Fig. 7From: Transcriptomics and metabolomics analysis reveal the dietary copper deficiency and supplementation effects of liver gene expression and metabolite change in grazing sheepScreening of the candidate critical genes by WGCNA method. A Network dendrogram from co-expression topological overlap. Color bars show the correlation of gene expression with liver concentration of Cu. B The scatter plot of the association between the turquoise module and gene importance. The genes within the red box are identified as hub genes. C The Venn diagram of overlapping genes between DEGs and the hub genes as candidate critical genes. Abbreviations: WGCNA = the weighted gene co-expression network analysis; DEGs = differentially expressed genes; LCu = the low-Cu feeding group; SCG = the control group for the high-Cu feeding periodBack to article page
