The speed with which the wave moves suggests that it travels through gap junctions and is made up either of calcium ions or some other small signaling molecule.

Her team discovered that stem cells take up calcium phosphate to produce ATP, a metabolic molecule, which then breaks down into adenosine and signals the stem cells to become osteoblasts.

In this study, the team, which included Dr. Meerim Nurbaeva and Miriam Eckstein in Dr. Lacruz's lab, for the first time used freshly dissected enamel cells (ameloblasts) from rodent teeth to modulate physiological processes in order to understand the contribution of CRAC channels in enamel calcium signaling.

First, looking at a study of 185 cases of childhood epilepsy, Wittkowski's team found that mutations in genes that control axonal guidance and calcium signaling — both of which are important early in the developing brain when neurons are forming the appropriate connections — led to increased chances of having the disorder.

Of general importance for systemic calcium signaling is the wounding of the vascular system of the leaf, which is also responsible for the internal transport of water and nutrients in the plant.

Enikolopov says: «If the calcium signal coincides in time with a wave or a puff of nitric oxide — which might be produced even by a neighbouring cell — then this weak calcium signal effectively becomes a strong signal, in terms of its consequences.»

This study demonstrates that calcium signals, which are necessary for eliciting plant defense responses, and their spatial and temporal expansion can be visualized.

Moreover, the scientists showed that calcium signaling can be studied directly in intact plants in different physiological and ecological contexts, which helps to better understand its role as a secondary messenger in plants.

«We succeeded in visualizing the dynamic signal processing of intracellular calcium as a secondary messenger which is elicited by insect feeding and transmitted systemically to unattacked areas of the plant,» Axel Mithöfer, the leader of the project group «Physiology of Plant Defense» in the Department of Bioorganic Chemistry, summarizes the results of the study.

In order to visualize this signal, the scientists performed experiments with transgenic Arabidopsis plants which were genetically modified to express a protein in the cytosol, the liquid inside the cells, which breaks down and releases light energy after it has bound calcium ions.

«Surprisingly, we found that calcium avoidance occurred through two mechanisms: activation of a unique class of GRNs, distinct from those that sense bitter compounds and which cause a stop - feeding signal when activated.

The researchers studied calcium channels in neurons, which allow for the transport of calcium ions from one nerve cell to another, helping the cells transmit itch signals from the skin to other cells in the spinal cord.

It is not clear how this calcium signal might relate to mouse embryos, in which rotating cilia help set up left and right sides (ScienceNOW, 3 July, 2002).

Potential future options include solutions that would mimic either benign cysts or tiny bits of calcium called microcalcifications, which can signal cancer.

Rothman and Scheller collaborated and proposed that NSF and SNAP form part of the vesicle fusion machinery in neurons, and that synaptotagmin served as a clamp which prevented the fusion process from happening until a calcium signal arrived.

In addition, caffeine may increase the activity of several signaling enzymes, including the calcium - dependent protein kinase and protein kinase B (also called Akt), which have roles in muscle glucose uptake during and after exercise.

Both DAG and calcium are essential second messengers which activate downstream signaling components such as protein kinase C and calmodulin dependent kinase.

Calcium ions also allow neurons to signal one another, which ties in to the gut - brain - skin axis.
