KEGG pathway analysis showed that 576 up-regulated mRNAs were enriched in 66 pathways, including fourteen pathways that might be related to CHD, such as “RNA polymerase”, “mTOR signaling pathway”, “Ras signaling pathway”, “focal adhesion”, “metabolic pathways”, etc. And 336 down-regulated mRNAs were enriched in 26 pathways, including nine pathways that might be related to CHD, such as “metabolic pathways”, “NOD-like receptor signaling pathway”, “cell adhesion molecules”, “MAPK signaling pathway”, etc. (Fig. 2B). This evidence concerns the gene MTOR and coronary artery disorder.
