HMGA2 and glioblastoma: The results indicated that several immune cell infiltration levels seemed to be associated with altered HMGA2 gene copy numbers in GBM (upper in Figure 9A; Table 4), including the two highest positive correlation cells: macrophages, Th2 cell infiltration (r = 0.589 and 0.47), and the highest negative correlation cell: plasmacytoid dendritic cell infiltration (pDC cells, r = −0.399) in GBM.
