Comparing the mRNA expression profile and the genetic determinism of intramuscular fat traits in the porcine gluteus medius and longissimus dorsi muscles

<b>Background</b> Intramuscular fat (IMF) content and composition have a strong impact on the nutritional and organoleptic properties of porcine meat. The goal of the current work was to compare the patterns of gene expression and the genetic determinism of IMF traits in the porcine <i>gluteus medius </i>(GM) and <i>longissimus dorsi </i>(LD) muscles.

<b>背景</b> 肌内脂肪（Intramuscular fat, IMF）的含量与组成对猪肉的营养特性及感官品质具有显著影响。本研究旨在对比猪臀中肌（<i>gluteus medius</i>, GM）与背最长肌（<i>longissimus dorsi</i>, LD）的基因表达模式，以及肌内脂肪性状的遗传决定机制。
