Data are presented as mean ± SEM (n = 8 males and n = 8 females per line). 18S was used for normalization.

¹CS, citrate synthase; HAD, β-hydroxyacyl-CoA dehydrogenase; LDH, lactate dehydrogenase; SLC2A1, solute carrier family 2 member 1; SLC2A3, solute carrier family 2 member 3; SLC2A8, solute carrier family 2 member 8; SLC2A12, solute carrier family 2 member 12.

²NS = not significant.

^a,bWithin a row, mean values without a common letter differ between groups (p ≤ 0.05).
