  • Title: Effect of exercise on gene expression of atrial natriuretic peptide receptor of kidney.
    Author: Shanshan P, Yan Z, Aiyun L, Chen P.
    Journal: Life Sci; 2005 Mar 11; 76(17):1921-8. PubMed ID: 15707875.
    Abstract:
    To study the effect of exercise on gene expression of natriuretic peptide receptors (NPRs) in the kidney, with in situ hybridization and the computerized image analysis, we investigated the alterations of gene expression of NPRs on the animal model of exercise training of different intensity. We found that after exercise training of different intensity, renal NPR-A mRNA and NPR-C mRNA expression showed different changes, the expression of NPR-A mRNA upregulated and NPR-C mRNA downregulated in the kidney. With the increase exercise intensity, change in NPR-A mRNA expression was insignificant, but downregulation in NPR-C mRNA expression was more significant. The result suggested that the effect of exercise on renal NPRs mRNA expression was mainly on the modulation level of NPR-C mRNA, it could reduce the clearance rate of ANP, increase the level of ANP, and enhance the biological effect of ANP on the kidney and regulative action of kidney in exercise.
