Quantification analysis of DA, CASP3, GST, BDNF and NT3 levels in the zebrafish brain. Interestingly, DA level showed a downward trend in NT3 groups compared to the PD model with the lowest level in day 10 group with highest NT3 level in the similar group. The CASP3 level was significantly lower with a higher GST level in NT3 groups than that in PD group especially in day 3 and day 5 groups. While BDNF was equivocal except for NT3.5 group where the level dropped compared to vehicle group, however equivocal to the corresponding PD group. # describes the significant difference between the MPTP and vehicle groups with #p < 0.05, ##p < 0.01; * describes the statistically significant difference between the NT3 treatment group and its corresponding MPTP group with *p < 0.05, and **p < 0.01; α describes the significant difference between the NT3 group and the vehicle with α p < 0.05, αα p < 0.01; κ describes the significant difference between NT3.3, NT3.5 and NT3.5 with κ p < 0.05 and κκ p < 0.01.
