In CPH and PAH positive correlation module, there were 71 common genes (Figure 3(a)), GO analysis included “protein targeting to vacuole” “P53 signaling pathway,” “neutral lipid biosynthesis,” and “cysteine-type endonuclease regulator activity involve in apoptotic process” (Figure 3(a)). This evidence concerns the gene TP53 and pulmonary arterial hypertension.
