Table 1. The percentage of the cells expresing β-catenin in the membrane, cytoplasm and nuclei of the L5 DRGs shown in Fig 1A.

Beta-catenin expressions
	Ipsilateral DRGs		Contralateral DRGs
	M	M+C+N	M	M+C+N
Sham	43.0 ± 3.6	57.0 ± 3.6	40.0 ± 6.2	60.0 ± 6.2
CCI	87.5 ± 8.5 a	87.5 ± 8.5 a	65.1 ± 3.4 a	34.9 ± 3.4 a
CCI+diclofenac	40.9 ± 6.8 b	59.1 ± 6.8 b	72.3 ± 9.2	27.7 ± 9.2

The L5 DRG specimens were obtained from the same paraffin-embedded L5 DRG sections of CCI rats shown in our previous study [16]. The data were obtained from four rats in each group.

^a denotes P < 0.01 versus the contralateral L5 DRGs of sham rats;

^b denotes P < 0.01 versus the ipsilateral L5 DRGs of CCI rats.
