Fig. 1: FAAH is highly expressed in GC tissues.

A Clustered heatmap. Each row represents a tissue sample, and each column represents a coding gene. B Volcano plots. The red points on the right indicate the differentially upregulated genes with statistical significance while the red points on the left indicate the downregulated genes. Differential expression of FAAH in tissues from C TCGA database and D Oncomine database. E Differential expression analysis of FAAH in 4 GC subtypes (data from TCGA). F mRNA levels of FAAH in 96 pairs of GC tissues. G Protein levels of FAAH in 20 pairs of GC tissues. *p < 0.05, ***p < 0.001, ****p < 0.0001. N non-cancerous tissue, C cancerous tissue, CIN tumours with chromosomal instability, EBV tumours positive for Epstein-Barr virus, GS genetically stable tumours, MSI microsatellite unstable tumours.
