After analyzing the expression of RBBP4 mRNA in 33 glioblastoma tissues, we noticed that RBBP4 expression was elevated by 2.5-fold in glioblastoma tissues (Figs. 8d), and RBBP4 expression was negatively related to miR-885-5p expression in glioblastoma tissues (Fig. 8e). Here, RBBP4 is linked to glioblastoma.
