Fresh air is good for nerves: hypoxia disturbs axon guidance

Article metrics

The transcription factor hypoxia-inducible factor 1 (HIF-1) triggers multiple cellular responses to cope with hypoxia. A study in this issue suggests that elevated HIF-1 also causes axon guidance defects under hypoxic conditions.
