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 ...

Hemoglobin, long celebrated for ferrying oxygen in red blood cells, has now been revealed to play an overlooked—and potentially game-changing—antioxidant role in the brain. "The key was to uncover ...

Scientists have long been puzzled by how maturing red blood cells manage to produce all the hemoglobin they need to carry ...

Topline data for the once-daily PKR activator etavopivat demonstrate a 27% reduction in vaso-occlusive crises and a robust hematologic response in patients with SCD.

Scientists at St. Jude Children's Research Hospital have shown how a protein responsible for adapting to low oxygen conditions (hypoxia), causes increased expression of fetal hemoglobin (HbF) in ...

Sickle cell disease (SCD) is a genetic disorder that causes red blood cells to take the shape of a sickle or a letter “C.” Levels of hemoglobin, a protein that helps carry oxygen on red blood cells, ...

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.
