Fig. 7From: Integrated analysis of gene expression changes associated with coronary artery diseaseThe relationship among CAD, genes and several environmental exposures and validation with RT-qPCR. a The associations among CAD, genes and environmental exposures. Positive correlation is marked with red, and negative correlation is marked with green. Scale represents the specific correlation coefficient. b An illustration of the expression profile of hub genes obtained from the microarray data verified by RT-qPCR. PBMCs were used to isolate total RNAs and subsequently cDNA for RT-qPCR analysis. The mRNA levels of each gene in healthy donors were considered as 1. DM, Diabetes MellitusBack to article page
