Abstract: Cold shock triggers an immediate rise in the cytosolic free calcium concentration ([Ca2+]cyt) in Arabidopsis thaliana and this cold-induced elevation of [Ca2+]cyt is inhibited by lanthanum or EGTA. It is suggested that intracellular calcium mainly… read more here.

DOI: 10.1038/s41598-019-46856-8
Abstract: Like many viruses, rotavirus (RV) dysregulates calcium homeostasis by elevating cytosolic calcium ([Ca2+]cyt) and decreasing endoplasmic reticulum (ER) stores. While an overall, monophasic increase in [Ca2+]cyt during RV infection has been shown, the nature of… read more here.

DOI: 10.1093/jxb/ery056
Abstract: Ascorbate is not often considered as a signalling molecule in plants. This study demonstrates that, in Arabidopsis roots, exogenous l-ascorbic acid triggers a transient increase of the cytosolic free calcium activity ([Ca2+]cyt.) that is central… read more here.

DOI: 10.1093/plphys/kiac324
Abstract: Diatoms are a group of microalgae that are important primary producers in a range of open ocean, freshwater and intertidal environments. The latter can experience significant long- and short-term variability in temperature, from seasonal variations… read more here.

Abstract: Extracellular ATP (eATP) increases cytosolic free calcium ([Ca2+ ]cyt ) as a specific second messenger "signature" through the plasma membrane DORN1/P2K1 receptor. Previous studies revealed a biphasic signature in Arabidopsis thaliana roots that is altered… read more here.

Effects of arginase inhibition on myocardial Ca2+ and contractile responses

DOI: 10.14814/phy2.15396
Abstract: Nitric oxide (NO) is thought to increase cardiac contractility by increasing cytosolic Ca2+ concentration ([Ca2+]cyt) during excitation. Alternatively, NO could increase the sensitivity of the contractile response to [Ca2+]cyt (Ca2+ sensitivity). Arginase regulates NO production… read more here.
