Furthermore, the IC50 of the inhibitory activity of BBI608 in gastric cancer cells which HOXA11 was induced (NCI-N87-HOXA11: 3.0 μM; SGC-7901-HOXA11: 6.5 μM) were higher than their control ones (NCI-N87-Vector: 0.4 μM; SGC-7901-Vector: 2.8 μM) (Figure S2F). Here, HOXA11 is linked to gastric cancer.
