CSF3R and astrocytoma (excluding glioblastoma): In comparison to non-tumoral neural tissue (n = 8), significantly higher levels of CSF3R transcripts were observed in astrocytoma, pilocytic astrocytoma, and glioblastoma (all ps < 0.001; Figure 1; Table 1), whereas oligoastrocytoma and oligodendroglioma did not show significant differences in the French cohort.
