In a landmark study led by the University of Maryland School of Medicine, researchers discovered for the first time that a certain kind of protein similar to hemoglobin, called cytoglobin, plays an ...

Researchers have discovered that a certain kind of protein similar to hemoglobin, called cytoglobin, plays an important role in the development of the heart. Specifically, it affects the correct ...

How proteins evolved the ability to form complexes made up of multiple subunits—and what functions this new structure enabled in early multimeric proteins—isn’t well understood. To better understand ...

Video shows zebrafish with mutant gene lacking cytoglobin. Heart defects are seen with heart on the right side instead of the left side with blood flow looping to the left instead of the right.

The team used CRISPR gene editing technologies to knock out the cytoglobin gene in zebrafish. The lack of cytoglobin caused the development of embryos with a mirrored heart, meaning the heart had a ...

Hemoglobin helps red blood cells carry oxygen to your muscles and tissues. Abnormal hemoglobin levels can be a sign of several health problems. Hemoglobin is a component of your blood that delivers ...
