Age-related changes in renal AQP3 and AQP4 expression in Sprague Dawley rats

X. H. Jing, Liu, J., Hou, W. Y., Gao, Y., Jing, X. H., Liu, J., Hou, W. Y., and Gao, Y., Age-related changes in renal AQP3 and AQP4 expression in Sprague Dawley rats, vol. 15, p. -, 2016.

Aquaporin (AQP) 3 and AQP4 are important in urine concentrating mechanisms and in other physiological functions such as brain water balance, cell migration, cell proliferation, fat metabolism, and epidermal hydration. The results of studies investigating AQP3 and AQP4 expression in the kidneys are inconsistent, and systematic research is rare. This study aimed to obtain a better understanding of the changes in renal AQP3 and AQP4 mRNA expression that take place with age.

Effect of hyperphosphatemia on gene expression of the Na-Pi cotransporter in rats

We investigated the effect of high phosphorus content on the sodium-phosphate cotransporter (NaPi-IIa and NaPi-IIl). Forty-eight Sprague-Dawley rats were divided into 3 groups: high-phosphorus group (HP) with fructose diphosphate sodium injection; self-manufactured low-phosphorus diet group (LP); and normal diet group (NP). At the 1st, 2nd, 4th, and 6th weeks, 4 rats from each group were sacrificed for detecting serum levels of calcium, phosphorus, and intact parathyroid hormone.
