Fig. 1From: S100A4 suppresses cancer stem cell proliferation via interaction with the IKK/NF-κB signaling pathwayS100A4 was upregulated in MCSCs. a Western blotting analysis of S100A4 protein expression in MCSCs and MB49 cells; β-actin was used as a loading control. b Quantitative PCR of S100A4 mRNA expression in MCSCs and MB49 cells. Transcript levels were normalized to GAPDH, and expressed relative to MB49 cells. Data is mean ± SD of three independent experiments. *P < 0.05Back to article page
