OBJECTIVE Aquaporin (AQP) 1 and AQP 4 are expressed in human heart and several studies have been focused on these two aquaporins. For this purpose, the present study is aimed to research the effects of aging on AQP 1 and AQP 4 in heart tissue. METHODS In this study, 14 Balb/C type white mice were used. Animals were divided into two equal groups. Group I consisted of 2-month-old young animals ...
Background and Objectives: The brain damage caused by trauma is the most common cause of death. The neuroprotection effects of estrogen and progesterone have been reported in numerous studies. In the present study, the role of different doses of sex steroids has been investigated on the aquaporin 4 protein concentration changes in brain tissue of ovariectomized (OVX) rats after traumatic brain ...
We previously showed that aquaresis induced by the peripherally acting nociceptin/orphanin FQ receptor agonist ZP120 is associated with a decreased protein level of aquaporin-2 (AQP2) in whole-kidney homogenates. We now examined the effects of Ac-RYYRWKKKKKKK-NH(2) (ZP120) (1 nmol/kg/min i.v. for 4 h) on renal regional expression (cortex/outer stripe of outer medulla, inner stripe of outer medu...
To the Editor: In their review article on water balance, Knepper et al. (April 2 issue)1 discuss water channels (aquaporins) in renal tubular cells. They omit mention of the critical role played by aquaporin-1 in microvascular endothelia. In the renal microvasculature, endothelial aquaporin-1 mediates the osmotic water efflux across descending vasa recta and is required for regulation of medull...
INTRODUCTION Gene expression profiling was performed via DNA microarrays in leukocytes from critically ill trauma patients nonseptic upon admission to the ICU, who subsequently developed either sepsis (n = 2) or severe sepsis and acute respiratory distress syndrome (n = 3). By comparing our results with published expression profiling studies in animal models of sepsis and lung injury, we found ...
Aquaporin facilitates the osmotic water transport across biomembranes and is involved in the transcellular and intracellular water flow in plants. We immunochemically quantified the aquaporin level in leaf plasma membranes (PM) and tonoplast of Graptopetalum paraguayense, a Crassulacean acid metabolism (CAM) plant. The aquaporin content in the Graptopetalum tonoplast was approximately 1% of tha...
