Fig. 2From: Reciprocal interactions between prostaglandin E2- and estradiol-dependent signaling pathways in the injured zebra finch brainCentral levels of prostaglandin E2 (PGE2) in sham animals or following bilateral injury with prostanoid receptor antagonism in adult male and female zebra finches (A and B). Treatment with EP-3 or EP-4 antagonist during brain injury does not affect the induction of PGE2 (A and B) compared to sham controls. However, receptor antagonism decreases downstream signaling (PKA) compared to control-injured brains (C). Dashed line represents injured controls (controls set to 1 for fold change calculation). *p < 0.05Back to article page
