Cancer cells can acquire energy-generating structures called mitochondria from nearby nerve cells, which seems to aid their ...

Cell membranes protect and organize cells. All cells have an outer plasma membrane that regulates not only what enters the cell, but also how much of any given substance comes in. Unlike ...

It has been known for several years that abnormal chromosome numbers lead to protein imbalances in the affected cells.

A recent study published in Proceedings of the National Academy of Sciences of the United States of America (PNAS) describes a unique organization of mitochondria in photoreceptor cells that may be ...

Oncogene - Role of mitochondrial membrane permeabilization in apoptosis and cancer. ... One mode involves signalling by death receptors in the plasma membrane (extrinsic) ...

A recent study published in Proceedings of the National Academy of Sciences of the United States of America (PNAS) describes a unique organization of mitochondria in photoreceptor cells that may be ...

A new study reveals that the protein MTCH2, which is essential in a variety of cellular processes, is responsible for shuttling various other proteins into the membrane of mitochondria. The ...

“The mitochondrial permeability transition pore (MPTP) is a megachannel in the inner mitochondrial membrane that opens in response to high matrix Ca2+ and oxidative stress,” the authors noted.

The cell’s mitochondria (in green) gather around the invader and begin to shed vesicles (green bubbles) made of mitochondrial outer membrane. Sometimes, the vesicles can form elaborate ...

One feature of eukaryotes is a complex endomembrane system, comprised of the various membranes that are suspended inside the cytoplasm of a eukaryotic cell. These critical membranes create different ...

Mitochondria are often called the powerhouses of the cell. ... Unlike other organelles (miniature organs within the cell), mitochondria have two membranes, an outer one and an inner one.

MTCH2's ability to shuttle proteins from the cytoplasm into the mitochondrial membrane is likely due to its specialized shape. The researchers ran the protein's sequence through Alpha Fold, an ...
