Researchers have found a molecular mechanism that prevents multiplication of potentially dangerous cells by measuring the duration of mitosis. They have shown that this mechanism -- the Mitotic ...

Viruses insert “transposable elements” into the genetic material of host cells to replicate. While cells’ defense mechanisms have learned to silence most of these viral insertions, a few “jumping ...

"The prize recognizes the confluence of two different approaches to learning about the molecular machinery regulating the cell cycle," says Ira Herskowitz, professor in the department of biochemistry ...

Amino acids are required for cell growth and proliferation, but it remains unclear when and how amino acid availability impinges on the proliferation-quiescence decision. Here, we used time-lapse ...

Post-mitotic neurons in the brain that re-enter the cell cycle quickly succumb to senescence, and this re-entry is more common in Alzheimer's disease, according to a new study published April 9 th in ...
