Fig. 4

Detection of neurogranin peptides. The figure shows signal intensities, means and SD of 6 neurogranin (NEUG)-derived peptides (NEUG 53–78, NEUG 54–78, NEUG 55–78, NEUG 54–75, NEUG 59–78 and NEUG 55–69) in 16 brain samples (LS linagliptin-stroke, VS vehicle stroke, LC linagliptin control, VC vehicle control). The star marks significant differences (ROC-AUC = 1, p < 0.005) between LS and the remainder of samples. The corresponding amino acid sequence is depicted at the top of each graph
