How planarians can regenerate during periods of starvation

Planarians are able to survive long periods of starvation unscathed by maintaining their stem cell pool and regenerative capacity. The molecular processes behind this are not yet known. Jena researchers from the Leibniz Institute ...

Cellular stress causes cancer cell chemoresistance

There is a broad range of mechanisms associated with chemoresistance, many of which to date are only poorly understood. The so-called cellular stress response—a set of genetic programs that enable the cells to survive under ...

Cells put off protein production during times of stress

Living cells are like miniature factories, responsible for the production of more than 25,000 different proteins with very specific 3-D shapes. And just as an overwhelmed assembly line can begin making mistakes, a stressed ...
