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 ...

Each day, hundreds of billions of cells in our body cycle through a period of growth and division. Yet in that time, only about 30 minutes is spent on the critical orchestration of mitosis, when ...

Limonoids, produced during metabolism, are found in high levels in seeds, fruits, and peels of citrus fruits like lemons, limes, and oranges.  Munroni | Cancer ...

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 ...

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 ...

Biologists have uncovered a quality control timing mechanism tied to cell division. The 'stopwatch' function keeps track of mitosis and acts as a protective measure when the process takes too long, ...
