Fig. 2From: Identification of novel biomarkers affecting the metastasis of colorectal cancer through bioinformatics analysis and validation through qRT-PCRHeatmap for hierarchical cluster analysis of DEG and DEL expression levels change between a, b COAD metastasis and normal tissues (G1); c, d COAD non-metastasis and normal tissues (G2); e, f READ metastasis and normal tissues (G3); g, h READ non-metastasis and normal tissues (G4). The red and green colors represent higher expression levels and lower expression levels of DEGs and DELs, respectivelyBack to article page
