ABSTRACT
Objective The calcium oxalate stone is the most common type of the kidney stones.By building the rat renal calcium oxalate stone model, preliminary study the function of CaSR-Claudin14 regulating pathways on renal calcium oxalate stone for-mation model in rats. Methods 30 Male S-D rats were randomly divided into control group (n=15) and model group (n=15). Adult male S-D rats were given ethylene glycol and ammonium chloride to induce urolithiasis.Application of full automatic biochemical analyzer to test rat renal function and the changes of urine biochemical index.Immunohistochemistry was used to detect the expression of CaSR protein;RT-PCR was used to detect the Claudin-14 mRNA expression;Western Blotting was used to detect the expression of CaSR and Claudin-14 protein respectively. Results By observing model group has large stones crystallization under light microsco-py;model group rats 24 h urine calcium are significantly higher than control group([9.66 ±1.10]mmol vs [3.26 ±0.60]mmol, P0.05 ) .Expression of Claudin-14 mRNA in the model group is significantly higher than normal control group([0.150 ± 0.004] vs [0.047 ±0.008], P<0.01); Expression of Claudin-14 protein in the model group is significantly higher than normal control group([1.526 ±0.089] vs 0, P<0.01).Expression of CaSR protein in the model group is significantly higher than normal control group([6.697 ±0.051] vs [5.016 ±0.053], P<0.05). Conclusion CaSR can raise the expression of Claudin-14, increase re-nal tubular urinary calcium excretion to promote renal calcium oxalate stone formation.
