Table 1. Five neuronal regeneration-related genes with significant changes in the spiral ganglion after kainate treatment.

			Fold change vs. control
Gene	Protein	Functions in neurons	5 h	24h	72h
Nlgn2	Neuroligin-2	Involved in synapse formation, maturation and specification	-1.6	2.6*	-1.0
Ntrk3	Neurotrophic tyrosine kinase receptor type 3 (alias TrkC)	Promotes spiral ganglion neuronal survival in the inner ear	1.2	3.3*	-0.8
Rgmb	Repulsive guidance molecule family member B	Regulates neurite growth and axonal guidance; contributes to the patterning of the developing nervous system.	-1.6	2.4*	-0.9
Sema7a	Semaphorin7A	Involved in neuron migration and neurite growth	-1.9	4.5*	-1.4
Syt8	Synaptotagmin 8	Unclear	1.3	-1.8*	-1.3

* p < 0.005 as compared to the controls.

Negative numbers indicate downregulation and positive numbers indicate upregulation of gene expression relative to untreated controls.
