Differentiation of lean preAC samples and obese preAC samples by ‘Class II: preAC-DEGs’. a Construction of heatmap accompanied with unsupervised hierarchical clustering. A heatmap coupled with unsupervised hierarchical clustering is generated with a total of 213 ‘Class II: preAC-DEGs’ (P < 0.01) (Additional file 2: Table S1). Refer to the notations in the Fig. 2a legend. b GO analysis of ‘preAC-DEGs’; red and green bars represent upregulated (i.e., genes with higher levels in obese preACs than in lean preACs) and downregulated genes (i.e., genes with lower levels in obese preACs than in lean preACs), respectively. Refer to the Fig. 2b legend for how to select the functional terms and the meaning of the scale on the bottom
