Differential expression analysis of TPD52, PKCε, KLF14 and miRNA 124 in brain cancer subtypes: astrocytomas, glioblastomas, and oligodendrogliomas revealed that the expression of TPD52 and PKCε was up regulated in glioblastomas compared to astrocytomas and oligodendrogliomas (Fig. 6A and B). This evidence concerns the gene KLF14 and astrocytoma (excluding glioblastoma).
