Receptor-activated cytoplasmic calcium (Ca2+) oscillations have been investigated in single pancreatic acinar cells by microfluorimetry (Fura-2 as indicator). At submaximal concentrations of the agonists acetylcholine (ACh) and cholecystokinin octapeptide (CCK-8), both give rise to oscillatory changes in the cytosolic free calcium concentration ([Ca2 ...

Isopeptides of the newly discovered peptide family, endothelins (ET), caused a concentration-dependent increase in intracellular free [Ca2+] ([Ca2+]i) in human glomerular mesangial cells. ET isopeptides and sarafotoxin S6b caused transient and sustained [Ca2+]i waveforms which resulted from mobilization of intracellular Ca2+ stores and from Ca2+ influx

Receptor-activated cytoplasmic Ca2+ oscillations have been investigated using both single cell microfluorometry and voltage-clamp recording of Ca(2+)-dependent Cl- current in single internally perfused acinar cells. In these cells there is direct experimental evidence showing that the ACh-evoked [Ca2+]i fluctuations are due to an inositol trisphosphate-

Abstract A03: SCFCyclin F connects AKT signaling to the core cell cycle oscillator
Molecular Cancer Research, 2016Abstract Cell proliferation is governed by the presence of growth factors, and in their absence normal cells cease to progress through the cell cycle. The waves of Cyclin Dependent Kinase (CDK) activity constituting the core of the cell cycle oscillator are driven by cyclin synthesis and its subsequent destruction by the Anaphase ...

Modelling of simple and complex calcium oscillations
European Journal of Biochemistry, 2002This review provides a comparative overview of recent developments in the modelling of cellular calcium oscillations. A large variety of mathematical models have been developed for this wide‐spread phenomenon in intra‐ and intercellular signalling. From these, a general model is extracted that involves six types of concentration variables: inositol 1,4,

Human bone marrow-derived mesenchymal stem cells (hMSCs) have the potential to differentiate into several types of cells. Calcium ions (Ca(2+)) play an important role in the differentiation and proliferation of hMSCs. We have demonstrated that spontaneous [Ca(2+)](i) oscillations occur without agonist stimulation in hMSCs.

We studied effects of heat acclimation (HA) and acute heat stress (HS) on Ca2+ signal oscillations following supramaximal carbamyl-choline (CCh) stimulation, using HSY cell line as a model. In the control cells, oscillations decreased their amplitude with time.

Regulation of Cell Division Cycles by Circadian Oscillators: Signal Transduction Between Clocks
1997An important consideration for maximizing the results of radio- and chemotherapy of mammalian cancers is that of host tolerance. It is unfortunate that in most of the earlier cancer work there is little mention of the role of rhythmic variations (particularly circadian periodicities) in the susceptibility of the whole organism to the toxicity of the ...

Cell Stem Cell
Stem cells are known for their resilience and enhanced activity post-stress. The mammary gland undergoes frequent remodeling and is subjected to recurring stress during the estrus cycle, but it remains unclear how mammary stem cells (MaSCs) respond to the stress and contribute to regeneration.
