Hypoxic GM-derived (Glioblastoma cell, GM) exosomes have been found to contain significantly elevated levels of the monocarboxylate transporter 1 (MCT1) and its accessory protein differentiation cluster 147 (CD147) that promote the growth, metastasis, and invasion of GMs, as well as angiogenesis, in both in vitro and in vivo experimental models (67, 68). Here, SLC16A1 is linked to glioblastoma.
