The segregation of yolk from the surrounding cytoplasm in the very early fish embryo is a key process for the development of fish larva. To identify its underlying mechanisms, biologists at the ...

An international team of scientists has unveiled the most comprehensive model yet that explains how cells control the flow of materials in and out of their nuclei—solving one of biology's oldest ...

The biophysical properties of the cytoplasm rapidly change in response to different cellular stresses. Cells are highly crowded with mesoscale particles (10 nm to 1 mm in diameter) and this crowding ...

Over the past decade, there have been scattered reports of mammalian cells’ own DNA being found in the cytoplasm, mainly in the context of disease and aging. While it is not unusual to find DNA from ...

New findings provide details about the hidden organization of the cytoplasm, showing it makes a big difference where in that cellular broth that messenger RNA (mRNA) get translated into proteins. The ...

MicroRNAs (miRNAs) are small non-coding RNAs that have well-characterized roles in cytoplasmic gene regulation, where they act by binding to mRNA transcripts and inhibiting their translation (i.e.
