Effects of different dietary starch sources on the relative mRNA expression of genes related to lipid metabolism in longissimus thoracis muscle of finishing pigs. The relative mRNA expression levels of peroxisome proliferator-activated receptor γ (PPARγ), fatty acid synthase (FAS), acetyl CoA carboxylase α (ACCα), Sterol regulatory element binding protein-1c (SREBP-1C), lipoprotein lipase (LPL), carnitine palmitoyl transferase 1B (CPT1B), fatty acid transport protein 1 (FATP1), and hormone-sensitive lipase (HSL) were normalized using β-actin as an internal control. The values are means ± SEM (n = 8). The P values indicate the effects of different dietary starch sources with different amylose/amylopectin ratios by one-way ANOVA and polynomial contrasts- linear and quadratic analyses, respectively. *P < 0.05, **P < 0.05 (one-way ANOVA with a Tukey's post-hoc test). Abbreviations: TS, tapioca starch; CS, corn starch; PS, pea starch
