Herein, we further investigated the association between glycolysis and IDO1 in PC with bioinformatic analysis and found the expression of SLC2A1, SLC2A3, SLC2A5 (encoding GLUT1, GLUT3, GLUT5 protein), and IDO1 in the tumor tissues of PC patients was increased compared to the adjacent normal tissues (Figures 6A and S8). Here, SLC2A5 is linked to pachyonychia congenita.
