ERBB4 and glioma: The results of co-transfection with si-circ_0001162+ ERBB4 in LN18 cells and circ_0001162+ si-ERBB4 in A172 cells further validated that the effects of circ_0001162 on glioma cell proliferation, migration and invasion were associated with the positive regulation of ERBB4 (Supplementary Figure 3).
