The GLUT family of receptors are often upregulated in different cancers; GLUT-1 is upregulated in a number of cancers [99], GLUT-2 in hepatocellular carcinoma (HCC) [100], GLUT-3 in endometrial cancer [101], GLUT-4 in prostate cancer [102], GLUT 8 in breast cancer [103], and GLUT 12 in breast and prostate cancer [104]. Here, SLC2A1 is linked to breast cancer.
