It can be seen from Figure 8 that compared with normal tissues, the expression level of SLC2A12, JDP2, MAFG, SLC2A3, VDAC2, and GCH1 protein was lower in bladder cancer whereas that of RRM2 and SLC3A2 proteins was higher in BC tissues. The gene discussed is GCH1; the disease is urinary bladder carcinoma.
