Figure 3From: Transcriptomic markers meet the real world: finding diagnostic signatures of corticosteroid treatment in commercial beef samplesPCA of the bovine skeletal muscle gene expression profiles. (A) PCA plot shows the two principal components of greatest variation which cover 42.8% (x-axis) and 28.4% (y-axis) of the total variance. (B) PCA plot excluding Holstein samples; x-axis and y-axis cover 56.2% and 14.7% of the total variance, respectively. Green triangles represent one set of controls (K, mixed-breed), green squares the second set of controls (C, Holstein), red trapeziums the animals positive for corticosteroid treatment at histological analyses and LC-MS (P) and black circles the unknown animals.Back to article page
