Fig 5. CRF, Ucn2, and CRF receptor expression in ileal and colonic mucosa in pigs subjected to chronic social stress.

Relative mRNA expression of (A) ileal CRF, (B) ileal CRF₁, (C) ileal Ucn2, (D) ileal CRF₂, (E) colonic CRF, (F) colonic CRF₁, (G) colonic Ucn2, and (H) colonic CRF₂ in pigs subject to chronic social stress. All values are relative to the expression levels measured in control pigs. Values are means ± SE (n = 6 per treatment). ** indicates significant difference, P ≤ 0.01; * indicates significant difference, P ≤ 0.05; P = 0.09 (D) by Student’s T-test.
