilled water and treadmill exercise); F group [100 mg/L sodium fluoride (NaF)]; and exercise plus F group (100 mg/L NaF and treadmill exercise). The liver tissues of mice were taken at 3 months and 6 months, respectively. Hematoxylin-eosin (HE) staining and situ terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling (TUNEL) results showed that nuclear condensation and apoptotic hepatocytes occurred in the F group. However, this phenomenon could be reversed with the intervention of treadmill exercise. The results of QRT-PCR and western blot displayed NaF- induced apoptosis via tumor necrosis factor recpter 1 (TNFR1) signaling pathway, while treadmill exercise could restore the molecular changes caused by excessive NaF exposure.
