Molecular and clinical characterization of GC subtypes in TCGA dataset. A–D Functional enrichment analysis based on 2000 subtype-specific genes (500 specific genes per subtype). E Correlations of GC subtypes with clinical features and previous GC classifications. White denotes missing values. ‘ns’ represents no significance, ^*P < 0.05, ^**P < 0.01, ^***P < 0.001,  ^****P < 0.0001
