Metabolomics of Esophageal Squamous Cell Carcinoma Tissues: Potential Biomarkers for Diagnosis and Promising Targets for Therapy

Figure 7

KEGG pathway enrichment analysis of 269 differential metabolites between esophageal squamous cell carcinoma tissue and adjacent noncancerous tissue. Note: the abscissa is the pathway name and the ordinate is the enrichment ratio, indicating the number of metabolites enriched in this pathway (metabolite number). The ratio of the number of metabolites annotated to the pathway (background number), the ratio, indicates the degree of enrichment. The column color gradient indicates the significance of enrichment, and the darker the default color, the more significant the enrichment represents this KEGG term, where those with value or are labeled as and those with value or are labeled as .
