A multiscale model of the regulation of aquaporin 2 recycling [PDF]
npj Systems Biology and Applications, 2022 The response of cells to their environment is driven by a variety of proteins and messenger molecules. In eukaryotes, their distribution and location in the cell are regulated by the vesicular transport system.

α-Actinin 4 Links Vasopressin Short-Term and Long-Term Regulation of Aquaporin-2 in Kidney Collecting Duct Cells [PDF]
Frontiers in Physiology, 2021 Water permeability of the kidney collecting ducts is regulated by the peptide hormone vasopressin. Between minutes and hours (short-term), vasopressin induces trafficking of the water channel protein aquaporin-2 to the apical plasma membrane of the ...

Neural Regulation of Urothelial Water Transport: Pelvic Nerve Stimulation Induces Aquaporin-2 and Vasopressin V1a Receptor Translocation in the Rat Urinary Bladder [PDF]
International Neurourology JournalPurpose Aquaporin-2 (AQP2) and vasopressin V1a receptor (AVP-V1a) are membrane proteins involved in water transport regulation in renal and extrarenal tissues. Their presence in the urinary bladder suggests a role in local water handling.

Localization and trafficking of aquaporin 2 in the kidney [PDF]
Histochemistry and Cell Biology, 2008 Aquaporins (AQPs) are membrane proteins serving in the transfer of water and small solutes across cellular membranes. AQPs play a variety of roles in the body such as urine formation, prevention from dehydration in covering epithelia, water handling in the blood-brain barrier, secretion, conditioning of the sensory system, cell motility and metastasis,

miR-34b-5p promotes renal cell inflammation and apoptosis by inhibiting aquaporin-2 in sepsis-induced acute kidney injury [PDF]
Renal Failure, 2021 Objective This study was designed to uncover the mechanism of miR-34b-5p-mediated aquaporin-2 (AQP2) in sepsis-induced injury using human renal tubular epithelial cells (HK-2). Methods Serum levels of miR-34b-5p, TNF-α, IL-1β, IL-6, serum creatinine (SCr)

Molecular Characterization of an Aquaporin−2 Mutation Causing Nephrogenic Diabetes Insipidus [PDF]
Frontiers in Endocrinology, 2021 The aquaporin 2 (AQP2) plays a critical role in water reabsorption to maintain water homeostasis. AQP2 mutation leads to nephrogenic diabetes insipidus (NDI), characterized by polyuria, polydipsia, and hypernatremia.

Diabetes insipidus in mice with a mutation in aquaporin-2. [PDF]
PLoS Genetics, 2005 Congenital nephrogenic diabetes insipidus (NDI) is a disease characterized by failure of the kidney to concentrate urine in response to vasopressin. Human kindreds with nephrogenic diabetes insipidus have been found to harbor mutations in the vasopressin

Characterization of three vasopressin receptor 2 variants: an apparent polymorphism (V266A) and two loss-of-function mutations (R181C and M311V). [PDF]
, 2013 Arginine vasopressin (AVP) is released from the posterior pituitary and controls water homeostasis. AVP binding to vasopressin V2 receptors (V2Rs) located on kidney collecting duct epithelial cells triggers activation of Gs proteins, leading to increased

Reduced urine volume and changed renal sphingolipid metabolism in P2ry14-deficient mice
Frontiers in Cell and Developmental Biology, 2023 The UDP-glucose receptor P2RY14, a rhodopsin-like G protein-coupled receptor (GPCR), was previously described as receptor expressed in A-intercalated cells of the mouse kidney.
