Several key proteins involved in glycometabolism, such as glucose 6 phosphate dehydrogenase (G6PD), glucose transporter-1 (GLUT-1), demonstrate a higher expression level in BC cells, and their expressions have been reported to positively correlate with the tumor stage (Li et al., 2017; Chen et al., 2018). The gene discussed is G6PD; the disease is neoplasm.
