Proneurogenic and microglial modulatory properties of botulinum neurotoxin in the hippocampus of aging experimental mice

Figure 4 Reverse transcription polymerase chain reaction results of tubulin and cyclooxygenase-2. A: Agarose gel images of the polymerase chain reaction products of cyclooxygenase (COX)-2 and Tubulin among control and botulinum neurotoxin (BoNT) groups, M indicates the 100bp DNA ladder; B: Bar graph of the densitometric analysis for the same in the hippocampal dentate gyrus of control and BoNT-treated groups. The expression of COX-2 has been significantly reduced in BoNT in comparison with the control group (^dP value ≤ 0.01). DG: Dentate gyrus; BoNT: Botulinum neurotoxin.
