In this context, monocarboxylate transporters (MCTs), responsible for lactate transport, their chaperones CD147 and CD44, as well as the glucose transporter 1 (GLUT1) and the pH regulator carbonic anhydrase 9 (CAIX) arise as key players in the metabolic reprogramming of cancer cells [27–29]. This evidence concerns the gene SLC2A1 and cancer.
