GFPT1 expression pattern in public datasets (a). Comparisons of relative GFPT1 mRNA expression between pancreatic ductal adenocarcinoma tissue (from TCGA PAAD datasets) and normal pancreas tissue (from GTEx datasets) were generated at http://gepia2.cancer-pku.cn [16] (b–e). Comparisons of relative GFPT1 mRNA expression between pancreatic ductal adenocarcinoma tissue and adjacent nontumor tissue from GSE16515 (b), GSE28735 (c), GSE56560 (d), and GSE62452 (e). Comparisons (b, c, and e) were conducted by performing Student’s two-tailed t test. Comparison (d) was conducted by performing the Mann-Whitney test because the normality test was not passed. GFPT1, glutamine-fructose-6-phosphate transaminase 1
