Transcriptomic data of LGG patients, grouped based on PREX1 expression (High PREX1 and Low PREX1 in Figure 1A), were mined to identify the potential correlation with PREX1 expression of these astrocytoma essential signaling genes, according to Spearman’s correlation coefficient. Here, PREX1 is linked to astrocytoma (excluding glioblastoma).
