Figure 5: Effect of intranasal insulin on the levels of doublecortin and synaptic proteins.

Hippocampus extracts were measured via Western blots (a,c) and quantitative analysis was normalized to the GAPDH level (b,d). Data are expressed as the means ± SEM (n = 9–11 per group). *P < 0.05 versus the control group; #P < 0.05 versus the STZ/Sal group.
