Low oxygen levels in the heart have long been known to produce life-threatening arrhythmias, even sudden death. Until now, it has not been clear how. "Our research shows that within seconds, at low levels of oxygen (hypoxia), a protein called small ubiquitin-like modifier (SUMO) is linked...
“Cells and tissues are constantly experiencing changes in oxygen availability,” Johnson said. “As an embryo(胚胎) grows and develops, and as muscles work, the oxygen available changes as the tissues themselves change. Cells need a way to adjust to the amount of oxygen they have, while stil...
