Arsenic Trioxide Modulates the Central Snail Neuron Action Potential
The electropharmacological effect of arsenic trioxide (As2O3) is unknown. The present study investigated the effects of As2O3 on spontaneous neuronal impulse activity. Methods: Intracellular recordings and the two-electrode voltage clamp method were used

Artificial Signal Transduction
Communication between and inside cells as well as their response to external stimuli relies on elaborated systems of signal transduction. They all require a directional transmission across membranes, often realized by primary messenger docking onto ...

Bi-modal distribution of the second messenger c-di-GMP controls cell fate and asymmetry during the caulobacter cell cycle [PDF]
Many bacteria mediate important life-style decisions by varying levels of the second messenger c-di-GMP. Behavioral transitions result from the coordination of complex cellular processes such as motility, surface adherence or the production of virulence ...

Cyclic di-GMP mediates a histidine kinase/phosphatase switch by noncovalent domain cross-linking [PDF]
Histidine kinases are key components of regulatory networks in bacteria. Although many of these enzymes are bifunctional, mediating both phosphorylation and dephosphorylation of downstream targets, the molecular details of this central regulatory switch ...

The Multiple Regulatory Relationship Between RNA-Chaperone Hfq and the Second Messenger c-di-GMP
RNA chaperone protein Hfq is an important post-transcriptional regulator in bacteria, while c-di-GMP is a second messenger signaling molecule widely distributed in bacteria.

Analysis of cyclic di-GMP signaling components in "caulobacter crescentus" behavior and cell cycle control [PDF]
Cell cycle progression and polar morphogenesis in Caulobacter crescentus are coordinated by the interplay of multiple proteins in time and space. One major regulatory factor is the second messenger cyclic di-GMP (c-di-GMP) therefore especially the ...
