Aequorin-based measurements of intracellular Ca2+-signatures in plant cells

open access: yesBiological Procedures Online, 2002
Due to the involvement of calcium as a main second messenger in the plant signaling pathway, increasing interest has been focused on the calcium signatures supposed to be involved in the patterning of the specific response associated to a given stimulus.

Two types of GLR channels cooperate differently in light and dark growth of Arabidopsis seedlings

open access: yesBMC Plant Biology, 2023
Background GLutamate Receptor-like (GLR) channels are multimeric, ionotropic, ligand-gated plant transmembrane receptors. They are homologous to mammalian glutamate receptors, iGLuRs, which are critical to neuronal function.

5‐HT2A receptor agonism by tert‐leucinamide and valinamide synthetic cannabinoids: In vitro and in vivo evidence

open access: yesBritish Journal of Pharmacology, Volume 183, Issue 16, Page 4715-4734, August 2026.
Abstract Background and Purpose New synthetic cannabinoid receptor agonists (SCRAs) are associated with severe adverse effects, including unexpected psychiatric symptoms. These compounds are mainly active through their potent agonism on the cannabinoid receptors CB1 and CB2.

Cloning and expression of aequorin photoprotein using intein tag

open access: yesIranian South Medical Journal, 2015
Background: Intein (INT), is the internal parts of the protein which can be separated from the immature protein during protein splicing process. This sequence requires no specific enzyme or cofactor for separation.

Insect Olfactory Receptor‐Expressing Sensor Cells for Colorectal Cancer Diagnosis Using Urine Samples

open access: yesCancer Medicine, Volume 15, Issue 4, April 2026.
We developed a novel, noninvasive diagnostic method for colorectal cancer using sensor cells expressing insect ORs that detect volatile organic compounds in urine samples. By analyzing the luminescence responses of sensor cells and applying machine learning, our model achieved 80% sensitivity and an ROC‐AUC of 0.84 in distinguishing colorectal cancer ...

The power of ionic movements in plants

open access: yesNew Phytologist, Volume 249, Issue 5, Page 2232-2240, March 2026.
Summary The movement of ion‐driven electrogenic events known as plant action potentials in the Venus flytrap Dionaea muscipula has first been recognized in Darwin's time. Besides electrophysiological techniques making use of current‐ and voltage‐recording electrodes, today an ever‐growing spectrum of tools has become available, that report online ...

Intracellular Ca2+ Regulation in Calcium Sensitive Phenotype of Saccharomyces cerevisiae

open access: yesHayati Journal of Biosciences, 2010
Intracellular cytosolic Ca2+ concentration accumulation plays an essential information in Saccharomyces cerevisiae i.e. to explain cellular mechanism of Ca2+ sensitive phenotype. Disruption both S. cerevisiae PPase PTP2 and MSG5 genes showed an inhibited

Imaging malaria parasites across scales and time

open access: yesJournal of Microscopy, Volume 301, Issue 2, Page 122-150, February 2026.
Abstract The idea that disease is caused at the cellular level is so fundamental to us that we might forget the critical role microscopy played in generating and developing this insight. Visually identifying diseased or infected cells lays the foundation for any effort to curb human pathology.

The role of His 16, Tyr 82 and Trp 86 in color shift, activity and thermostability of aequorin photoprotein

open access: yesIranian South Medical Journal, 2015
Background: Aequorin is a calcium sensitive photoprotein composed of apoaequorin (189 amino acid), oxygen and coelenterazine (imidazopyrazine chromophore). Activity of this photoprotein in calcium presence is blue photon emission (469 nm).
