Fig. 2From: Topoisomerase IIβ mediates the resistance of glioblastoma stem cells to replication stress-inducing drugsCorrelation of Top2β expression and differentiation. The expression of Top2β in NCH421k cells was measured at the indicated time points after ATRA-treatment; GFAP was used as a marker of differentiation, β-actin was used as a loading control. Below the quantification of Top2β expression normalized to actinBack to article page
