FIGURE 7.

Relative mRNA expression of genes coding for fatty acid binding protein 4 (FABP4) and cluster of differentiation 36 (CD36). mRNA expressions were assessed in pectoralis major muscles from a slow-growing genotype (SG) and a fast-growing genotype macroscopically free of defects (FG-C) or affected by White Striping (FG-WS), Wooden Breast (FG-WB), or both White Striping and Wooden Breast (FG-WSWB). FABP4 and CD36 expressed also more in fast- than in slow-growing muscles, especially in muscles affected by White Striping. Absolute mRNA levels of targeted genes were corrected for 18S ribosomal RNA levels to give a relative mRNA level. For each gene, different letters indicate significant differences between groups (P ≤ 0.05).
