Western blot data were obtained from tissue collected at time points when behavioral pharmacology data were collected as indicated in Fig.4. The number of plus signs in each column represents the relative degree of significant α2δ-1 subunit up-regulation compared within DRG or spinal cord samples only; Minus sign indicates no significant change.
