Abstract

The correlation of expression pattern of candidate genes in PPAR signalling pathway with meat quality traits in Longissimus dorsi muscle of pigs was investigated. Meat quality traits were measured and correlated with the candidate genes mRNA expression, which included peroxisome proliferator-activated receptor alpha gene (PPARα), peroxisome proliferator-activated receptor gamma gene (PPARγ), stearoyl-CoA desaturase gene (SCD), lipoprotein lipase gene (LPL), and phosphoenolpyruvate carboxykinase 2 gene (PCK2). Results showed that expressions of SCD and PCK2 were correlated with intramuscular fat content (P < 0.05). PPARα and PPARγ showed negative correlations with water loss and colour score (P < 0.05). SCD was positively correlated with marbling score and negatively correlated with shear force (P < 0.05). LPL was correlated with b* value, shear force, and moisture content (P < 0.05). PCK2 had a positive correlation (P < 0.05) with colour score. The revealed correlations indicate that these genes in PPAR signalling pathway are important for meat quality traits in pigs, and the further evaluation and investigation of these genes would help us better understand and utilize the regulation mechanisms of porcine meat quality.
