Acute intermittent hypoxia and rehabilitative training following cervical spinal injury alters neuronal hypoxia- and plasticity-associated protein expression.

Model: Unilateral (left) transection of the dorsolateral funiculus at C2 with a modified 25-gauge bevel-tipped needle after C2-C3 laminectomy and durotomy under isoflurane
Acute intermittent hypoxia raised neuronal HIF-1alpha after 1 and 7 days; vascular endothelial growth factor, brain-derived neurotrophic factor, TrkB and phosphorylated TrkB rose only after 7 days, at both cervical and lumbar levels.
