Fig. 5From: Reciprocal interactions between prostaglandin E2- and estradiol-dependent signaling pathways in the injured zebra finch brainCentral levels of PGE2 content in sham animals or following bilateral brain injury with estrogen receptor antagonism in adult male and female zebra finches. ER-α antagonism results in increased PGE2 levels compared to control injured brains (A). No such effect was detected following ER-β antagonism (B). Groups that do not share a letter are significantly different (p < 0.05)Back to article page
