Figure 3

Functional classification of differentially expressed genes using IPA (Ingenuity Pathway Analysis) in different breeds of beef cattle. Positive z-scores are indicated with red bars and negative z-scores with blue bars. A positive z-score (2) indicates an increased predicted activation state, while a negative z-score (− 2) indicates a reduction in function. The number to the right of the bar is the number of differentially expressed (DE) genes. Up arrow and down arrow represent the DE genes up- and down-regulated in L-RFIfat compared to H-RFIfat steers, respectively. ANG, Angus; CHAR, Charolais; KC, Kinsella Composite.
