If cytoplasm is more poroelastic, an organelle needs more effort to move water out of the way. In the context of cytoplasm, viscoelasticity represents how quickly a cell can change shape by altering ...

In addition to the nucleus, eukaryotic cells may contain several other types of organelles, which may include mitochondria, chloroplasts, the endoplasmic reticulum, the Golgi apparatus, and ...

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.

Intracellular endosymbionts that originally descended from free-living prokaryotes have been important in the evolution of eukaryotes by giving rise to two cytoplasmic organelles. Mitochondria ...

Cambridge, Mass. – August 14, 2014 – Conventional wisdom holds that the cytoplasm of mammalian cells is a viscous fluid, with organelles and proteins suspended within it, jiggling against one ...

A longside organelles such as mitochondria and Golgi apparatuses, membraneless structures help compartmentalize the cytoplasm, as well as the interior of the nucleus. In contrast to organelles with a ...

Conventional wisdom holds that the cytoplasm of mammalian cells is a viscous fluid, with organelles and proteins suspended within it, jiggling against one another and drifting at random. However ...

Organelle Without Borders, or How TIGER Earned Its Stripes. Unlike other well-known organelles — say the nucleus or mitochondria — the TIGER domain is not enclosed by a membrane. ... She also thinks ...

A utophagy—the process by which a cell digests and recycles various molecules and organelles in its cytoplasm—is critical for maintaining homeostasis and for helping cells survive low-nutrient ...

Worn-out proteins, malfunctioning organelles, invading microorganisms: all are swept up by tiny internal "vacuum cleaners" that keep a living cell healthy. If the process, called autophagy, can be ...
