In Supplementary Figure 12b and c, we could observe the increased migration induced by Brg1 overexpression was significantly rescued by Snail knockdown, but not to the normal level (EV group), which means except Snail, other Brg1 targets including the reported E-cadherin that participate in regulating cell migration and tumor metastasis in the gastric cancer setting requires further exploration. The gene discussed is SNAI1; the disease is gastric cancer.
