As listed in Figure 4B, miRNA-mRNA association analysis revealed that miR-140-5p, miR-148a-3p, miR-148b-3p, miR-328-3p and miR-532-3p were negatively related to GLUT1 mRNA, and miR-19b-3p, miR-193a-3p and miR-199a-5p were positively related to GLUT1 mRNA in PAAD. This evidence concerns the gene SLC2A1 and pancreatic adenocarcinoma.
