doi: 10.1101/2025.03.31.646417
Figure Lengend Snippet: Mature BDNF and proBDNF levels were measured by Western blot in brain lysates derived from mice exposed to either vehicle or DFP (4.0 mg/kg), followed by treatment with saline, GM1, or GD3 (5 mg/kg/day for 7 days). (A) Representative blot illustrating proBDNF (32 kDa) and BDNF (14 kDa). CTX, cortex; PFC, prefrontal cortex; HIP, hippocampus; SVZ, subventricular zone. (B) The data presented in the bar graphs were obtained from densitometry measurements of the bands for proBDNF, BDNF, and actin . Ratios of proBDNF and BDNF to actin were calculated for each replicate sample. Results are expressed as means ± S.E.M. of ≥3 replicates per condition. *P < 0.05 and **P < 0.01 indicates significant differences between indicated groups, as calculated using one-way ANOVA with Tukey’s multiple comparison test.
