Effects of cAMP and CFTR modulation on apical fluid pH in human airway Calu‐3 cells
Abstract The airway epithelium serves as the first line of defense against inhaled insults present in the external environment by acting as a physical barrier and through host defense mechanisms. Proper maintenance of these host defense mechanisms relies on the regulation of airway surface liquid (ASL) composition and properties, a process that is ...

9‐phenanthrol inhibits TMEM16A channels
Intravascular pressure stimulates several smooth muscle cell TRP channels, including TRPM4, leading to membrane depolarization and vasoconstriction (the myogenic response). Previous studies using 9‐phenanthrol (9‐phen), a TRPM4 channel inhibitor, suggest that TRPM4 is essential for pressure‐induced depolarization and constriction ...

Structural and Biophysical Analysis of the CLCA1 VWA Domain Suggests Mode of TMEM16A Engagement
Summary: The secreted protein calcium-activated chloride channel regulator 1 (CLCA1) utilizes a von Willebrand factor type A (VWA) domain to bind to and potentiate the calcium-activated chloride channel TMEM16A.

Primary bile acids synthesized in the liver are transformed by gut microbes into secondary bile acids that engage receptors such as FXR and TGR5, thereby modulating immune function and metabolic homeostasis. Dysregulation of these signaling pathways contributes to MASH, NAFLD, IBD, and neurodegenerative disorders, underscoring their relevance as ...

Piezo1 in intestinal smooth muscle cells: Emerging perspectives
Abstract figure legend Loss of Piezo1 in SMCs results in delayed gut transit, impaired small bowel contractility, and tissue alterations. But more critically, Piezo1 is shown to be intracellularly localized, highlighting important implications given the phenotype. Adapted from Bautista, G.M. et al.

Mechanisms of antidiarrhoeal effects by diosmectite in human intestinal cells [PDF]
Rotavirus (RV) induces diarrhoea through a sequence of enterotoxic and cytotoxic effects. The former are NSP4-dependent, induce calcium-dependent chloride secretion and involve oxidative stress.

CRISPR-Mediated VHL Knockout Generates an Improved Model for Metastatic Renal Cell Carcinoma. [PDF]
Metastatic renal cell carcinoma (mRCC) is nearly incurable and accounts for most of the mortality associated with RCC. Von Hippel Lindau (VHL) is a tumour suppressor that is lost in the majority of clear cell RCC (ccRCC) cases.

Background and purpose The action potential underpinning calcium delivery for contraction in human uterine smooth muscle (myometrium) consists of an initial spike(s) followed by a prolonged plateau of depolarization to ⁓ −25 mV. The plateau duration establishes contraction duration, especially important in labour.

Upregulation of TMEM16A Protein in Bronchial Epithelial Cells by Bacterial Pyocyanin.
Induction of mucus hypersecretion in the airway epithelium by Th2 cytokines is associated with the expression of TMEM16A, a Ca2+-activated Cl- channel. We asked whether exposure of airway epithelial cells to bacterial components, a condition that mimics ...
