Many of us remember from high school biology class that mitochondria are the cell's "power plants." These small kidney-bean-shaped structures are what convert nutrients from food into ATP—the cell's ...

Senescent cells remain alive after they stop dividing, earning the nickname “zombie” cells because they persist in tissue ...

Cardiolipin sits right in that membrane. It's a phospholipid, but an unusual one: instead of the two fatty acid chains found in most phospholipids, it has four. You'll find it mainly in the inner ...

The structural and functional characteristics of mitochondria shape their role as signaling organelles, with far-reaching effects regarding immune responses, inflammatory processes, and diseases. A ...

After a heart attack, the heart struggles to recoup and maintain energy. One-third of patients develop heart failure as a result—a condition that impacts 6.8 million Americans and carries a high ...

A newly identified identified cellular mechanism allows mitochondria to recycle localized damage and maintain healthy function. Mitochondria, the so-called "powerhouse of the cell," depend on a newly ...

Researchers at Karolinska Institutet have shown that mutations in mitochondrial DNA (mtDNA), which accumulate in many tissues ...

Cancer biology—and, in turn, cancer treatment—have come a long way in the last few decades. Most people recognize this ...

Mitochondria power eukaryotic cells to carry out their varied functions. However, these organelles themselves may also be more than they appear, providing scientists with continuous questions to ...
