Ca2+ signals co-ordinate zygotic polarization and cell cycle progression in the brown alga, Fucus serratus. [PDF]
, 2008 Zygotes of the fucoid brown algae provide excellent models for addressing fundamental questions about zygotic symmetry breaking. Although the acquisition of polarity is tightly coordinated with the timing and orientation of the first asymmetric division ...

Ca2+-Calmodulin-dependent Facilitation and Ca2+ Inactivation of Ca2+ Release-activated Ca2+ Channels [PDF]
Journal of Biological Chemistry, 2005 In non-excitable cells, one major route for Ca2+ influx is through store-operated Ca2+ channels in the plasma membrane. These channels are activated by the emptying of intracellular Ca2+ stores, and in some cell types store-operated influx occurs through Ca2+ release-activated Ca2+ (CRAC) channels. Here, we report that intracellular Ca2+ modulates CRAC

The Response of Physarum polycephalum to Extracellular Ca2+: Studies on Ca2+ Nutrition, Ca2+ Fluxes and Ca2+ Compartmentation [PDF]
Journal of General Microbiology, 1979 Summary: The calcium requirement for optimal growth of Physarum polycephalum is between 0.05 and 2.5 mM. Media without Ca2+ will not support growth though Ca2+-chelating agents, such as EDTA and EGTA, do not have any marked effect on Ca2+ availability at the low pH used to culture this organism. The intracellular Ca2+ concentration varies approximately

Ca2+-dependent Transcriptional Control of Ca2+ Homeostasis [PDF]
Journal of Biological Chemistry, 2012 Intracellular free Ca(2+) ions regulate many cellular functions, and in turn, the cell devotes many genes/proteins to keep tight control of the level of intracellular free Ca(2+). Here, we review recent work on Ca(2+)-dependent mechanisms and effectors that regulate the transcription of genes encoding proteins involved in the maintenance of the ...

Exosomal miR-29b found in aqueous humour mediates calcium signaling in diabetic patients with cataract [PDF]
International Journal of Ophthalmology, 2021 AIM: To investigate the role of exosomal miR-29b and Ca2+ in regulating the function of human lens epithelial cells (HLECs). METHODS: Exosomes were isolated from human aqueous humour (AH) by ultracentrifugation, and visualized by nanoparticle tracking ...

Effects of Monovalent and Divalent Cations on Ca2+ Fluxes Across Chromaffin Secretory Membrane Vesicles [PDF]
, 1983 : Bovine chromaffin secretory vesicle ghosts loaded with Na+ were found to take up Ca2+ when incubated in K+ media or in sucrose media containing micromolar concentrations of free Ca2+. Li+- or choline+loaded ghosts did not take up Ca2+.

GTP and Ca2+ Modulate the Inositol 1,4,5-Trisphosphate-Dependent Ca2+ Release in Streptolysin O-Permeabilized Bovine Adrenal Chromaffin Cells [PDF]
, 1991 The inositol 1,4,5-trisphosphate (IP3)-induced Ca2+ release was studied using streptolysin O-permeabilized bovine adrenal chromaffin cells. The IP3-induced Ca2+ release was followed by Ca2+ reuptake into intracellular compartments.

ER localized bestrophin1 activates Ca2+ dependent ion channels TMEM16A and SK4 [PDF]
, 2009 Bestrophins form Ca2+ activated Cl- channels and regulate intercellular Ca2+ signaling1. We demonstrate that bestrophin 1 is localized in the endoplasmic reticulum (ER), where it physically interacts with stromal interacting molecule 1 (Stim1), the ER ...
