Researchers have shown that the "pacemaker" controlling yeast cell division lies inside the nucleus rather than outside it, ...

In a study that may guide drug design, researchers find organelles encounter varying levels of resistance, depending on their size and speed, as they move through a cell's cytoplasm.

ABOVE: Color photograph of the retina of a patient with atrophic macular degeneration JAYAKRISHNA AMBATI. O ver the past decade, there have been scattered reports of mammalian cells’ own DNA being ...

In the context of cytoplasm, viscoelasticity represents how quickly a cell can change shape by altering its cytoskeleton. The cytoskeleton can create impediments to movement inside the cell; because ...

Back in 2018, the lab of Christine Mayr, MD, PhD, at Memorial Sloan Kettering Cancer Center (MSK) introduced the world to a key cellular component that had been hiding in plain sight.

The cytoplasm is the largest part of the cell by volume and hence its rheology sets the rate at which cellular shape changes can occur. Recent experimental evidence suggests that cytoplasmic ...

Inching along, a DNA-preserving mechanism can ultimately defeat the transposon, a danger that jumps. This mechanism is part of a larger process through which tiny pieces of RNA protect ...

Earlier this year, Ambati’s team uncovered an important clue. Surprisingly, in cultured human retinal pigmented epithelium cells, they found that DNA copies of Alu can occur in the cell cytoplasm—in ...
