Diplonemid flagellates are among the most abundant marine microeukaryote species in world ocean habitats. 1 Diplonemids are recognized for their complex organelle structure and mitochondrial DNA. 2 ...

Cells use their molecular architecture to regulate their metabolic functions, and repairing diseased cells' architecture to a healthier state can also repair metabolism, according to a study led by ...

Researchers have shown that a protein called HKDC1 is a new target of another protein, TFEB, and plays key roles in maintaining the stability of both mitochondria and lysosomes. HKDC1 is essential for ...

In the beginning, there was boredom. Following the emergence of cellular life on earth, some 3.5 billion years ago, simple cells lacking a nucleus and other detailed internal structure dominated the ...
