HK2 expression. (A) A schema illustrating the functional role of HK2 in the metabolism of FDG (left panel) and a boxplot with the expression level of HK2 in PCs obtained from patients with DWIBS⁺PET⁺, DWIBS⁻PET⁻, and DWIBS⁺PET⁻ imaging results (right panel). (B) The plot shows HK2 expression in PCs stratified by UAMS molecular subgroups.¹¹
