  1. Values are normalised (by cofilin-2) gene expression ratios between fish fed VO in relation to FO for each family group or of Lean fish in relation to the Fat group when fed either one of the diets. Values in bold are significantly different, at p < 0.05 (REST 2008).
  2. fad: fatty acyl desaturase (Δ5 and Δ6); elovl: elongase (three different transcripts); FAS: Fatty acid synthase; PPARs; peroxisome proliferator-activated receptors (three isoforms); SREBP-1: Sterol regulatory element binding protein-1; GST: glutathione S-transferase A; HOX: heme oxygenase 1; GFPT1: glutamine-fructose-6-phosphate transaminase 1; ApoB: apolipoprotein B; EL: endothelial lipase; LPP2: lipid phosphate phosphohydrolase 2; AGPAT: 1-acyl-sn-glycerol-3-phosphate acyltransferase.
