Figure 4. Bdnf mRNA expression in the hippocampus.
Non-PS control animals of each strain significantly up-regulate Bdnf mRNA after an acute stress (*, p<0.05). PS Sprague-Dawley and Lewis rats had higher baseline Bdnf expression (**, p<0.05), which was unchanged after acute stress in the Sprague-Dawleys, but significantly decreased in the Lewis rats (***, p<0.05). PS did not change expression in the Fischer strain.
