Effects of n-3 polyunsaturated fatty acid and 17β-estradiol-3-benzoate (E2) on the expressions of phosphorylated adenosine monophosphate-activated protein kinase (p-AMPK, a), AMPK (b), peroxisomal proliferator-activated receptor α (PPAR, c), and carnitine palmitoyltransferase 1a (CPT1a, 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. Dagger values are significantly different (P < 0.05) among 0, 1, and 2 % n-3 within the corn oil- and E2-injected groups. Double dagger values are significantly different (P < 0.05) between 1 and 2 % n-3 within the corn oil- or E2-injected groups
