SOX2 and glioma: Interestingly, expression analysis of some of the selected stemness-associated genes (clear induction of KLF4 and MSI1, slight/partly induction of OCT4, but no induction of SOX2) reflected the observed induction of dormancy-associated ones in a comparable manner (compare Figure 4C/4D and Figure 6A for glioma cell lines, Figure 7A for primary cultures).
