A quad‐cistronic fluorescent biosensor system for real‐time detection of subcellular Ca2+ signals

open access: yesBritish Journal of Pharmacology, EarlyView.
Background and Purpose The calcium ion (Ca2+) is a versatile cellular messenger regulating a variety of biological processes. Compounds modulating subcellular Ca2+ signals hold substantial pharmacological potential. Advances in fluorescent biosensors have revolutionised Ca2+ imaging.

Carbachol increases intracellular free calcium concentrations in human granulosa-lutein cells [PDF]

open access: yes, 1992
We investigated whether the stimulation of human granulosa-lutein cells with muscarinic and nicotinic receptor agonists can cause increases in intracellular free calcium (Ca2+), using Fura-2 microfluorimetry.

GCN2 in proteostasis: structural logic, signalling networks and disease

open access: yesThe FEBS Journal, EarlyView.
Threats to protein synthesis activate the kinase GCN2, initiating the integrated stress response (ISR). GCN2 is triggered by stalled ribosomes and uncharged tRNAs, which accumulate when amino acids are scarce. The ISR adjusts cellular physiology by promoting redox balance, protein quality control, and mitochondrial optimisation.

A Review of Nonsteroidal Anti‐Inflammatory Drugs for Food‐Producing Animals With a Focus on Potential Applications for Farmed Finfish

open access: yesJournal of Fish Diseases, EarlyView.
ABSTRACT In finfish aquaculture, there are several inflammatory diseases impacting productivity and animal welfare, however there are limited options available to veterinarians to treat inflammation and pain in fish. Nonsteroidal anti‐inflammatory drugs (NSAIDs) are widely used in terrestrial animals raised for human consumption to treat a range of ...

Photo-controlled permeation of spiropyran modified gramicidin A ion channel [PDF]

open access: yes, 2006
Thesis (M.S.) University of Alaska Fairbanks, 2006Biomimetic devices show great potential as being molecular sensors of biological species. Gramicidin A (gA) is a well studied ionophore that can be easily modified at the C-terminus to be incorporated ...

Ca2+-Stimulated Catecholamine Release from alpha-Toxin Permeabilized PC12 Cells [PDF]

open access: yes, 1987
Two possible cellular pathways of catecholamines from the chromaffin vesicles of PC 12 cells to the surrounding medium are explored in this study. The direct one circumventing the cytoplasm can be activated in a-toxin-permeabilized cells with micromolar ...

Metabolic stimulation improves bioenergetics and haematologic indices of circulating erythrocytes from sickle cell mice

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Metabolic stimulation improves bioenergetics, redox state, hydration and hematologic indices of circulating erythrocytes from sickle cell mice. Retained mitochondria in circulating RBCs from sickle mice are a source of RBC ATP as mitochondria function (ETC, electron transport chain) inhibitors [rotenone, a mitochondrial complex I

Role of Calcium Propionate and Monensin on Performance, Rumen Fermentation Patterns, and Ruminal Bacterial Populations in Growing Lambs

open access: yesVeterinary Sciences
The objective of this study was to determine the effects of dietary calcium propionate (CaPr) and monensin (MON) on lamb growth performance, ruminal volatile fatty acids (VFAs), methane (CH4) production, and ruminal bacteria and archaea populations ...

Ca2+‐Activated Cl− Channels: Do Bestrophins and TMEM16A Interact?

open access: yesActa Physiologica, Volume 242, Issue 6, June 2026.
ABSTRACT Aim Ca2+‐activated Cl– conductances are present in many cell types and are important for regulating membrane potential as well as other cellular functions. TMEM16A is widely accepted as the principal molecular basis for Ca2+‐activated Cl– conductances, but also members of the bestrophin family may be important for some Ca2+‐activated Cl ...
