| Annotation description: | Fig.1: "Ghrelin was applied for 60 min (Fig. 1A3 and C). In control slices, the average spine density was 0.302/unit area ± 0.039 SEM (n = 30 images taken from 10 slices) (Fig. 1A2). Ghrelin (200 nM) increased the average spine density to 0.499/unit area ± 0.058 SEM (n = 30 images taken from 10 slices, p < 0.001) (Fig. 1A3). The effect of ghrelin was blocked by the ghrelin receptor antagonist, D-Lys3-GHSR-6 (100 uM) (0.333/unit area ± 0.041 SEM, n = 30 images taken from 10 slices), suggesting the involvement of the ghrelin receptor activation and possible downstream signaling cascades in the induction of ghrelin-mediated changes in dendritic spines." |
