LINC00470 and astrocytoma (excluding glioblastoma): To further evaluate the clinical significance of LINC00470 in astrocytomas, including GBMs, we found that the levels of LINC00470 were significantly increased in astrocytoma tissues (n = 60) compared with normal brain tissues (n = 12) by RT-qPCR (Fig. 7a), especially in high-grade astrocytomas (Fig. 7b).
