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 ...

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 ...

Proceedings of the National Academy of Sciences of the United States of America, Vol. 118, No. 45 (November 9, 2021), pp. 1-12 (12 pages) Here, we study the dynamical expression of endogenously ...

Researchers have shown that harmful bonds between protein and DNA fuel immune attack in progeria. Pumping up a protein that cuts these bonds could prevent symptoms.

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 ...
