Upregulation of PMA-induced PGP9.5 and VEGF expression in the spinal cord and the DRG. (A, B) Expression of PGP9.5 and VEGF in the spinal cord after PMA treatment was determined by densitometric analysis on Western blots using GAPDH as the internal control. Compared with the control and DMSO group, *P < 0.05, **P < 0.01, ***P < 0.001; n=5 for each group. (C, D) Expression of PGP9.5 and VEGF in the DRG after PMA Treatment was determined by densitometric analysis on Western blots using GAPDH as the internal control. Compared with the control and DMSO group, *P < 0.05, **P < 0.01, ***P < 0.001; n=5 for each group.

Abbreviations: DRG, dorsal root ganglion; PGP, protein gene product; PGP9.5, protein gene product 9.5; VEGF, vascular endothelial growth factor; PMA, TPA, Phorbol 12-myristate 13-acetate.
