Interestingly, Yang et al. [75] identified a circular RNA encoding circ-FBXW7, whose expression in GBM samples was lower compared to the surrounding normal tissue, being capable of antagonizing the stabilization of the oncoprotein c-MYC initiated by the deubiquitinase USP28; circ-FBXW7 expression was linked to greater survival in patients. Here, FBXW7 is linked to glioblastoma.
