Effects of 17β-estradiol-3-benzoate (E2) on the expression of estrogen receptor α (ERα, a), ERβ (b), phosphorylated signal transducers and activators of transcription 3 (p-STAT3, c), and STAT3 (d) in liver. Values are expressed as mean ± SEM (n = 8); 0, 1, and 2 % n-3, 0, 1, and 2 % EPA + DHA diets with corn oil injection; 0, 1, and 2 % n-3 + E2, 0, 1, and 2 % EPA + DHA diets with E2 injection. Asterisk Values are significantly different (P < 0.05) between corn oil and E2 injection for diets containing the same amount of n-3 PUFA
