Need oxygen? Cells know how to spend and save
...cells survive when oxygen is low, such as during a heart
attack or stroke. The researchers set out to figure out if the sensor protein HIF-1 triggers the COX-swapping. By examining the gene control regions of COX4, they found that the HIF-1 sensor switched on COX4-2 activity when oxygen is low. And they...
