HIF takes it up a notch.


Notch signaling is used to choose cell fates in many developmental contexts. New evidence shows that circulating blood cells in Drosophila, in the absence of Notch ligand provided by neighboring cells, activate Notch signaling through stabilization with the hypoxia-inducible factor-α (HIF-α) transcription factor. Although HIF-α is a key regulator of the low… (More)
