Clock Genes Regulate Ca2+ Signaling and Mitochondrial Bioenergetics to Inhibit Sjögren Disease
Arthritis &Rheumatology, EarlyView.Objective Although Ca2+ signaling and metabolism have been identified as key determinants for the development of Sjögren disease (SjD), the intricate connection between them and salivary gland physiology remains poorly understood. Methods Fluorescence‐based Ca2+ imaging, RNA sequencing, and mitochondrial activity were used to investigate the effects of

Controlled aquaporin-2 expression in the hypertonic environment [PDF]
American Journal of Physiology-Cell Physiology, 2009 The corticomedullary osmolality gradient is the driving force for water reabsorption occurring in the kidney. In the collecting duct, this gradient allows luminal water to move across aquaporin (AQP) water channels, thereby increasing urine concentration. However, this same gradient exposes renal cells to great osmotic challenges.

Developmental Dynamics, EarlyView.Abstract The sea anemone, Nematostella vectensis, has been used as a model organism in developmental biology studies for many years. This estuarine species has the notable capacity to regenerate its full body plan from small pieces throughout life. Nematostella have been described as having a great degree of cellular plasticity.

Deficiency of Carbonic Anhydrase II Results in a Urinary Concentrating Defect
Frontiers in Physiology, 2018 Carbonic anhydrase II (CAII) is expressed along the nephron where it interacts with a number of transport proteins augmenting their activity. Aquaporin-1 (AQP1) interacts with CAII to increase water flux through the water channel. Both CAII and aquaporin-

Biomarkers of lung congestion and injury in acute heart failure
ESC Heart Failure, Volume 12, Issue 2, Page 781-789, April 2025.Abstract Acute heart failure (AHF) classification and management are primarily based on lung congestion and/or hypoperfusion. The quantification of the vascular and tissue lung damage is not standard practice though biomarkers of lung injury may play a relevant role in this context.

NEPHROGENIC DIABETES INSIPIDUS: THE CRUCIAL ROLE OF AQUAPORINS
Bioscience InsightsNephrogenic diabetes insipidus (NDI) is a disorder marked by the kidney's inability to concentrate urine despite normal or elevated levels of vasopressin, often due to impairments in aquaporin-2 (AQP2) expression or function.

Journal of Pharmacological Sciences, 2004 Targeted positioning of water channel aquaporin-2 (AQP2) strictly regulates body water homeostasis. Trafficking of AQP2 to the apical membrane is critical for the reabsorption of water in renal collecting ducts.
