The tumor suppressor p53 is a transcription factor that controls the expression of hundreds of genes. Emerging evidence suggests that the p53-induced RNA-binding protein ZMAT3 is a key splicing ...

Mitochondria structure. Illustrated by Jason Hoffman. Mitochondria are small, often between 0.5 and 3 micrometers, and are not visible under a microscope unless they are stained.

Exosomal mRNA transfer from non-neuronal cells to neurons under hypoxia drives hemoglobin expression and preserves mitochondrial homeostasis as an intercellular protective mechanism.

DNA from mitochondria (illustrated) has turned up in the nuclear genomes of brain cells. The implication for health is still unclear, but the insertions might be associated with life span ...

Researchers at the University of Jyväskylä have found that herpesvirus infection modifies the structure and normal function of the mitochondria in the host cell. The new information will help to ...

Mitochondria are key regulators of hormones, including cortisol, essential to the stress response, and the hormones of reproduction: estrogen, testosterone, and progesterone.

Mitochondria are organelles that are constantly undergoing fusion and fission events in order to maintain their structure and function. The balance between fission and fusion proteins regulates these ...

The SARS-CoV-2 virus hijacks our cellular power plants known as mitochondria. A new study hypothesizes that could potentially explain long Covid.

Studying the details of the mitochondria structure has been limited. Now, scientists at Scripps Research report an advanced imaging-based method that offers a new way of studying mitochondria.

LA JOLLA, CA—An advanced imaging-based method from scientists at Scripps Research offers a new way of studying mitochondria, which are best known as the “powerhouses” of cells. In their ...
