Expression of Twist1 and its correlation with Bmi1 level in AML cell lines and primary AML samples. (a) Western blotting results of the expression levels of Twist1 protein in the whole cell lysates of two AML cell lines, THP1 and KG1a. β-Actin was used as an internal control. Representative data from three independent experiments are presented. (b) Effects of Twist1-targeted siRNA on the protein levels of Twist1 and Bmi1 in THP1 cells. Twist1-overexpressing THP1 cells were transiently transfected with either Twist1-targeted siRNA or scrambled control for 48 h, and the nuclear lysates were examined by western blotting. Histone 3 was used as a loading control. Representative data from three independent experiments are shown. (c) Positive correlation between Twist-1 and Bmi-1 gene expression in primary AML samples examined by real-time RT-PCR (r=0.5662, P<0.0001, Pearson's correlation).
