Figure 1. — PER2 expression is downregulated in GSCs. (A) Protein expression levels of NESTIN, CD133 and SOX2 increased in glioma sphere-forming cells line U251s and U87s. (B) Representative images of primary GSCs. (C) Relative mRNA expression of core circadian genes in normal human astrocyte cell, GSCs and matched non-GSCs glioma cell lines. (D) PER2 protein expression in those cell lines. One-way ANOVA with Tukey's post hoc test was used for statistical analysis of the results of B. *P<0.05, **P<0.01 vs. the control. PER2, period 2; GSCs, glioma stem cells.
