EPB41L5 and glioblastoma: To evaluate the role of circ-EPB41L5 in glioblastoma, we detected its expression in several glioblastoma cell lines and found that circ-EPB41L5 is downregulated in glioblastoma cells, especially in U87 and U251, as compared to the normal human astrocytes (NHA) (Figure 2A).
