Sensory Functions for Degenerin/Epithelial Sodium Channels (DEG/ENaC) [PDF]

, 2011
All animals use a sophisticated array of receptor proteins to sense their external and internal environments. Major advances have been made in recent years in understanding the molecular and genetic bases for sensory transduction in diverse modalities, indicating that both metabotropic and ionotropic pathways are important in sensory functions.

The δ-Subunit of the Epithelial Sodium Channel (ENaC) Enhances Channel Activity and Alters Proteolytic ENaC Activation [PDF]

Journal of Biological Chemistry, 2009
The epithelial sodium channel (ENaC) is probably a heterotrimer with three well characterized subunits (alphabetagamma). In humans an additional delta-subunit (delta-hENaC) exists but little is known about its function. Using the Xenopus laevis oocyte expression system, we compared the functional properties of alphabetagamma- and deltabetagamma-hENaC ...

Molecular modeling of mechanosensory ion channel structural and functional features.

PLoS ONE, 2010
The DEG/ENaC (Degenerin/Epithelial Sodium Channel) protein family comprises related ion channel subunits from all metazoans, including humans. Members of this protein family play roles in several important biological processes such as transduction of ...

SPX-101 is stable in and retains function after exposure to cystic fibrosis sputum [PDF]

, 2019
Background: In healthy lungs, epithelial sodium channel (ENaC) is regulated by short, palate, lung, and nasal clone 1 (SPLUNC1). In cystic fibrosis (CF), ENaC is hyperactivated in part due to a loss of SPLUNC1 function.

Blood pressure effects of SGLT2 inhibitors and GLP‐1 receptor agonists: Mechanisms, trial evidence and Real‐world data

British Journal of Clinical Pharmacology, EarlyView.
SGLT2 inhibitors and GLP‐1 receptor agonists modestly lower blood pressure across diverse patient populations, including those without diabetes. These effects appear largely independent of glycaemic control and offer additive value in high‐risk patients with overlapping comorbidities.

Slow Transit Constipation: Pathophysiological Perspectives and Management Updates

Journal of Digestive Diseases, EarlyView.
Slow transit constipation (STC) is a complex neuromuscular disorder driven by interstitial cells of Cajal (ICCs) loss and enteric neuropathy. Diagnosis relies on objective transit testing while excluding pelvic floor dysfunction. Management follows a stepwise, phenotype‐driven approach, progressing from conventional laxatives to emerging targeted ...

Epithelial sodium channel (ENaC) is multi-ubiquitinated at the cell surface [PDF]

Biochemical Journal, 2007
The human ENaC (epithelial sodium channel), a complex of three subunits, provides the rate-limiting step for sodium uptake in the distal nephron, and therefore plays a key role in salt homoeostasis and in regulating blood pressure. The number of active sodium channel complexes present at the plasma membrane appears to be tightly controlled. In Liddle's

Claudins in the Renal Collecting Duct [PDF]

, 2019
The renal collecting duct fine-tunes urinary composition, and thereby, coordinates key physiological processes, such as volume/blood pressure regulation, electrolyte-free water reabsorption, and acid-base homeostasis.

Lung organoids as a human system for Mycobacteria infection modeling and drug testing

The FEBS Journal, EarlyView.
Mycobacterial infections, including tuberculosis (TB) and infections by nontuberculous mycobacteria (NTM), are still public health issues. In 2023, TB caused 1.25 million deaths, while NTM remain a clinical challenge for patients with cystic fibrosis (CF).
