SNAI2/Slug mRNA expression was increased more than 9 fold in U87, D566 and T98 human glioma cell lines when compared to non-tumor brain tissues, while the U251 and U343 glioma cell lines showed SNAI2/Slug expression levels similar to those observed in non-tumor brain (Figure 1D). The gene discussed is SNAI2; the disease is glioma.
