The PCA revealed that the expression signatures of RMRP, MIAT, NTT (Figure 5A) and the expression profiles of MALAT1, HSPA1A, and NLRP3 (Figure 5B) moderately differed between the thallium stress test (+) CAG (–) and thallium stress test (+) CAG (+) groups regardless of significant coronary artery stenosis. The gene discussed is NLRP3; the disease is coronary stenosis.
