慢性氟中毒大鼠腎組織Beclin1、LC3、p62、Bcl-2表達變化及意義
[Abstract]:Objective to observe the expression of autophagy associated factor microtubule-associated protein 1 (Beclin1), microtubule-associated protein 1 light chain 3 (LC3) p62 and anti-apoptotic factor B cell lymphoma gene / leukemia gene 2 (Bcl-2) in chronic fluorosis rats. To investigate the significance of autophagy and apoptosis in renal injury caused by chronic fluorosis. Methods 36 healthy SD rats were randomly divided into control group, low fluorine group and high fluorine group with 12 rats in each group. The control group drank tap water containing sodium fluoride for less than 1 mg/L, while the high fluorine group drank the tap water containing sodium fluoride for 550 mg/L, and the model of fluorosis was established after 6 months of intervention. At the end of intervention, the rats were sacrificed by femoral artery bloodletting, the renal tissues were taken, the pathological changes of renal tissue were observed under light microscope, the expression of Bcl-2 protein and mRNA in renal tissue were detected by immunohistochemical method and RT-PCR method. Results the results of HE showed that the renal glomeruli and renal tubules in the control group had no obvious changes, and the renal tubular epithelial cells were arranged neatly. In low fluoride group and high fluoride group, renal tubular epithelial cells were edema and lumen stenosis, especially in high fluorine group. Compared with the control group, the expression of Beclin1 + LC3 protein and mRNA in renal tissue of low fluorine group and high fluorine group were significantly higher than those of control group (P < 0. 05). The expression of Beclin1 + LC3 protein and mRNA in high fluorine group was higher than that in low fluorine group. The expression of Bcl-2 protein and mRNA were lower in high fluorine group than in low fluoride group (P 0.05). Conclusion autophagy and apoptosis of renal tissue were activated after chronic fluorosis in rats, and the degree of activation was related to the degree of fluorosis, which may be involved in the pathogenesis of renal injury caused by chronic fluorosis.
