Untargeted metabolomics analysis of serum metabolic signatures as novel biomarkers for gastric carcinoma

Figure 1 Analyses of serum metabolic profiling in patients with gastric carcinoma and healthy controls. ^aP < 0.01. A: Schematic of the study design; B: Partial least squares discrimination analysis score plots show discrimination between the patients with gastric carcinoma (GC) and healthy controls; C: Volcano map of differentially metabolites between the patients with GC and healthy controls; D: Kyoto Encyclopedia of Genes and Genomes pathway enrichment analysis of significantly different metabolites; E: Comparative analysis of the relative levels of the top 10 up-regulated differential metabolites in the serum of 50 patients diagnosed with GC vs 50 healthy control subjects. NS: No significance; GC: Gastric carcinoma; ROC: Receiver operating characteristic; PLS-DA: Partial least squares discrimination analysis; KEGG: Kyoto Encyclopedia of Genes and Genomes.
