Increases in tyrosine hydroxylase (TH) expression in thoracolumbar dorsal root ganglias (DRGs) but not in sacral DRG following tri-nitrobenzene sulfonic acid (TNBS) treatment. At day 7 post TNBS treatment, animals demonstrated significant increases in the levels of TH immunoreactivity in T13 (A), L1 (B), and L2 (C) DRGs (2- to 3.5-fold) when compared to their matched controls. In sacral S1 DRG, there were no significant differences in the level of TH immunoreactivity detected between the control and TNBS-treated groups (D). Western blot analysis (E) confirmed the increase in TH levels in T13, L1, and L2 DRGs at day 7 of colitis (F). *P < 0.05.
