Figure 5: This figure represents the Western blot studies of glutaminase (GLS) within the L4 DRG from AIA and control rats. (a) Western blot represents GLS immunoreaction (65 kDa) from the L4 DRG of AIA and control rats. Note the increase of GLS immunoreaction within the AIA animals. (b) This graph represents the statistical analysis of the GLS immunoreactivity between AIA and control rats. A significant increase (* ) was found between the AIA rats when compared to controls.
