GLUT-1 expression was not detected in normal salivary gland tissues but wasfound mainly in the cytoplasm of pleomorphic adenomas (PAs), adenoid cystic carcinomas (ACCs), and mucoepidermoid carcinomas (MECs) of the salivary glands by de Souza et al. (2017) [59]. Here, SLC2A1 is linked to mucoepidermoid carcinoma.
