Renal aquaporins. Aquaporins (AQPs) are a newly recognized family of transmembrane proteins that function as molecular water channels. At least four aquaporins are expressed in the kidney where they mediate rapid water transport across water-permeabl

Permeability criteria for effective function of passive countercurrent multiplier

Autor: C. L. Chou, M. A. Knepper, Harold E. Layton

Publikováno v: American Journal of Physiology-Renal Physiology. 270:F9-F20

The urine concentrating effect of the mammalian renal inner medulla has been attributed to countercurrent multiplication of a transepithelial osmotic difference arising from passive absorption of NaCl from thin ascending limbs of long loops of Henle.

Studies of renal aquaporin-2 expression during renal escape from vasopressin-induced antidiuresis

Autor: J G, Verbalis, T, Murase, C A, Ecelbarger, S, Nielsen, M A, Knepper

Publikováno v: Advances in experimental medicine and biology. 449

In animal models of the syndrome of inappropriate antidiuresis (SIADH), sustained administration of vasopressin and water results in free-water retention and progressive hyponatremia for several days, which is then followed by escape from the vasopre

Disordered water channel expression and distribution in acquired nephrogenic diabetes insipidus

Autor: D, Marples, J, Frøkiaer, M A, Knepper, S, Nielsen

Publikováno v: Proceedings of the Association of American Physicians. 110(5)

A series of recent studies have demonstrated that expression of aquaporin-2 (AQP2), the vasopressin-regulated water channel of the kidney collecting duct, is greatly reduced in acquired forms of nephrogenic diabetes insipidus (NDI). In some forms of

Long-term regulation of inner medullary collecting duct urea transport in rat

Autor: A Kato, M A Knepper, Jeff M. Sands, M Naruse

Publikováno v: Journal of the American Society of Nephrology : JASN. 9(5)

Facilitated urea transport is regulated acutely by arginine vasopressin (AVP) and hyperosmolality in rat terminal inner medullary collecting duct (IMCD). This study tested whether chronic diuresis or antidiuresis regulates facilitated urea transport.

Frøkiaer, J, Christensen, B M, Marples, D, Djurhuus, J C, Jensen, U B, Knepper, M A & Nielsen, S 1997, ' Downregulation of aquaporin-2 parallels changes in renal water excretion in unilateral ureteral obstruction ', American Journal of Physiology (Consolidated), vol. 273, no. 2 Pt 2, pp. F213-23 .
Scopus-Elsevier

In bilateral ureteral obstruction, both aquaporin-2 (AQP2) levels and urinary concentrating capacity are markedly reduced. However, the mechanisms involved in AQP2 downregulation are unknown. In rats with unilateral ureteral obstruction (UUO) the rel

Segmental localization of urea transporter mRNAs in rat kidney

Autor: Matthias A. Hediger, M. A. Knepper, Craig P. Smith, Chairat Shayakul, S. R. DiGiovanni

Publikováno v: The American journal of physiology. 272(5 Pt 2)

Renal epithelia express at least two distinct urea transporter mRNAs, termed UT1 and UT2, that are derived from a single UT gene by alternative splicing. Previous immunolocalization studies using a polyclonal antibody that does not distinguish betwee

Bilateral ureteral obstruction downregulates expression of vasopressin-sensitive AQP-2 water channel in rat kidney

Autor: M A Knepper, Søren Nielsen, D Marples, Jørgen Frøkiær

Publikováno v: The American journal of physiology. 270(4 Pt 2)

Polyuria after release of bilateral ureteral obstruction (BUO) is frequently seen in patients with urological disorders. In this study, we examined the effect of BUO and release of BUO on the expression of the vasopressin-regulated water channel aqua
