Heatmap of correlations between molecular modules and profiles of circulating molecules. Modules of co-expressed probes were obtained from a weighted gene correlation network analysis (WGCNA) from microarray data in the whole blood of 47 growing pigs. The eigengene of each module (ME) was considered as a mathematical representative of the expression levels of the molecular probes within the module. Circulating biochemical molecules were analyzed and the data were summarized by weighted linear correlation using principal component analysis (PCA). The first two dimensions of the PCA were called dim1_met and dim2_met for the metabolites obtained by 1H-NMR high throughput method and dim1_FA and dim2_FA for the fatty acids analyzed by target gas chromatography, respectively
