Cells have to invest a lot of energy to maintain this concentration gradient, especially when it comes to getting rid of calcium. 'It's like being on a rush-hour train in a city like Tokyo. When the ...

Calcium ions are essential for cells, but can be toxic in higher concentrations. A team of researchers has now designed and prepared a combination drug that kills tumor cells by modulating the calcium ...

No matter how important something is, too much of anything is bad for you. Scientists have now put that principle to work to kill cancer, with a new drug that causes calcium to build up and choke the ...

We have investigated the unusual observation that depolarization of rat basophilic leukemia cells in high potassium not only fails to induce secretion, but also inhibits the secretion induced when ...

In most cases the primary tumor is not the cause of death in cancer patients. More often, it is the migration of cancerous cells to other tissues in the body – a process called ‘metastasis’. In order ...

In cell signaling, calcium is king. The flux of calcium ions across cell membranes regulates cellular activities from muscle contraction to neuron firing to immune cell function. A talk I saw here at ...

“Our lab uses different polymers to interact with the nervous system. We think there's a window after injury that seems to mirror development,” said Paul George, a physician scientist at Stanford ...

Proceedings of the National Academy of Sciences of the United States of America, Vol. 105, No. 41 (Oct. 14, 2008), pp. 15749-15754 (6 pages) Many types of cells are able to accurately sense shallow ...
