Another interesting target identified was the TSPO -(Translocator protein) that is known to be expressed exclusively in brain cancers, including GBM (65), and can be used for delivering drugs across the blood brain barrier (66) along with DNA topoisomerase I (TOP1), Lipoprotein Lipase (LPL), and DNMT1 (Figure 4C). This evidence concerns the gene TSPO and brain cancer.
