As shown in Figures 1(a) and 1(c), both the mRNA and protein levels of HMGN5 in glioblastoma samples were higher than nontumoral brain tissues, and also the expression quantity of HMGN5 in the six glioblastoma cell lines was upregulated compared with that in nontumoral brain tissues (Figures 1(b) and 1(d)). Here, HMGN5 is linked to glioblastoma.
