Effect of Prenatal Protein Malnutrition on Long-Term Potentiation and BDNF Protein Expression in the Rat Entorhinal Cortex after Neocortical and Hippocampal Tetanization
Table 2
Changes in BDNF
expression (pg/mg wet tissue) in the left entorhinal cortex (EC) of 55–60-day-old normal
and prenatally malnourished rats two hours after applying ipsilateral
tetanizing stimulation to the occipital cortex (OC) or the CA1 hippocampal
region, as compared to BDNF levels in the right EC. Values are means ± SEM. The
number of samples in each group is shown in parentheses. BDNF concentrations in
right EC samples after tetanizing the left OC or left CA1 did not significantly
differ between them, and were therefore pooled. Comparisons of BDNF levels
between normal and malnourished groups were made using unpaired Student’s -test, and is the probability level for comparisons related to
the nutritional condition (NS = not significant). Comparisons between basal
BDNF levels (right EC) with those obtained after OC or CA1 tetanization (left
EC) were made using nonparametric ANOVA (Kruskal-Wallis test) followed by
Dunn’s multiple comparisons post-hoc test, and is the probability level for comparisons between
right and left EC samples (different superscripts indicate a significant
difference, ; NS = not
significant).
