A Kaplan-Meier survival curve of both REMBRANDT [glioma (Fig. 5a) and astrocytoma (Fig. 5b)] and TCGA data [grade II to IV merged (Fig. 6a) and GBM (Fig. 6b)] showed that different subgroups of PLCβ1 microarray/RNA-Seq expression levels correlate well with patient survival (p < 0.05). This evidence concerns the gene PLCB1 and astrocytoma (excluding glioblastoma).
