Gene expression profiles in the spinal cord below the lesion level and influence of treadmill locomotor training

Traumatic spinal cord injury (SCI) often leads to loss of locomotor function. Neuroplasticity of spinal circuitry underlies some functional recovery and therefore represents a therapeutic target to improve locomotor function following SCI. However, the cellular and molecular mechanisms mediating neuroplasticity below the lesion level are not fully understood. The present study performed a gene expression profiling in the rat lumbar spinal cord at 1 and 3 weeks after contusive SCI at T9. The below-level gene expression profiles were compared with those of animals that were subjected to treadmill locomotor training.
